Review
BACKGROUND
Globally, reverse shoulder arthroplasty (RSA) has moved away from the Grammont design to modern prosthesis designs. The purpose of this study was to provide a focused, updated systematic review for each of the most common complications of RSA by limiting each search to publications after 2010. In this part II, the following were examined: (1) instability, (2) humerus/glenoid fracture, (3) acromial/scapular spine fractures (AF/SSF), and (4) problems/miscellaneous.
METHODS
Four separate PubMed database searches were performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Overall, 137 studies for instability, 94 for humerus/glenoid fracture, 120 for AF/SSF, and 74 for problems/miscellaneous were included in each review, respectively. Univariate analysis was performed with chi-square and Fisher exact tests.
RESULTS
The Grammont design had a higher instability rate vs. all other designs combined (4.0%, 1.3%; < .001), and the onlay humerus design had a lower rate than the lateralized glenoid design (0.9%, 2.0%; = .02). The rate for intraoperative humerus fracture was 1.8%; intraoperative glenoid fracture, 0.3%; postoperative humerus fracture, 1.2%; and postoperative glenoid fracture, 0.1%. The rate of AF/SSF was 2.6% (371/14235). The rate for complex regional pain syndrome was 0.4%; deltoid injury, 0.1%; hematoma, 0.3%; and heterotopic ossification, 0.8%.
CONCLUSIONS
Focused systematic reviews of recent literature with a large volume of shoulders demonstrate that using non-Grammont modern prosthesis designs, complications including instability, intraoperative humerus and glenoid fractures, and hematoma are significantly reduced compared with previous studies. As the indications continue to expand for RSA, it is imperative to accurately track the rate and types of complications in order to justify its cost and increased indications.

Review
BACKGROUND
Cost analysis studies in medicine were uncommon in the past, but with the rising importance of financial considerations, it has become increasingly important to use available resources most efficiently.
PURPOSE
To analyze the current state of cost-effectiveness analyses in shoulder surgery.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
A systematic review of the current literature was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. All full economic analyses published since January 1, 2010 and including the terms "cost analysis" and "shoulder" were checked for usability. The methodological quality of the studies was assessed using the Oxford Centre for Evidence-Based Medicine levels of evidence and established health economic criteria (Quality of Health Economic Studies [QHES] instrument).
RESULTS
A total of 34 studies fulfilled the inclusion criteria. Compared with older studies, recent studies were of better quality: one level 1 study and eight level 2 studies were included. The mean QHES score was 87 of 100. The thematic focus of most studies (n = 13) was rotator cuff tears, with the main findings as follows: (1) magnetic resonance imaging is a cost-effective imaging strategy, (2) primary (arthroscopic) rotator cuff repair (RCR) with conversion to reverse total shoulder arthroplasty in case of failure is the most cost-effective strategy, (3) the platelet-rich plasma augmentation of RCR seems not to be cost-effective, and (4) the cost-effectiveness of double-row RCR remains unclear. Other studies included shoulder instability (n = 3), glenohumeral osteoarthritis (n = 3), proximal humeral fractures (n = 4), subacromial impingement (n = 4), and other shoulder conditions (n = 7).
CONCLUSION
Compared with prior studies, the quality of recently available studies has improved significantly. Current studies could help decision makers to appropriately and adequately allocate resources. The optimal use of financial resources will be of increasing importance to improve medical care for patients. However, further studies are still necessary.

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
Total shoulder arthroplasty implant designs have continued to evolve over the years. One recent change has been the shortening of the humeral component to preserve bone stock and to facilitate revision surgery. Despite promising clinical results, radiographic bone adaptions occur frequently in short-stem total shoulder arthroplasty, and limited data exist on short-stem reverse shoulder arthroplasty (RSA). The purpose of this systematic review was to provide an overview about the functional and radiographic outcomes after an uncemented short-stem RSA, as well as identify areas of clinical importance that are underreported in the current literature.
METHODS
A systematic review of the literature was performed in accordance with the PRISMA guidelines using PubMed, Cochrane Central Register of Controlled Trials, and EMBASE. Clinical outcome studies reporting on short-stem RSA outcomes with evidence level I-IV were included. Demographics, clinical and radiological outcomes, as well as complications and revision data were systematically analyzed and described.
RESULTS
Ten studies, published between 2014 and 2019, reporting on 555 shoulders with a mean follow-up of 32 months (range, 20-99.6 months) met the inclusion criteria. For all studies cuff tear arthropathy was the main indication for RSA (36%), followed by primary osteoarthritis (20%). Clinical outcome was reported in nine of ten studies, with range of motion improving in all studies. Six of the seven studies that used the Constant score (CS) demonstrated significant improvement (27.9 points to 69.3 points in weighted means). All studies reported on radiographic changes and bone adaptions. Among these, scapular notching was the most commonly observed (60 out of 327 cases, 18%) but without any described implication on clinical outcomes. No stem loosening was recorded at any final follow-up. A total of 63 complications (12.9%) were reported, with scapula fractures being the most commonly reported complication. Revision surgery was necessary in 24 cases (4.9%).
CONCLUSION
Good clinical results, comparable with long-stem RSAs, are reported at short-term follow-up for short-stem RSAs. Humeral bone adaptions occur frequently but aseptic stem loosening is not a matter of concern at short-term follow-up. An area of clinical importance that is under-reported is the relation between filling ratio and stem alignment in short-stem RSA.

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.

Review
OBJECTIVES
To compile the existing literature on bilateral anterior shoulder dislocation (BASD) and analyze patient demographics, mechanisms of injury, injury characteristics, management, and outcome.
METHODS
This systematic review was conducted in accordance with Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) guidelines. Online databases, including Ovid Medline 1946-, Embase.com 1947-, Scopus 1960-, Cochrane Central, and Clinicaltrials.gov were systematically queried. Studies eligible for inclusion were case reports or case-series, documenting BASD. Two reviewers independently screened and applied a set of a priori exclusion criteria to each returned study. Data were extracted, compiled, and synthesized from each reported case of BASD. Contingency tables/Chi-Square Analyses, T-tests, and univariate regression analyses were conducted to assess relationships between different variables.
RESULTS
Eighty-one studies (87 cases of BASD) were included. Patients were 41.1 (SD± 19.5) years old and most were male (n=63; 72.4%). Around a quarter of patients (28.7%) had a history of epilepsy/seizures or were being worked-up for such. Younger males were more likely to have BASD due to a seizure or electrocution (P<0.05). Close to a third of cases (n=27; 31.0%) were delayed in presentation. Those sustaining seizures or electrocutions were more likely to be delayed in presentation (P=0.013). Most events resulted in simple dislocations that were closed reduced successfully. BASD resulting from seizures or electrocutions were more likely to be fracture-dislocations (P=0.018); and in younger patients with fracture-dislocations, closed reduction was more often to fail or not be attempted (P<0.05). Median follow-up was 6 months (IQR: 3 months - 12 months). Seven patients (10.6%) had complications and 4 (2.3%) demonstrated recurrent instability.
CONCLUSION
In young males presenting with BASD without known trauma, suspicion should be high for a convulsant event. In patients with a known seizure disorder who present with chronic bilateral shoulder or arm pain, BASD should be considered and work-up should be expedited to avoid misdiagnosis.

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
A closed fifth metacarpal neck fracture is a frequently encountered upper limb fracture that occurs when the bone breaks right below the little finger's knuckle. At the moment, there is no agreement on the best way to treat these fractures. This research seeks to look at the efficacy of buddy taping versus reduction and casting for non-operative management of uncomplicated closed fifth metacarpal neck fractures. A systematic review of PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed Central (PMC), and the Cochrane Library databases was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to find relevant studies about buddy taping versus reduction and casting for non-operative management. Disabilities of the arm, shoulder, and hand (DASH) score; satisfaction score; visual analog scale (VAS); range of motion (ROM); strength; and other outcomes were reported in this study. We used Review Manager 5.4 (The Cochrane Collaboration, London, UK) for the meta-analysis. Seven trials with a total of 454 patients were considered in the review and four in the quantitative analysis. All the included studies were randomized controlled trials (RCTs). Our study concluded that buddy taping was effective for improving pain, range of motion, and strength. The DASH score and satisfaction score didn't show any significant difference. Thus, we recommend the use of buddy taping rather than plaster and immobilization for the management of uncomplicated closed fifth metacarpal neck fractures.

Review
This systematic review aimed to identify and describe the utility of functional outcome measures reported in intervention trials between 2010 and 2020, and to map these measures to the International Classification of Functioning, Disability and Health (ICF) model. The search was carried out on MEDLINE, CINAHL and Cochrane Register of Clinical Trials. Peer-reviewed intervention studies detailing the functional outcome measures used for any treatment for distal radius fracture were selected. Participant characteristics, outcome measures reported and the trends in their use over time and geographical locations were extracted. This review analysed 119 studies. Thirty-one functional outcome measures were used across 36 countries. Ninety-two percent of studies measured both the Body Function/Structure and Activity/Participation domains of the ICF. The most frequently used measures were the Disabilities of the Arm, Shoulder and Hand Questionnaire, Range of Motion and Grip Strength. There is a lack of measures on successful return to meaningful occupation. The outcome measures identified were equally spread across the ICF domains. There is a growing importance of Patient-Reported Outcome Measures to supplement performance-based measures, but a lack of measure on successful return to meaningful occupation.

PURPOSE
The goal of this study was to review available literature on periprosthetic shoulder fractures to evaluate epidemiology, risk factors and support clinical decision-making regarding diagnostics, preoperative planning, and treatment options.
METHODS
Two authors cross-checked the PubMed and Web of Science medical databases. The inclusion criteria were as follows: original human studies published in English, with the timeframe not limited, and the following keywords were used: 'periprosthetic shoulder fracture,' 'total shoulder arthroplasty periprosthetic fractures,' 'total shoulder arthroplasty fracture,' and 'total shoulder replacement periprosthetic fracture.' Seventy articles were included in the review. All articles were retrieved using the aforementioned criteria.
RESULTS
The fracture rate associated with total shoulder arthroplasty varied between 0 and 47.6%. Risk factors for periprosthetic fractures were female gender, body mass index < 25 kg/m2, smoking, rheumatoid arthritis, and Parkinson's disease. The most commonly used classification is the Wright and Coefield classification. Periprosthetic fractures can be treated both, conservatively and operatively.
CONCLUSION
Periprosthetic fracture frequency after shoulder arthroplasty ranges from 0 to 47.6%. The most common location of the fracture is the humerus and most commonly occurs intraoperatively. The most important factor influencing treatment is stem stability. Fractures with stem instability require revision arthroplasty with stem replacement. Fractures with a stable stem depending on the location, displacement and bone stock quality can be treated both conservatively and operatively. For internal fixation plates with cables and screws are most commonly used.
