Medial clavicle fractures and injuries to the sternoclavicular joint are rare injuries but can have life-threatening consequences. There are no standardized treatment algorithms or guidelines for the diagnostics and treatment. This article provides an overview of the individual topographies as well as the conservative and surgical treatment strategies.Conservative treatment is preferred for medial clavicle fractures. The indications for surgical treatment are variable but this is frequently carried out if there is a fracture displacement > 1 cm or 1 shaft width and high functional demands. In the case of accompanying injuries to neurovascular structures, an open fracture or the threat of perforation of the skin, surgical treatment is mandatory. Open reduction and internal fixation using (locking) plates is currently the preferred form of treatment.In the case of posterior dislocation of the sternoclavicular joint, an immediate closed reduction must be attempted with the patient under analgosedation and with emergency treatment on standby. This temporal urgency does not exist for anterior and superior dislocations. Surgical treatment is indicated in cases of unsuccessful reduction, persistent symptomatic instability or injuries of the neurovascular bundle. From a multitude of treatment options, arthrodesis with suture cerclage has shown good results. Tendon grafts as well as special hook plates are increasingly being used due to better biomechanical qualities. The surgical treatment of combined injuries is determined by the individual injury pattern.Despite the variety of treatment strategies, the long-term outcome has consistently been positively described., (© 2024.

To examine the clinical effect of different conservative therapies (Glisson traction, soft and rigid cervical collar) in the treatment of children with acute atlantoaxial rotatory subluxation. One hundred and forty-four children with acute atlantoaxial rotatory subluxation treated conservatively at our hospital from June 2017 to June 2022 were retrospectively analyzed. The children were divided into three groups consisting of patients treated with Glisson traction (n = 37), patients treated with soft cervical collar (n = 55), and patients treated with rigid cervical collar (n = 52). Clinical and functional results were compared among the three groups. Success outcomes were achieved at the end of treatment in the Glisson traction group (94.59%, 35/37), soft cervical collar group (83.64%, 46/55), and rigid cervical collar group (92.31%, 48/52). There was no significant difference between the success rates among the three groups (P > 0.05). At the last follow-up, the overall scores based on our scoring scale for the Glisson traction, soft cervical collar and rigid cervical collar groups were 95.95 ± 6.11 (range: 75-100), 94.64 ± 6.30 (range: 75-100) and 95.00 ± 6.02 (range: 70-100), respectively. There was no significant difference in the overall scores among the three groups (P > 0.05). All three conservative therapies for the treatment of acute atlantoaxial rotatory subluxation can attain a good clinical outcome. Treatment using a cervical collar should be given priority as it does not require the child to be hospitalized. Rigid cervical collar provides good immobilization and can possibly lead to better clinical outcomes compared to a soft cervical collar., (© 2024. The Author(s).)

Background: This case series presents five cases of adult atlantoaxial rotatory subluxation (AARS) following traumatic events, focusing on treatment strategies and long-term outcomes., Case Presentation: This paper includes four Iranian male patients and one Iranian female patient with ages ranging from 25 to 46 years old. Each case involved unique presentations and management approaches. Initial conservative treatments, including skull traction and orthoses, were attempted, but surgical intervention became necessary due to inadequate response. Surgical fixation significantly improved functional status and alleviated symptoms in all patients, leading to long-term relief. Radiological assessments demonstrated successful outcomes post-surgery., Conclusions: This study underscores the importance of considering both conservative and surgical options in managing adult atlantoaxial rotatory subluxation to achieve optimal outcomes., (© 2024.

The current research paper was designed to assess the impact of an intra-articular injection of injectable platelet-rich fibrin (I-PRF) following arthrocentesis and the use of an anterior repositioning splint (ARS) as a proposed treatment approach for addressing symptomatic internal derangement of the temporomandibular joint (TMJ). This study comprised thirty patients who presented with bilateral disc displacement without reduction. The patients were evenly distributed into two groups: Group I underwent treatment involving ARS and arthrocentesis alone, while Group II underwent treatment with ARS, arthrocentesis, and the injection of I-PRF. Clinical assessment of all patients was done postoperatively in the following intervals; first week, first month, third month, and six months for maximum mouth opening (MMO), right and left lateral excursion, and pain score. Magnetic resonance imaging (MRI) assessment for all joints was done at the sixth month postoperatively. Both groups demonstrated improvement in MMO, lateral excursion, and pain. Significant statistical differences were observed in the mean values of MMO and Visual Analogue Scale (VAS), favouring the I-PRF group. MRI postoperatively showed no significant changes in disk position or morphology at the end of the sixth month. Administering an intra-articular I-PRF injection subsequent to arthrocentesis demonstrates effectiveness as a treatment approach for alleviating the signs and symptoms associated with internal derangement of the TMJ., (Copyright © 2024 The British Association of Oral and Maxillofacial Surgeons.

Temporomandibular joint dislocation is a common challenge in dental care, but it can be promptly addressed through manual realignment, making it standard procedure in the realm of oral health. Nonetheless, effectively preventing and treating chronic protracted mandibular dislocation (CPMD), characterized by prolonged dislocation, remains a significant challenge. Hence, a retrospective analysis was conducted on the clinical data of 10 patients diagnosed with chronic protracted mandibular dislocation (CPMD), encompassing diagnosis, treatment, and prognosis details. CPMD tends to be more prevalent among the elderly population, with an average age of 67.2±11.9 years and a male-to-female ratio of 1:9. All diagnosed patients presented with bilateral anterior dislocation, each requiring diverse pre-treatment approaches. The most significant risk factor contributing to CPMD was unconsciousness resulting from nervous system injury, which delayed the perception of symptoms associated with temporomandibular joint dislocation. 90% of CPMD patients experienced successful treatment through manual reduction, while a refractory CPMD cohort, resistant to manual reduction, necessitated surgical intervention for resolution. All patients underwent treatment involving elastic intermaxillary traction, which served as the primary means of achieving reduction. Subsequent analysis of CT data revealed that condylar displacement beyond the zygomatic arch served as an indication for surgical reduction. Consequently, manual reduction under general anesthesia combined with elastic intermaxillary traction proved effective for managing CPMD cases. However, cases displaying excessive vertical displacement beyond the zygomatic arch should be considered for surgical intervention based on CT findings., (© 2024. The Author(s).)

Objectives: Current studies on the treatment of adolescent patients with disc displacement without reduction (DDWOR) are limited by short follow-up periods and small sample sizes, and there are few comparative studies on the efficacy of conservative treatment with and without disc reduction for acute DDWOR. This study compared the therapeutic effects of two conservative treatment methods: physical therapy alone and physical therapy combined with non-surgical manual disc reduction and anterior repositioning splints (ARS), in adolescent patients with acute DDWOR., Materials and Methods: This retrospective study included adolescent patients with DDWOR who underwent physical therapy at the Temporomandibular Joint Rehabilitation Department of the Shanghai Ninth People's Hospital from January 2018 to December 2021. Patient assessment data were collected before and after treatment. Patients were followed up through telephone and online questionnaires from March to August 2023., Results: The results indicate that compared to physical therapy alone, the combination of physical therapy and non-surgical manual disc reduction with ARS showed better short-term efficacy, improved mouth opening, and better long-term pain control. Also, it may be effective in preventing degenerative joint disease., Conclusions: This combination therapy is recommended for clinical application in adolescent patients with acute DDWOR., Clinical Relevance: The present research demonstrates the superior efficacy of physical therapy and non-surgical manual disc reduction combined with anterior repositioning splint in adolescent patients with acute DDWOR., (© 2024.

Introduction: Temporomandibular disorders (TMD) may include conditions involving the temporomandibular joint and/or masticatory muscles. Approximately 20 % of patients are refractory to first-line therapies. This study aims to evaluate the effects and safety of incobotulinumtoxinA in the treatment of refractory TMD due to disk dislocation., Material and Methods: A quasi-experimental one-arm prospective study was conducted. Target population included individuals with a diagnosis of TMD due to disk dislocation. Patients were treated with electromyography or ultrasound guided injection of incobotulinumtoxinA in the masticatory muscles (20 U into each masseter and pterygoideus lateralis). Pain was assessed using the pain numerical rating scale, maximum unassisted mouth opening was measured in mm, and adverse events were registered at baseline, week 4, week 12 and week 24 post-treatment. Statistical analysis used the Wilcoxon test for the comparison of paired samples and the Mann-Whitney U test for independent samples, considering a p-value ≤ 0.05 as significant., Results: 51 patients with 75 painful temporomandibular joints due to disk dislocation (38 with reduction and 37 without) were included. A significant reduction in pain from a pre-treatment mean of 6.08/10 to a post-treatment mean of 2.04/10 (week 4), 3.18/10 (week 12), and 3.65/10 (week 24) was observed (p < 0.001). A significant decrease in maximum unassisted mouth opening from a pre-treatment mean of 36.45 mm to a post-treatment mean of 32.29 mm at week 4 was observed (p < 0.001)., Discussion: Botulinum toxin injection of the masticatory muscles is safe and seems equally effective in reducing pain in patients with refractory TMD due to disk dislocation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Lisfranc injuries are rare but severe injuries of the foot. They range from ligament sprain to complex fracture dislocations. Etiologically, a distinction is made between indirect and direct force and between high-energy and low-energy trauma. Inadequate diagnostics (injuries overlooked or misinterpreted) can lead to painful posttraumatic osteoarthritis, chronic instability and deformity of the foot. A fracture, malalignment and unclear findings in conventional radiological diagnostics necessitate computed tomography imaging including 3D reconstruction. Lisfranc injuries are often associated with accompanying pathologies of the foot that also need to be addressed. Only stable non-displaced fractures can be treated conservatively. Depending on the injury pattern, surgical treatment is performed percutaneously, minimally invasive or open. The prognosis following Lisfranc injury is determined by the severity of damage and the quality of reconstruction., (© 2024.

Disc displacement without reduction (DDwoR) can cause pain and limitations in mouth opening, with a significant impact on function. The optimal management strategy for DDwoR is unclear. Treatments include conservative management such as mandibular manipulation, occlusal splints, and patient education/self-management, as well as arthrocentesis, which is a minimally invasive procedure. The aim of this systematic review and meta-analysis was to ascertain whether there is a role for arthrocentesis in the management of DDwoR. Studies analysing the outcomes pain and maximum mouth opening (MMO) in patients with DDwoR treated by arthrocentesis or occlusal coverage devices were eligible for inclusion. Following a database search, six studies with a total of 343 participants were found to be eligible for analysis (three prospective observational studies, one retrospective observational study, one non-randomized single-blind clinical trial, and one unblinded randomized clinical trial). When compared to occlusal coverage splints, arthrocentesis demonstrated a slight improvement in pain, although this was statistically non-significant (standardized mean difference (SMD) -0.50, 95% confidence interval (CI) -1.04 to 0.05, P = 0.07; I 2 = 81%), and a significant improvement in MMO (SMD 0.79 mm, 95% CI 0.24-1.35 mm, P = 0.005; I 2 = 79%). However, due to the significant heterogeneity between studies and the high risk of bias, along with the paucity of double-blind randomized controlled clinical trials, definitive conclusions cannot be drawn for this clinical question., (Copyright © 2024 International Association of Oral and Maxillofacial Surgeons.

Background: Ultrasound-guided supraclavicular block (UGSCB) is an emerging technique gaining interest amongst emergency physicians that provides regional anaesthesia to the upper limb to tolerate painful procedures. It offers an alternative to the more traditional technique of a Bier block (BB). However, the effectiveness or safety of UGSCB when performed in the emergency department (ED) is unclear., Methods: SUPERB (SUPraclavicular block for Emergency Reduction versus Bier block) is a prospective open-label non-inferiority randomised controlled trial comparing the effectiveness of UGSCB versus BB for closed reduction of upper limb fractures and/or dislocations. Adult patients presenting with upper limb fracture and/or dislocation requiring closed reduction in ED were randomised to either UGSCB or BB. Once regional anaesthesia is obtained, closed reduction of the injured part was performed and immobilised. The primary outcome is maximal pain experienced during closed reduction measured via a visual analogue scale (VAS). Secondary outcomes include post-reduction pain, patient satisfaction, total opioid requirement in ED, ED length of stay, adverse events and regional anaesthesia failure., Results: Primary outcome analysis will be performed using both the intention-to-treat and per-protocol populations. The between-group difference in maximum pain intensity will be assessed using linear regression modelling with trial group allocation (UGSCB vs BB) included as a main affect. A pre-specified non-inferiority margin of 20 mm on the VAS scale will be used to establish non-inferiority of UGSCB compared to BB., Conclusion: SUPERB is the first randomised controlled trial to investigate the effectiveness and safety of UGSCB in the ED. The trial has the potential to demonstrate that UGSCB is an alternative safe and effective option for the management of upper extremity emergencies in the ED., (© 2024. The Author(s).)

Background: The clinical diagnosis of atlantoaxial joint subluxation (AJS) in traditional Chinese medicine (TCM) is characterized by an unequal distance between the lateral mass of the atlas and the odontoid process on imaging, resulting in neck pain accompanied by symptoms such as dizziness, headache, and limited cervical mobility. In Shanghai, Shi cervical rotational manipulation (SCRM) is a commonly employed TCM manual therapy for treating this condition. Nevertheless, there is a lack of evidence-based medical information regarding the clinical efficacy and safety of this technique., Objective: The principal aim of this study is to evaluate the efficacy and safety of SCRM in patients diagnosed with AJS., Methods: This study is a prospective randomized controlled clinical trial that will be conducted at a single center and that has a follow-up period of 24 weeks. A total of 96 patients diagnosed with AJS will be recruited from outpatient and inpatient clinics at Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine. These patients will be randomly assigned to either the experimental group (SCRM) or the comparison group (basic cervical manipulation [BCM]). Treatment sessions consisting of SCRM or BCM will be administered twice a week for a duration of 4 weeks. Clinical monitoring indicators include the presence or absence of clinical symptoms as recorded on a symptom recording form, cervical imaging examination findings using cervical computed tomography, degree of neck pain measured by a visual analog scale (VAS), cervical range of motion assessed through cervical mobility measurement, degree of vertigo evaluated using the Vertigo Symptoms Scale-Chinese Version (VSS-C), and adverse events that may occur during the follow-up period. The time points for data collection and follow-up are baseline and postintervention (weeks 4, 8, 12, 16, 20, and 24)., Results: This paper presents an overview of the reasoning and structure of a prospective randomized controlled trial with the objective of investigating the clinical efficacy and safety of SCRM in patients with AJS by assessing improvements in clinical symptoms, neck pain severity, and vertigo severity and evaluating changes in cervical imaging findings. Recruitment was started in March 2023. By the end of May 2024, 76 patients were included in this project. The last follow-up data are predicted to be collected by the end of February 2025., Conclusions: This investigation will yield dependable evidence regarding the efficacy and safety of SCRM in patients with AJS., Trial Registration: Chinese Clinical Trial Registry ChiCTR2300068510; https://www.chictr.org.cn/showprojEN.html?proj=186883., International Registered Report Identifier (irrid): DERR1-10.2196/57865., (©Deng Zhen, Shang Haibin, Ai Youli, Yuan Weian, Wang Huihao, Zhan Hongsheng, Li Guozhong, Ding Ren, Shen Zhibi.

Objective: to compare the combined effect of Prolotherapy and Deep Dry Needling (DDN) versus DDN effect on relieving the symptoms of Temporomandibular joint (TMJ) anterior disc displacement., Patients and Methods: The clinical trial randomly allocated forty patients. The (control group) patients received four intraarticular and masseteric DDN sessions, while the (study group) patients were subjected to the exact technique followed by Prolosolution injection. The baseline preoperative measurements included Maximal interincisal opening (MIO), auscultation of the presence of clicking, and Visual Analogue Scale (VAS), which were repeated for postoperative measurements after one, two, five, and eight months., Results: By the end of the study, all patients expressed apparent improvement in pain MIO and clicking. The inter- and intragroup comparison revealed that the pain score values of the control group after five and eight months were significantly higher than those of the study group. The study group demonstrated more significant MIO calibration than the control group, with insignificant differences between both groups regarding the presence of clicking at any time interval. The associations between clicking and VAS values, between clicking and MIO, and between VAS values and increased MIO were positive in the test group and negative in the control group., Conclusions: Dextrose Prolotherapy and DDN were beneficial. However, Prolotherapy demonstrated more significant, sustained, and correlated long-term alleviation of symptoms and increased MIO., Clinical Relevance: The study assesses the sole effect of dextrose prolotherapy on relieving the signs of TMJ anterior disc displacement apart from the impact of the penetrating needle., Clinical Trial Registration: The study was registered on www., Clinicaltrials: gov (#: NCT05821985) by Ahmed Nagi Alghandour., (© 2024.

Introduction: Anterior displacement of the temporomandibular joint (TMJ) disc is a disorder in which the articular disc is dislocated from its correct position relative to the mandibular condyle and mandibular fossa. Traditionally, the initial treatment of disc displacements involves various conservative measures, including the use of a stabilizing interocclusal splint. However, in cases where there is associated limited mouth opening, as in the case of anterior disc displacement with reduction and intermittent block (ADDwRIB), and anterior disc displacement without reduction (ADDw/oR), arthrocentesis has been suggested as another modality of initial treatment due to its faster effect in preventing disease progression to a more advanced stage, as well as reducing the chances of pain chronification and central sensitization., Objectives: This study aimed to analyze whether there is a preponderance in efficacy between treatments with a stabilizing interocclusal splint or arthrocentesis in these patients., Methods: A randomized, prospective, longitudinal clinical trial was conducted. The sample was obtained by convenience, between June 2021 and January 2023. Twenty-four patients with diagnoses of ADDwRIB and ADDw/oR were included. The diagnosis and clinical evaluations followed the DC/TMD criteria, and TMJ MRI was performed. Patients were randomly allocated to 2 treatment groups. Group 1 (n = 13): stabilizing interocclusal splint. Group 2 (n = 11): arthrocentesis. Patients were evaluated after 1, 2, 3, and 6 months for clinical parameters of pain, functionality, and psychosocial status., Results: Both treatments were effective in reducing pain levels, with no statistically significant differences. Group 1 showed significantly greater mouth-opening levels compared to Group 2 (P = .041)., Conclusion: Both groups showed significant improvements in various parameters evaluated throughout the study, indicating they are equally effective in pain control and most functional and quality of life parameters. However, the stabilizing interocclusal splint treatment was superior in restoring mouth opening., Competing Interests: Declarations of Interests None., (Copyright © 2024 Elsevier Inc.

Grisel's syndrome is a non-traumatic atlantoaxial (C1-C2) subluxation and one of the causes of torticollis in children. The subluxation occurs in the context of an infection in the ENT ("Ear Nose and Throat") region or following surgery. Diagnosis is based on clinical examination and radiological assessment. Treatment is typically medical and conservative, with surgical interventions reserved for recurrences and late presentations. We discuss here two cases of C1-C2 subluxation. The first case involves a 10-year-old child with subluxation following a rhinopharyngitis. This presentation is the classical manifestation of Grisel's syndrome. Prompt management led to correction of the subluxation using medical treatment and a soft Philadelphia collar. The second case involves a 34-year-old adult who developed posterior headaches after sphenoidotomy surgery. Grisel's syndrome is less common in adults, leading to clinical challenges and delayed diagnosis (> 1 month). Reduction combined with a halo vest treatment failed, and the patient required cervical arthrodesis.

Background: Fractures of the lateral condyle of the humerus in children are articular fractures with difficult diagnostics due to the incompletely ossified elbow joint. The aim of this study was to evaluate the method of treatment at initial presentation and to analyze the frequency of subsequent displacement during follow-up., Material and Method: Retrospective analysis of the frequency of primary fracture dislocation and subsequent displacement of fractures of the lateral condyle of the humerus in children under 16 years of age between 2004 and 2021. Conventional radiographs in two planes at the time of the accident and in the follow-up after 5-7 days were evaluated., Results: A total of 285 fractures of the lateral condyle of the humerus were evaluated. The average age was 5.3 years. Of the fractures 109 (38.3%) were directly surgically treated in cases of primary displacement and 176 fractures (61.7%) were not primarily displaced and were initially treated conservatively. During follow-up, subsequent displacement was evident in 46 fractures (26.1%). A total of 130 fractures (45.6%) were treated conservatively and 155 fractures (54.4%) were treated surgically using open joint visualization and screw osteosynthesis or K‑wire osteosynthesis., Conclusion: Fractures of the lateral condyle of the humerus occur more frequently in a certain age group and require targeted radiological diagnostics. Nondisplaced fractures can be treated conservatively but essential radiological follow-up shows a high number of subsequent displacements, so that open surgical stabilization is often necessary., (© 2024.

There is currently no consensus on the best treatment for painful temporomandibular disc displacement without reduction (DDwoR), and no network meta-analysis (NMA) of randomized clinical trials (RCTs) comparing all types of treatments for this condition has been conducted. The objective of this study was to compare and rank all treatments for DDwoR, including conservative treatments, occlusal splints, low-level laser therapy (LLLT), arthrocentesis (Arthro) alone, Arthro plus intra-articular injection (IAI) of platelet-rich plasma (PRP), Arthro plus IAI of hyaluronic acid (HA), Arthro with exercises, Arthro plus occlusal splints, and manipulative therapy. Outcome variables were pain intensity on a visual analogue scale (VAS) and maximum mouth opening (MMO, mm). The mean difference with 95% confidence interval was estimated using Stata software. The GRADE system was used to assess the certainty of the evidence. A total of 742 patients from 16 RCTs were included in the NMA. Both direct meta-analysis and NMA showed that Arthro with IAI of co-adjuvants provided better pain reduction in the short term (≤3 months) than Arthro alone. However, the quality of the evidence was very low. In the intermediate term, Arthro alone or combined with co-adjuvants provided better pain reduction than conservative treatment, but with low-quality evidence. Conservative treatment significantly increased MMO in the short term compared to other treatments. In conclusion, the results of this NMA suggest that arthrocentesis with intra-articular injection of adjuvant medications may be superior to conservative treatments in reducing pain intensity at long-term follow-up, while no significant differences were found for the MMO outcome. However, the quality of evidence was generally low to very low, and further RCTs are needed to confirm these findings., (Copyright © 2024 International Association of Oral and Maxillofacial Surgeons.

Purpose: The study aimed to report the results of the Delphi survey conducted by the Shoulder, Elbow Society India (SESI), to achieve consensus on ambiguous topics in managing type III acromioclavicular joint (ACJ) dislocations., Methods: This study was based on responses from the Shoulder Elbow Society India (SESI) panel of peer-selected twenty senior surgeons practicing shoulder orthopedics. They participated in two rounds of the survey to obtain consensus on several topics pertaining to the management of type III ACJ dislocations. Consensus was achieved when at least 70 % of the panel members selected at least a 4-point on a 5-point Likert scale., Results: Our Delphi survey reached a consensus on seven topics of ambiguity. An anteroposterior and axillary view of the shoulder without any traction or weight in hand is sufficient in the setting of a suspected type III ACJ dislocation. Magnetic resonance imaging (MRI) is not routinely indicated in type III ACJ dislocation. Either cross-arm adduction X-rays or clinical examination may be used to distinguish between ISAKOS (International Society of Arthroscopy, Knee surgery and Orthopaedics Sports medicine) IIIA and B classification of ACJ to identify stable and unstable injuries. Conservative treatment can be offered to patients who have stable injuries and who are not high-demand individuals in acute type III ACJ dislocations. In conservative management of type III ACJ dislocation, a two-week sling suffices. Jones strapping has no clear advantage over a shoulder sling. Coracoclavicular reconstruction with an autograft is an acceptable way to treat symptomatic, chronic grade III ACJ dislocation., Conclusion: The survey helped achieve consensus on several controversial issues related to type III ACJ dislocations. However, there remains ambiguity on the definition of chronicity of such dislocations, the necessity of bilateral Zanca views, and the duration of conservative trial before switching to a surgical line of management., Competing Interests: Declaration of competing interest None of the authors have any conflict of interest related to the subject of the present study., (Copyright © 2024 Elsevier Ltd.

Abstract: Radial head subluxation, or nursemaid's elbow, is a common orthopedic complaint in children and often is the result of a pulling injury to the affected arm. Although this injury largely is a clinical diagnosis, different imaging modalities may be used to identify it and confirm successful reduction. Multiple manipulative techniques can be used to treat this injury and methods are generally specific to clinician preference. This article reviews the causes, evaluation, and management of radial head subluxation., (Copyright © 2024 American Academy of Physician Associates.)

Introduction: Finger and hand injuries are among the most common musculoskeletal conditions presenting to emergency departments and primary care providers. Many rural and community hospitals may not have immediate access to an orthopedic surgeon on-site. Furthermore, military treatment facilities, both within the continental United States and in austere deployment environments, face similar challenges. Therefore, knowing how to treat basic finger and hand injuries is paramount for patient care., Materials and Methods: The Armed Forces Health Surveillance Branch operates the Defense Medical Surveillance System, a database that serves as the central repository of medical surveillance data for the armed forces. The Defense Medical Surveillance System was queried for ICD-10 codes associated with finger injuries from 2015 to 2019 among active duty service members across the major branches of the military., Results: The most commonly reported finger injuries were open wounds to fingers without damage to nails, metacarpal fractures, phalanx fractures, and finger subluxation/dislocation. Emergency departments were the most commonly reported treatment facility type accounting for 35% of initial finger injuries, followed by 32.2% at orthopedic surgery clinics, 22.2% at family medicine clinics, and 10.8% at urgent care centers., Conclusions: Finger injuries are common in the military setting and presenting directly to an orthopedic surgeon does not appear the norm. Fingertip injuries, fractures within the hand, and finger dislocations can often be managed without the need for a subspecialist. By following simple guidelines with attention to "red flags," primary care providers can manage most of these injuries with short-term follow-up with orthopedics., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.

Objective: To compare the treatment effectiveness of digitized and 3D-printed repositioning splints with that of conventional repositioning splints in the treatment of anterior displacement of the temporomandibular joint disc., Methods: This retrospective study included 96 patients with disc displacement of the anterior temporomandibular joint. They were treated with either digitally designed and 3D-printed repositioning splints or traditional splints and followed up for at least six months. Changes in signs and symptoms such as pain and mouth opening before and after treatment were recorded to evaluate treatment outcomes., Results: During the first month of treatment, both the digitally designed and 3D-printed repositioning splint groups (Group B) and the traditional repositioning splint group (Group A) showed significant increases in mouth opening, with increases of 4.93 ± 3.06 mm and 4.07 ± 4.69 mm, respectively, and there was no significant difference between the two groups. Both groups had a significant reduction in visual analog scale (VAS) pain scores, with Group B showing a greater reduction of 1.946 ± 1.113 compared to 1.488 ± 0.978 in Group A (P < 0.05). By the sixth month, Group B's mouth opening further improved to 38.65 ± 3.22 mm (P < 0.05), while Group A's mouth opening did not significantly improve. Regarding pain, Group A's VAS score decreased by 0.463 ± 0.778 after one month, and Group B's score decreased by 0.455 ± 0.715; both groups showed significant reductions, but there was no significant difference between the two groups., Conclusion: Compared with traditional repositioning splints, digitally designed and 3D-printed repositioning splints are more effective at reducing patient pain and improving mouth opening. 3D-printed repositioning splints are an effective treatment method for temporomandibular joint disc displacement and have significant potential for widespread clinical application., (© 2024.

An internal derangement of the temporomandibular joint is described as a deviation in the position or shape of the joint tissues. Such a change is only functionally manifest if it interferes with smooth movements of the jaw joint. There are a number of internal derangements associated with jaw movements in which popping jaw joint sounds can occur. Examples are an anteriorly or posteriorly displaced disc and hypermobility of the condylar head. Although most internal derangements are harmless and only cause minor discomfort to patients, disc displacements can in some cases develop into a clinical problem, for example when there is a limitation of mouth opening (so-called closed lock) or an inability to close the mouth (so-called open lock). Most patients with these conditions do not require any or only conservative treatment.

Objectives: After the establishment of the virtual pediatric emergency medicine clinic at our institution, we noted that several physicians independently began to instruct caregivers virtually on reducing a radial head subluxation. We thus conducted a case series to investigate the number, success, and follow-ups for the virtual reduction of radial head subluxation., Methods: The electronic medical records at our institution were searched from the inception of the virtual clinic in May 2020 until August 2022 (inclusive), for visits and discharge diagnosis containing the word "elbow" or "arm.", Results: Fourteen charts were retrieved; however, 2 were excluded because they were not a suspected radial head subluxation. A virtual reduction was attempted for eight (66.7%) of the 12 patients. In 6 of 8 patients (75.0%), the reduction was deemed successful, and for 2 patients (25.0%), it was deemed unsuccessful. Of the latter, one was found to have a nondisplaced radial neck fracture. All 4 patients (33.3%) for whom a virtual reduction was not attempted were referred to the emergency department., Conclusions: Virtual video coaching of pulled elbow reduction was completed at our institution with overall good success rate. All the physicians involved noted the essential need and benefits of video conferencing for successfully reducing radial head subluxation. We note that a pediatric population may be more amenable to video-based appointments than other populations due to their caregivers' familiarity with digital technology. Finally, as nonphysician models of healthcare delivery for virtual urgent care visits expand, we propose a checklist based on our experience to ensure patient safety., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Congenital radial head subluxation is relatively rare and may be overlooked due to mild symptoms. The diagnosis mainly relies on imaging and history. Observation is an option for those with insignificant symptoms, while surgical intervention, such as ulnar osteotomy or arthroscopy, is often required when dysfunction exists. A 30-year-old man was admitted with congenital radial head dislocation, which was treated with manipulative repositioning. During follow-up, the patient regained the original mobility of the elbow joint and had no recurrence of dislocation. In conclusion, in adults with congenital dislocation of the radial head, we recommend conservative treatment as a first step.

Atlantoaxial rotatory fixation (AARF) in adults is a rare and clinically challenging condition characterized by a spectrum of etiological factors, predominantly attributed to traumatic and inflammatory pathologies within the craniovertebral region. Trauma is the most frequently identified cause within the adult population, with the first case report published in 1907. This study aims to conduct a systematic review that addresses the clinical presentations and management strategies relating to traumatic atlantoaxial rotatory fixation in adults. A comprehensive search of the PubMed database was executed, adhering to the PRISMA guidelines. The inclusion criteria encompassed case reports and series documenting AARF cases in individuals aged 18 and above, spanning database inception to July 2022. Studies not published in the English language were excluded. A total of 61 articles reporting cases of AARF in the adult population were included in the study. The mean age of affected individuals was 36.1 years (± 15.6), with a distribution of 46% females and 54% males. Predominant mechanisms of injury included motor vehicle accidents and falls, constituting 38% and 22% of cases, respectively. Among the classification systems employed, Fielding and Hawkins type I accounted for the majority at 63%, followed by type II at 10%, and type III at 4%. Conservative management was used for treatment in 65% of acute (65%) cases and 29% of chronic cases. Traumatic AARF is a rare phenomenon in the adult population, is more common in younger adults, and does not often present with neurologic deficits. Patients diagnosed acutely are more likely to be successfully treated with conservative management, while patients diagnosed chronically are less likely to be reduced with conservatively and often require surgical treatment. Surgery should be considered for patients with irreducible dislocations, ligamentous injuries, unstable associated fractures, and persistent pain resistant to conservative management., (© 2024.

Background: Current treatment concepts for simple elbow dislocation involve conservative and surgical approaches. The aim of this systematic review was to identify the superiority of one treatment strategy over the other by a qualitative analysis in adult patients who suffered simple elbow luxation., Study Design: A systematic review in accordance with the PRISMA guidelines and following the suggestions for reporting on qualitative summaries was performed. A literature search was conducted using PubMed and Scopus, including variations and combinations of the following keywords: elbow, radiohumeral, ulnohumeral, radioulnar, luxation, and therapy. Seventeen studies that performed a randomized controlled trial to compare treatment strategies as conservative or surgical procedures were included. Reviews are not selected for further qualitative analysis. The following outcome parameters were compared: range of motion (ROM), Mayo Elbow Performance Score (MEPS), Disabilities of the Arm, Shoulder and Hand outcome measure (Quick-DASH), recurrent instability, pain measured by visual analog scale (VAS) and time to return to work (RW)., Results: Early mobilization after conservative treatment strategies showed improved ROM compared to immobilization for up to 3 weeks after surgery with less extension deficit in the early mobilization group (16° ± 13°. vs. 19.5° ± 3°, p < 0.05), as well as excellent clinical outcome scores. Surgical approaches showed similar results compared to conservative treatment, leading to improved ROM (115 vs. 118 ± 2.8) and MEPS: 95 ± 7 vs. 92 ± 4., Conclusion: Conservative treatment with early functional training of the elbow remains the first-line therapy for simple elbow dislocation. The surgical procedure provides similar outcomes compared to conservative treatment regarding MEPS and ROM for patients with slight initial instability in physical examination and radiographs. People with red flags for persistent instability, such as severe bilateral ligament injuries and moderate to severe instability during initial physical examination, should be considered for a primary surgical approach to prevent recurrent posterolateral and valgus instability. Postoperative early mobilization and early mobilization for conservatively treated patients is beneficial to improve patient outcome and ROM., (© 2024. The Author(s).)

This study aims to investigate the morphological characteristics of the temporomandibular joint (TMJ) in the patients with anterior disc displacement with reduction (ADDwR) and the alterations after occlusal splint treatment. Thirty ADDwR patients and ten asymptomatic subjects were recruited. Thirteen parameters were adopted, along with automatic computation and presentation of the joint space to characterize the TMJ morphologies. Statistical results showed that morphological discrepancies between the patients and the asymptomatic subjects were ubiquitous. The adjustment of condyle position through occlusal splint treatment can result in joint spaces widening and has positive effects on mitigating the conditions of ADDwR.

While rib fractures are common in blunt thoracic trauma, dislocations of the costovertebral joints (CVJs) are extremely rare and typically involve the first, eleventh, or twelfth rib. We report a rare case of dislocation of the left fourth and sixth CVJs in a 36-year-old man who was run over by a car. The rib heads were displaced anteriorly, abutting the aorta. Additional injuries included bilateral hemopneumothoraces, pneumomediastinum, pulmonary contusions, grade 3 splenic injury, left adrenal hematoma, retroperitoneal hematoma, Morel-Lavallée lesions at bilateral hips, and multiple fractures, including at the ribs and pelvis. There was also a fracture of the fourth thoracic vertebral body, which was occult on initial CT, but seen on subsequent CTs. The CVJ dislocations were managed conservatively, without short-term complications. Prompt surgical intervention has been recommended in cases where sharp rib fracture fragments are displaced close to the aorta to prevent fatal aortic injuries. However, there is a literature gap on the management of rib heads that are dislocated against the aorta. Our experience suggests that conservative management may be acceptable in some of these cases. This case report aims to increase radiologists' awareness of CVJ injuries, which are important for thoracic spine stability, and highlights the association between CVJ dislocations and spinal injuries., (© 2023.

The sacroiliac joint is an important part of human life behavior and daily activities. With the increase in people's lives and work pressure and the change of travel mode, the incidence rate of sacroiliac joint subluxation is getting higher and higher. The purpose of this study is to explore the relationship between medical choice, health behavior, and health status of patients with sacroiliac joint subluxation and put forward feasible suggestions for promoting the treatment and rehabilitation of patients. The EuroQoL 5 Dimensions 5 Levels health index survey scale was selected to investigate the health status of patients with sacroiliac joint subluxation. T test and analysis of variance were used for univariate analysis of medical choice and health behavior of patients with sacroiliac subluxation, and ordinary least squares was used for multivariate analysis. The elderly patients with subluxation of sacroiliac joint are in poor health. The health status of patients who chose to seek medical treatment for disease diagnosis and prescription was significantly worse. Patients with subluxation of sacroiliac joint with regular defecation have better health status. Patients who travel by bike or bus have worse health. The health status of those who sit still for more than 1 hour a day is significantly better. The health status of patients with sacroiliac subluxation is closely related to their choice of medical treatment and health behavior. It is suggested that rehabilitation therapy such as acupuncture and manipulation should be selected for intervention. Good health behaviors such as abstinence and regular defecation should be shaped. More attention should be paid to the health status of women at risk., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Arytenoid cartilage dislocation can occur as a complication of tracheal intubation and laryngeal trauma, but its occurrence with indirect video laryngoscopy has not been reported. This paper reports anterior arytenoid dislocation occurring after nasotracheal intubation performed under indirect laryngoscopy using a video laryngoscope (McGRATH MAC; Medtronic). The dislocation is presumed to have resulted from the laryngoscope blade being initially inserted too deeply and applying pressure to the posterior aspect of the left cricoarytenoid joint. This patient's anterior arytenoid dislocation was treated conservatively using speech therapy with resolution occurring approximately 40 days postoperatively. On the 74th day after surgery, fibroscopic examination confirmed recovery and healing of the dislocation. However, other types of arytenoid dislocations and laryngeal injuries may require alternative treatment. Early consultation with an otolaryngologist is recommended if arytenoid dislocation is suspected., (© 2023 by the American Dental Society of Anesthesiology.)

Introduction: Isolated fractures of the iliac wing are a rare injury, usually occurring in high-energy trauma, and are associated with other non-musculoskeletal and soft tissue injuries that could compromise the patient's life. Surgical indications are unclear, and there is limited information on the most frequent fracture patterns., Methods: A descriptive multicenter case series study of isolated fractures of the iliac wing treated surgically in three referral trauma hospitals in Latin America. The different fracture patterns are described, the "iliac ring" concept is proposed, and a classification is made., Results: Twenty-eight patients were included; 24 were male, the median age was 31 years RIQ (24-46), the most frequent trauma mechanism was a traffic accident, and in 14 patients, the ISS >16. The most frequent associated injury was to the appendicular skeleton at another level in 13 patients. In the new classification, according to the number of fragments, 11 patients were classified as type A (1 fragment), ten patients as type B (two fragments), and seven patients as type C (three or more fragments). The most compromised anatomical area was the crest and anterosuperior iliac spines in 26 patients, followed by the fossa and anteroinferior iliac spine in 17 and 8 patients, respectively., Discussion: The patterns of isolated fractures of the iliac wing allow the identification of three types of fractures. Identifying these patterns can help the surgeon decide to perform surgery in these scenarios and choose the fixation technique according to the number and location of the fragments., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest related to content of this article., (Copyright © 2023.

Background: Disc displacement with reduction (DDwR) therapy should be performed only when pain or discomfort is presented. Data on treatment options for painful DDwR are very limited., Objective: The aim was to investigate whether isometric training of the lateral pterygoid muscle (LPM) is equivalent to stabilisation appliance therapy with regard to the treatment of painful DDwR. The training program is based on the science of Janda., Methods: This was a prospective, randomised study with a comparative treatment group. Sixty patients (≥18 years) with DDwR and pain were randomly assigned to two groups: (1) muscle training and (2) stabilisation appliance. The following variables were recorded at baseline examination and after 2, 4 and 6 months: changes in orofacial pain, clicking sounds of the temporomandibular joint (TMJ), force degrees for the lateral movement of the mandible and interincisal opening distance. p values of <.05 were considered statistically significant but 95% confidence intervals were also presented., Results: A decrease in orofacial pain intensity was seen in both groups (p < .0001). Registered TMJ clicking disappeared after 6 months of treatment in 37% (n = 11) of the patients in the training group and in 27% (n = 8) of the appliance group (p = .0009 and p = .0047). Muscle training showed 27 improvements in Janda force degrees at the end of the study (p < .0001)., Conclusion: Muscle training and appliance therapy improved mouth opening and reduced pain intensity in both patient groups. Muscle training might be a promising option in the treatment of patients suffering from painful DDwR., (© 2023 John Wiley & Sons Ltd.)

Background: Anterior repositioning splint (ARS) is used to treat temporomandibular joint (TMJ) disc displacement with reduction (DDwR). However, high recurrence rate remains a problem especially in patients with unstable occlusions., Objective: This study optimised standard ARS therapy and proposed a step-back ARS retraction (SAR) method in adult patients with DDwR., Methods: Dental examinations and magnetic resonance imaging of TMJ were obtained before treatment (T0), 1 to 3 months (T1), 3 to 6 months (T2) and 6 to 12 months (T3) during treatment in 48 adults (average age 27.1 ± 5.7 years). After 3 months of basic ARS wearing, personalised treatment for patients with normal disc-condyle relationship was prescribed depending on bilaminar zone adaptations and severity of molar openbite. SAR which required sequential ARS wearing was designed for patients with deep overbite/overjet until retrodiscal tissue adaptations and stable occlusions were achieved., Results: The maximum interincisal opening was increased from 44.3 ± 6.9 to 45.3 ± 6.3 mm (p < .01), and joint pain was alleviated after ARS treatment. The overall success rate of ARS wearing was 92.1% (58/63) featured by a recaptured disc. Fifteen patients who underwent SAR therapy all showed bilaminar zone adaptations in the end, and one patient had positive condylar bone remodelling., Conclusions: ARS treatment could improve mouth opening and joint symptoms in adult DDwR patients. SAR method was suitable for treating DDwR patients with deep overbite and overjet and improved retrodiscal tissue adaptations and condylar bone remodelling., (© 2023 John Wiley & Sons Ltd.)

Purpose: Radial head subluxation (RHS), also called nursemaid's elbow, is a common injury in young children treated by various health care providers. The diagnosis typically does not require radiographs, but they are often ordered in the emergency room. This study aimed to determine if there was a difference in the efficacy, cost, and amount of radiographs taken in RHS treatment according to the provider, specifically between orthopedic surgeons and pediatricians., Methods: We reviewed the charts of 207 patients presenting with RHS in the emergency department (mean age of presentation = 2.1 years, range: 0.3 to 6.5 years) to determine the provider treating the condition, the number of attempts at reduction, the number of radiographs taken, the post-reduction management, and total hospital cost incurred., Results: One hundred forty-four patients were treated by orthopedic surgeons, 51 by pediatricians, and 13 by residents. The mean number of radiographs obtained was 0.1, 0.8, and 0.5 for groups treated by an orthopedic surgeon, a pediatrician, and a resident, respectively (p = 0.04). The mean cost for reduction of an RHS was $114, $648, and $267 for groups treated by an orthopedic surgeon, a pediatrician, and a resident, respectively (p = 0.04) Conclusion: Although all three groups were effective in treating RHS, there was a significantly reduced hospital cost and a reduced need for radiographs when the provider was an orthopedic surgeon.

Introduction: Patients present to the emergency department (ED) relatively commonly with traumatic closed proximal interphalangeal joint (PIPJ) dislocations, an orthopedic emergency. There is a paucity of teaching models and training simulations for clinicians to learn either the closed dislocated dorsal or volar interphalangeal joint reduction technique. We implemented a teaching model to demonstrate the utility of a novel reduction model designed from three-dimensional (3D) printable components that are easy to connect and do not require further machining or resin models to complete. Methods: Students watched a two-minute video and a model demonstration by the authors. Learners including emergency medicine (EM) residents and physician assistant fellows assessed model fidelity, convenience, perceived competency, and observed competency. Results: Seventeen of 21 (81%) participants agreed the model mimicked dorsal and volar PIPJ dislocations. Nineteen of 21 (90%) agreed the model was easy to use, 21/21 (100%) agreed the dorsal PIPJ model and 20/21 (95%) agreed the volar PIPJ model improved their competency. Conclusion: Our 3D-printed, dorsal and volar dislocation reduction model is easy to use and affordable, and it improved perceived competency among EM learners at an academic ED., Competing Interests: Conflicts of Interest: By the WestJEM article submission agreement, all authors are required to disclose all affiliations, funding sources and financial or management relationships that could be perceived as potential sources of bias.

Background: Injuries to the elbow are frequent in judo combat, but studies on down-time and effect on performance after conservative treatments are rare. This issue is particularly relevant for elbow dislocations in high-performance patients such as elite athletes. The purpose of this study was to evaluate (1) time-loss and (2) the regained level of performance in judoka after conservative treatment of simple elbow dislocation., Methods: In cooperation with the European Judo Union, judoka were asked to complete a 139-item survey regarding elbow injuries they suffered during their career. Besides demographics, injury data, diagnosis and treatment options, the athletes were asked about down-time and reductions in performance level. This study enrolled 108 judoka with conservative treatment of elbow dislocation out of a population of 5426 volunteers., Results: 69% (n=74) reported a time-loss of less than three months; 6% reported a time-loss of more than six months. The majority (68%, n=73) reported that they had returned to their previous performance level, while 22% (n=24) suffered from a slightly reduced level of performance. In the subgroup of international and national athletes (n=54), 63% returned to judo after less than three months, with 72% achieving the same level and 15% reporting a slightly reduced performance level. Level of performance and time lost after conservative treatment for elbow dislocations were comparable for male and female judoka., Conclusion: Approximately two out of three judoka returned to the same level of performance after three months of down-time after undergoing conservative therapy for simple elbow dislocations. Despite the high performance level of the study population, conservative treatment of simple elbow dislocation resulted in satisfactory outcomes. The presented data can guide medical professionals and competitive-level contact-sport athletes with respect to expectations in the process of returning to sport., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Purpose: This observational study aimed to elucidate the pathophysiology of subchondral cysts (SC) in the temporomandibular joint (TMJ) and examine the results of conservative therapy administered to patients with SCs in the TMJ., Methods: The study included 41 patients with SCs, extracted from 684 consecutive patients who underwent magnetic resonance imaging (MRI). The anatomical features of SCs and positional abnormalities of the articular disc were initially evaluated using MRI. A second MRI examination was performed for 28/41 patients at 40-107 months (mean, 66 months) after the first MRI. The joint space, anteroposterior width of the condylar head (WiC), articular eminence angle (AEA), and visual analog scale of jaw pain (VAS) were assessed alongside the MRI examinations., Results: Most SCs were present in the anterosuperior and central condyle. Disc displacement was observed in 100% of 42 TMJs with SCs. Of the 29 joints in 28 patients, SCs in 19 joints resolved with time, whereas SCs in 10 joints persisted. A significant increase in the WiC and a significant decrease in AEA and VAS scores were observed on the second MRI scan., Conclusions: SCs tended to form in the anterosuperior and central parts of the condyle, where mechanical loading was likely to be applied. SCs are strongly associated with articular disc displacement. Two-thirds of SCs resolved over time, accompanied by resorption and osteophytic deformation of the condyle. SC might not be an indicator for the start of surgical treatment, and nonsurgical treatment could improve the clinical symptoms of patients with SCs.

Objective: The aim of the study was to investigate the influence of facemask treatment with skeletal anchorage on the temporomandibular joint (TMJ) using magnetic resonance imaging (MRI), in patients with Class III malocclusion, accompanied by maxillary retrusion., Methods: Fifteen patients with a mean age of 12.1±1.43 years were included in the study. All patients were treated using facemask with skeletal anchorage after eight weeks of Alternate Rapid Maxillary Expansion and Constriction (Alt-RAMEC) protocol. Magnetic resonance imaging was performed before and immediately after facemask treatment for TMJ evaluation. Disc position, condylar translation, degenerative changes of the condyles, and joint effusion were evaluated. To assess whether the alterations associated with the treatment were statistically significant, McNemar and marginal homogeneity tests were used., Results: After facemask treatment, a statistically significant change was observed in the disc position (an anterior disc displacement with/without reduction in five TMJs) (p<0.05). The alteration in the condylar translation was not statistically significant (p>0.05). This treatment did not cause degenerative changes of the condyles or effusion in any of the TMJs., Conclusion: Facemask treatment with skeletal anchorage following the Alt-RAMEC protocol had a minimal influence on the TMJ, only by means of disc position, which was not negligible. Long-term results of such treatment are required for following up the changes observed in the TMJs.

High-energy injuries, including fractures and dislocations, are occurring with increasing frequency in athletic competitions with the increasing size and speed of players. Common fractures and dislocations will be discussed in this article. We will evaluate emergent versus routine injuries and discuss appropriate treatment at the athletic venue. Fractures that can be seen with athletic activities include cervical spine; knee osteochondral fractures; tibia, ankle, and clavicle. Dislocations that will be considered include knee, patella, hip, shoulder, sternoclavicular joint, and proximal interphalangeal joint of the finger. These injuries vary significantly both in severity and in the emergent nature of the injury., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Background: Computed tomography (CT) scans are the standard imaging modality for the diagnosis and treatment guide for adolescent posterior sternoclavicular joint (SCJ) injuries. However, the medial clavicular physis is not visualized and it is not possible to differentiate between a true SCJ dislocation and a physeal injury (PI). An magnetic resonance imaging (MRI) scan can visualize the bone and the physis., Methods: We treated a series of patients with adolescent posterior SCJ injuries diagnosed on CT scan. Patients underwent an MRI scan to differentiate between a true SCJ dislocation and a PI and to further differentiate between a PI with or without residual medial end clavicular bone contact. Patients with a true SCJ dislocation and a PI with no contact underwent an open reduction and fixation. Patients with a PI with contact were treated nonoperatively with repeat CT scans at 1 and 3 months. At final follow-up SCJ clinical function was assessed using Quick-DASH, Rockwood, modified Constant, and single assessment numeric evaluation (SANE) scores., Results: Thirteen patients (2 female and 11 male) with an average age of 14.9 years (12 to 17) were included in the study. Twelve patients were available at final follow-up (mean 50 mo, 26 to 84). One patient had a true SCJ dislocation and 3 had an off-ended PI and were treated with an open reduction and fixation. Eight patients had a PI with residual bone contact and were treated nonoperatively. For these patients serial CT scans showed that the position was maintained, with a serial increase in callus formation and bone remodeling. The average follow-up was 42.9 months (24 to 62). At final follow-up the mean Quick-disabilities of the arm, shoulder and hand (DASH) was 0.4 (0 to 2.3), Rockwood was 15, modified Constant was 98.8 (89 to 100) and SANE was 99.5% (95 to 100)., Conclusion: In this case series of significantly displaced adolescent posterior SCJ injuries MRI scans allowed identification of true SCJ dislocations and off-ended PIs, which were successfully treated by open reduction, and PIs with residual physeal contact which were successfully treated nonoperatively., Level of Evidence: Level IV-case series., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Dislocations of the elbow joint are among the most prevalent dislocation injuries in the human body after shoulder joint dislocations and represent a challenge in the clinical routine because of the concomitant injuries and complications. They predominantly affect young adults who become injured during athletic or daily activities. A distinction is generally made between a simple elbow dislocation and a dislocation fracture of the elbow; however, a uniform classification or treatment algorithm has not yet been established, especially for simple elbow dislocations with associated ligamentous, muscular and capsular concomitant injuries. Due to this and the complexity of this injury, a standardized approach is needed to initiate the optimal treatment at an early stage and to correctly select the narrow treatment pathway between impending chronic instability and elbow stiffness., (© 2023.

Anterior disk displacement (ADD) is a common type of temporomandibular joint (TMJ) internal derangement. In adolescents, the relationship between ADD and dentofacial deformities are brought into focus. Whether treatment is needed, or what kind of treatment are effective are still without a consensus. From the literature review, the consequences of ADD without treatment and the effect on disk repositioning were summarized. The results showed that after ADD, condylar height was prone to reduce that may lead to or aggravate dentofacial deformities in adolescents. Disk repositioning could promote the regeneration of condylar bone, thus improving the development of dentofacial deformities., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: Historically, most Lisfranc injuries have been considered to be unstable and treated with surgical intervention. However, with better access to cross-sectional imaging, stable injury patterns are starting to be recognised. The aims of the current study were to perform a systematic review of outcomes of Lisfranc injuries treated non-operatively., Methods: A literature review was performed of studies reporting nonoperative management of Lisfranc injuries (PROSPERO registered and following PRISMA guidelines). Following exclusions, 8 papers were identified: 1 prospective and 7 retrospective studies. A total of 220 patients were studied with a mean age of 39.8 years and a mean follow-up of 4.3 years. Outcomes included function, displacement, and rates of surgery., Results: High heterogeneity was observed with variable outcomes. Four papers reported good outcomes, with adjusted functional scores ranging from 82.6 to 100 (out of 100). However, one study reported late displacement in 54 % of patients. Rates of secondary osteoarthritis ranged from 5 % to 38 %. Rates of surgical intervention were as high as 56 %. Several studies compared operative to non-operative treatment, reporting superior outcomes with surgery. Those injuries with no displacement on CT, measured at the medial cuneiform-second metatarsal had the best outcomes., Conclusion: Reported outcomes following nonoperative treatment of Lisfranc injuries vary widely, including high rates of conversion to surgery. In contrast, some studies have reported excellent functional outcomes. CT seems to be an important diagnostic tool in defining a stable injury. Due to limited data and lack of a clear definition of a stable injury or treatment protocol, prospective research is needed to determine which Lisfranc injuries can be safely treated nonoperatively., (Copyright © 2023 Elsevier Ltd.

Although uncommon, subtalar joint dislocations remain a frequently missed orthopaedic emergency. Detailed soft tissue and neurovascular assessment is important and these should be documented as appropriate. Failure of urgent reduction might lead to increased risk of conversion to an open injury as a result of pressure necrosis of the overlying skin, risk of talar avascular necrosis and risk of neurovascular compromise. A computed tomography scan is needed in all cases following successful closed or open reduction to identify associated occult foot and ankle fractures. The goal of treatment is to reduce the risk of soft tissue and neurovascular compromise and achieve a supple, painless foot. This article highlights the importance of early identification of this injury and institution of appropriate management according to the latest evidence, to reduce the risk of complications and lead to the best outcomes.

Objective: This study compared clinical and magnetic resonance imaging (MRI) findings in patients with anterior disk displacement without reduction (ADDWOR) who improved to anterior disk displacement with reduction (ADDWR) vs. patients who did not improve after mandibular manipulation (MM) and conservative self-administered physical therapy (CSAPT)., Study Design: Of 15 patients diagnosed with ADDWOR by MRI, 7 improved to ADDWR (WOR-WR) and 8 did not improve (WOR-WOR). The clinical and MRI findings before and after therapy were compared in each group., Results: Significant differences between the groups included age, period of awareness of trismus, and maximum mouth opening (MMO). The MRI findings revealed significant differences in the degree of ADD and morphology of the disk and condyle. MMO significantly improved in the WOR-WR group between initial and follow-up visits., Conclusion: Patients who were successfully treated with MM and CSAPT tended to be <30 years old, with a longer period of awareness of trismus, MMO <40 mm, a slight or moderate degree of ADD, no deformity of the disk, and no morphologic change in the condyle. Patients with ADDWOR who are treated with MM and CSAPT require an accurate clinical examination and MRI before treatment., (Copyright © 2022 Elsevier Inc. All rights reserved.)
