Background: Adhesive capsulitis (AC) is often accompanied by pain and restriction in range of movement, which long lasting symptoms often have negative impact on patients' work and lives. Since diabetes mellitus (DM) is an independent risk factor for developing AC, and AC with DM have more limitations of joint motion than general people., Aims: The aim of the present study is to evaluate the difference of clinical efficacy between diabetes and non-diabetes, and to explore whether AC with diabetes need special intervention compared to non-diabetes., Methods: Pubmed NCBI and Embase were searched for studies published in the last 30 years. We conducted a literature search for terms regarding AC and DM on Pubmed NCBI and Embase., Results: A total of 9 studies eligible for inclusion. The affected shoulders in these studies ranged from 26 to 135, 460 shoulders (551 participants) in total, including 166 shoulders in diabetic group and 394 shoulders in non-diabetic/idiopathic group. Interventions included shock wave therapy, hydrodilatation, arthroscopic capsular release, manipulation under cervical nerve root block. Evaluation indicators included pain, certain shoulder questionnaires, range of motion. Positive clinical efficacy were emerged after interventions between the 2 groups. The studies that better improvement of pain in non-diabetic/idiopathic group were 2 of 6, that of certain shoulder questionnaires were 4 of 8, that of range of motion were 3 of 6., Conclusions: Whether AC combined with DM or not, the current treatment could achieve positive clinical effectiveness and there is some statistical evidence show that the curative effect of AC combined with DM is worse than non-diabetic. In other words, the available evidence suggests that patients with DM might require additional rehabilitation measures with routine glycemic control., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Rice body formation is an uncommon, nonspecific inflammatory process. Certain clinical features, such as chronic synovitis associated with rheumatoid arthritis, tuberculous arthritis, and osteoarthritis, can induce a non-specific response that may lead to the development of rice bodies. Currently, the etiological and prognostic significance of rice bodies remains unknown. Magnetic resonance imaging (MRI) is the preferred diagnostic imaging modality for evaluating rice body formation., Case Presentation: The patient, a 44-year-old female, presented with bursitis of the hip joint and the presence of numerous rice bodies. This case is exceptionally rare and unusual as it involves a combination of hip dysplasia and pelvic fracture. The patient underwent a one-stage resection of the rice body, internal fixation of the acetabular fracture, and two-stage total hip arthroplasty, resulting in an immediate improvement in her symptoms. We reviewed the relevant literature and observed that the majority of rice bodies were predominantly found within the capsules of the shoulder and knee joints, while instances of hip joint rice body bursitis were relatively infrequent. To our knowledge, there have been no previous reports documenting a case of hip joint rice body bursitis in conjunction with hip dysplasia and pelvic fracture., Conclusion: This paper presents the rare case of hip joint rice body bursitis combined with hip dysplasia and pelvic fracture, and is one of the highlights., (© 2024.

Objective: To systematically review the clinical efficacy (pain, function, quality of life) and safety of platelet-rich plasma (PRP) in the treatment of frozen shoulder through meta-analysis, and provide evidence-based medical evidence for the effectiveness of PRP in the treatment of frozen shoulder., Methods: A search was conducted on international databases (Pubmed, Web of science, Embase) and Chinese databases (CNKI, Wanfang, VIP) to search the clinical studies on the efficacy of platelet-rich plasma in treating frozen shoulder (adhesive capsulitis/periarthritis/50 shoulder) and their corresponding references published from inception until January 2024. Thoroughly excluded literature not meeting the predetermined inclusion criteria, extracted relevant data from the literature, and input it into RevMan5.4 for meta-analysis., Results: This study ultimately included 14 RCTs, with a total of 1024 patients. The results showed that PRP has significant advantages compared with control groups in VAS (mean difference (MD) =-0.38, 95% confidence interval(CI)(-0.73, -0.03), P = 0.03), UCLA (MD = 3.31, 95% CI (1.02,5.60),P = 0.005), DASH (MD = -4.94,95% CI (-9.34, -0.53),P = 0.03), SPADI (SPADI Total: MD =-16.87, 95% CI (-22.84, -10.91), P < 0.00001; SPADI Pain: MD =-5.38, 95% CI (-7.80, -2.97), P < 0.0001; SPADI Disability: MD =-11.00, 95% CI (-13.61,-8.39), P < 0.00001), and the active and passive Range of Motion (active flexion: MD = 12.70, 95% CI (7.44, 17.95), P < 0.00001; passive flexion: MD = 9.47, 95% CI(3.80, 15.14), P = 0.001; active extension: MD = 3.45, 95% CI(2.39, 4.50), P < 0.00001; active abduction: MD = 13.54, 95% CI(8.42, 18.67), P < 0.00001; passive abduction: MD = 14.26, 95% CI (5.97, 22.56), P = 0.0008; active internal rotation: MD = 5.16, 95% CI (1.84, 8.48), P = 0.002; passive internal rotation: MD = 3.65, 95% CI(1.15, 6.15), P = 0.004; active external rotation: MD = 10.50, 95% CI(5.47, 15.53), P < 0.0001; passive external rotation: MD = 6.00, 95% CI (1.82, 10.19), P = 0.005) except passive extension (MD = 2.25, 95% CI (-0.77, 5.28), P = 0.14). In terms of safety, most studies reported no adverse effects, and only one study reported common complications of joint puncture such as swelling and pain after treatment in both PRP and control groups. Previous studies have shown a risk of osteonecrosis caused by corticosteroids. Therefore, the safety of PRP treatment is more reliable., Conclusion: The results showed that PRP was more durable and safer than corticosteroids and other control groups in the treatment of frozen shoulder., Study Design: Systematic review., Trial Registration: PROSPERO CRD42022359444, date of registration: 22-09-2022., (© 2024.

Background: The aim of this study was to provide comprehensive and reliable evidence for the treatment of pain and motor function in patients with frozen shoulder (FS) with hydrodistension., Methods: The research including randomized controlled trials (RCTs) for FS that compared hydrodistension with routine treatments to controls was searched and screened in the PubMed, Library of congress, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, China Science and Technology Journal Database. Constant-Murley score (CMS) for shoulder function and visual analog scale (VAS) for pain must be assessed. RevMan 5.3 software was used to evaluate the bias and quality of the included studies., Results: We found that analgesic effects (MD: -1.07; 95% CI: -1.94 to -0.20; P < .00001; I2 = 99%) and function (MD: 8.54; 95% CI: 3.35 to 13.71; P < .00001; I2 = 97%) were better in the groups where hydrodistension plus routine treatments were used to treat FS compared to other interventions., Conclusion: The result suggests that hydrodistension is of great clinical significance in alleviating pain and improving function to patients with FS., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Historically, in-person physical therapy serves as a foundational component of nonoperative treatment of adhesive capsulitis (AC). This study compares the effectiveness of an at-home high-intensity stretch (HIS) device to traditional physical therapy (PT) and to PT in combination with the HIS device. We hypothesize that the HIS device will be as effective as PT alone or as combination therapy in the first-line treatment of AC and use of the HIS device will exhibit improvement at higher rate., Methods: Thirty-four patients with idiopathic adhesive capsulitis and a minimum of 12 months follow-up were included in this study. Patients were randomized into one of the three groups: HIS device, PT alone, or HIS device + PT. Passive range of motion (ROM), American Shoulder and Elbow Surgeons (ASES), and Simple Shoulder Test (SST) scores were measured. Additionally, patient satisfaction, compliance and complications were recorded. Paired t-test, ANOVA and Chi-squared tests were used in analysis., Results: Final ROM in all planes improved for all groups compared to baseline (p < 0.001), with only HIS device group able to restore > 95% of contralateral ROM in all planes at final follow-up. Patients with PT alone were on average slowest to improve ROM from baseline, at 3 months, 6 months, and 1 year in all planes except internal rotation. ASES and SST scores improved for all groups when compared to baseline (p < 0.001). Use of HIS-device resulted in greater improvement in SST and ASES Total scores compared to PT alone (p = 0.045, and p = 0.048, respectively)., Conclusions: Use of an at-home high-intensity stretching device for conservative treatment of idiopathic adhesive capsulitis improves outcomes in ROM and in ASES and SST scores both when used as an adjunct to physical therapy and when used alone., Trial Registration: The study protocol was registered at www., Clinicaltrials: gov (20/05/2022, NCT05384093)., (© 2024.

Aim: In rheumatoid arthritis (RA), forefoot bursitis is prevalent, with limited studies comparing ultrasonography (US) and Magnetic Resonance Imaging (MRI). This study aims to evaluate these bursae, providing a comparative analysis of US and MRI, and explore associations with demographic, disease-related factors, pain, clinical examination, and baropodometryin RA patients., Material and Methods: Participants with RA were recruited from the day-hospital clinic. The forefeet were assessed clinically, and the selected foot was examined by US and MRI to evaluate intermetatarsal (IMB) and submetatarsal bursitis (SMB). Baropodometry assessed plantar pressures and contact surfaces., Results: Thirty-five RA patients were enrolled, 85.7% females, mean age 59.2 (11.3) years, mean body mass index (BMI) 26.5 (5.7) kg/m2, median disease duration of 36.0 (16.5-114.0) months, and 34.3% with painful forefoot. A total of 140 intermetatarsal and 175 submetatarsal spaces were evaluated. Agreement between US and MRI was high (PA=97.14%, k=0.801, p<0.001), and interobserver reliability for both modalities was excellent (US: PA=98.73%, k=0.888, p<0.001; MRI: PA=98.41%, k=0.900, p<0.001). IMB was negatively associated with disease duration (the only independent predictor) and linked to clinical signs like the opening toes sign and hammer toe deformity. SMB showed an association with BMI and erosions. Baropodometric analysis indicated no significant differences in plantar pressures for IMB, and larger contact surfaces in SMB regions., Conclusions: US and MRI are valuable tools for forefoot bursitis evaluation. IMB is associated with disease duration (negative association), the opening toes sign, and hammer toe deformity, while SMB correlates with BMI, erosions, and foot architectural deformity. Baropodometry revealed larger contact surfaces in regions with SMB.

An enlarged iliopectineal bursa (IB) can cause pressure on iliofemoral veins. Clinical presentation can manifest as asymmetrical lower extremity edema. This case report demonstrates extensive asymmetrical leg edema caused by femoral vein compression based on iliopectineal bursitis (IB-itis) associated with advanced osteoarthritis (OA) of the left hip joint with an outline of relevant current literature. A female patient presented with left hip pain and edema in the leg. X-ray showed severe OA of the left hip. Computed Tomography (CT) concluded a cystic abnormality at the left iliopsoas muscle associated with the joint consistent with IB-itis, associated with a degenerative left hip joint. Hybrid total hip replacement was performed. At three-month follow-up her left leg showed no longer signs of extensive edema and she walked without the use of walking aids. IB-itis is mostly associated with rheumatoid arthritis (RA). There are no reports which only describe OA as cause of IB-itis. Extensive asymmetrical leg edema can be caused by venous compression of the femoral vein by an IB-itis. If the latter is the consequence of advanced hip OA, a total hip replacement can yield excellent clinical outcomes both functionally and with regard to the edema.

Background: Adhesive capsulitis affects the shoulder joint, causing pain and limiting motion. In clinical practice, the effectiveness of injections varies, and the factors influencing their success remain unclear. This study investigates the predictors of effective corticosteroid injections in patients with primary adhesive capsulitis., Design: This retrospective study enrolled adhesive capsulitis patients older than 35 yrs who received intra-articular corticosteroid injections. The response was determined based on patients' pain and range of motion 3 mos after the injection. Demographic data, medical comorbidities, and radiographic parameters (critical shoulder angle and acromial index) were compared between the effective and noneffective groups. Receiver operating characteristic curves and logistic regression were used to identify the predictors of injection effectiveness., Results: This study included 325 patients with primary adhesive capsulitis, who were divided into responder (189 patients, 58.2%) and nonresponder (136 patients, 41.8%) groups. The receiver operating characteristic curve revealed that the acromial index score indicated favorable discrimination for predicting a poor response to injections, whereas the critical shoulder angle score did not. Logistic regression revealed that the pain period, diabetes mellitus, and acromial index are predictors of nonresponders to injections., Conclusions: Long pain duration, the presence of diabetes mellitus, and an acromial index score greater than 0.711 were predictors of nonresponse to corticosteroid injections for primary adhesive capsulitis patients., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2023 Wolters Kluwer Health, Inc.

Abstract: A 74-year-old man with poorly controlled seropositive rheumatoid arthritis was referred for 18F-FDG PET/CT for follow-up of lung cancer, which demonstrated intense FDG activity in atlantoaxial, sternoclavicular, glenohumeral, and hip joints consistent with active rheumatoid arthritis. There was also unexpected intense uptake at scapulothoracic, ischiogluteal, and trochanteric bursae signifying active bursitis., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: To determine predictive factors associated with a good response (GR) to and efficacy of low-dose radiotherapy (LDRT) in patients with greater trochanteric pain syndrome (GTPS)., Methods: Patients with GTPS were irradiated on a linear accelerator with 0.5-1.0 Gy per fraction to a total dose of 3.0-4.0 Gy per series. The endpoint was subjective good response (GR) to treatment 2 months after completion of the last LDRT series, defined as complete pain relief or marked improvement assessed using the von Pannewitz score. A positive response to steroid injection (SI) was defined as pain relief of at least 7 days. Patient and treatment-related characteristics were evaluated with respect to LDRT outcomes., Results: Outcomes were assessed for 71 peritrochanteric spaces (PTSs; 65 patients, 48 females, with mean age of 63 [44-91] years). Prior SI had been given to 55 (77%) PTSs and 40 PTSs received two series of LDRT. Two months after completion of LDRT, GR was reported in 42 PTSs (59%). Two series of LDRT provided a significantly higher rate of GR than one series (72.5 vs. 42% PTSs, p = 0.015). Temporary pain relief after prior SI predicted GR to LDRT compared with PTSs which had not responded to SI (73 vs. 28% PTSs, p = 0.001). A regional structural abnormality, present in 34 PTSs (48%), was associated with a reduction of GR to LDRT (44 vs. 73% PTSs, p = 0.017)., Conclusion: LDRT is an effective treatment for GTPS. Administration of two LDRT series, prior response to SI, and absence of structural abnormalities may predict significantly better treatment outcomes., (© 2023. The Author(s).)

Background: Diabetes (regardless of type) and obesity are associated with a range of musculoskeletal disorders. The causal mechanisms driving these associations are unknown for many upper limb pathologies. We used genetic techniques to test the causal link between glycemia, obesity and musculoskeletal conditions., Methods: In the UK Biobank's unrelated European cohort (N = 379 708) we performed mendelian randomisation (MR) analyses to test for a causal effect of long-term high glycaemia and adiposity on four musculoskeletal pathologies: frozen shoulder, Dupuytren's disease, carpal tunnel syndrome and trigger finger. We also performed single-gene MR using rare variants in the GCK gene., Results: Using MR, we found evidence that long-term high glycaemia has a causal role in the aetiology of upper limb conditions. A 10-mmol/mol increase in genetically predicted haemoglobin A1C (HbA1c) was associated with frozen shoulder: odds ratio (OR) = 1.50 [95% confidence interval (CI), 1.20-1.88], Dupuytren's disease: OR = 1.17 (95% CI, 1.01-1.35), trigger finger: OR = 1.30 (95% CI, 1.09-1.55) and carpal tunnel syndrome: OR = 1.20 (95% CI, 1.09-1.33). Carriers of GCK mutations have increased odds of frozen shoulder: OR = 7.16 (95% CI, 2.93-17.51) and carpal tunnel syndrome: OR = 2.86 (95% CI, 1.50-5.44) but not Dupuytren's disease or trigger finger. We found evidence that an increase in genetically predicted body mass index (BMI) of 5 kg/m2 was associated with carpal tunnel syndrome: OR = 1.13 (95% CI, 1.10-1.16) and associated negatively with Dupuytren's disease: OR = 0.94 (95% CI, 0.90-0.98), but no evidence of association with frozen shoulder or trigger finger. Trigger finger (OR 1.96 (95% CI, 1.42-2.69) P = 3.6e-05) and carpal tunnel syndrome [OR 1.63 (95% CI, 1.36-1.95) P = 8.5e-08] are associated with genetically predicted unfavourable adiposity increase of one standard deviation of body fat., Conclusions: Our study consistently demonstrates a causal role of long-term high glycaemia in the aetiology of upper limb musculoskeletal conditions. Clinicians treating diabetes patients should be aware of these complications in clinic, specifically those managing the care of GCK mutation carriers. Upper limb musculoskeletal conditions should be considered diabetes complications., (© The Author(s) 2024.

Objectives: The objective of this study was to determine whether the presence of subacromial bursitis in patients with rotator cuff tendinopathy (RCT) was associated with a better outcome after ultrasound (US)-guided subacromial corticosteroid injection., Methods: A single-center prospective study was performed including patients referred for subacromial injection to manage RCT. At baseline, all patients received an US-guided intra-bursal injection of betamethasone (1 ml). The primary endpoint was reduced pain 3 months (M3) after the procedure: a good responder was defined by a decrease in Visual Analogue Scale pain of more than 30%. Secondary endpoints included functional recovery assessed by the Oxford Shoulder Score (OSS) and clinical success at 6 weeks (W6). We also explored the association between good clinical response and other factors, such as US or X-ray features., Results: One hundred patients were included and 49 presented with subacromial bursitis. At M3, 60% of patients (54/100) were considered good responders. The rate of good responders did not differ between the bursitis and non-bursitis groups (p = 0.6). During follow-up, OSS improved over time whether bursitis was present or not. We did not find any US or X-ray features significantly associated with a favorable clinical outcome., Conclusion: The presence of subacromial bursitis did not influence clinical outcomes at 3 months post-subacromial injection in patients suffering from RCT., Clinical Relevance Statement: The presence of subacromial bursitis did not influence clinical outcomes at 3 months post-subacromial corticosteroid injection in patients with rotator cuff tendinopathy. For patient management, looking for ultrasonographic signs of bursitis does not appear relevant for the indication of the injection., Key Points: • Ultrasound-guided subacromial corticosteroid injections led to a significant improvement in 60% of patients suffering from rotator cuff tendinopathy. • The presence of subacromial bursitis was not associated with better improvement at 3 months post-injection. • Except for the Minnesota score referring to job satisfaction, we did not find any baseline clinical, X-ray, or ultrasound characteristics associated with a successful outcome., (© 2023.

Objectives: To evaluate posterior glenohumeral capsule edema compared to other MRI findings in adhesive capsulitis (AC)., Methods: This study was approved by the local Institutional Review Board and it is HIPAA compliant. A retrospective search identified subjects who received fluoroscopically guided intra-articular corticosteroid injections for AC and had an MRI within 6 months prior to injection. The study group was compared with an age-, sex-, and side-matched control group who underwent the same procedures but did not have AC. MRIs were evaluated for edema of posterior capsule, anterior capsule, axillary pouch, coracohumeral ligament (CHL) and rotator interval (RI), thickness of axillary pouch and CHL, thickness of anterior capsule, RI and subcoracoid fat replacement, and teres minor atrophy and edema. Multivariable analysis was performed., Results: A total of 57 subjects with AC and 57 matched controls were studied: mean age 52 ± 7 (range 31-71) years, 37 female and 20 male, 22 right and 35 left. Posterior capsule edema was more common in the AC group vs. control group (66.7 vs 17.5%, p < 0.001). Multivariable analysis showed posterior capsule edema, CHL edema, and axillary pouch (glenoid) thickness (optimum cutoff = 4 mm) were significant independent predictors of AC. Simplified analysis using these three variables had an area under the curve of 0.860 (95%CI: 0.792-0.928). With all three variables present, the sensitivity and specificity for AC were 32% and 98%, respectively., Conclusions: Posterior joint capsule edema may be helpful to confirm AC. Posterior capsule edema, CHL edema, and axillary pouch (glenoid) thickness produce a strong model for distinguishing AC from controls., Clinical Relevance Statement: Edema involving the posterior shoulder joint capsule is an imaging marker of capsulitis and is useful in differentiating patients with adhesive capsulitis from those without in conjunction with other proven MRI findings., Key Points: • Posterior capsule edema has a sensitivity of 66.7% and a specificity of 82.5% for the detection of adhesive capsulitis. • Posterior capsule edema, coracohumeral ligament (CHL) edema, and axillary pouch (glenoid) thickness were significant independent predictors of adhesive capsulitis, and combining these variables together produces a very strong model for distinguishing cases from controls (AUC = 0.860). • Optimal cutoff values for CHL, axillary pouch (humeral), axillary pouch (glenoid), and axillary pouch (total) thickness were 2.5, 2.6, 4, and 6.3 mm, respectively., (© 2023.

Background: Frozen shoulder (FS) is characterized by shoulder pain and restricted movement of the shoulder joint. While it tends to resolve on its own, it significantly affects an individual quality of daily life. The pure acupotomy technique employs needle-knife manipulation as the sole treatment, without the use of medications, such as steroids or vitamins, and local anesthesia if necessary. It aims to restore soft tissue mechanical balance and circulation through techniques such as cutting and stripping, creating a "gap effect." This technique can rapidly, safely, and effectively relieve functional impairments in patients with FS. This article presents a case study of the successful treatment of FS using a purely needle-knife technique., Patient Concerns: The patient, aged 57 years, presented with chronic pain in the right shoulder, which was particularly aggravated at night, and moderate limitations in joint mobility., Diagnoses: The patient was diagnosed with periarthritis of the right shoulder (moderate FS, frozen period), type 2 diabetes, and supraspinatus tendinitis of the right shoulder., Interventions: Conventional treatments, such as topical analgesics and acupuncture, produced insignificant improvements in symptoms. So, the patient chose acupotomy treatment and signed the treatment consent form., Outcomes: After undergoing one minimally invasive acupotomy treatment, the patient experienced immediate restoration of normal shoulder joint mobility and a significant reduction in pain intensity 3 days post-treatment., Lessons: We believe that utilizing a purely acupotomy treatment for passive functional impairments in FS not only yields good results but also saves patients time and reduces their financial burden. This is worth promoting extensively in clinical practice., (Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.)

We present a case of a patient who underwent a modified scarf osteotomy and tumour excision based on a preoperative diagnosis of hallux valgus deformity and accompanying bursitis. Subsequent histopathological examination revealed that the tumour was an angioleiomyoma. While tumours around the first metatarsophalangeal (MTP) joint are typically associated with gouty nodules, infections, or swollen bursa (bursitis) in patients with hallux valgus deformity, the occurrence of soft tissue tumours in this area is rare. Moreover, angioleiomyoma is an even rarer form of soft tissue tumour and is seldom suspected prior to resection. To our knowledge, there have been no reports of angioleiomyoma arising in the first MTP joint. However, it is important to consider the possibility of an atypical tumour in cases where soft tissue masses are present, even in patients with hallux valgus deformity, and to perform at least imaging tests such as ultrasound and magnetic resonance imaging before surgery. This prospect should always be kept in mind., (© Japan College of Rheumatology 2023. Published by Oxford University Press. All rights reserved.

Introduction: Previous studies have suggested a positive association between adhesive capsulitis of the shoulder (ACS) and Parkinson's disease (PD), but longitudinal data were lacking. The present population-based longitudinal follow-up study therefore investigated the risk of developing PD in patients with ACS., Methods: This study utilized data from Taiwan's Longitudinal Health Insurance Database 2005 (LHID 2005). We defined our ACS group as the 19,920 patients aged between 40 and 79 who had been diagnosed with ACS between 2002 and 2006. The non-ACS group consisted of an age- and sex-matched but otherwise random selection of 19,920 patients without a diagnosis of ACS. The Kaplan-Meier method was then used to examine inter-group differences in PD-free survival rates, and Cox proportional-hazard regression modeling was used to evaluate the impact of ACS on PD risk., Results: During a median follow-up period of 105 months, 242 subjects in the ACS group and 208 subjects in the non-ACS group developed PD. The adjusted hazard ratio (HR) of 1.53 (1.26-1.86) indicated that ACS patients had a significantly higher risk of developing PD than their non-ACS counterparts, regardless of sex and age. Landmark analysis that excluded PD cases detected within the first 2 years after an ACS diagnosis showed that the HR was almost unchanged, at 1.56 (1.26-1.95)., Conclusions: Patients with ACS are at a high risk of developing PD., Key Points: • This population-based study showed that adhesive capsulitis of the shoulder (ACS) is associated with a higher risk of Parkinson's disease (PD). • This study broke new ground by using a longitudinal follow-up design and a nationally representative sample. • Our findings suggest that clinicians who care for ACS patients need to be aware of this increased risk of developing PD., (© 2023.

To evaluate the relationship of ultrasonographic evaluation parameters with pain, muscle strength and disease severity in lateral epicondylitis (LE). 64 people were included in present retrospective, cross-sectional study. Activity and rest pain was questioned with Visual Analog Scale (VAS). Also, Patient Rated Tennis Elbow Evaluation (PRTEE) and the maximum grip strength were evaluated. Hypoechoic region, neovascularity, cortical irregularity, enthesopathy and peritendinous fluid or bursitis were evaluated by ultrasonography. 48 of the patients were female and 16 were male. Mean age was 48.53 ± 6.12, body mass index was 27.70 ± 4.75. 55 (85.9%) hypoechoic region, 31 (48.4%) neovascularity, 21 (32.8%) cortical irregularity, 19 (29,7%) enthesopathy, and 18 (28.1%) peritendinous fluid or bursitis were detected by ultrasonography. When the ultrasonographic findings and clinical findings of the patients were compared, no significant difference was found between the hypoechoic region, cortical irregularity, enthesopathy and clinical findings (P > .05), while the extension grip strength was found to be significantly lower in patients with neovascularity (P = .045). In addition, patients with peritendinous fluid or bursitis, were found to be significantly lower in both flexion (P = .033) and extension (P = .023) grip strength, while PRTEE function (P = .021) subgroup and total (P = .038) scores were significantly higher. Hypoechoic region, cortical irregularities and enthesopathy were not evaluated to be associated with disease severity, pain and muscle strength. Neovascularity was found to be associated only with extension grip strength. Peritendinous fluid or bursitis was found to be associated with both flexion and extension grip strength and disease activity, but not associated with pain., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Objective:  Adhesive capsulitis is a condition characterized by shoulder pain and stiffness. Breast cancer treatment has been linked to the development of this condition, but its mechanisms are still little known. This study's objective was to identify predictors factors associated with the development of adhesive capsulitis in breast cancer patients., Methods:  A case control study was performed with women undergoing treatment for breast cancer in a single center. The sampling was nonprobabilistic and consecutive. Adhesive capsulitis was defined as constant pain associated with decreased active and passive shoulder movement in anterior elevation, external rotation at 0°/90° abduction, and internal rotation at 90° abduction. The study group consisted of patients with shoulder pain and range of motion limitations, while the control group consisted of women without any shoulder abnormalities. Sociodemographic and clinical variables were collected. A univariate logistic regression was used to assess the influence of variables on the studied outcome. For p  < 0.20, a multivariate logistic regression was used. The probability of null hypothesis rejection was 5%., Results:  A total of 145 women were assessed, with 39 (26.9%) on the study group and 106 (73.1%) on the control group. The majority was under 60 years old. In the multivariate analysis, variables correlated to the outcome under study were shoulder immobilization (OR = 3.09; 95% CI: 1.33-7.18; p  = 0.009), lymphedema (OR = 5.09; 95% CI: 1.81-14.35; p  = 0.002), and obesity (OR = 3.91; 95% CI: 1.27-12.01; p  = 0.017)., Conclusion:  Lymphedema, postsurgery immobilization, and obesity are predictive factors for the development of adhesive capsulitis in breast cancer patients., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Background: Primary idiopathic adhesive capsulitis (AC) is characterized by shoulder pain and global limitations in range of motion (ROM). The aim of this study was to determine (1) if a spectrum of symptom severity exists during the freezing phase of AC and (2) identify factors associated with patient selection of corticosteroid injection (CSI) for treatment., Methods: Patients presenting within 6 months of symptom onset of AC (freezing phase) were enrolled in this single-site retrospective case control study. Visual analog pain scale (VAS) score, shoulder ROM, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, and Patient-Reported Outcomes Measurement Information System (PROMIS function and pain) scores were collected. Each patient was offered oral anti-inflammatory medication, physical therapy, and intra-articular CSI. Patients were divided into 2 cohorts: those electing vs. those deferring CSI. Multivariable logistic regression was performed to identify patient or symptom characteristics predictive of electing CSI., Results: A total of 112 patients (mean age = 54.7 ± 8.8 years, female = 76 [67.9%], mean symptom duration = 13.2 ± 7.9 weeks, elected CSI = 74 [66.1%]) were included in our analysis. The overall study population demonstrated a wide spectrum of VAS pain scores (6.0 ± 2.8, range: 0-10) and ROM: forward elevation (99° ± 27°, range: 30°-150°), abduction (82° ± 24°, range: 30°-130°), external rotation (47° ± 13°, range: 0°-90°), internal rotation (38° ± 26°, range: 5°-90°). The CSI group had higher mean VAS pain score (6.6 ± 2.5 vs. 4.9 ± 3.0, P = .005) and greater limitations in ROM for forward elevation (92° ± 27° vs. 113° ± 25°, P = .001) and abduction (77° ± 24° vs. 90° ± 21°, P = .005) compared with the non-CSI cohort. The CSI group demonstrated significantly worse shoulder function based on Constant (P < .05), ASES (P = .001), P-UE (P = .016), P-Intensity (P = .002), and P-Interference (P = .004). Logistic regression demonstrated decreased total shoulder ROM in forward elevation and abduction plane (OR = 0.98, 95% CI = 0.97-0.99, P = .004). Hispanic ethnicity and increased VAS pain score (OR = 1.20, 95% CI = 1.01-1.43, P = .04) were associated with increased likelihood of electing CSI., Conclusion: A spectrum of symptom severity exists during the freezing phase of primary AC, despite similar etiology. AC patients with greater pain severity, and greater limitations in ROM at initial evaluation were associated with patient selection of CSI., (Copyright © 2023 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: A diseased shoulder due to pain, stiffness, or weakness negatively affects patients' quality of life and their ability to carry out activities of daily living. Adhesive capsulitis is a disease characterized by shoulder pain and global limitation of movement in the shoulder joint. Many interventions have been proposed for the treatment of primary adhesive capsulitis. The current study compares the effect of ultrasound-guided intraarticular injection of ozone versus steroid versus intraarticular application of pulsed radiofrequency., Objectives: The primary outcome of the current study was to compare the improvement in the Visual Analog Scale (VAS) after the 3 treatment modalities. The secondary outcomes included functional improvement measured by the Shoulder Pain and Disability Index (SPADI) and level of inflammatory biomarkers measured by serum intercellular adhesion molecule (ICAM-1) and high-sensitivity C-reactive protein(hs-CRP)., Study Design: The current study is a prospective, double blinded, randomized controlled trial. We employed a double blinding technique for both the patients and the outcome assessors., Setting: Our study was carried out at the Medical Research Institute, Alexandria University, Egypt, after approval of the local ethical committee (IORG0008812). The study was registered in the "clinical trials library for protocol registration and results system" with number NCT04724317.The study included 45 patients with a diagnosis of primary adhesive capsulitis., Methods: Patients were randomly assigned to 3 equal groups: steroid group, ozone group, and pulsed radiofrequency group. Pain and global shoulder functions were assessed using the VAS at rest and with movement, range of motion (ROM), and the SPADI. Moreover, ICAM-1 and hs-CRP were measured as inflammatory markers., Results: The results of the current study reveal that all patients in all groups have had a statistically significant improvement after their intervention regarding pain, disability, ROM, and inflammatory markers. Pairwise comparisons revealed that improvement of the VAS during movement had a statistically significant improvement starting from the second week and continuing to the fourth and eighth week. VAS during rest had a significant improvement starting from follow-up week one in the steroid group. Moreover, improvement in the ROM and SPADI scores started from the second week follow-up. Percent improvement was calculated for each group and there was a statistically significant difference between groups in VAS at rest and ROM in the pulsed radiofrequency group compared to the steroid group.Regarding inflammatory markers, both ICAM-1 and hs-CRP had a significant improvement after all 3 interventions with no statistically significant difference among the groups., Limitations: This study is a single-center study. A shortage of previously published data, and heterogeneity in the published methodology of the 3 interventions limited our discussion data for comparison with the previous literature., Conclusion: Ultrasound-guided shoulder joint intraarticular injection of steroid, ozone, or pulsed radiofrequency application all result in a significant improvement in pain, disability, and ROM in primary adhesive capsulitis. They can be used as an effective treatment modality for this condition. Comparing groups statistically, the pulsed radiofrequency group had a more delayed, but statistically better long-term improvement compared to the other 2 groups.

Background and Objectives: Post-COVID-19 syndrome is commonly used to describe signs and symptoms that continue or develop after acute COVID-19 for more than 12 weeks. The study aimed to evaluate a treatment strategy in patients with adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome. Materials and Methods : The method used was an interventional pilot study in which 16 vaccinated patients presenting with the clinical and ultrasound features of adhesive capsulitis (phase 1) developed during post-COVID-19 syndrome were treated with infiltrative hydrodistension therapy under ultrasound guidance associated with early rehabilitation treatment. Results: Sixteen patients with post-COVID-19 syndrome treated with ultrasound-guided infiltration and early rehabilitation treatment showed an important improvement in active joint ROM after 10 weeks, especially in shoulder elevation and abduction movements. The VAS mean score before the treatment was 6.9 ± 1.66. After 10 weeks of treatment, the VAS score was 1 ± 0.63. Conclusions: The study demonstrated that the management of adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome, as conducted by physiotherapists in a primary care setting using hydrodistension and a rehabilitation protocol, represented an effective treatment strategy.

Autism spectrum disorder (ASD) is an increasingly common neurodevelopmental disorder associated with impairments in postural control and repetitive patterns of behavior. Here, we describe two cases of adventitial bursitis of the dorsolateral feet in patients with ASD presenting as mass-like lesions. Both patients habitually sat in the W-position and were treated with ultrasound-guided aspirations with immediate relief of symptoms., (© 2022.

Background: Many treatment strategies have been described for the management of frozen shoulder. However, to date no randomized controlled trial has directly compared the efficacy of exercise and oral corticosteroids. The aim of this study was to determine whether pain, range of motion (ROM), and function differ between patients with frozen shoulder randomized to treatment with exercise or oral corticosteroids., Methods: This prospective, randomized, assessor-blinded trial was performed to compare the effectiveness of exercise and oral corticosteroids in patients with frozen shoulder. Overall, 33 patients with frozen shoulder were randomly assigned to receive either exercise (n = 17) or oral corticosteroids (n = 16). The exercise was applied 2 times per week for 6 weeks for 12 visits; patients in the oral corticosteroids group received prednisolone for 4 weeks. Participants were assessed at baseline, after 6 weeks and at the 12-week follow-up. The primary outcome was the Disabilities of the Arm, Shoulder and Hand and visual analog scale. Secondary outcomes were American Shoulder and Elbow Surgeons Standardized Shoulder Assessment, ROM, and Hospital Anxiety and Depression Scale. Repeated-measures analysis of covariance with baseline scores as the covariates was used to determine between-group differences. An intention-to-treat analysis was performed using the multiple imputation method to impute values for all missing data., Results: Planned pairwise comparisons demonstrated significant improvements in pain relief and functional outcomes in both groups at the 6- and 12-week follow-ups compared to baseline. There were no significant time-by-group interactions between-group differences noted for the Disabilities of the Arm, Shoulder and Hand (F = 0.470, P = .93), visual analog scale (F = 0.006, P = .94), flexion ROM (F = 2.78, P = .1), internal rotation ROM (F = 3.440, P = .07) and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment (F = 0.470, P = .49). The overall group-by-time interaction for the 2 × 3 mixed-model analysis of covariance using baseline scores as a covariate was significant for the abduction range (F = 4.460, P = .04) and external rotation ROM (F = 12.100, P = .002) in favor of the exercise group., Conclusions: The study demonstrated that while both groups achieved significant improvements at the 6-, and 12-week follow-ups, the exercise group was superior in terms of abduction and external rotation ROM. Additionally, even though both groups were improved, the effect sizes were larger in the exercise group. Considering the systemic side effects of oral corticosteroids, even at low doses, a well-planned exercise program that considers pain may be a good option for frozen shoulder., (Copyright © 2023 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: Preliminary data suggest that women with breast cancer are at particularly high risk of adhesive capsulitis of the shoulder. Therefore, this study aimed to investigate the potential association between breast cancer and adhesive capsulitis in adults from Germany., Methods: This retrospective cohort study included all women aged ≥ 18 years who were diagnosed for the first time with breast cancer in one of 1,274 general practices in Germany between January 2000 and December 2018 (index date). Women without breast cancer were matched (1:1) to those with breast cancer using a propensity score based on age at the index date, index year, and the average number of medical consultations per year during the follow-up. In women without breast cancer, the index date was a randomly selected visit date between 2000 and 2018. The association between breast cancer and the 10-year incidence of adhesive capsulitis was studied using Kaplan-Meier curves and a Cox regression model adjusted for age and several comorbidities., Results: There were 52,524 women included in this study (mean [SD] age 64.2 [12.9] years). The 10-year incidence of adhesive capsulitis was 3.6% in both the group with and the group without breast cancer (log-rank p-value = 0.317). The Cox regression analysis further showed no significant association between breast cancer and adhesive capsulitis (HR = 0.96, 95% CI = 0.86-1.08)., Conclusion: In this sample of women from Germany, breast cancer was not significantly associated with adhesive capsulitis. Although the present preliminary findings are reassuring, general practitioners should regularly assess shoulder function in breast cancer survivors., (© 2023.

Adhesive capsulitis, colloquially known as "frozen shoulder," is a relatively common disorder, affecting approximately 2% to 5% of the general population. The incidence may be higher as the condition can be relatively mild and self-limited and thus many patients who experience it may never present for treatment. It involves a pathologic process of gradual fibrosis of the glenohumeral joint that leads to limited active and passive range of motion, contracture of the joint capsule, and shoulder pain., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2022 Elsevier Inc.

Background: The rotator cuff is a group of muscles and tendons which support the shoulder joint. Rotator cuff disease is a frequent cause of morbidity in adulthood., Aims: The aims of his study are to determine the prevalence and patterns of rotator cuff derangement in symptomatic patients using MRI and to attempt to correlate identified patterns of disease with age and gender METHODS: Five hundred ninety-seven patients attending for MRI of the shoulder with atraumatic shoulder pain were included for study. Patients' age and gender was recorded. Record was made of the presence or absence of rotator cuff derangement and of degenerative change in the AC and glenohumeral joints. Correlation was made between age and gender., Results: There were 358 males (60%) and 239 females (40%) with a mean age of 49.4 ± 17.1 years. Subacromial bursitis was identified in 517 patients. A normal supraspinatus tendon was identified in 219 patients and supraspinatus full thickness tearing was identified in 102 patients. A normal AC joint was identified in 267 patients while degenerative AC joint changes were identified in 370 patients. A significant correlation was identified between age and rotator cuff derangement (p < .001) and between age and AC joint derangement (p < .001). No significant difference was identified between gender and patterns of cuff derangement CONCLUSION: The extent of rotator cuff and AC joint derangement increases with ageing. Impingement appears to trigger a cascade of events in sequence, from isolated subacromial bursitis through to supraspinatus tendon tearing. Patterns of rotator cuff derangement are similar in men and women., (© 2022. The Author(s).)

Purpose: Bursitis is a common musculoskeletal cause of shoulder pain and treatment varies, thus correctly diagnosing and grading bursitis is paramount in deciding management. Our aim was to assess reliability in grading shoulder bursitis on ultrasonography among fellowship trained musculoskeletal radiologists at our institution. Methods: Retrospective study of patients diagnosed with bursitis on ultrasonography. Single-sonographic images of the subacromial-subdeltoid bursa were collected for each patient and randomized to form a test-bank of varying degrees of bursitis. Three months after the test was administered, the cases were randomized and readministered. The radiologists graded each case as: within normal limits, mild, moderate or severe. Intraobserver variability was measured using Cohen's kappa coefficient. Linear regression model was performed to assess correlation between years of experience and kappa. Results: 10 radiologists reviewed 70 cases of bursitis. Kappa values ranged from .53 to .91, indicating 'moderate' to 'almost perfect' variability amongst radiologists. A moderate positive correlation of improving variability ( r = .69) with increasing years of experience exists. Conclusion: Fellowship trained musculoskeletal radiologists were able to grade shoulder bursitis with moderate to almost perfect variability, with a positive correlation of improved variability with increasing experience. This may help clinicians choose the correct treatment more confidently in their patients with shoulder pain.

We experienced a case of bilateral shoulder bursitis with gas images in a rheumatoid arthritis (RA) patient. A 60-year-old man with RA had been treated with weekly methotrexate 10 mg and daily prednisolone (PSL) 10 mg for 7 months. Generalized pain, especially in the bilateral shoulder joints, developed and exacerbated daily with increased C-reactive protein (CRP) level. Despite the initiation of biweekly sarilumab 200 mg, joint symptoms and CRP level continued to worsen. Computed tomography (CT) scan to determine the cause of severe shoulder inflammation revealed low absorption areas with contrast effects at the margins around the bilateral shoulder joints, accompanied by internal gas images. In addition, magnetic resonance imaging demonstrated subacromial bursae and coracoid bursae and bursitis, leading to the suspicion of abscess formation depending on the presence of gas image. In spite of antimicrobial therapy, arthralgia did not improve, and a CT-guided arthrocentesis of the left shoulder joint resulted in negative findings of infection in culture and pathological examinations. Switching treatment to intensive anti-inflammatory therapy with high-dose steroids and etanercept finally improved symptoms and CRP levels associated with the reduction of low absorption areas and disappearance of gas images at bilateral shoulder joints. Our case indicated that bursitis with gas image in RA patients involves unusual pathophysiology and requires intensive anti-rheumatic treatment., (© Japan College of Rheumatology 2022.

The risk of tuberculosis (TB) increases in immunocompromised patients. Multiple myeloma is considered a risk factor for TB and myeloma patients with TB have a higher mortality rate than those without TB. Herein, we report a case of concomitant TB of the iliotibial band mimicking a soft tissue tumor and tuberculous trochanteric bursitis in a patient with multiple myeloma. In this article, the characteristic magnetic resonance imaging (MRI) findings were low T2 signals in the cystic fluid lesion, a dark T2 signal rim, and peripheral rim enhancement. These results could help differentiate TB of the iliotibial band and trochanteric bursitis from other pathologies. If the abovementioned findings were observed in immunocompromised patients, extrapulmonary TB may be expected even if chest radiographs are normal., (© 2022.

Introduction: Shoulder capsulitis (SC) is a common musculoskeletal complication in patients with diabetes. It can be particularly disabling. It is often overlooked by clinicians. The aim of this study is to evaluate the prevalence of retractile capsulitis and to identify the risk factors in a population of Moroccan diabetic patients., Materials and Methods: We realised a cross-sectional study including patients with diabetes mellitus (DM). We recorded the demographic and diabetic characteristics of our patients. SC and vascular complications were assessed by clinical and para-clinical investigations. The prevalence of SC was calculated. The factors associated with SC were evaluated by suitable statistical tests., Results: Three hundred and Sixty-five patients were included; 84.9% had Type 2 DM (T2DM). The mean age of the participants was 52.6 ± 13.6. Shoulder capsulitis was present in 12.6% of patients. In statistical analysis, age >50 years (P = 0.001), T2DM (P = 0.03), duration of progression >10 years (P = 0.03), dyslipidemia (P = 0.013) and macrovascular complications (P = 0.009) were associated with an increased frequency of SC., Conclusion: This study shows that the prevalence of SC is higher in diabetic patients. Therefore, inclusion of this pathology in the global management of the diabetic patient is necessary., Competing Interests: None

Background: External snapping hip syndrome (ESH) is postulated to be one of the causes of greater trochanteric pain syndrome, which also includes greater trochanteric bursitis and tendinopathy or tears of the hip abductor mechanism. However, it was not yet described what kind of bony morphology can cause the snapping and whether symptomatic and asymptomatic individuals have different imaging features., Purpose: It was the purpose of this study to look for predisposing morphological factors for ESH and to differentiate between painful and asymptomatic snapping., Methods: A consecutive cohort with ESH and available magnetic resonance imaging (MRI) between 2014 and 2019 was identified. The control group consisted of patients that underwent corrective osteotomies around the knee for mechanical axis correction and never complained of hip symptoms nor had undergone previous hip procedures. The following parameters were blindly assessed for determination of risk factors for ESH: CCD (corpus collum diaphysis) angle; femoral and global offset; femoral antetorsion; functional femoral antetorsion; translation of the greater trochanter (GT); posterior tilt of the GT; pelvic width/anterior pelvic length; intertrochanteric width. Hip and pelvic offset indexes were calculated as ratios of femoral/global offset and intertrochanteric/pelvic width, respectively. For the comparison of symptomatic and asymptomatic snapping, the following soft-tissue signs were investigated: presence of trochanteric bursitis or gluteal tendinopathy; presence of surface bony irregularities on trochanter major and ITB (Iliotibial band) thickness., Results: A total of 31 hips with ESH were identified. The control group (n = 29) consisted of patients matched on both age (± 1) and gender. Multiple regression analysis determined an increased hip offset index to be independent predictor of ESH (r =  + 0.283, p = 0.025), most likely due to the higher femoral offset in the ESH group (p = 0.031). Pearson correlation analysis could not identify any significant secondary factors. No differences were found between painful and asymptomatic snapping on MRI., Conclusions: A high hip offset index was found as an independent predictor for external snapping hip in our cohort, mainly due to increased femoral offset. No imaging soft-tissue related differences could be outlined between symptomatic and asymptomatic external snapping., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Purpose: To present the preliminary results of a cohort of 13 patients with hip osteoarthritis (OA) and great trochanteric pain syndrome (GTPS) refractory to conservative management or physical therapy and no indication for surgery treated with embolization of the lateral femoral circumflex artery., Material and Methods: This is a single-center prospective cohort from July 2019 to September 2020. Visual analogue scale (VAS) and Western Ontario and MacMaster Universities (WOMAC) were used to compare the symptoms before and after 6-month follow-up. Technical success was considered when at least one artery responsible for the hyperemic synovium was embolized. Complications and adverse events were noted., Results: In total, 13 patients were included; mean age was 62.4 (± 11.0) years. 10 (76.9%) patients were treated for GTPS and 3 (23.1%) for hip OA. Nine patients were treated with imipenem/cilastatin (I/C) alone. Microsphere 100-300 μm and I/C were combined in 4 patients. The WOMAC Index had a statistically significant decrease in the total from 77 to 27 points (p = 0.001). Pain, rigidity and physical activity have also significantly reduced (19 to 5, p = 0.001; 6 to 2, p = 0.002 and 53 to 22, p = 0.001, respectively). VAS score had a significant decrease (10 to 2, p = 0.002). Two patients present posterior tight numbness, spontaneously improved within 30 days., Conclusion: In this cohort, lateral femoral circumflex artery embolization was a safe and effective treatment for patients with hip pain due to OA and GTPS., (© 2022.

Objectives: The pathophysiology of a frozen shoulder (FS) is thought to be related to chronic inflammation. Chronic inflammation may disturb the immune system and consequently the nervous system as part of an overarching system. The aim of this study was to determine the presence of disturbed autonomic nervous system function and altered central pain processing (CPP) in patients with FS. Secondarily, the presence of psychological variables (catastrophizing and hypervigilance) and self-reported associated symptoms of altered CPP in patients with FS were investigated., Methods: Patients with FS and healthy controls completed the Composite Autonomic Symptom Score (autonomic function) and underwent quantitative sensory testing to assess tactile sensitivity (ie, allodynia), pressure pain thresholds (PPTs, ie, hyperalgesia), temporal summation of pain, and Conditioned Pain Modulation (CPM). Psychological issues were explored with the Pain Catastrophizing Scale and the Pain Vigilance and Awareness Questionnaire, and self-reported symptoms associated with altered CPP were determined with the Central Sensitization Inventory., Results: Thirty-two patients with FS and 35 healthy controls were analyzed in the study. Patients with FS showed more self-reported autonomic symptoms and symptoms of altered CPP, higher levels of pain catastrophizing and hypervigilance, and are more sensitive to tactile touches and mechanical pressure compared with controls., Discussion: On the basis of the effect sizes, between-group differences in allodynia, hyperalgesia, catastrophizing, and hypervigilance were clinically relevant, but only local allodynia, hyperalgesia, catastrophizing, and hypervigilance were statistically different. Therefore, obvious altered CPP was not present at the group level in patients with FS compared with controls., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Musculoskeletal pain is common in hemodialysis (HD) patients and may be related to articular or periarticular amyloid deposition. The shoulder is one of the most common afflicted joints, but not all causes of shoulder pain are detectable on radiography, and magnetic resonance imaging (MRI) is not always available. The aim of this study was to evaluate the validity of musculoskeletal ultrasound (MSUS) to properly detect shoulder disorders in HD patients by identifying US abnormalities in the shoulder and comparing them to those identified on MRI, with MRI serving as the gold standard test., Methods: This cross-sectional observational study was conducted on 28 HD patients (16 males and 12 females, mean age 46.89) with either unilateral or bilateral shoulder pain. Demographic data and clinical characteristics were recruited. All patients were subjected to clinical assessment, MSUS and MRI of both shoulders., Results: US abnormalities were prevalent in almost all patients. Supraspinatus tendinopathy was the most common abnormality in symptomatic shoulders (92.1%), followed by subacromial-subdeltoid (SASD) bursitis (65.8%), humoral erosions (57.9%), and acromioclavicular joint (ACJ) osteoarthritis (52.6%). MSUS shows high sensitivity and specificity when compared to MRI in all the studied shoulder pathologies except glenohumeral joint (GHJ) effusion (sensitivity, 33.3%) and infraspinatus tendinopathy (sensitivity, 58.3%). The percentage of agreement between MSUS and MRI in detecting biceps tenosynovitis was 82.14% (kappa, 0.64), subscapularis tendinopathy 83.93% (kappa, 0.654), supraspinatus tendinopathy 91.07% (kappa, 0.617), infraspinatus tendinopathy 82.14% (kappa, 0.470), SASD bursitis 80.36% (kappa, 0.569), humeral head erosions 82.14% (kappa, 0.635), GHJ effusion 82.14% (kappa, 0.352), and ACJ osteoarthritis 76.79% (kappa, 0.539)., Conclusions: Shoulder problems are common in HD patients, even in people who do not have obvious shoulder complaints. MSUS is a valuable imaging technique that assists in the diagnosis of HD patients who report shoulder pain., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Samar Tharwat et al.)

Background: Thyroid functional abnormalities are considered risk factors for idiopathic adhesive capsulitis (IAC) though that relationship remains uncertain. Although dyslipidemias are associated with IAC, no readily accessible study has reported associations between dyslipidemias and IAC patients with subclinical hypothyroidism. The purposes of this study were to investigate whether subclinical hypothyroidism is an independently associated factor for IAC and to determine the differences in prevalence of dyslipidemias between two groups of persons with subclinical hypothyroidism: one composed of IAC patients and the other of individuals without IAC., Methods: This case-control study included a case group of 412 IAC patients without intrinsic shoulder lesions, extrinsic causes, or medication for thyroid dysfunction. The control group comprised 1236 age- and sex-matched persons seeking general checkups at the authors' health promotion center during the same period as the case group. Control subjects had normal shoulder function and no previously diagnosed adhesive capsulitis, no medication for thyroid dysfunction, and no history of trauma or of shoulder surgery. The studied variables were age, gender, obesity, diabetes, dyslipidemias, subclinical hypothyroidism, hypothyroidism, and hyperthyroidism. A conditional logistic regression analysis evaluated the matched sets of subjects to determine odds ratios and 95% confidence intervals for the studied variables. The differences in the prevalence of dyslipidemias between IAC patients with subclinical hypothyroidism and individuals with subclinical hypothyroidism but without IAC were determined with generalized estimating equations, using covariates of age, sex, and diabetes. The P values were set at < 0.05., Results: Subclinical hypothyroidism (odds ratio, 2.10; 95% confidence interval, 1.36-3.15; P = .001) was significantly associated with IAC. Patients with IAC and subclinical hypothyroidism had a significantly higher prevalence of hyper-low-density lipoproteinemia, an inflammatory lipoproteinemia, than individuals with subclinical hypothyroidism but without IAC (P = .002)., Conclusions: Subclinical hypothyroidism is significantly associated with IAC. Hyper-low-density lipoproteinemia, an inflammatory lipoproteinemia, is involved in IAC accompanied by subclinical hypothyroidism., (Copyright © 2022 Journal of Shoulder and Elbow Surgery Board of Trustees.

Study Design: Cross-sectional INTRODUCTION: Globally, diabetes is a leading cause of disability with an increased prevalence rate in the past three decades. Chronic diabetes has been shown to affect collagenous tissue which often leads to subsequent musculoskeletal complications. Despite increasing prevalence of musculoskeletal disorders, the proportion and distribution of types of upper extremity musculoskeletal disorders resulting in disabilities is poorly understood., Purpose of the Study: This cross-sectional study aims to gather data on the prevalence, proportion and distribution of upper extremity musculoskeletal disorders among individuals with Type 2 Diabetes Mellitus. Further, this study examines the relationship between common upper extremity disorders and the resulting disability among individuals with Type 2 Diabetes Mellitus., Methods: 170 individuals diagnosed with Type 2 Diabetes Mellitus were recruited at a tertiary care hospital. Routine upper extremity assessments were performed to identify the presence of Frozen Shoulder (FS), Limited Joint Mobility (LJM), Trigger Finger, Carpal Tunnel Syndrome (CTS), and Dupuytren's Contracture. Disability was measured using the Disabilities of arm, shoulder, and hand (DASH) questionnaire. Descriptive statistics, one-way analysis of variance, Tukey's test, and Pearson's test were used to examine the prevalence, proportion and distribution of musculoskeletal disorders and disabilities among individuals with type 2 Diabetes Mellitus., Results: 83(48.9%) participants had one or a combination of multiple musculoskeletal disorders of the upper extremity. The proportion of LJM, FS, CTS, Trigger Finger, and Dupuytren's Contracture were n = 46(27.1%); n = 43(25.3%); n = 16(9.4%); n = 8(4.7%); n = 5(2.9%) respectively. Disability scores on the DASH were 25.8 ± 14.5, 10.3 ± 11.9, and 10.6 ± 10.4 respectively for individuals with FS, LJM and Trigger Finger. DASH scores were highest in individuals with both CTS and FS, 29.8 ± 19.3. Duration of diabetes was significantly associated (r = 0 .19; P < .01) with the disability scores on DASH., Conclusion: The prevalence of musculoskeletal disorders in people with type 2 Diabetes mellitus remains high despite advances in medical management over the last two decades. The overall prevalence of hand disorders (LJM, CTS, Dupuytren's contracture, Trigger Finger) was higher than shoulder disorders (FS), e.g. frozen shoulder. People with a diabetes that had a diagnosed upper extremity conditon had more upper extremity disability, than those with diabetes but no diagnosed hand condition, Disability was highest for frozen shoulder and lowest for Dupuytren's diagnoses. Carpal tunnel syndrome was the most disabling hand condition. People with diabetes should be screened for upper extremity diagnoses that could limit their function. Poeple with disability resulting from hand disorders was lower than the shoulder disorders. A combination of hand and shoulder disorders resulted in greater disability., (Copyright © 2021.

Objectives: Iliopsoas bursitis (IB) is a relatively rare condition that is associated with hip diseases. It can cause neurological symptoms and swelling of the lower extremities by compressing the femoral nerve and vessels. The aim of this study is to examine the prevalence of IB in patients with end-stage hip osteoarthritis., Methods: A total of 544 patients underwent total hip arthroplasty between May 2010 and May 2019. All patients were examined using computed tomography (CT) to perform preoperative planning. We reviewed the CT images and examined the prevalence and size of IB. These lesions were divided into three types based on their shape (round type, oval type, and heart-shaped type)., Results: Of the 544 patients, IB was found in 37 patients. We observed the round type in 4 patients, the oval type in 31 patients, and the heart-shaped type in 2 patients. Two patients showed severe swelling in the legs and had a blood circulatory disorder of the legs. Both cases were heart-shaped bursitis., Conclusion: Symptomatic IB was observed in two cases, both of which had a heart shape surrounding the iliopsoas tendon and femoral neurovascular bundle. Although symptomatic IB is a rare condition, special attention is required for heart-shaped IB., (© Japan College of Rheumatology 2021. Published by Oxford University Press. All rights reserved.

BACKGROUND Shoulder injury related to vaccine administration (SIRVA) occurs when an intramuscular deltoid injection is administered into the shoulder joint. This observational study describes clinical features in 16 patients with SIRVA following Coronavirus 2019 (COVID-19) vaccination who presented to chiropractic, orthopedic, and physiotherapy clinics in Hong Kong between January 1, 2021, and January 1, 2022. MATERIAL AND METHODS Adults age ≥18 with new-onset shoulder pain and imaging-confirmed shoulder pathology were retrospectively identified from 35 clinics. Patient demographics and clinical and vaccination details were extracted from the electronic medical record. Shoulder injury was determined by correlating clinical and imaging features. RESULTS Of 730 patients with shoulder pain, 16 SIRVA cases (mean age, 49±10 years, 75% female) were identified; (12/16, 75%) of patients received the Pfizer-BioNTech vaccine while (4/16, 25%) received Sinovac-CoronaVac. The most common diagnosis was adhesive capsulitis (10/16, 63%), followed by bursitis (3/16, 19%) and supraspinatus tear (3/16, 19%). Mean symptom onset was 3.5±2.5 days post-vaccination, and always occurred after the 2nd or 3rd vaccination, involving reduced shoulder range of motion (ROM). Mean baseline pain was 8.1±1 (out of 10). All patients received conservative care (eg, exercise, manual therapies). At 3-month follow-up, mean pain reduced to 2.4±1.4; all patients had normal shoulder ROM. CONCLUSIONS In the past 2 years, millions of intramuscular COVID-19 vaccinations have been administered. It is important that clinicians are aware of SIRVA as a cause of new symptoms of shoulder injury and should ask the patient about recent vaccinations, including for COVID-19.

Aims: To examine the association of frozen shoulder (FS) with demographic and diabetes-related outcomes in individuals with type 1 (T1D) or type 2 (T2D) diabetes aged ≥30 years., Materials and Methods: Multivariable logistic regression models, adjusted for demographics were used to calculate the proportion of FS in association with age, gender, diabetes duration, body mass index (BMI), haemoglobin A1C (HbA1c) and diabetes treatment., Results: The unadjusted percentage of FS was higher in T1D compared to T2D (0.22% vs. 0.06%). In T1D, adjusted regression models revealed higher prevalence of FS in women than men (0.26 [0.20-0.34] % vs. 0.15 [0.11-0.21] %, p =0.010). No significant relationship of age and BMI with FS was found in both diabetes types. Longer diabetes duration was associated with a higher proportion of FS in T1D (p <0.001) and T2D ( p =0.004). In T1D, HbA1c >7% was related to a higher proportion of FS compared to HbA1c ≤7% (0.25 [0.19-0.32] vs. 0.12 [0.08-0.20] %, p =0.007), while an inverse relationship was found in T2D (HbA1c ≤7%: 0.08 [0.07-0.10] vs. HbA1c >7%: 0.05 [0.04-0.06] %, p =0.001)., Conclusions: Different associations of FS with gender and HbA1c were observed for T1D and T2D; however, longer diabetes duration increases the risk for FS independent of diabetes type. Musculoskeletal diseases are still underreported in individuals with diabetes and awareness should be raised for FS as a specific diabetes complication., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Purpose: The purpose of this study was to determine imaging features of reactive bursitis secondary to osteochondroma., Materials and Methods: Fourteen patients with reactive bursitis secondary to osteochondroma were retrospectively reviewed., Results: The 14 patients were 11 males and 3 females ranging in age from 18 to 67 years (mean, 33.6 years). The locations were as follows: scapula (n = 2), lesser trochanter (n = 6), greater trochanter (n = 1), distal femur (n = 2), distal fibula (n = 1), iliac bone (n = 2). On CT, six bursae were hypodense and 1 was isodense compared to muscle. All bursae had a thickened wall, 6 contained multiple villous projections and septa. Five bursae contained a few calcifications. On enhanced CT, the bursa displayed mild enhancement of the wall, villous projections, and septa. On MRI, one bursa was hypointense, three were hyperintense, and 5 were isointense relative to muscles on T1-weighted images. All bursae were hyperintense relative to muscles on T2-weighted images. All bursae had a thickened wall, eight contained multiple villous projections and septa. In five bursae, a few fatty villous projections can be seen within the bursa. On enhanced MRI, all bursae displayed avid enhancement of the bursal wall, villous projections, and septa., Conclusions: Reactive bursitis secondary to osteochondroma most often occurred in young male adults. The most common involved site is lesser trochanter. The imaging features is that of an irregular, thick-walled fluid-filled bursa overlying an osteochondroma that containing multiple villous projections and septa. Calcification and/or lipoma arborescens may be developed within the bursa. On contrast-enhanced images, the bursa shows enhancement of the bursal wall, villous projections and septa., (© 2022.

Background: Trochanteric bursitis or greater trochanteric pain syndrome is a common disorder and frequent cause of lateral hip pain. It can lead to severe functional impairment with increase morbidity and poor quality of life.The purpose of the current study was to identify and evaluate relationship between health-related factors, as prognostic indicators, and clinical outcomes., Methods: A single-centre, prospective study was conducted and 60 patients (62 hips) were included with a minimum 12 months of follow-up. Clinical outcomes were evaluated using Hip Outcome Scale, Single Assessment Numeric Evaluation and Visual Analogue Scale. Radiological assessments and health-related factors were documented in an attempt to understand their validity as predictors of clinical outcomes. Complications and recurrence rates were also analyzed., Results: Univariate model revealed that an increased BMI ( p  = 0.001; OR = 1.05; 95% CI, 1.02-1.07); number of previous corticosteroid infiltrations ( p  = 0.001; OR = 1.28, 95% CI, 1.11-1.48); longer time from symptom onset to surgery ( p  = 0.001; OR = 1.19; 95% CI, 1.12-1.28); smoker status ( p  = 0.001; OR 11.2; 95% CI, 3.30-44.2); and the presence of prior lumbosacral fusion (LSF) ( p  = 0.001; OR 13.8; 95% CI, 2.96-101); were prognostic factors predisposing for poor clinical outcomes.Among prognostic health-related factors were medical comorbidities such as emotional distress ( p <  0.001; OR 26.1; 95% CI, 5.71-192); fibromyalgia ( p  = 0.026; OR 3.56; 95% CI, 1.16-11.7); and hyporthyroidism ( p  = 0.005, OR = 6.55, 95% CI, 1.73-28.7)., Conclusions: Better overall physical function was predicted by lower number of corticosteroid infiltrations, shorter time span from symptom onset to surgery, non-smoker status and the absence of prior lumbosacral fusion. Obesity, smoking, the presence of emotional distress, fibromyalgia and hypothyroidism seem to increase the risk of poor clinical outcomes. A proper selection and/or correction of modifiable prognostic factors could reduce the incidence of endoscopic treatment failure and, as a consequence, improve patient outcomes and quality of life. However, future efforts should focus on experimental and randomised studies to fully determine these associations.

Musculoskeletal mimics of cervical radiculopathy will be explored in this AANEM monograph. A review of the literature and textbooks was conducted. Musculoskeletal cervical radiculopathy mimics include: (1) head/neck pain, such as neck tension, cervicogenic headache, and temporomandibular disorder; (2) referred pain from shoulder pathology, such as rotator cuff tears/impingement; (3) elbow region abnormalities, including medial/lateral epicondylitis; (4) wrist/hand conditions, such as DeQuervain's tenosynovitis and intersection syndrome; (5) muscle connective tissue disorders, including myofascial trigger points; (6) conditions that have decreased range of motion, including frozen shoulder and rounded shoulders with tight pectoral/scalene muscles; (7) conditions with joint hyperlaxity and instability, as seen in post-stroke shoulder subluxation; (8) vascular conditions, such as thoracic outlet syndrome; and (9) autonomic controlled soft tissue changes associated with complex regional pain syndrome. Formulating a differential diagnosis and recognizing mimics of cervical radiculopathy can decrease the time between symptom onset and diagnosis/treatment plan., (Copyright © 2022 by the American Association of Neuromuscular & Electrodiagnostic Medicine, Inc.

Shoulder injury related to vaccine administration (SIRVA) is a term given to describe shoulder pain and dysfunction arising within 48 hours after vaccine administration and lasting for more than one week. While SIRVA is most commonly seen after influenza and tetanus vaccines, there have been a few recent case reports describing SIRVA-like symptoms after COVID-19 vaccine administration. Two patients presented to the shoulder surgeon's practice center with complaints of shoulder stiffness and pain following the COVID-19 vaccine. The first patient was a 33-year-old man; he presented within 2 days of onset of the pain and 14 days from the vaccine date. He had a complete restriction of shoulder motion (0° flexion, and no external or internal rotation) at presentation. This patient was treated with non-steroidal anti-inflammatory drugs (NSAID) and rested in a sling for a week. The second patient was a 53-year-old woman; she presented with a 6-week duration of mild restriction of active shoulder motion and shoulder pain. Her magnetic resonance imaging (MRI) revealed the presence of subacromial-subdeltoid bursitis. She was treated with subacromial steroid injection and range of motion shoulder exercises. Both patients recovered a near-normal range of motion recovery within a month, and their pain improved significantly. The main lessons from this case report were: (1) patients presenting with a recent increase in pain and acute loss of shoulder movements after vaccination may be managed conservatively with rest and NSAID medications and (2) in case of a subacromial-subdeltoid bursitis in the MRI, subacromial injection of steroid may provide good pain relief., (Copyright ©2022, Yale Journal of Biology and Medicine.)
