Introduction: hip fractures in elderly patients have been associated with high morbidity and mortality rate and are dependent on the presence of associated comorbidities. SARS-CoV-2 disease (Covid-19) is nowadays considered to be an independent risk factor increasing mortality rates. The aim of our report was to analyse the management of a vaccinated versus a non-vaccinated elderly patient that were both diagnosed positive to SARS-CoV-2 after having sustained an intracapsular neck of femur fracture. Methods: Two patients (Patient A 91 and Patient B 88 years old, both female) were referred to our hospital after sustaining an intracapsular neck of femur hip fracture as a result of low energy trauma. Both patients tested positive for Covid-19 during their preoperative screening tests. Patient A had not been vaccinated against Covid-19 in contrast to patient B who had completed the 2 dose regimen of the Pfizer-BioNTech COVID-19 vaccine. Patient A presented on arrival Leukopenia (WBC: 1.2 µc/l, Neutrophils 0.4 mcL ) and Thrombocytopenia (PLT 70.000 ). The Procalcitonin, C-Reactive Protein and Ferritin levels long as Arterial blood Gases were measured in both patients on arrival. Patient A required administration of Granulocyte colony stimulating factor and platelet transfusion prior to surgery. Results: Both patients underwent uncemented hip hemiarthroplasty. Patient A was operated 5 days after hospital admission as optimization of the patient's Covid-19 related Leukopenia and Thrombocytopenia was required and Patient B was operated within 24 hours after hospital admission. Patient A required transfusion of 4 blood Units (bleeding related to Thrombocytopenia) compared to 2 blood units that were administered in Patient B. Patient A developed Covid 19 related Pneumonia and Lung disease on the 6th postoperative day (PO2 SO2 ) and required high flow nasal cannula therapy for 7 days followed by oxygen therapy for 8 days delaying her mobilization and hospital discharge. Patient A was discharged on the 29th post-operative day and Patient B was discharged on the 6th post-operative day. Conclusion: Covid 19 related complications in elderly hip fracture patients are challenging and require multidisciplinary approach and hospital resources. However, Vaccination against covid-19 seems to prevent Covid related complications and can improve the outcome. Large series studies and further research is required to support our thesis.

Purpose: The long-term failure rate of the arthroscopic Bankart repair may reach unacceptable values, raising the need to augment this classic procedure. Arthroscopic subscapularis augmentation is the tenodesis of the upper part of the subscapularis tendon to the anterior glenoid rim. The aim of the study was to evaluate the mid-term clinical and functional outcomes of patients operated with arthroscopic subscapularis augmentation of the classic Bankart repair due to recurrent anterior shoulder instability., Methods: This is a retrospective single-centre case series study with prospectively collected data. All patients suffered from recurrent anterior shoulder instability and had glenoid bone loss less than 13.5% of the inferior glenoid diameter (subcritical glenoid bone loss). Patients with greater anterior glenoid bone defect, engaging Hill-Sachs lesions, multidirectional instability or subscapularis insufficiency were excluded. Postoperatively, all patients were evaluated for recurrence and apprehension. The patient's shoulder range of motion and functional scores were recorded., Results: The final study cohort included 34 patients with a mean age of 29.3 ± 10.2 years. The mean follow-up period was 42.4 ± 10.7 months (range, 24-62 months). Two out of 34 patients (5.8%) experienced a re-dislocation postoperatively, while one additional patient had a subjective feeling of apprehension. External rotation at the last follow-up was lower compared to preoperative values or the healthy side, but only one patient had restrictions in his sporting activities. The functional scores were significantly increased compared to the preoperative values. Twenty-two out of 26 patients (84.6%) returned to the same level of sporting activities, and 30/34 patients (88.2%) were highly satisfied with the results., Conclusion: Arthroscopic subscapularis augmentation of the classic Bankart repair reduces the dislocation recurrence rate and leads to satisfactory clinical and functional mid-term outcomes in patients with recurrent anterior shoulder instability and less than a subcritical glenoid bone loss., Level of Evidence: Level IV., (© 2024 European Society of Sports Traumatology, Knee Surgery and Arthroscopy.)

The incidence of proximal femur fractures is increasing due to aging of the population. Intramedullary nails are the mainstay of treatment for intertrochanteric hip fractures mainly due to their better biomechanical properties compared to dynamic hip screw devices, shorter operative time, and less blood loss during surgery. However intramedullary nail fixation is not devoid of complications. The purpose of this study is to look at complications related to intramedullary nailing for intertrochanteric hip fractures in a major trauma center. A retrospective study was conducted including all patients having suffered an intertrochanteric femur fracture and treated with intramedullary nails from October 1, 2020, to October 1, 2022, in the Orthopaedic Surgery Clinic. The intramedullary hip systems used were the Stryker Gamma3 Nail and the VITUS PF Nail. All complications following the postoperative period were recorded in detail. Overall, 240 patients with a mean age of 82.3 years treated with hip intramedullary devices were identified. Superior cutout of the lag screw in two patients (females 90 and 87 years old) was identified 8 and 10 weeks following initial surgery. Avascular necrosis (AVN) of the femoral head was identified in one patient (male 81 years old) which occurred 12 weeks postoperatively. All three cases were revised by replacing the nail with cemented hemiarthroplasty. Periprosthetic fractures occurred in an 88-year-old male and a 73-year-old female following an injury distal to the stem and were managed by replacing the nail with a long stem device (Long Gamma3). One case of metalwork fracture was also recorded. There are many advantages in managing intertrochanteric hip fractures with intramedullary hip devices such as shorter theater time, less blood loss, and improved biomechanical properties. However, complications such as cutout of the lag screw, AVN, and periprosthetic fracture are serious and require complex revision surgery.

Although tuberculosis (TB) is considered to be a common disease confined to undeveloped or developing countries, it may also appear in countries that accept great migrant influx from endemic areas. In terms of the skeletal system, it can be involved in 1-6% of tuberculosis patients while the knee joint is the third most frequently affected site after spine and hip. Given that systemic symptoms are present in only one-third of patients with skeletal tuberculosis and secondary septic arthritis, TB is often indolent and diagnosis can hence be missed or delayed. As a result, a high index of suspicion is imperative. Here, we aim to report a case of mono-arthritis caused by Mycobacterium tuberculosis in a native 77-year-old man who was suffering from low-grade knee pain for six months and despite multiple presentations to the Accident and Emergency department, diagnosis had not been established.

The coronavirus disease 2019 (COVID-19) pandemic has led to important restrictions in social life of civilians worldwide and there were lower admission rates mainly in surgical departments in many hospitals. This study presents how COVID-19 pandemic affected admissions at the orthopaedic and trauma surgery department of a major trauma center. A retrospective study was conducted that recorded all patients examined at the outpatient orthopaedic clinic and the emergency orthopaedic department, as well as patients admitted to the orthopaedic surgery clinic and patients that underwent operative procedures between March 23 and May 4, 2020 (first lockdown period) and between March 23 and May 4, 2019 (control period). In addition, all patients with hip fractures that required hospitalization and underwent hip surgery were identified during the same time periods. During lockdown period 1 compared with the lock-down period 2 were observed: 70% and 61% decrease in the number of patients examined at the outpatient clinic and the emergency orthopaedic department respectively. The number of patients admitted to the orthopaedic surgery clinic declined by 41%, whereas operative procedures decreased by 22%. Regarding hip fractures timing to surgery during the first period was significantly less compared with second lockdown period, however, hospitalization days remained almost unchanged over the two time lockdown periods. Restrictions during the first lockdown period due to COVID-19 pandemic caused an important decrease in the number of patients and theaters in all orthopaedic departments in one of the major trauma centers in Athens. However, the incidence of hip fractures in elderly was not significantly decreased. Further similar studies are needed to identify variations and patterns of these parameters in other trauma centers.

One of the most important complications of pelvic injuries is hemorrhage which can be attributed to the venus plexus of the pelvis, the damaged bone on the fracture site, or in 15% of cases to arterial cause. In the last case mortality could reach 70%. Clinical case presentation, a 77-year-old man, presented in the emergency department of our hospital hemodynamically unstable due to fall from height (3 meters) with comminuted bilateral fractures of the pubic rami, right sacral and iliac wing fracture, right acetabular fracture, fractures of transverse processes of the first, second, and fifth lumbar spine vertebrae and a periprothetic fracture of the right femur. Advanced trauma life support (ATLS) protocol was followed throughout. Computed tomography (CT) scans and CT angiography performed, showed the above mentioned pelvic fractures that did not require stabilization, without further injuries, and a well described retroperitoneal hematoma without any evidence of active bleeding. During the resuscitation process the patient developed cardiac arrest and cardiopulmonary resuscitation (CPR) protocol was followed. The patient was intubated and retained his cardiac rhythm. However, he remained unstable and an angiography was then performed that revealed internal iliac artery bleeding and embolism of the internal iliac artery was performed. The patient was stabilized and was transferred to the intensive care unit for further management. Arterial hemorrhage due to pelvic injury is less common, however presents with high rates of mortality. CT angiography may in some cases not reveal existing active bleeding, misleading the clinician. Therefore, in patients with high clinical suspicion of arterial pelvic hemorrhage who remain unstable during the initial resuscitation and do not present with other primary source of bleeding, an angiography and embolism should be performed as soon as possible.

Background: A number of papers have been published comparing the safety and efficacy of day case and inpatient anatomic or reverse total shoulder arthroplasty. However, no systematic review of the literature has been published to date. The aim of this review was to determine if day case total shoulder arthroplasty (length of stay <24 h) leads to similar outcomes as standard-stay inpatients (length of stay ≥24 h)., Methods: The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviewers were queried for publications utilizing keywords that were pertinent to total shoulder arthroplasty, day case, outpatient and inpatient, clinical or functional outcomes, and complications. In order to determine the quantitative impact of day case total shoulder arthroplasty on readmission and revision rate, a meta-analysis was performed on articles that observed 30- or 90-day readmission or revision., Results: Eight articles were found to be suitable for inclusion in the present study which included 6103 day case total shoulder arthroplasty and 147,463 inpatient total shoulder arthroplasty. Following meta-analysis, there was no significant difference among patients who underwent day case total shoulder arthroplasty compared to inpatient total shoulder arthroplasty regarding revision rates (OR: 1.001; 95% CI: 0.721-1.389; p = 0.995) and 30-day readmission rates (OR: 0.940; 95% CI: 0.723-1.223; p = 0.646). In contrast, patients who underwent day case total shoulder arthroplasty were less likely to have a readmission within 90 days compared to their inpatient counterparts (OR: 0.839; 95% CI: 0.704-0.999; p = 0.049). Two out of eight studies reported comparable baseline clinical characteristics among groups, while five studies reported significant differences and one study did not provide information regarding clinical characteristics, such as medical comorbidities or American Society of Anaesthesiologists'(ASA) score. No significant difference among groups was found in all or almost all studies regarding mortality rates, and rates of cardiac complications, cerebrovascular events, thromboembolic events, pulmonary complications, cardiac complications, and nerve complications. Finally, results were rather conflicting regarding the correlation of day case total shoulder arthroplasty to the rate of surgical site infections., Conclusions: This study showed that day case total shoulder arthroplasty might lead to similar rates of mortality, complications, revisions, and readmissions compared to inpatient total shoulder arthroplasty when used in a selected population of younger, healthier, and more male patients. In contrast, there was no consensus regarding the impact of day case total shoulder arthroplasty on the rate of surgical site infections. Finally, further research of higher quality is required to establish patient demographic criteria, ASA score, or comorbidity index cut off that might be used to define day case-treated patients who seem to have equivalent outcomes compared to inpatient-treated patients.

Background: Several articles have been published reporting on the clinical performance of a novel pegged, all-polyethylene glenoid component design which features a central peg, circumferentially fluted, interference-fit peg for tissue integration and three small peripheral pegs for cementing. However, no systematic review exists to this date., Methods: The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried for publications up to May 2020., Results: Overall, 13 articles were included for analysis (560 operated shoulders, range of mean follow-up: 2-6 years). The survival rate was 98.2% (550 out of 560 cases), while the rate of aseptic loosening was 0.2% (1 out of 560 cases). There were 139 cases (out of 399 reported; 34.1%) with peri-glenoid radiolucency, and 35 cases (out of 223 reported; 15.7%) of asymptomatic central peg osteolysis, with 1 of them undergoing revision., Conclusions: There was fair quality of evidence to show that partially cemented all-polyethylene pegged bone-ingrowth glenoid components produce promising results, with a low revision rate in the short- to medium-term follow-up. Nevertheless, this analysis showed high rates of both radiolucency of the glenoid component and osteolysis around the central peg which raise concern for potential failure of this glenoid component in the long-term follow-up., Level of Evidence: Systematic review, IV., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2020 The British Elbow & Shoulder Society.)

Purpose  To answer the question whether bilateral reverse total shoulder arthroplasty (RTSA) is a safe and effective treatment which results in satisfactory clinical and functional outcomes with low complications rates. A second question to be answered was: what is the quality of the evidence of the already published studies which investigate the use of bilateral RTSA? Methods  Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "reverse" AND "total" AND "shoulder" AND "arthroplasty" AND "clinical." Descriptive statistics were used to summarize the data. Results  From the 394 initial studies we finally selected and assessed 6 clinical studies which were eligible to our inclusion-exclusion criteria. The aforementioned studies included in total 203 patients (69% females; mean age range: 67.1-75 years; mean follow-up range: 12-61 months). From those, 168 patients underwent staged bilateral RTSA (mean duration between first and second operation range: 8-21.6 months) and the rest of them a unilateral RTSA as controlled treatment. Almost all mean clinical and functional scores, which were used to assess the therapeutic value of bilateral RTSA, depicted significant postoperative improvement in comparison with the mean preoperative values. The modified Coleman methodology score, which was used to assess the quality of the studies, ranged from a minimum of 36/100 to a maximum of 55/100. Conclusion  Despite the lack of high-quality evidence, staged bilateral RTSA seems to be a safe and effective procedure for patients with cuff tear arthropathy, which results in significantly improved clinical and functional outcomes and low reoperations' rates.

Background: New types of glenoid bone block fixation, involving suture buttons, suture anchors or even implant-free impaction of the graft, have been recently introduced. In contrast to screws which allow for a rigid fixation of the bone block, these alternative procedures provide a non-rigid type of fixation., Methods: Two reviewers independently conducted the search in a systematic way (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "Latarjet" OR "Eden-Hybbinette" OR "bone block" AND "anterior" AND "shoulder" AND "instability.", Results: Eight out of the 325 initial studies were finally chosen according to our inclusion-exclusion criteria. In total, 750 patients were included in this review. The overall anterior instability recurrence rate for patients treated with non-rigid fixation was 2.6%, while the overall rate of non-union or graft osteolysis was 5.4%., Conclusions: Regardless of the graft type, bone block non-rigid fixation showed satisfactory clinical and functional outcomes for the treatment of anterior shoulder instability with substantial glenoid bone deficiency. Furthermore, non-rigid fixation resulted in adequate bone graft healing and osseous incorporation. Lastly, given the relative lack of data, further prospective controlled studies are required to assess bone block non-rigid fixation procedures in comparison with the traditional rigid (with screws) fixation techniques., Level: Systematic review, IV., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2019 The British Elbow & Shoulder Society.)

Purpose: Suture anchors have revolutionized arthroscopic surgery, enabling direct soft tissue-to-bone repair. There are many types of anchors still used in arthroscopic shoulder operations. We sought to compare the clinical outcome of all-suture and biocomposite anchors when used in arthroscopic Bankart repair for patients suffering from anterior shoulder instability., Methods: A single-center retrospective cohort study of 30 patients (mean age: 26.6 years, SD: 8.8 years, male/female ratio: 5/1, mean follow up: 28 months, SD: 23.8, range: 12-92) with anterior shoulder instability was conducted. Patients were divided into 2 groups based upon the type of suture anchors used for the Bankart repair: group A (14 patients) used only all-suture anchors and group B (16 patients) used only biocomposite anchors. Outcomes reported were postoperative dislocations, positive shoulder apprehension test, self-reported sense of shoulder instability, return to activities of daily living, return to sports, patient satisfaction and complications. Patient reported outcome measures (PROMs) used were the Rowe Score for Instability, Constant Shoulder Score, Walch Duplay Score, The American Shoulder and Elbow Surgeons (ASES) Shoulder Score, Oxford Shoulder Instability Score and external rotation at 90° of arm abduction, external rotation at 0° of arm abduction, forward flexion, abduction, adduction and internal rotation., Results: Rates of postoperative shoulder dislocation demonstrated no significant difference between the 2 groups (p > .05). Four postoperative dislocations happened, two in each group (14.3% and 12.5% for all suture only and biocomposite only groups, respectively), with three of them being traumatic. In addition, no significant differences were observed amongst groups regarding shoulder apprehension test (group A: 85.7% vs. group B: 93.8%), sense of shoulder instability (7.1% vs. 6.3%), return to activities of daily living (group A: 85.7% vs. group B: 93.8%), return to sports (group A: 85.7% vs. group B: 87.5%), patient satisfaction (moderate level: group A 21.4% vs. group B 12.5%), and PROMs., Conclusion: The short-term failure rate and clinical/functional outcomes of arthroscopic Bankart repair using all-suture anchors is similar to the use of biocompatible anchors., Level of Evidence: Level III, retrospective cohort study., Competing Interests: MM: Unpaid Consultant for Lima Inc.

Purpose: To evaluate the clinical, functional, and radiological midterm outcomes of the all-arthroscopic modified Eden-Hybinette procedure in patients with recurrent anterior shoulder instability., Methods: A retrospective, single-center case series with prospectively collected data was conducted. The inclusion criterion was traumatic recurrent anterior shoulder instability with significant glenoid bone loss; patients with atraumatic or multidirectional instability were excluded. An all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and double-pair button fixation was carried out. All patients were postoperatively assessed for recurrence and apprehension. Shoulder range of motion values and functional scores, including American Shoulder and Elbow Surgeons Score, Oxford instability, Rowe instability, and Walch-Dupplay, were recorded. Graft positions, healing, and absorption were evaluated with computed tomography. Comparisons of values were performed with paired t tests for normally distributed differences and with nonparametric Wilcoxon's signed rank test otherwise., Results: The final study cohort included 28 patients, mean age 36 ± 10 years, and mean follow-up period 43 ± 6 months (range 36 to 53). Median glenoid bone loss was 12.4% (range 8% to 33%). No recurrence occurred, no subjective shoulder instability was reported, and no major complications were documented through the last follow-up. Postoperative shoulder range of motion had no significant differences compared with the healthy side. All final postoperative functional scores significantly increased to show excellent results compared with preoperative values. All grafts were positioned and healed optimally, and none was completely reabsorbed., Conclusions: The all-arthroscopic modified Eden-Hybinette procedure is safe, leading to excellent clinical and radiological midterm outcomes in patients with recurrent anterior shoulder instability. This technique restores glenoid bone defects and preserves the normal shoulder anatomy., Level of Evidence: IV, therapeutic, retrospective case series., (Copyright © 2020 Arthroscopy Association of North America.

Background: A number of papers have been published reporting on the clinical performance of modern trabecular metal-backed glenoid components in total shoulder arthroplasty. However, no systematic review of the literature has been published to date., Methods: The US National Library of Medicine (PubMed/MEDLINE), and the Cochrane Database of Systematic Reviews and EMBASE were queried for publications from January 1980 to October 2019 utilizing keywords pertinent to total shoulder arthroplasty, trabecular metal, and clinical outcomes., Results: Overall, seven articles were included for analysis (322 operated shoulders, mean follow-up range: 2-4 years). The survival rate of modern trabecular metal-backed glenoid components was 96% (309 out of 322 cases) at 43 months mean follow-up, while the rate of aseptic loosening was 0.3% (1 out of 322 cases). There were 35 cases (10.9%) with glenoid component radiolucency (one of them required revision), and 37 cases (11.5%) of metal debris formation, with four of them undergoing revision., Conclusions: There was low quality evidence to show that the use of modern trabecular metal-backed glenoid components in total shoulder arthroplasty may be safe and effective at short-term follow-up. However, this analysis showed alarmingly high rates of both radiolucency of the glenoid component and metal debris formation which raise concern for potential failure of this glenoid component in the long term. Therefore, we feel that modern trabecular metal-backed glenoid components should be still used with caution as part of a structured surveillance or research program until we know if there is a detriment to the prosthesis in the medium to long term.

Background: A number of clinical trials have been published assessing the role of iliac crest bone grafting for the management of recurrent anterior instability with glenoid bone loss in contemporary practice. We therefore performed a systematic review of contemporary literature to examine the effect of iliac crest bone grafting on postoperative outcomes of these patients. Our hypothesis is that contemporary iliac crest bone block techniques are associated with low reoperation and complication rates combined with satisfactory functional results., Methods: The US National Library of Medicine (PubMed/MEDLINE), the Cochrane Database of Systematic Reviews, and EMBASE were searched between January 2008 and December 2019 for relevant publications., Results: Following the application of the inclusion-exclusion criteria, nine articles were found eligible for our analysis. In total, 261 patients (mean age range, 25.5-37.5 years; mean follow-up range, 20.6-42 months) were included in the studies of the current review. The mean modified Coleman score was 48.6 (range 37-65), indicating an overall low-to-moderate methodological quality. In the short term, the overall all-cause reoperation rate was 6.1%, while the rate of recurrent instability was 4.8%. The graft non-union rate was 2.2%, while the rate of osteolysis, graft fracture, and infection was 0.4%, 0.9%, and 1.7%, respectively. Finally, hardware-related complications, such as screw breakage or symptomatic mechanical irritation around the screw insertion, occurred in 3.9% of the patients., Conclusions: Iliac crest bone block techniques in contemporary practice are safe and effective in the short-term (< 4 years) follow-up for the management of anterior shoulder instability with substantial glenoid bone deficiency. However, further studies of higher quality and longer follow-up are required to establish the therapeutic value of these techniques as well as to clarify whether there are differences in the outcomes of arthroscopic and open iliac crest bone block procedures.

Purpose  This study aims to investigate the clinical and functional outcomes of the all-arthroscopic McLaughlin procedure in a clinical series of patients suffering by neglected locked posterior shoulder dislocation. Methods  A retrospective clinical study based on prospectively collected data was conducted in a single center regarding 10 patients with neglected locked posterior shoulder dislocation and concomitant reverse Hill-Sachs lesion, who were treated with the all-arthroscopic Mclaughlin procedure. The average humeral bone defect was 39 ± 7% according to the preoperative computed tomography evaluation. The mean time of follow-up was 77 ± 16 months (range, 63-104 months). Results  No patient had suffered a new dislocation, whereas all of them were satisfied with the surgical outcome and returned to their previous activities of daily living. External rotation was restored to every patient studied from 0 degrees at the baseline. At the last follow-up, the median external rotation beside the body was 90 degrees (range, 50-90 degrees; p  < 0.01) and the respective measurement at 90 degrees of abduction was 90 degrees (range, 80-90 degrees; p  < 0.01). The active forward flexion was increased ( p  < 0.01), from 60 degrees (range, 30-180 degrees) at the baseline to 180 degrees (range, 160-180 degrees) at the last follow-up and the internal rotation was gained ( p  < 0.01) from the level of buttock (range, lateral thigh-T12) at the baseline to the T11 level (range, T7-L3) at the last follow-up. The median UCLA score was increased from 8 (range, 4-22) to 35 (range, 33-35; p  < 0.01) and the Oxford instability score from 5 (range, 3-16) to 46 (range, 43-48; p  < 0.01), respectively. Conclusion  The arthroscopic McLaughlin procedure in substantial reverse Hills-Sachs lesion caused by locked posterior dislocation leads to excellent clinical and functional results in the long-term follow-up.

Purpose: We performed a systematic review of the studies including clinical/functional outcomes and complications of bone grafting for glenoid defects in reverse total shoulder arthroplasty (RTSA)., Methods: The PubMed and Cochrane databases were searched for relevant papers., Results: Thirteen articles were included. The mean clinical/functional subjective scores significantly improved postoperatively. The implant revision rate for primary and revision RTSA was 3.1% and 21.1% respectively. The reoperation rate was 3.5% and 24.4% respectively., Conclusions: There was moderate evidence that bone grafting is effective for glenoid defects in primary RTSA. Further high-quality research is required about revision RTSA for moderate-to-severe glenoid defects., Competing Interests: None., (© 2019 Professor P K Surendran Memorial Education Foundation.

Purpose: To answer the question whether arthroscopic subacromial balloon spacer (InSpace Balloon-ISB) implantation results in improved outcomes in patients suffering by irreparable massive rotator cuff tears (MRCT). Secondarily, we aimed to compare the outcomes of a combined ISB and arthroscopic partial repair procedure with those of a single ISB implantation without any repair., Methods: A retrospective single-centre case series, based on prospectively collected data of patients who were suffering by irreparable MRCT, was conducted. An ISB implantation along with an arthroscopic non-anatomic repair or debridement was carried out in all patients included in this study. Patients were functionally evaluated with the use of the American Shoulder and Elbow Surgeons Shoulder Score and the Constant score. Individual's pain was pre- and postoperatively measured with the Visual Analogue Scale (0-100/100). Patients' satisfaction and postoperative complications were also documented. As for the active range of motion (RoM), shoulder's forward flexion, external rotation at 0° and of 90° of abduction, and internal rotation were also pre- and postoperatively assessed., Results: Thirty-one patients [mean age: 65.2 years, standard deviation (SD): 8.5, and range: 50-80 years] with a mean follow-up of 22.1 months (SD: 9.8; range: 6-31 months) were reviewed. All final postoperative clinical and functional scores were significantly improved in comparison with the preoperative values (p < 0.05). The vast majority of the patients declared fully or almost fully satisfied with their treatment (80.6%), while most patients were free of pain at their last follow-up (83.9%). We identified 18 patients (group A), who were treated with a combined ISB implantation and arthroscopic non-anatomic repair and 13 patients (group B) who received an ISB implant without any repair. The long head of biceps, where existed, was tenotomized in both groups. No significant difference was found between the baseline demographic and clinical characteristics of the two groups. As for the mean final postoperative scores and RoM, the differences between the two groups were insignificant (p > 0.05)., Conclusions: The use of ISB implantation for patients suffering by MRCT leads to significantly improved mid-term outcomes and high patents' satisfaction. The additional use of arthroscopic partial repair with ISB was not proven superior to the single ISB implantation., Level of Evidence: IV; therapeutic case series.

We describe an arthroscopic technique for the management of glenoid rim fractures. It is performed with the patient placed in lateral decubitus position. The fracture is assessed through the anterosuperior portal, and the fragment is mobilized. A special glenoid guide is used from the posterior portal to reduce the fragment and to create 2 tunnels through the glenoid and through the glenoid rim fragment. Two pairs of round buttons are connected with high-strength sutures and are tightened posteriorly. This allows strong fixation of the fractured fragment and avoids all the anterior structures since all the instruments are inserted posteriorly., (© 2019 by the Arthroscopy Association of North America.

Purpose: To investigate whether the 'Surgilig' technique is safe and effective for the treatment of patients suffering from acromioclavicular joint (ACJ) dislocations graded as Rockwood's type III or higher., Methods: A systematic review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines., Results: The failure rate of the "Surgilig" implant was very low (3.5%), while patients' satisfaction was high (88.3%). However, the quality of most studies was low., Conclusions: There is low evidence to show that the reconstruction of ACJ dislocations with the 'Surgilig' technique could be a safe and effective treatment., (© 2019 Professor P K Surendran Memorial Education Foundation.

Purpose: To investigate whether arthroscopic Latarjet procedure significantly differs from the open procedure as for the clinical, functional and radiographic outcomes., Methods: Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "shoulder" AND "anterior" AND "instability" AND "Latarjet"., Results: From the 259 initial papers, we finally assessed five clinical studies which were eligible to our inclusion-exclusion criteria. The mean modified Coleman score for methodological deficiencies of the studies was 65.4/100, whereas it ranged from 53/100 to 77/100. The arthroscopic technique illustrated comparable results to the open technique regarding the postoperative recurrence rate. No significant difference was found amongst groups in relation to the postoperative osteoarthritis, infection rates, soft tissue healing, postoperative mean American Shoulder and Elbow Surgeons score, mean Walch-Duplay score, fatty infiltration of the subscapularis muscle and posterior protrusion of the screw. The arthroscopic technique yielded significantly superior results as for the non-union rate of the graft, the total graft osteolysis and graft resorption, the mean Western Ontario Shoulder Instability Index score and the early postoperative pain., Conclusions: Both the open and the arthroscopic Latarjet procedures led to satisfactory radiographic and clinical outcomes for the treatment of patients with recurrent anterior shoulder instability and significant glenoid bone loss. However, the overall quality of the studies ranged from low to moderate., Level of Evidence: Comprehensive and systematic review of level II-III therapeutic studies.

We aimed to investigate whether combined reverse total shoulder arthroplasty (RTSA) and subscapularis repair leads to improved clinical and functional outcome in comparison with RTSA alone. Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "reverse" AND "shoulder" AND "arthroplasty" AND "with" AND "subscapularis" AND "repair". From the 72 initial studies, we finally chose five studies which were eligible to our inclusion-exclusion criteria. The total mean modified Coleman methodology test was 55/100 (range: 47/100 to 60/100). The eligible studies included 1087 patients, in total. Regarding the subjective functional scores as well as range of motion (ROM), the differences amongst groups were insignificant in almost all studies. The mean complications' rate of the repair group was 10.4%, whereas the respective rate of the nonrepair group was 10.2%. All studies concluded that the repair of subscapularis did not affect the complications' rate of patients who were treated with RTSA. The mean dislocations' rates of the repair and the nonrepair group were 1.5% and 2.3%, respectively. Although subscapularis repair was proven safe and effective for the augmentation of RTSA, it did not offer any additional clinical or functional benefit in the outcome of patients treated with lateralized RTSA. Therefore, it is not supported its routine use for patients who have a preoperatively sufficient subscapularis tendon., Competing Interests: Conflict of interest: there authors declare no potential conflict of interest., (©Copyright: the Author(s), 2019.)
