Meta-Analysis
To determine whether subacromial space (i.e. acromiohumeral distance; AHD, and/or occupation ratio percentage) differs between people with subacromial pain syndrome (SAPS) and those without. To investigate whether there is a correlation between subacromial space and pain or disability in adults with SAPS and whether temporal changes in pain or disability are accompanied by changes in subacromial space. Systematic review and meta-analysis. Fifteen studies with a total of 775 participants were included. Twelve studies were of high quality and three studies were of moderate quality using the modified Black and Downs checklist. There was no between group difference in AHD in neutral shoulder position (mean difference [95% CI] 0.28 [-0.13 to 0.69] mm), shoulder abduction at 45° (-0.02 [-0.99 to 0.96] mm) or 60° (-0.20 [-0.61 to 0.20] mm). Compared to the control group, a greater occupation ratio in neutral shoulder position was demonstrated in participants with SAPS (5.14 [1.87 to 8.4] %). There was no consistent pattern regarding the correlation between AHD and pain or disability in participants with SAPS, and no consistent increase in subacromial space with improvement in pain or disability over time. The results suggest that surgical (e.g. sub-acromial decompression) and non-surgical (e.g. manual therapy, taping, stretching and strengthening) management of subacromial pain syndrome should not focus solely on addressing a potential decrease in subacromial space, but also on the importance of other biopsychosocial factors.

Review
BACKGROUND
Radiofrequency has seen an increase in use in orthopedics including cartilage lesion debridement in the hip and knee as well as many applications in arthroscopic shoulder surgery. The purpose of this systematic review is to evaluate the safety and usage of radiofrequency in the shoulder.
METHODS
This systematic review was registered with PROSPERO (international registry) and followed the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines. Embase and PubMed were searched using: "shoulder," "rotator cuff," "biceps," "acromion" AND "monopolar," "bipolar," "ablation," "coblation," and "radiofrequency ablation." The title and abstract review were performed independently. Any discrepancies were addressed through open discussion.
RESULTS
A total of 63 studies were included. Radiofrequency is currently utilized in impingement syndrome, fracture fixation, instability, nerve injury, adhesive capsulitis, postoperative stiffness, and rotator cuff disease. Adverse events, namely superficial burns, are limited to case reports and case series, with higher-level evidence demonstrating safe use when used below the temperature threshold. Bipolar radiofrequency may decrease operative time and decrease the cost per case.
CONCLUSIONS
Shoulder radiofrequency has a wide scope of application in various shoulder pathologies. Shoulder radiofrequency is safe; however, requires practitioners to be cognizant of the potential for thermal burn injuries. Bipolar radiofrequency may represent a more efficacious and economic treatment modality. Safety precautions have been executed by institutions to cut down patient complications from shoulder radiofrequency. Future research is required to determine what measures can be taken to further minimize the risk of thermal burns.

Review
INTRODUCTION
There is no widely accepted standard for the classification and treatment of traumatic acromion/scapular spine fracture nonunion due to the scarcity of this condition and the confusion of terminology.
MATERIALS AND METHODS
PubMed and Scopus were searched using "scapular fracture" and "acromion fracture" or "scapular spine fracture" as search terms. The inclusion criteria were English full-text articles concerning acromion/scapular spine fracture nonunion that described patient characteristics and presented appropriate images. The exclusion criteria were cases without appropriate images. Citation tracking was conducted to find additional articles and notable full-text articles written in other languages. Fractures were classified using our newly proposed classification system.
RESULTS
Twenty-nine patients (19 men, 10 women) with 29 nonunions were identified. There were four type I, 15 type II, and 10 type III fracture nonunions. Only 11 fractures were isolated. The mean period from initial injury to final diagnosis was 35.2 ± 73.2 months (range 3-360 months) (n = 25). The most frequent cause of delayed diagnosis was conservative treatment for fracture in 11 patients, followed by oversight by the physician in 8. The most common reason for seeking medical advice was shoulder pain. Six patients received conservative therapy, and 23 received operative treatment. Fixation materials included various plates in 15 patients, and tension band wiring in 5. Bone grafting was performed in 16 patients (73%, 16/22). Of the 19 surgically treated patients with adequate follow-up, the outcome was rated excellent in 79%.
CONCLUSIONS
Isolated acromion/scapular spine fracture nonunion is rare. Fracture type II and III, arising in the anatomical scapular spine, accounted for 86% of the fractures. Computed tomography is required to prevent fracture oversight. Surgical therapy produces good stable results. However, it is important to select the appropriate surgical fixation method and material after considering the anatomical characteristics of the fracture and stress on the fractured portion.

Review
BACKGROUND
Although fracture of the coracoid process (CF) used to be considered rare, it is now more commonly encountered due to increased awareness and advances in imaging methods. This review aimed to analyze reported cases of CF to determine its mechanism and appropriate treatment.
METHODS
PubMed and Scopus were searched using the terms "scapula fracture" and "coracoid fracture." The inclusion criteria were English full-text articles concerning CF that described patient characteristics with appropriate images. The exclusion criteria included cases without appropriate images and those with physeal injury or nonunion. Citation tracking was conducted to find additional articles and notable full-text articles in other languages. Fractures were mainly classified using Ogawa's classification.
RESULTS
Ninety-seven studies were identified, including 197 patients (131 men, 33 women; average age 37.0±16.9 years). CF was classified as type I in 77%, type II in 19%, and avulsion fracture at the angle in 5%. Concurrent shoulder girdle injuries included acromioclavicular injury in 33%, clavicular fracture in 17%, acromion or lateral scapular spine fracture in 15%, and anterior shoulder instability in 11%. Among patients with type I CF, 69% had multiple disruptions of the superior shoulder suspensory complex. Conservative treatment was applied in 71% of isolated type I CF, while surgical treatment was applied in 76% of type I CF with multiple disruptions. Although the evaluation methods varied, 60% of patients were followed up for more than 6 months, and the outcomes were generally satisfactory for both conservative and surgical treatments.
CONCLUSION
CF occurred commonly in the age group with higher social activity. The most common fracture type was type I. The possible mechanism of CF is violent traction of the attached muscles, except for avulsion fracture at the angle. Type I CF with multiple disruptions of the superior shoulder suspensory complex requires surgical treatment, whereas conservative care is recommended for isolated type I and type II CFs.

Review
INTRODUCTION
Acromioplasty is controversial. Technically, it consists in bone resection, but there is no gold-standard technique and resection is often not quantified. The aims of the present study were 1/to assess the methodological quality of studies of acromioplasty; 2/to identify reports in which acromioplasty was quantified; and 3/to assess any correlation between clinical results and resection quantity.
MATERIAL AND METHODS
A systematic literature review was performed on PRISMA criteria in the PubMed, Springer and Ovid databases, including all articles in French or English referring to acromioplasty. Articles were analyzed by 2 surgeons and those with complete procedural description were selected. 1/Methodology was assessed on 3 grades according to aim of acromioplasty, intraoperative assessment of resection, and postoperative radiologic assessment. 2/Results were extracted from articles with robust methodology and quantitative data. 3/Correlations were assessed between clinical results and resection quantity.
RESULTS
Out of the 250 articles retrieved, 94 were selected. 1/44 of these (47%) specified the aim of the acromioplasty, 53 (56%) included an intraoperative clinical assessment criterion, and 13 (14%) included postoperative radiographic assessment. Methodologic quality was insufficient in 33 articles (35%), poor in 23 (24%) and robust in 38 (40%). 2/Seven articles (7.5%) included quantitative results. 3/Three articles assessed correlation between clinical results and resection quantity, but only 1 used reproducible radiographic assessment by critical shoulder angle (CSA); this study reported a significant positive correlation between clinical results and decreased CSA.
CONCLUSION
Methodology in studies of acromioplasty was largely insufficient and resection was usually not quantified. Current data to assess the usefulness of the procedure are sparse. We advocate including a Checklist for Acromioplasty Studies in the methodology of future studies. There is at present no gold-standard for assessing and quantifying acromial resection. CSA seems contributive, but other methods might be worth developing.

Meta-Analysis Review
PURPOSE
Although tranexamic acid (TXA) is being increasingly used in orthopedic arthroplasty and lower-extremity arthroscopic procedures, its use in arthroscopic rotator cuff repair (ARCR) is less widely reported. The aim of this study was to evaluate the clinical effectiveness and safety of TXA administration in ARCR.
METHODS
A systematic review and meta-analysis of randomized controlled trials was performed to compare clinical outcomes in patients who underwent ARCR with or without TXA. Literature was retrieved using the Cochrane Library, MEDLINE, PubMed, and Embase electronic databases. The primary outcome of this study was visual clarity. Secondary outcomes contained total operative time, postoperative pain score, amount of blood loss, shoulder swelling (change in shoulder circumference), volume of irrigation fluid, number of adjustments of the pump pressure for irrigation, and adverse cardiovascular events.
RESULTS
Seven studies (3 and 4 with level I and II evidence, respectively), which included 272 and 265 patients who underwent arthroscopy with and without TXA, respectively, met the eligibility criteria. Pooled analysis showed significant improvements in visual clarity (mean difference, 9.10%; 95% CI, 4.05-14.15; P = .0004) and total operative time (mean difference, -11.24 minute; 95% CI, -19.90 to -2.57) associated with perioperative TXA application. None of the trials reported adverse events and complications associated with TXA.
CONCLUSION
The best available evidence indicates that TXA administration could significantly improve arthroscopic visual clarity and effectively save operative time in ARCR without increasing the incidence of adverse events. Furthermore, the optimal dose, route, and timing of TXA application in ARCR surgery remains to be validated by future high-level evidence studies.

Review
Fractures of the acromion and the scapular spine are established complications of reverse shoulder arthroplasty (RSA), and when they occur, the continuous strain by the deltoid along the bony fragments makes healing difficult. Evidence on treatment specific outcomes is poor, making the definition of a gold standard fixation technique difficult. The purpose of this systematic review is to assess whether any particular fixation construct offers improved clinical and/or radiographic outcomes. A systematic review of the literature on fixation of acromial and scapular spine fractures following RSA was carried out based on the guidelines of PRISMA. The search was conducted on PubMed, Embase, OVID Medline, and CENTRAL databases with strict inclusion and exclusion criteria applied. Methodological quality assessment of each included study was done using the modified Coleman methodology score to asses MQOE. Selection of the studies, data extraction and methodological quality assessment was carried out by two of the authors independently. Only clinical studies reporting on fixation of the aforementioned fractures were considered. Fixation construct, fracture union and time to union, shoulder function and complications were investigated. Nine studies reported on fixation strategies for acromial and scapular spine fractures and were therefore included. The 18 reported results related to fractures in 17 patients; 1 was classified as a Levy Type I fracture, 10 as a Levy Type II fracture and the remaining 7 fractures were defined as Levy Type III. The most frequent fixation construct in type II scapular spine fractures was a single plate (used in 6 of the 10 cases), whereas dual platin was the most used fixation for Levy Type III fractures (5 out of 7). Radiographic union was reported in 15 out of 18 fractures, whereas 1 patient (6.7%) had a confirmed non-union of a Levy Type III scapular spine fracture, requiring revision fixation. There were 5 complications reported, with 2 patients undergoing removal of metal and 1 patient undergoing revision fixation. The Subjective Shoulder Value and Visual Analogue Scale pain score averaged 75% and 2.6 points, respectively. The absolute Constant Score and the ASES score averaged 48.2 and 78.3 points, respectively. With the available data, it is not possible to define a gold standard surgical fixation but it seems that even when fracture union can be achieved, functional outcomes are moderate and there is an increased complication rate. Future studies are required to establish a gold standard fixation technique.

Meta-Analysis Review
INTRODUCTION
Acromial and scapular spine stress fractures are common complications post reverse shoulder arthroplasty. A systematic review with meta-analysis was conducted to evaluate the clinical outcomes of conservatively treated acromial and scapular spine stress fractures post reverse shoulder arthroplasty in comparison to nonfracture control.
METHODS
Embase, MEDLINE, and Web of Science were searched on September 9, 2022, using various terms related to fracture, acromion, scapula, and reverse shoulder arthroplasty. Meta-analysis using a random effects model was performed on common outcome scores. Risk of bias was assessed using the Joanna Briggs Institute tools for case-controlled studies. Sensitivity analysis was performed for imputed standard deviations and studies with <20 participants.
RESULTS
Thirteen studies with a total of 339 fracture and 3142 control patients were included in the systematic review. Meta-analysis was performed on 12 studies assessing active forward flexion, abduction, external rotation, Constant-Murley score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, pain score, Simple Shoulder Test, and Single Assessment Numeric Evaluation. Fracture patients experienced significantly poorer functional outcome compared with control patients when the fractures were managed conservatively. Levy III fractures tend to experience worse outcomes. Pain score did not demonstrate a statistically significant difference between the fracture and nonfracture cohort.
DISCUSSION
Currently, literature regarding surgical management is lacking, partially because of a dearth of high-quality literature but also hindered by a lack of standardized techniques. This review was limited by inclusion of studies of low evidence, small sample sizes, and inconsistency in outcome measurement and follow-up period. Overall, patients with acromial and scapular spine stress fractures treated conservatively are expected to have reduced shoulder function compared to nonfracture patients, with the spine of scapula fracture patients suffering the poorest outcomes. Future studies should aim to use the same sets of outcomes parameters to assess the patients at fixed time intervals and report outcomes stratified by Levy classification. This will enable interinstitutional collaboration and pooling of results.

Review
BACKGROUND
Anatomic parameters, such as the critical shoulder angle and acromion index, have emerged as methods to quantify scapular anatomy and may contribute to rotator cuff pathology. The purpose of this paper is to investigate the published literature on influences of scapular morphology on the development of re-tears and patient-reported outcomes following rotator cuff repair.
METHODS
A systematic review of the Embase and PubMed databases was performed to identify published studies on the potential influence of scapular bony morphology and re-tear rates and patient-reported outcomes after rotator cuff repair. Studies were reviewed by two authors.
RESULTS
A total of 615 unique titles and 49 potentially relevant abstracts were reviewed, with eight published manuscripts identified for inclusion. Two of three papers reported no relationship between these acromion index and rotator cuff re-tear rate, while one paper found an increased re-tear rate. All three studies on critical shoulder angle found a significant association between critical shoulder angle and cuff re-tear rate. There was no clear relationship between any bony morphologic measurement and patient-reported outcomes after rotator cuff repair.
CONCLUSIONS
Rotator cuff re-tear rate appears to be significantly associated with the critical shoulder angle and glenoid inclination, while not clearly associated with acromial morphologic measurements.

Shoulder & Elbow Apr 2023There is limited evidence examining glenoid osteotomy as a treatment for posterior shoulder instability. (Review)
Review
BACKGROUND
There is limited evidence examining glenoid osteotomy as a treatment for posterior shoulder instability.
METHODS
A search of Medline, Embase, PubMed and Cochrane Central Register of Controlled Trials was conducted from the date of origin to 28th November 2019. Nine out of 3,408 retrieved studies met the inclusion criteria and quality was assessed using the Methodological Index for Non-randomized Studies tool.
RESULTS
In 356 shoulders, the main indication for osteotomy was excessive glenoid retroversion (greater than or equal to approximately -10°). The mean preoperative glenoid version was -15° (range, -35° to -5°). Post-operatively, the mean glenoid version was -6° (range, -28° to 13°) and an average correction of 10° (range, -1° to 30°) was observed. Range of motion increased significantly in most studies and all standardized outcome scores (Rowe, Constant-Murley, Oxford instability, Japan Shoulder Society Shoulder Instability Scoring and mean shoulder value) improved significantly with high rates of patient satisfaction (85%). A high complication rate (34%, = 120) was reported post-surgery, with frequent cases of persistent instability (20%, = 68) and fractures (e.g., glenoid neck and acromion) (4%, = 12). However, the revision rate was low (0.6%, = 2).
CONCLUSION
Glenoid osteotomy is an appropriate treatment for posterior shoulder instability secondary to excessive glenoid retroversion. However, the high rate of persistent instability should be considered when making treatment decisions. Systematic review; Level 4.
