Assessing the use of the frequency, etiology, direction, and severity classification system for shoulder instability in physical therapy research - A scoping review. Phys Ther Sport 2024; 66:76-84. [PMID: 38359729 DOI: 10.1016/j.ptsp.2024.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/17/2024]
Abstract
OBJECTIVE The aim of this study is to review the implementation of the Frequency, Etiology, Direction, and Severity (FEDS) classification for shoulder instability by the physical therapy scientific community since its publication in 2011. METHODS A systematic search was conducted on January 10, 2024 in the MEDLINE, EMBASE, SPORTDiscus, Scopus, Web of Science, Cochrane, and SciELO databases, as well as Google Scholar. Studies investigating physical therapy interventions in people with shoulder instability, and reporting selection criteria for shoulder instability were considered eligible. A narrative synthesis was conducted. RESULTS Twenty-six studies were included. None reported using the FEDS classification as eligibility criteria for shoulder instability. Only 42% of the studies provided data of all four criteria of the FEDS classification. The most reported criterion was direction (92%), followed by etiology (85%), severity (65%), and frequency (58%). The most common reported descriptor for profiling shoulder instability was "dislocation" (83.3%), followed by "first-time" (66.7%), "anterior" (62.5%), and "traumatic" (59.1%). Regarding other instability classifications, only one study (4%) used the Thomas & Matsen classification, and two (8%) the Stanmore classification. CONCLUSIONS The FEDS classification system has not been embraced enough by the physical therapy scientific community since its publication in 2011.

Mil Med 2024; 189:384-390. [PMID: 37930763 DOI: 10.1093/milmed/usad413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 08/24/2023] [Accepted: 10/06/2023] [Indexed: 11/07/2023] Open
Abstract
Military service members (SMs) demonstrate high rates of patellofemoral chondral defects (PFCDs) that are difficult to diagnosis and, if untreated, result in a cascade of events eventually leading to osteoarthritis. Running is an essential occupational task for SMs; however, there is little evidence regarding techniques to maintain running ability in individuals with cartilage defects. The purpose of this case series was to assess the clinical application of foot strike run retraining in patients with PFCDs. This case series included two active duty U.S. Marine Corps SMs who presented to outpatient physical therapy with PFCD, diagnosed via MRI. Both patients attended eight foot strike run retraining sessions. Running mechanics and patient-reported outcomes were recorded pre-training, post-training, and at a 1-month follow-up visit. Both patients successfully converted their strike pattern from a rearfoot to a non-rearfoot strike pattern with training and retained this strategy at 1-month follow-up. Post-intervention, both patients demonstrated increased running tolerance, and improvements in Numeric Pain Rating Scale and Lower Extremity Functional Scale scores. Biomechanical analysis showed that both patients demonstrated a 63% to 70% reduction in average and peak vertical ground reaction force loading rates post-treatment. Modification of foot strike pattern from rear to non-rearfoot strike during running for individuals with PFCD can reduce the magnitude of impact loading, which potentially limits disease progression. These findings suggest that foot strike run retraining may be a feasible strategy to reduce pain and improve function in SMs with PFCD who are required to run for occupational responsibilities.

Abstract
Introduction Anterior shoulder instability results in labral and osseous glenoid injuries. With a large osseous defect, there is a risk of recurrent dislocation of the joint, and therefore the patient has to undergo surgical correction. An MRI evaluation of the patient helps to assess the soft tissue injury. Currently, the volumetric three-dimensional (3D) reconstructed CT image is the standard for measuring glenoid bone loss and the glenoid index. However, it has the disadvantage of exposing the patient to radiation and additional expenses. This study aims to compare the values of the glenoid index using MRI and CT. Methodology The present study was a two-year cross-sectional study of patients with shoulder pain, trauma, and dislocation in a tertiary hospital in Karnataka. The sagittal proton density (PD) section of the glenoid and enface 3D reconstructed images of the scapula were used to calculate glenoid bone loss and the glenoid index. The baseline data were analyzed using descriptive statistics, and the Chi-square test was used to test the association of various complications with selected variables of interest. Results The glenoid index calculated in the current study using 3D volumetric CT images and MR sagittal PD images was 0.95±0.01 and 0.95±0.01, respectively. The CT and MRI glenoid bone loss was 5.41±0.65% and 5.38±0.65%, respectively. When compared, the glenoid index and bone loss calculated by MRI and CT revealed a high correlation and significance with a p-value of <0.001. Conclusions The study concluded that MRI is a reliable method for glenoid measurement. The sagittal PD sequence combined with an enface glenoid makes it possible to identify osseous defects linked to glenohumeral joint damage and dislocation. The values derived from 3D CT are identical to the glenoid index and bone loss determined using the sagittal PD sequence in MRI.

ASSESSMENT OF THE LEVEL OF SATISFACTION OF PATIENTS SUBMITTED TO LATARJET SURGERY UNDER OUTFIT SYSTEM COMPARED TO HOSPITAL SYSTEM. ACTA ORTOPEDICA BRASILEIRA 2023; 31:e264837. [PMID: 37876869 PMCID: PMC10592333 DOI: 10.1590/1413-785220233105e264837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 08/19/2022] [Indexed: 10/26/2023]
Abstract
Anterior shoulder instability causes functional changes that affect patients' quality of life. The Latarjet procedure is one of the most frequently performed surgeries for cases of recurrent shoulder instability. Objective To assess the level of satisfaction of patients who underwent the Latarjet procedure in outpatient settings (day hospital) compared with inpatient settings. Methods A questionnaire was administered to both groups and a descriptive analysis of the results was performed. Results 51 patients were included, with a mean age of 29.9 years, 82.3% men and 17.6% women. Of the patients who underwent surgery in the day hospital, 46.1% were operated within 100 days of their first outpatient visit; among those in the inpatient group, 76.3% underwent surgery more than 200 days later. Delays occurred in 15.3% of cases in the day hospital compared with 68.4% in the inpatient group. Of the patients in the day hospital, 92.3% felt comfortable contacting the medical team in case of complications and would perform the procedure again in the same setting. Moreover, 63.2% of inpatients would have preferred to have been discharged on the same day. The final satisfaction rate for both groups was 100%. Conclusion Outpatient surgery guarantees more patient comfort, safety, and can be performed in a timely manner and with fewer delays, which has influenced patients' decision to have surgery during the COVID-19 pandemic.

Abstract
Background While there have been reliability studies conducted on several upper extremity functional performance tests (UEFPT), there are several complicating factors that inhibit the ability to draw definitive consensus about the reliability of the tests in both females and males. Having reliability estimates for UEFPT in the same cohort facilitates direct comparison of their relative and absolute reliability. Purpose To establish the test-retest reliability of the closed kinetic chain upper extremity stability test (CKCUEST), seated medicine ball chest pass test (SMBCPT) and hands-release push-up test (HRPUT) in a cohort of males and females with a history of non-overhead sport participation. A secondary purpose was to examine the associations between the three UEFPT. Study Design Test-retest reliability, single cohort study. Methods Forty adults (20 females, 20 males) with a history of non-overhead sport participation completed three UEFPT during two data collection sessions three to seven days apart. Measures of systematic bias, absolute reliability and relative reliability were computed between the sessions. Additionally, correlational analyses were conducted between the three UEFPT. Results Only the UECKCST (both sexes) demonstrated significant (p≤ 0.003) second session performance improvements. All three tests exhibited excellent relative reliability (intraclass correlational coefficients ≥ 0.823) and except for the HRPUT in males, coefficients of variation were all below 8.8%. Except for a significant relationship (r=.691, p=0.001) between the UECKCST and SMBCPT for the females there were no other associations between the three UEFPT. Conclusion All three UEFPT demonstrated sufficient reliability. Thus, all three assessments can be used for serial assessments to progress a patient through rehabilitation as well as contribute to the criteria used in making return to sport decisions.

Abstract
Background Arthroscopic repair of glenohumeral instability is becoming an increasingly common procedure. These repairs can be undertaken using knot-tying and knotless suture anchors; there is currently no clear consensus in the literature about what type of repair is most cost-effective and provides superior outcomes. The purpose of this study is to examine postoperative outcomes of patients undergoing arthroscopic anteroinferior labral repair (AALR) with either knot-tying or knotless anchors. Methods A single institution retrospective observational cohort study of 122 patients undergoing AALR from January 2014 to June 2021 was conducted. Univariate statistics were used to assess differences in demographics, operative characteristics, and postoperative outcomes between repair types; multivariate analysis was used to evaluate risk factors for recurrent instability and reoperation. Results Patients undergoing AALR with knotless anchors had a shorter case duration than those with knot-tying anchors (112.64 vs. 89.86 minutes, p<0.001). There were no significant differences between groups in the size of labral tear, presence of a glenoid bone defect, or Hill-Sachs lesion. After controlling for age, BMI, sex, glenoid bone defect, number of preoperative dislocations, and fixation type, only age (OR=0.896, p=0.010) and female sex (OR=5.341, p=0.008) were independent risk factors for recurrent instability and no factors were independent predictors of reoperation. Conclusion Patients undergoing AALR experienced similar rates of reoperation and recurrent instability regardless of whether a knot-tying or knotless repair was performed. The use of knotless suture anchors may improve cost-effectiveness due to decreased surgical time without diminishing postoperative outcomes.

Abstract
Background The Bodyblade™ has the potential of enhancing conservative management of Traumatic Anterior Shoulder Instability (TASI). Purpose The purpose of this study was to compare three different protocols: Traditional, Bodyblade™, and Mixed (Traditional & Bodyblade™) for shoulder rehabilitation on athletes with TASI. Study Design Randomized-controlled longitudinal training study. Methods Thirty-seven athletes (age = 19.9±2.0 years) were allocated into Traditional, Bodyblade™, and Mixed (Traditional/Bodyblade™) training groups (3×week for 8-weeks). The traditional group used resistance bands (10-15 repetitions). The Bodyblade™ group transitioned from classic to the pro model (30-60-s repetitions). The mixed group converted from the traditional (weeks 1-4) to the Bodyblade™ (weeks 5-8) protocol. Western Ontario Shoulder Index (WOSI) and the UQYBT were evaluated at baseline, mid-test, post-test, and at a three-month follow-up. A repeated-measures ANOVA design evaluated within and between-group differences. Results All three groups significantly (p=0.001, eta2: 0.496) exceeded WOSI baseline scores (at all timepoints) with training (Traditional: 45.6%, 59.4%, and 59.7%, Bodyblade™: 26.6%, 56.5%, and 58.4%, Mixed: 35.9%, 43.3% and 50.4% respectively). Additionally, there was a significant (p=0.001, eta2: 0.607) effect for time with mid-test, post-test and follow-up exceeding baseline scores by 35.2%, 53.2% and 43.7%, respectively. The Traditional and Bodyblade™ groups (p=0.049, eta2: 0.130) exceeded the Mixed group UQYBT at post-test (8.4%) and at three-month follow-up (19.6%). A main effect (p=0.03, eta2: 0.241) for time indicated that WOSI mid-test, post-test and follow-up exceeded the baseline scores by 4.3%, 6.3% and 5.3%. Conclusions All three training groups improved their scores on the WOSI. The Traditional and Bodyblade™ groups demonstrated significant improvements in UQYBT inferolateral reach scores at post-test and three-month follow-up compared to the Mixed group. These findings could lend further credibility to the role of the Bodyblade as an early to intermediate rehabilitation tool. LEVEL OF EVIDENCE 3.

Abstract
Shoulder instability is the separation of the humeral head from the glenoid. Injury to the static and dynamic stabilizers can result in instability. Anterior shoulder instability is the predominant form of instability. It is usually a result of trauma. Posterior shoulder instability often presents with an insidious onset of pain. Multidirectional instability of the shoulder is symptomatic laxity in more than one plane of motion. The primary goal of rehabilitation is to restore pain-free mobility, strength, and functioning. Rehabilitation implements range of motion and strengthening exercises to restore proprioceptive control and scapular kinematics.

Abstract
Luxatio erecta is an inferior glenohumeral dislocation. It is an uncommon pathology with a prevalence of 0.5% of all shoulder dislocations. An open luxatio erecta presentation is rarer. After an extensive literature search, we only could find three complete case reports. From these cases, 2 out of 3 developed complications such as infections and severely limited range of motion, especially in flexion and abduction. We report the case of a 39-year-old man with an open inferior glenohumeral joint dislocation with complete rotator cuff tear and fracture of the greater tuberosity secondary to a motor vehicle accident. He was treated with open reduction, glenohumeral capsulorrhaphy, and transosseous rotator cuff repair with good clinical outcome. In conclusion, an open inferior shoulder dislocation is rare, less than 0.1% of all dislocations, with a high incidence of nerve injury. We suggest prompt surgical treatment with immediate administration of antibiotic therapy, wound debridement, irrigation, open reduction, and repair of the rotator cuff as an adequate protocol and focused rehabilitation with early mobilization of the glenohumeral joint.

Abstract
Meniscal tearing in the knee increases the risk of post-traumatic osteoarthritis (OA) in patients. The therapeutic application of tissue-specific mesenchymal progenitor cells is currently being investigated as an emerging biologic strategy to help improve healing of musculoskeletal tissues like meniscal fibrocartilage and articular hyaline cartilage. However, many of these approaches involve isolating cells from healthy tissues, and the low yield of rare progenitor populations (< 1% of total cells residing in tissues) can make finding a readily available cell source for therapeutic use a significant logistical challenge. In the present study, we investigated the therapeutic efficacy of using expanded cartilage-derived and bone marrow-derived progenitor cell lines, which were stabilized using retroviral SV40, for repair of meniscus injury in a rodent model. Our findings indicate that these cell lines express the same cell surface marker phenotype of primary cells (CD54+, CD90+, CD105+, CD166+), and that they exhibit improved proliferative capacity that is suitable for extensive expansion. Skeletally mature male athymic rats treated with 3.2 million cartilage-derived progenitor cell line exhibited approximately 79% greater meniscal tear reintegration/healing, compared to injured animals that left untreated, and 76% greater compared to animals treated with the same number of marrow-derived stromal cells. Histological analysis of articular surfaces also showed that cartilage-derived progenitor cell line treated animals exhibited reduced post-traumatic OA associated articular cartilage degeneration. Stable cell line treatment did not cause tumor formation or off-target engraftment in animals. Taken together, we present a proof-of-concept study demonstrating, for the first time, that intra-articular injection of a stable human cartilage-derived progenitor cell line stimulates meniscus tear healing and provide chondroprotection in an animal model. These outcomes suggest that the use of stable cell lines may help overcome cell source limitations for cell-based medicine.

Abstract
PURPOSE To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes younger than 20 years old with a significant glenoid bone loss. METHODS Between 2010 and 2017, 60 competitive athletes younger than 20 years old with a significant glenoid bone loss were operated with the Latarjet procedure. Return to sports, range of motion, and the Rowe and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated. RESULTS The mean follow-up was 58 months and the mean age was 16.3 years. Overall, 93% were able to return to sports and 84% returned at the same level. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P < .001). The total complication rate was 22% and the revision rate was 1.6%. The recurrence rate was 3.3%. The bone block healed in 93% of the cases. CONCLUSIONS In competitive athletes younger than 20 years old with a significant glenoid bone loss, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences. However, this procedure is associated with a significant rate of complications and should preferably be performed by experienced surgeons.

Abstract
BACKGROUND While the glenoid track concept presents a useful prediction for recurrent glenohumeral instability, little is known about the humeral head bony architecture as it relates to glenoid erosion in the setting of bipolar bone loss. PURPOSE To (1) qualitatively and quantitatively analyze the interplay between glenoid bone loss (GBL) and Hill-Sachs lesions (HSLs) in a cohort of patients with anterior instability using 3-dimensional imaging software and (2) assess the relationships between GBL and HSL characteristics. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Patients were identified who had anterior shoulder instability with a minimum 5% GBL and evidence of HSL confirmed on computed tomography. Unilateral 3-dimensional models of the ipsilateral proximal humeral head and en face sagittal oblique view of the glenoid were reconstructed using MIMICS software (Materialise NV). GBL surface area, width, defect length, and glenoid track width were quantified. The volume, surface area, width, and depth of identified HSLs were quantified with their location (medial, superior, and inferior extent) on the humeral head. Severity of GBL was defined as percentage glenoid bone surface area loss and categorized as low grade (5%-10%), moderate grade (>10% to 20%), high grade (>20% to 30%), and extensive (>30%). Analysis of variance was then computed to determine significance (P < .05) between severity of GBL and associated HSL parameters. RESULTS In total, 100 patients met inclusion criteria (mean age, 27.9 years; range, 18-43 years), which included 58 right shoulders and 42 left shoulders (84 male, 16 female). Among groups, there were 32 patients with low-grade GBL (mean GBL = 6.1%), 38 with moderate grade (mean GBL = 16.2%), 17 with high grade (mean GBL = 23.7%), and 13 with extensive (mean GBL = 34.0%), with an overall mean GBL of 18.1% (range, 5%-39%). Patients with 5%-10% GBL had significantly narrower HSLs (average and maximum width; P < .03) and deeper HSLs (average depth; P = .002) as compared with all other GBL groups, while greater GBL was associated with wider and shallower HSLs. GBL width, percentage width loss, defect length, and glenoid track width all significantly differed across the 4 GBL groups (P < .05). CONCLUSION HSLs had significantly different morphological characteristics depending on the severity of GBL, indicating that GBL was directly related to the characteristics of HSLs. Patients presenting with smaller glenoid defects had significantly narrower and deeper HSLs with less humeral head surface area loss, while greater GBL was associated with wider and shallower HSLs.

Abstract
BACKGROUND No previous systematic reviews have reported on athletes who fail to return to sports after arthroscopic Bankart repair. PURPOSE To review the literature on athletes who fail to return to sports after arthroscopic Bankart repair to determine the rate of athletes who did not return to sports and to identify the specific reasons for failure to return to sports by nonreturning athletes. STUDY DESIGN Systematic review and meta-analysis. METHODS A meta-analysis was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Three electronic databases (PubMed, Scopus, Web of Science) were queried for articles meeting the inclusion criteria. Studies were considered eligible only if reporting the rate of failure for return to sports and providing the specific reasons why athletes were unable to return to sports. All records were screened by title, abstract, and full text by 2 authors independently, with any discrepancies resolved by a third senior author. For articles selected for inclusion, data were collected on the number of athletes, average age, average follow-up time, type of sport played, rate of failure to return to sports, and specific reasons for failure to return. A random-effects model was used to conduct the meta-analysis. RESULTS Seventeen studies were selected for inclusion reporting on a total of 813 athletes. The calculated weighted rate of failure to return to sports after arthroscopic Bankart repair was 15.6% (95% CI, 10.9%-21.1%). A significantly higher proportion of athletes cited shoulder-dependent versus shoulder-independent reasons for failure to return to sports (81.7% vs 18.3%; P < .0001). The most cited reasons for failure to return included recurrent or persistent instability (33.3%), fear of reinjury (17.7%), apprehension (9.9%), changes in priorities or personal interest (8.5%), lack of time (7.1%), and discomfort or pain with sports (6.4%). CONCLUSION Our study estimated the rate of failure to return to sports after arthroscopic Bankart repair to be 15.6%, with most athletes citing shoulder-related reasons as the primary factor precluding return. Identifying the potential reasons preventing successful return to sports can guide surgeons in counseling athletes regarding postoperative expectations and addressing hesitations for returning to sports.

Abstract
BACKGROUND Anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions can occur in recurrent anterior shoulder instability, which may lead to the labrum scarring medially to the glenoid. ALPSA lesions have also been associated with greater preoperative dislocations, larger Hill-Sachs lesions, and greater degrees of glenoid bone loss. Therefore, patients with these lesions have historically had a higher failure rate after repair, with nearly double the recurrent instability rate compared with those undergoing standard arthroscopic Bankart repair. PURPOSE To compare minimum 2-year outcomes of arthroscopic mobilization and anatomic repair of ALPSA lesions with those after standard arthroscopic Bankart repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Consecutive patients who underwent arthroscopic repair of ALPSA lesions were matched in a 1-to-3 fashion to patients who underwent standard Bankart repair by age, sex, number of previous ipsilateral shoulder instability surgical procedures, and number of anchors used. Patient-reported outcome (PRO) scores were compared preoperatively and postoperatively (American Shoulder and Elbow Surgeons [ASES]; 12-Item Short Form Health Survey [SF-12] Physical Component Summary [PCS]; Single Assessment Numeric Evaluation [SANE]; shortened version of Disabilities of the Arm, Shoulder and Hand; and satisfaction). Recurrent instability, on- versus off-track Hill-Sachs lesion, and reoperation rates were analyzed. RESULTS A total of 100 shoulders (25 ALPSA and 75 Bankart) with an overall mean age of 25.7 years were evaluated. Patients in the ALPSA group demonstrated significant improvements in the ASES (preoperative, 74.8; postoperative, 89.7; P = .041) and SF-12 PCS (preoperative, 46.9; postoperative, 53.4; P = .021) scores but not the SANE score (preoperative, 65.2; postoperative, 75.3; P = .311). Patients in the Bankart group had significant improvements in all outcome scores at final follow-up: ASES (preoperative, 67.1; postoperative, 90.3), SANE (preoperative, 58.0; postoperative, 85.7), and SF-12 PCS (preoperative, 45.3; postoperative, 52.9) (all P < .001). There were no significant differences in PRO scores between the groups preoperatively or postoperatively (P > .05). The median satisfaction for the ALPSA group was 10 of 10 and for the Bankart group it was 9 of 10 (P = .094). There was a significantly higher rate of recurrent dislocation in the ALPSA group (8/25 [32.0%]) compared with the Bankart group (10/75 [13.3%]) (P = .040). Additionally, 5 patients (20.0%) in the ALPSA group underwent revision surgery at a mean of 5.6 years, and 8 patients (10.7%) in the Bankart group underwent revision surgery at a mean of 4.4 years (P = .311). CONCLUSION Despite improvements in the recognition of and surgical techniques for ALPSA lesions, they still lead to significantly higher postoperative dislocation rates; however, no differences in PRO scores were found. These findings highlight the importance of early surgical interventions in anterior shoulder instability with the hope of lessening recurrent instability and the risk of developing an ALPSA lesion, as well as careful assessment of the quality of soft tissues and other risk factors for recurrence when considering what type of shoulder stabilization procedure to perform.

Abstract
PURPOSE The treatment of anterior shoulder instability is a focus in the field of sports medicine. While much research has been conducted, few bibliometric studies have been performed in this field. This study analyzed the main characteristics and identified emerging research trends and hotspots related to the treatment of anterior shoulder instability over the past four decades. METHODS We searched for (anterior shoulder instability OR anterior shoulder dislocation) AND (treatment OR reconstruction) in ARTICLE (Mesh) in the Web of Science database from 1980 to 2020. We analyzed the keywords, author, institution, country, number of citations, average number of citations, publication year, and partnership of the identified articles. Information about annual publications was analyzed using Microsoft Excel 2019; the remaining data were analyzed using VOSviewer version 1.6.11 (Leiden University, Leiden, Netherlands) and CiteSpace version 5.7.R2 (Drexel University, Philadelphia, PA, USA). RESULTS A total of 1964 articles were published between 1980 and 2020. The American Journal of Sports Medicine, the United States, the United States Department of Defense, and Arcieio were journals, countries, institutions, and authors with the highest numbers of publications. The topic hotspots were instability, shoulder, and dislocation, while the research frontiers were arthroscopic, Bankart repair, Latarjet procedure, risk factors, recurrence, and complications. CONCLUSION The treatment of anterior shoulder instability has shown an increasing number of publications each year and achieved great progress. The United States made the most outstanding contributions to this important field. Arthroscopic, Bankart repair, and Latarjet procedures were research hotspots and risk factors, recurrence, and complications were likely to research frontiers.

Long-term results after posterior open glenoid wedge osteotomy for posterior shoulder instability associated with excessive glenoid retroversion. J Shoulder Elbow Surg 2022; 31:81-89. [PMID: 34216782 DOI: 10.1016/j.jse.2021.05.028] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 05/26/2021] [Accepted: 05/30/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Treatment of posterior shoulder instability (PSI) associated with excessive glenoid retroversion is a rare, challenging problem in shoulder surgery. One proposed technique is posterior open wedge glenoid osteotomy to correct excessive glenoid retroversion as described by Scott. However, this operation is rarely performed, and limited long-term outcomes using this approach are available. The goal of this study was to analyze the long-term outcomes of posterior open wedge glenoid osteotomy for PSI associated with excessive glenoid retroversion. METHODS Six consecutive patients (7 shoulders) with a mean age of 24 years (range 19-34) were treated with posterior open wedge glenoid osteotomy for PSI associated with a glenoid retroversion greater than 15° and followed up clinically and radiographically at a mean age of 15 years (range 10-19). RESULTS Recurrent, symptomatic PSI was observed in 6 of 7 shoulders (86%). One necessitated revision with a posterior (iliac crest) bone block procedure and was rated as a failure and excluded from functional analysis. One patient rated his result as excellent, 3 as good, 1 as fair, and 1 as unsatisfactory. Mean relative Constant Score (CS%) was unchanged from preoperation to final follow-up (CS% = 72%) and pain did not significantly decrease (Constant Score = 7-10 points; P = .969). The mean Subjective Shoulder Value (SSV) improved postoperatively, but with 6 patients the improvement did not reach statistical significance (SSV = 42%-67%, P = .053) and the total Western Ontario Shoulder Instability Index averaged 30% at the final follow-up. Mean glenoid retroversion of all 7 shoulders was corrected from 20° (range 16°-26°) to 3° (range -3° to +8°) (P = .018). In the 5 shoulders with preoperative static posterior subluxation of the humeral head, the humeral head was not recentered. All 7 shoulders showed progression of glenoid arthritic changes. CONCLUSIONS Posterior open wedge glenoid osteotomy for PSI associated with excessive glenoid retroversion neither reliably restored shoulder stability nor recentered the joint or prevent progression of osteoarthritis. Alternative treatments for PSI associated with excessive glenoid retroversion have to be developed and evaluated.

Abstract
Background Few studies have compared conventional and self-assisted shoulder reduction maneuvers. The goal of this study was to evaluate the results of self-assisted Davos vs. traction/countertraction (T/Ct) techniques in the treatment of acute anterior shoulder dislocations. Methods This was a single-center, prospective study carried out at a tertiary hospital emergency department. Patients aged 18-69 years old, with radiographic confirmation of anterior glenohumeral dislocations, were consecutively allocated to treatment groups. Recorded data included pain at admission (visual analog scale [VAS] score at admission), analgesia before reduction, maximum pain during reduction (maximum VAS score), demographic characteristics, lesion mechanism, laterality, prior dislocation, and immediate complications. The primary outcomes were reduction success rate and pain. Results Eighty individuals were included (40/group). Regarding the success rate, no statistically significant differences were found between Davos or T/Ct (87.5% vs. 85%; P = .058). The maximum VAS score was significantly lower in Davos than that in T/Ct (4.18 ± 2.00 vs. 6.30 ± 2.13; P < .001). The effect of analgesia in the maximum VAS score was more evident among Davos patients, with significantly lower pain in the subgroup who were provided analgesia (3.63 ± 2.02 vs. 5.31 ± 2.01; P = .01). Discussion Davos was as effective as T/Ct for reduction of acute anterior shoulder dislocations (highest reported success rate: 87.5%) and conditioned a less traumatic experience, with significantly lower pain during reduction (the maximum VAS score was more than 2 points lower in the Davos group; P < .001). Analgesia had a synergistic effect among patients submitted to the Davos technique, suggesting that T/Ct is inherently more painful. Conclusion The Davos is a patient-controlled, atraumatic, and safe technique, allowing successful, gentle, and less painful glenohumeral reduction. These findings favor Davos as an easy-to-teach and effective first-line treatment for first-time and recurrent shoulder dislocations.

Abstract
INTRODUCTION Recent epidemiological evidence shows that shoulder and upper-arm complaints impose a substantial burden on the armed forces of the United States and create significant challenges for all components of the physical fitness domain of total force fitness. Clinicians, epidemiologists, and health-services researchers interested in shoulder and upper-arm injuries and their functional limitations rarely have objective, validated criteria for rigorously evaluating diagnostic practices, prescribed treatments, or the outcomes of alternative approaches. We sought to establish and quantify patient volume, types of care, and costs within the Military Health System (MHS) in assessing and managing active duty members with nonoperative shoulder and upper-arm dysfunction. MATERIALS AND METHODS We performed a retrospective cohort study using data from the MHS Data Repository and MHS MART (M2) from fiscal year 2014 to identify active duty individuals with a diagnosis of shoulder and upper-arm injury or impairment defined by one of the International Classification of Disease Ninth Edition diagnosis codes that were selected to reflect nonoperative conditions such as fractures or infections. Statistical analyses include descriptive statistics on patient demographics and clinical visits, such as the range and frequency of diagnoses, number and types of appointments, and clinical procedure information following the diagnosis. We also examined treatment costs related to shoulder dysfunction and calculated the total cost to include medications, radiological, procedural, and laboratory test costs for all shoulder dysfunction visits in 2014 and the average cost for each visit. We further examined the category of each medication prescribed. RESULTS A total of 55,643 individuals met study criteria and accrued 193,455 shoulder-dysfunction-related clinical visits in fiscal year 2014. This cohort represents approximately 4.8% of the 1,155,183 active duty service members assigned to the United States and its territories during FY 2014. Most patients were male (85.32%), younger (85.25% were under 40 years old), and Caucasian/White (71.12%). The most common diagnosis code was 719.41 (pain in joint, shoulder region; 42.48%). The majority of the patients 42,750 (76.8%) had four or fewer medical visits during the study period and 12,893 (23.2%) had more than four visits. A total of 4,733 patients (8.5%) underwent arthrocentesis aspiration or injection. The total cost for all visits was $65,066,767.89. The average and median cost for each visit were $336.34 (standard deviation was $1,493.87) and $163.11 (range was from 0 to $84,183.88), respectively. Three out of four patients (75.3%) underwent radiological examinations, and 74.2% of these individuals had more than one radiological examination. Medications were prescribed to 50,610 (91.0%) patients with the three most common being IBUPROFEN (12.21%), NAPROXEN (8.51%), and OXYCODONE-ACETAMINOPHEN (5.04%), respectively. CONCLUSIONS Nearly 1 in 20 active duty military service members presented for nonoperative care of shoulder and/or upper-arm dysfunction during FY2014. Further examinations of the etiology and potential impact of shoulder/upper-arm dysfunction on force readiness are clearly warranted, as are additional studies directed at identifying best practices for preventing injury-related dysfunction and determining best practices for the treatment of shoulder dysfunction to optimize service member fitness and force readiness.

Abstract
Background: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. Purpose: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We included studies published between January 1990 and October 2020 that described clinical outcomes of the traditional Latarjet and the congruent arc modification with a follow-up range of 2 to 10 years. The difference in surgical technique was analyzed using a chi-square test for categorical variables, while continuous variables were evaluated using a Student t test. Results: In total, 26 studies met the inclusion criteria: 20 studies describing the traditional Latarjet procedure in 1412 shoulders, and 6 studies describing the congruent arc modification in 289 shoulders. No difference between procedures was found regarding patient age at surgery, follow-up time, Rowe or postoperative visual analog scores, early or late complications, return-to-sport timing, or incidence of improper graft placement or graft fracture. A significantly greater proportion of male patients underwent glenoid augmentation using the congruent arc modification versus traditional Latarjet (P < .001). When comparing outcomes, the traditional Latarjet procedure demonstrated a lower incidence of fibrous union or nonunion (P = .047) and broken, loose, or improperly placed screws (P < .001), and the congruent arc modification demonstrated improved outcomes with regard to overall return to sport (P < .001), return to sport at the same level (P < .001), incidence of subluxation (P = .003) or positive apprehension (P = .002), and revision surgery for recurrent instability (P = .027). Conclusion: Outcomes after the congruent arc modification proved at least equivalent to the traditional Latarjet procedure in terms of recurrent instability and return to sport, although early and late complications were equivalent. The congruent arc procedure may be an acceptable alternative to traditional Latarjet for the treatment of anterior shoulder instability with glenoid bone loss; however, long-term outcomes of this procedure are needed.

Abstract
The glenohumeral joint is intrinsically predisposed to instability because of the bony anatomy but maintained in alignment by many important structures, including the glenoid labrum, glenohumeral ligaments (GHLs), and muscles and tendons. Trauma and overuse can damage these stabilizers, which may then lead to subluxation or dislocation and eventually recurrent instability. This is most common in the anterior direction, which has several recognizable patterns of injury on advanced imaging, including humeral Hill Sachs deformities, bony Bankart lesion of the anteroinferior glenoid, soft tissue Bankart lesions, Bankart variant lesions (Perthes and ALPSA lesions), and HAGL/GAGL lesions. Similar reverse lesions are seen, as well as unique posterior lesions, such as Bennett and Kim's lesions. When symptoms of apprehension and instability in more than one direction are seen, one should consider multidirectional instability, which often presents with a patulous joint capsule. Finally, owing to significant impacts of daily activities and quality of life, surgical correction of labral tears, bony Bankart defects, Hill Sachs defects, and capsular laxity, may be considered.

Reasons Why Athletes Do Not Return to Sports After Arthroscopic Bankart Repair: A Comparative Study of 208 Athletes With Minimum 2-Year Follow-up. Orthop J Sports Med 2021; 9:23259671211013394. [PMID: 34368378 PMCID: PMC8299894 DOI: 10.1177/23259671211013394] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 01/21/2021] [Indexed: 11/25/2022] Open
Abstract
Background: There is a lack of information regarding the reasons why patients do not return to sports after an arthroscopic Bankart repair and whether there is a relationship between return to sports and functional outcomes. Purpose: To evaluate the reasons why competitive athletes who underwent arthroscopic Bankart repair did not return to sports and whether there was a relationship between returning to sports and postoperative outcome scores and complications. Study Design: Cohort study; Level of evidence, 3. Methods: Of 217 competitive athletes who underwent arthroscopic Bankart repair for isolated anterior glenohumeral instability between June 2014 and December 2017, a total of 208 athletes (96%) were evaluated at minimum 2-year follow-up. Return to sports, the level of sports achieved, and the time between surgery and return to competition were assessed, and patients who did not return to sports were asked to provide the reasons for cessation. The Rowe score and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences, reoperations, and complications were also evaluated. Results: The mean patient age was 24 years (range, 18-30 years), and the mean follow-up was 44 months (range, 24-90 months). Of the 208 athletes, 73% were able to return to sports (65% returned to their preinjury level), and 27% did not return to sports. Of those who did not return, the most frequent reasons were fear of reinjury (44%), lack of confidence in their shoulder (12%), and concern about a new rehabilitation process in case of recurrence (10%). The Rowe and ASOSS scores showed significant postoperative improvement in all patients (P < .001), with no significant differences between the 2 study groups at the final follow-up. There were 21 recurrences (10%) and 5 complications (2.4%), and 11 patients (5.3%) underwent revision surgery, with no significant differences in these rates between the groups. Conclusion: Of patients who did not return to sports, 74% left for a reason independent of shoulder function, with the most frequent causes being fear of reinjury and a concern about new rehabilitation process. Neither outcome scores nor complications varied significantly between patients who returned and those who did not return to sports.

Arthroscopic Bankart repair with all-suture anchors does not cause important glenoid bone osteolysis: a volumetric CT study of 143 anchors. Knee Surg Sports Traumatol Arthrosc 2021; 29:2152-2158.

Abstract
PURPOSE To evaluate with computed tomography (CT) the incidence of anchor-related osteolysis after implantation of two types of all-suture anchors for the management of labral lesions in shoulder instability. METHODS Single-cohort, observational study with 12-month follow-up. Thirty-three participants (27 males/6 females; age 38.3 years [SD 11.3]) with anterior labral lesions in which 143 all-suture anchors (71 Iconix 1.4 mm and 72 Suturefix 1.7 mm) were implanted were evaluated with a CT performed a mean of 15.4 [3.85] months after surgery. The volume of the bone defects was measured in the CT. Every anchor was classified into one of four groups: (1) no bone defect. (2) Partial bone defect (defects smaller than the drill used for anchor placement). (3) Tunnel enlargement (defects larger than the drill volume but smaller than twice that volume). (4) Cystic lesion (defects larger than twice the drill volume). RESULTS No bone defect was identified in 16 anchors (11.2%, [95% CI 6.5-17.5%]). A partial bone defect was found in 84 anchors (58.7% [50.2-66.9%]). Tunnel enlargement was found in 43 anchors (30.11% [22.6-37.6%]). No anchor caused cystic lesions (0% [0-2.5%]). The defect volume was a mean of 27.8 mm3 (SD 18.4 mm3, minimum 0 mm3, maximum 94 mm3). Neither the position in the glenoid nor the type of implant used had a significant effect in the type or size of the defects. CONCLUSION When using all-suture anchors in the glenoid during instability surgery, relevant bone osteolytic defects are rare at 1-year follow-up. Most anchor insertion tunnels will fill completely (11%) or partially (59%) with bone. Tunnel enlargement will develop in 30% of anchors. No cystic defects larger than 0.125 cm3 were observed. There is a low risk that all-suture anchors cause significant osteolytic bone defects in the glenoid. These implants can be used safely. Level of evidence IV.

Career Longevity and Performance After Shoulder Instability in National Football League Athletes. Arthroscopy 2021; 37:1437-1445. [PMID: 33422614 DOI: 10.1016/j.arthro.2020.12.225] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 12/15/2020] [Accepted: 12/20/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To investigate the career longevity, game utilization, and performance of National Football League (NFL) athletes after glenohumeral instability events treated operatively versus nonoperatively. METHODS Using public resources, we identified NFL players who sustained a shoulder instability event from September 2000 to February 2019. Players with prior shoulder instability, without NFL experience before injury, or who did not return to play (RTP) after injury were excluded. Demographic information, utilization (games and seasons), and season approximate value (SAV) statistics were recorded 1 year prior to injury and 3 years after RTP. Statistical analysis compared utilization and the SAV after RTP for athletes managed operatively versus nonoperatively. RESULTS We identified 97 NFL players who sustained their first instability event while playing in the NFL, 91 of whom returned to play (93.8%). Quarterbacks were significantly more likely to undergo immediate surgical management compared with players in other positions (P = .023). The final analysis included 58 players managed operatively and 33 managed nonoperatively by the end of the index season. Players treated operatively played in significantly more seasons after RTP during their remaining careers (4.1 ± 2.7 seasons vs 2.8 ± 2.5 seasons, P = .015). There were no differences in games played or started, offensive or defensive snap count percentage, or performance (SAV) before and after injury when compared between cohorts (P > .05). After surgical stabilization, time to RTP (36.62 ± 10.32 weeks vs 5.43 ± 12.33 weeks, P < .05) and time interval before recurrent instability (105.7 ± 100.1 weeks vs 24.7 ± 40.6 weeks, P < .001) were significantly longer than with nonoperative treatment. Additionally, the operative cohort experienced less recurrent instability (27% vs 50%, P = .035). CONCLUSIONS Athletes who RTP in the NFL after a shoulder instability injury do so with a similar workload and performance irrespective of surgical or nonsurgical management. Whereas nonoperative treatment is associated with faster RTP, operative management is associated with fewer recurrent instability events, greater time between recurrent instability events, and greater career longevity. LEVEL OF EVIDENCE Level III, retrospective case-control study.

Abstract
BACKGROUND Joint hypermobility in athletes is associated with increased risk of knee injuries, but its role in relation to shoulder injuries has not been scrutinized. Therefore, our aim was to synthesize the evidence on the association between joint hypermobility and shoulder injuries in athletes. METHODS Data sources were MEDLINE, CINAHL, EMBASE, and SPORTDiscus from inception to 27th February 2021. Eligibility criteria were observational studies of athletes (including military personnel), mean age ≥ 16 years, and with a transparent grouping of those with and without joint hypermobility. A broad definition of joint hypermobility as the exposure was accepted (i.e., generalised joint hypermobility (GJH), shoulder joint hypermobility including joint instability). Shoulder injuries included acute and overuse injuries, and self-reported pain was accepted as a proxy for shoulder injuries. The Odds Ratios (OR) for having shoulder injuries in exposed compared with non-exposed athletes were estimated using a random effects meta-analysis. Subgroup analyses were performed to explore the effect of sex, activity type, sports level, study type, risk of bias, and exposure definition. Risk of bias and the overall quality of evidence were assessed using, respectively, the Newcastle-Ottawa Scale and the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS Among 6207 records, six studies were included with 2335 (range 118-718) participants (34.1% females; athlete mean age 19.9 years). Athletes with joint hypermobility were more likely to have shoulder injuries compared with athletes without joint hypermobility (OR = 3.25, 95% CI 1.64, 6.43, I2 = 75.3%; p = 0.001). Exposure definition (GJH, OR = 1.97, 95% CI 1.32, 2.94; shoulder joint hypermobility, OR = 8.23, 95% CI 3.63, 18.66; p = 0.002) and risk of bias (low, OR = 5.25, 95% CI 2.56, 10.8; high, OR = 1.6, 95% CI 0.78, 3.29; p = 0.024) had large impacts on estimates, while the remaining subgroup analyses showed no differences. The overall quality of evidence was low. CONCLUSION Joint hypermobility in athletes is associated with a threefold higher odds of having shoulder injuries, highlighting the need for prevention strategies in this population. However, due to low quality of evidence, future research will likely change the estimated strength of the association. PROTOCOL REGISTRATION Open Science Framework registration osf.io/3wrn9.

Abstract
BACKGROUND Treatment of first-time shoulder dislocation (FSD) is a topic of debate. After high rates of recurrent instability after nonoperative management were reported in the literature, primary repair of FSD significantly increased. At the same time, new concepts were proposed that had promising results for immobilization in external rotation (ER) and abduction (ABD). PURPOSE The aim of this study was to evaluate the recurrence rates (primary outcome) and clinical outcomes (secondary outcome parameters) of immobilization in ER+ABD versus arthroscopic primary stabilization after FSD. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS In a multicenter randomized controlled trial, patients with FSD were randomized to either treatment with immobilization in 60° of ER plus 30° of ABD (group 1) or surgical treatment with arthroscopic Bankart repair (group 2). Clinical evaluation was performed 1, 3, and 6 weeks as well as 6, 12, and 24 months postoperatively or after reduction, including range of motion, instability testing, subjective shoulder value, Constant-Murley score, Rowe score, and Western Ontario Shoulder Instability Index. Recurrent instability events were prospectively recorded. RESULTS Between 2011 and 2017, a total of 112 patients were included in this study. Of these, 60 patients were allocated to group 1 and 52 to group 2. At the 24-month follow-up, 91 patients (81.3%) were available for clinical examination. The recurrence rate was 19.1% in group 1 and 2.3% in group 2 (P = .016). No significant differences were found between groups regarding clinical shoulder scores (P > .05). Due to noncompliance with the immobilization treatment protocol, 4 patients (6.7%) were excluded. CONCLUSION Immobilization in ER+ABD versus primary arthroscopic shoulder stabilization for the treatment of FSD showed no differences in clinical shoulder scores. However, recurrent instability was significantly higher after nonoperative treatment.

Abstract
Purpose To report the annual incidence of anterior shoulder instability (ASI) diagnosis, injury severity, and surgical stabilization in a U.S. population. Methods An established U.S. geographic database was used to identify patients < 40 years old with diagnoses of ASI from 1994-2016. Medical records were reviewed to obtain patient demographics, histories, imaging results, and surgical details. Age- and sex-specific incidence rates were calculated and adjusted to the 2010 U.S. population. Poisson regression was performed to examine trends by timeline, sex and age. Results The study population consisted of 652 patients with ASI and a mean age of 21.5 years (range, 3.6-39.5). Comparing 2015-2016 to 1994-1999, we found an increase in the number of dislocations (from 1.0-1.9; P = 0.016) and total instability events (from 2.3-3.4; P = 0.041) per patient prior to presentation to a physician. There was a trend in increased diagnosis of bony Bankart and/or Hill-Sachs on MRI over time, with these lesions documented in 96% of patients undergoing MRI in 2015-2018 compared to 52.9% in 1994-1999 (P < .001). The use of arthroscopic procedures increased and peaked in 2005-2009 (90% of surgical cases performed). The proportion of open Latarjet procedures increased from 2010-2014 (14%) and 2015-2018 (31%). Conclusions The age- and sex- adjusted incidence of ASI diagnosis in a U.S. population from 1994-2016 is comparable to that demonstrated in Canadian and European populations. This study demonstrates an increasing number of instability events prior to surgical evaluation, which may correlate with patients’ more commonly presenting with bone loss and requiring more aggressive surgical treatment or that ASI is being more frequently cared for and documented by present-day orthopedic surgeons.

Abstract
INTRODUCTION There is a large incidence of shoulder instability among active young athletes and military personnel. Shoulder stabilization surgery is the commonly employed intervention for treating individuals with instability. Following surgery, a substantial proportion of individuals experience acute post-operative pain, which is usually managed with opioid pain medications. Unfortunately, the extended use of opioid medications can have adverse effects that impair function and reduce military operational readiness, but there are currently few alternatives. However, battlefield acupuncture (BFA) is a minimally invasive therapy demonstrating promise as a non-pharmaceutical intervention for managing acute post-operative pain. METHODS This is a parallel, two-arm, single-blind randomized clinical trial. The two independent variables are intervention (2 levels, standard physical therapy and standard physical therapy plus battlefield acupuncture) and time (5 levels, 24 h, 48 h, 72 h, 1 week, and 4 weeks post shoulder stabilization surgery). The primary dependent variables are worst and average pain as measured on the visual analog scale. Secondary outcomes include medication usage, Profile of Mood States, and Global Rating of Change. DISCUSSION The magnitude of the effect of BFA is uncertain; current studies report confidence intervals of between-group differences that include minimal clinically important differences between intervention and control groups. The results of this study may help determine if BFA is an effective adjunct to physical therapy in reducing pain and opioid usage in acute pain conditions.

INTRODUCTION Recurrence rates after primary traumatic shoulder dislocation are distinctly high. Whether the early external immobilization (ER) is better than the internal immobilization (IR) is still controversial. HYPOTHESIS To perform a systematic review of randomized clinical trials (RCTs) that assessed the ability of external immobilization to reduce the recurrence in patients with primary anterior shoulder instability. MATERIAL AND METHOD As with the original review, we used the search strategies recommended by the Cochrane Back Review Group for the identification of RCTs. Thirteen RCTs were included in the systematic review, and 11 studies were included in the quantitative synthesis. RESULT A total of 1042 participants with primary shoulder dislocation were involved. The meta-analysis of 11 trials revealed that ER therapy leading to less recurrence rates than participants treated with IR therapy (RR=0.55; 95%CI: 0.36 to 0.82; Z=2.88; p=0.004), and less complications (RR=0.6; 95%CI: 0.39 to 0.92; Z=2.33; p=0.02) from the 5 independent trials. The meta-analysis of three trials revealed that there are not statistically significant in compliance rate (RR=1.08; 95%CI: 0.89 to 1.29; Z=0.78; p=0.44). The GRADE level of evidence is high for adverse events, but moderate for recurrence rate and Compliance rate. The Begg test showed that no significant publication bias was detected (p=0.062). DISCUSSION This meta-analysis suggests that external immobilization is recommended to reduce the recurrence rate and prevent complications. LEVEL OF PROOF II, low-powered systematic review and meta-analysis (systematic review, meta-analysis).

Abstract
Background Management of bone loss in recurrent traumatic anterior shoulder instability remains a topic of debate and controversy in the orthopedic community. The purpose of this study was to survey members of 4 North American orthopedic surgeon associations to assess management trends for bone loss in recurrent anterior shoulder instability. Methods An online survey was distributed to all members of the American Shoulder and Elbow Surgeons, American Orthopaedic Society for Sports Medicine, and Canadian Orthopaedic Association and to fellow members of the Arthroscopy Association of North America. The survey comprised 3 sections assessing the demographic characteristics of survey respondents, the influence of prognostic factors on surgical decision making, and the operative management of 12 clinical case scenarios of varying bone loss that may be encountered in clinical practice. Results A total of 150 survey responses were returned. The age of the patient and quantity of bone loss were consistently considered important prognostic criteria. However, little consensus was reached for critical thresholds of bone loss and how this affected the timing (ie, primary or revision surgery) and type of bony augmentation procedure to be performed once a critical threshold was reached, especially in the context of critical humeral and bipolar bone loss. Conclusions Consistent trends were found for the management of recurrent anterior shoulder instability in cases in which no bone loss existed and when isolated critical glenoid bone loss was present. However, inconsistencies were observed when isolated critical humeral bone loss and bipolar bone loss were present.

Abstract
Most first-time anterior glenohumeral dislocations occur as the result of trauma. Many patients suffer recurrent episodes of anterior shoulder instability (ASI). The anatomy and biomechanics of ASI is addressed, as is the pathophysiology of capsulolabral injury. The roles of imaging modalities are described, including computed tomography (CT) and MR imaging with the additional value of arthrography and specialized imaging positions. Advances in 3D CT and MR imaging particularly with respect to the quantification of humeral and glenoid bone loss is discussed. The concepts of engaging and nonengaging lesions as well as on-track and off-track lesions are examined.

Abstract
BACKGROUND Patients who have undergone shoulder instability surgery are often allowed to return to sports, work, and high-level activity based largely on a time-based criterion of 6 months postoperatively. However, some believe that advancing activity after surgery should be dependent on the return of strength and range of motion (ROM). HYPOTHESIS There will be a significant loss of strength or ROM at 6 months after arthroscopic Bankart repair with remplissage compared with Bankart repair alone. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A total of 38 patients in a prospective multicenter study underwent arthroscopic Bankart repair with remplissage (33 males, 5 females; mean age, 27.0 ± 10.2 years; 82% with ≥2 dislocation events in the past year). Strength and ROM were assessed preoperatively and at 6 months after surgery. Results were compared with 104 matched patients who had undergone Bankart repair without remplissage, although all had radiographic evidence of a Hill-Sachs defect. RESULTS At 6 months, there were no patients in the remplissage group with anterior apprehension on physical examination. However, 26% had a ≥20° external rotation (ER) deficit with the elbow at the side, 42% had a ≥20° ER deficit with the elbow at 90° of abduction, and 5% had persistent weakness. Compared with matched patients who underwent only arthroscopic Bankart repair, the remplissage group had greater humeral bone loss and had a greater likelihood of a ≥20° ER deficit with the elbow at 90° of abduction (P = .004). Risk factors for a ≥20° ER deficit with the elbow at 90° of abduction were preoperative stiffness in the same plane (P = .02), while risk factors for a ≥20° ER deficit with the elbow at the side were increased number of inferior quadrant glenoid anchors (P = .003), increased patient age (P = .02), and preoperative side-to-side deficits in ER (P = .04). The only risk factor for postoperative ER weakness was preoperative ER weakness (P = .04), with no association with remplissage (P = .26). CONCLUSION Arthroscopic Bankart repair with remplissage did not result in significant strength deficits but increased the risk of ER stiffness in abduction compared with Bankart repair without remplissage at short-term follow-up.

Abstract
BACKGROUND There exists little nationwide data regarding fracture and dislocation patterns across a wide variety of sporting activities for all ages and sexes. HYPOTHESIS Participant demographics (age and sex) will vary with regard to fracture and joint dislocation sustained during sport-related activities. STUDY DESIGN Descriptive epidemiology study. LEVEL OF EVIDENCE Level 3. METHODS The National Electronic Injury Surveillance System All Injury Program data 2005 through 2013 were accessed; 18 common sports and recreational activities in the United States were selected. Statistical software was used to calculate the numbers of fractures and dislocations, and incidence was calculated using US Census Bureau data. Multivariate logistic regression analysis determined the odds ratios (ORs) for the occurrence of a fracture or dislocation. RESULTS A fracture occurred in 20.6% and a joint dislocation in 3.6% of the emergency department visits for sports-related injuries; annual emergency department visit incidence was 1.51 for fractures and 0.27 for dislocations (per 1000 people). Most of the fractures occurred in football (22.5%). The OR for fracture was highest for inline skating (OR, 6.03), males (OR, 1.21), Asians, whites, and Amerindians compared with blacks (OR, 1.46, 1.25, and 1.18, respectively), and those older than 84 years (OR, 4.77). Most of the dislocations occurred in basketball (25.7%). The OR for dislocation was highest in gymnastics (OR, 4.08), males (OR, 1.50), Asians (OR, 1.75), and in those aged 20 to 24 years (OR, 9.04). The most common fracture involved the finger, and the most common dislocation involved the shoulder. CONCLUSION Inline skating had the greatest risk for fracture, and gymnastics had the greatest risk for joint dislocation. CLINICAL RELEVANCE This comprehensive study of the risks of sustaining a fracture or dislocation from common sports activities across all age groups can aid sports health providers in a better understanding of those sports at high risk and be proactive in prevention mechanisms (protective gear, body training).

Abstract
Introduction Military personnel are at an increased risk of shoulder injuries due to training and deployment demands, however, there is a lack of information on the tactical athlete's upper extremity profile. Therefore, the purpose of this study was to examine shoulder musculoskeletal characteristics, including range of motion (ROM), strength, and function, and the relationships between these measures in Marine Corps Forces Special Operations Command (MARSOC) personnel without history of shoulder injury. Materials and Methods Participants included 195 full-duty male MARSOC personnel (age: 25.38 ± 2.85 yr; height: 1.79 ± 0.06 m, mass: 82.79 ± 7.88 kg) without history of shoulder injury. Measurements of ROM, strength, and function were obtained bilaterally. Shoulder internal rotation (IR) and external rotation (ER) ROM were summed to calculate total arc of motion (ARC). Shoulder IR and ER strength were assessed using an isokinetic dynamometer. Function was evaluated with an explosive push-up. Results MARSOC personnel present with significantly increased ER ROM, and decreased IR ROM and ARC in their dominant shoulder. They demonstrated greater IR strength and peak force during the explosive push-up on the dominant side but no bilateral differences in average or peak rate were found. Correlation analyses suggest a weak inverse relationship between strength and ARC (r = -0.15 to -0.24). Positive relationships between strength and function were identified except for dominant IR strength and push-up variables. Those with the greatest ARC demonstrated significantly weaker IR and ER strength compared to those with less motion. Conclusions MARSOC personnel demonstrate shoulder ROM and strength symmetry patterns similar to overhead athletes. Increased dominant shoulder strength does appear to translate to a bilateral functional performance, but overall performance may be limited by the weaker nondominant upper extremity. As ARC increases, IR and ER rotation strength decrease. Repetitive, increased loading of the dominant shoulder during functional movements and training may increase risk of chronic, overuse-type injuries, common to the military. Unilateral exercises and movement analysis should be incorporated to encourage proper development of bilateral shoulder strength, which may be particularly important in those with high ranges of ARC.

Abstract
BACKGROUND Acute anterior shoulder dislocation, which is the most common type of dislocation, usually results from an injury. Subsequently, the shoulder is less stable and is more susceptible to re-dislocation or recurrent instability (e.g. subluxation), especially in active young adults. After closed reduction, most of these injuries are treated with immobilisation of the injured arm in a sling or brace for a few weeks, followed by exercises. This is an update of a Cochrane Review first published in 2006 and last updated in 2014. OBJECTIVES To assess the effects (benefits and harms) of conservative interventions after closed reduction of traumatic anterior dislocation of the shoulder. These might include immobilisation, rehabilitative interventions or both. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, PEDro and trial registries. We also searched conference proceedings and reference lists of included studies. Date of last search: May 2018. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials comparing conservative interventions with no treatment, a different intervention or a variant of the intervention (e.g. a different duration) for treating people after closed reduction of a primary traumatic anterior shoulder dislocation. Inclusion was regardless of age, sex or mechanism of injury. Primary outcomes were re-dislocation, patient-reported shoulder instability measures and return to pre-injury activities. Secondary outcomes included participant satisfaction, health-related quality of life, any instability and adverse events. DATA COLLECTION AND ANALYSIS Both review authors independently selected studies, assessed risk of bias and extracted data. We contacted study authors for additional information. We pooled results of comparable groups of studies. We assessed risk of bias with the Cochrane 'Risk of bias' tool and the quality of the evidence with the GRADE approach. MAIN RESULTS We included seven trials (six randomised controlled trials and one quasi-randomised controlled trial) with 704 participants; three of these trials (234 participants) are new to this update. The mean age across the trials was 29 years (range 12 to 90 years), and 82% of the participants were male. All trials compared immobilisation in external rotation (with or without an additional abduction component) versus internal rotation (the traditional method) following closed reduction. No trial evaluated any other interventions or comparisons, such as rehabilitation. All trials provided data for a follow-up of one year or longer; the commonest length was two years or longer.All trials were at some risk of bias, commonly performance and detection biases given the lack of blinding. Two trials were at high risk of selection bias and some trials were affected by attrition bias for some outcomes. We rated the certainty of the evidence as very low for all outcomes.We are uncertain whether immobilisation in external rotation makes a difference to the risk of re-dislocation after 12 months' or longer follow-up compared with immobilisation in internal rotation (55/245 versus 73/243; risk ratio (RR) 0.67, 95% confidence interval (CI) 0.38 to 1.19; 488 participants; 6 studies; I² = 61%; very low certainty evidence). In a moderate-risk population with an illustrative risk of 312 per 1000 people experiencing a dislocation in the internal rotation group, this equates to 103 fewer (95% CI 194 fewer to 60 more) re-dislocations after immobilisation in external rotation. Thus this result covers the possibility of a benefit for each intervention.Individually, the four studies (380 participants) reporting on validated patient-reported outcome measures for shoulder instability at a minimum of 12 months' follow-up found no evidence of a clinically important difference between the two interventions.We are uncertain of the relative effects of the two methods of immobilisation on resumption of pre-injury activities or sports. One study (169 participants) found no evidence of a difference between interventions in the return to pre-injury activity of the affected arm. Two studies (135 participants) found greater return to sports in the external rotation group in a subgroup of participants who had sustained their injury during sports activities.None of the trials reported on participant satisfaction or health-related quality of life.We are uncertain whether there is a difference between the two interventions in the number of participants experiencing instability, defined as either re-dislocation or subluxation (RR 0.84, 95% CI 0.62 to 1.14; 395 participants, 3 studies; very low certainty evidence).Data on adverse events were collected only in an ad hoc way in the seven studies. Reported "transient and resolved adverse events" were nine cases of shoulder stiffness or rigidity in the external rotation group and two cases of axillary rash in the internal rotation group. There were three "important" adverse events: hyperaesthesia and moderate hand pain; eighth cervical dermatome paraesthesia; and major movement restriction between 6 and 12 months. It was unclear to what extent these three events could be attributed to the treatment. AUTHORS' CONCLUSIONS The available evidence from randomised trials is limited to that comparing immobilisation in external versus internal rotation. Overall, the evidence is insufficient to draw firm conclusions about whether immobilisation in external rotation confers any benefit over immobilisation in internal rotation.Considering that there are several unpublished and ongoing trials evaluating immobilisation in external versus internal rotation, the main priority for research on this question consists of the publication of completed trials and the completion and publication of ongoing trials. Meanwhile, evaluation of other interventions, including rehabilitation, is warranted. There is a need for sufficiently large, good-quality, well-reported randomised controlled trials with long-term follow-up. Future research should aim to determine the optimal immobilisation duration, precise indications for immobilisation, optimal rehabilitation interventions, and the acceptability of these different interventions.

Abstract
BACKGROUND Anatomic skeletal features of the shoulder play important roles in anterior shoulder dislocation. However, studies on the effect of the humeral structure are few. This case-control study aimed to analyze the risk factors of anterior shoulder instability, including glenoid and humeral factors. METHODS Anterior shoulder instability was found in 64 of 10,035 individuals who underwent magnetic resonance imaging. Propensity score matching was used to select controls matched for age, sex, height, and weight. We analyzed the glenoid and humeral structural data using conditional logistic regression analysis and identified cutoff points using receiver operating characteristic curve analysis. RESULTS Significant differences were found between the control and dislocation groups in the depth-to-width ratio (0.119 ± 0.034 vs. 0.105 ± 0.037, P = .021), height-to-width ratio (1.51 ± 0.13 vs. 1.67 ± 0.16, P < .001), humeral head diameter-to-glenoid fossa diameter ratio (1.56 ± 0.11 vs. 1.64 ± 0.20, P < .001), and humeral containing angle (67.3° ± 5.9° vs. 60.4° ± 5.9°, P < .001). The humeral containing angle (odds ratio, 0.95; P = .024) and the glenoid height-to-width ratio (odds ratio, 7.88; P = .002), adjusted for the depth-to-width ratio and diameter ratio, were associated with anterior shoulder instability. The cutoff point for the humeral containing angle was 64° and for the height-to-width ratio was 1.60. CONCLUSIONS This study revealed significant risk factors for shoulder instability in the Chinese Han population. The humeral containing angle and the glenoid height-to-width ratio were risk factors for anterior shoulder instability.

Abstract
The shoulder relies heavily on coordinated muscle activity for normal function owing to its limited osseous constraint. However, previous studies have failed to examine the sophisticated interrelationship between all muscles. It is essential for these normal relationships to be defined as a basis for understanding pathology. Therefore, the primary aim of the study was to investigate shoulder inter-muscular coordination during different planes of shoulder elevation. Twenty healthy subjects were included. Electromyography was recorded from 14 shoulder girdle muscles as subjects performed shoulder flexion, scapula plane elevation, abduction and extension. Cross-correlation was used to examine the coordination between different muscles and muscle groups. Significantly higher coordination existed between the rotator cuff and deltoid muscle groups during the initial (Pearson Correlation Coefficient (PCC) = 0.79) and final (PCC = 0.74) stages of shoulder elevation compared to the mid-range (PCC = 0.34) (p = 0.020–0.035). Coordination between the deltoid and a functional adducting group comprising the latissimus dorsi and teres major was particularly high (PCC = 0.89) during early shoulder elevation. The destabilising force of the deltoid, during the initial stage of shoulder elevation, is balanced by the coordinated activity of the rotator cuff, latissimus dorsi and teres major. Stability requirements are lower during the mid-range of elevation. At the end-range of movement the demand for muscular stability again increases and higher coordination is seen between the deltoid and rotator cuff muscle groups. It is proposed that by appreciating the sophistication of normal shoulder function targeted evidence-based rehabilitation strategies for conditions such as subacromial impingement syndrome or shoulder instability can be developed.

METHODS This cross-sectional survey is part of a larger Sport Without Injury ProgrammE (SWIPE) project and provides baseline data before a cluster randomised controlled trial of an injury prevention program (Knee Control). A baseline survey (online and paper based) was collected from 47 teams with 471 youth floorball players from two provinces of Sweden before the start of the 2017 season. RESULTS The mean age for 140 females and 331 males was 13.7 (± 1.5) and 13.3 (± 1.0) years, respectively. The two most significant motivators for floorball participation were being part of the team (82% females, 75% males) and friends (65% females, 70% males). Fractures (84% females, 90% males), eye injuries (90% females, 83% males) and concussion (82% females, 83% males) were perceived as the most severe injuries. 93% of players believed that sports injuries can be prevented, while 74% believed it is unlikely that they will sustain an injury. Existing health problems at the beginning of the season were prevalent in 33% of players, with 65% being injuries and 35% illnesses. 17% of existing injuries at the start of the season caused time-loss from play and 17% required medical attention. CONCLUSION Social aspects were the greatest motivators for floorball participation in youths, suggesting that these factors are important to retain sports participants. The high number of health problems in youth is a concern; as such more effort, resources and priority should be given to sports safety programs. Many players believed that sports injuries can be prevented, possibly providing a fertile ground for implementation of such programs. LEVEL OF EVIDENCE IV.
