Abstract
The options for surgical treatment of an anterior labrum lesion have become extensive. Arthroscopic treatments are widely used as an improved minimally invasive option with a quick recovery. Arthroscopic treatment of the anterior glenoid labrum generally requires the creation of two working portals. However, arthroscopic treatment through a single anterior portal is still successful. Our single-portal technique avoids interference between instruments inserted through the two working portals and minimizes postoperative scarring, pain, and reduction in range of motion. The purpose of this article was to describe our single-portal arthroscopy technique to repair the anterior glenoid labrum.

Abstract
CLINICAL/METHODOLOGICAL PROBLEM The rotator cuff is a complex anatomical structure and the integrity is pivotal for the shoulder functionality. The pathologies are often multifactorial, resulting from degenerative, vascular, traumatic and mechanical factors. RADIOLOGICAL STANDARD PROCEDURES Radiography, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) form the pillars of radiological diagnostics. Each modality has specific advantages and limitations in the visualization and assessment of pathologies of the rotator cuff and biceps tendon. METHODOLOGICAL INNOVATIONS The MR arthrography offers additional insights in unclear cases by enhancing the differentiation between complete and partial tears. PERFORMANCE The MRI provides detailed information on tendon quality and associated damages, such as muscle atrophy and fat infiltration, making it the preferred method. The use of MR arthrography can identify defects through increased intra-articular pressure or contrast medium leakage. EVALUATION Muscle damage, as induced by edema in acute injuries or fatty degeneration in chronic conditions, can be evaluated using imaging techniques. Special attention is warranted for the infraspinatus, subscapularis and teres minor muscles due to their unique injury patterns and prevalences.

Abstract
PURPOSE The management of isolated SLAP lesions is still debated especially in athletes. Aims of the study were: 1. to analyse our algorithm to treat SLAP lesions starting from the selection of patients for surgery and 2. to correlate the familiarity for diabetes and hypothyroid disorders with post-operative results. METHODS Seventy-eight patients with isolated SLAP lesion were arthroscopically treated using knotless anchors and microfractures. All patients had a pre-operative and post-operative clinical examination according to Walch-Duplay, Constant, Rowe and Dash scores and interviewed for familiarity to diabetes and hypothyroid disorders. RESULTS About 68.8% of patients solved pain with rehabilitation. About 29% of patients returned to the sports activities. About 32% of patients were no responder to physiotherapy and were arthroscopically treated. About 53.9% of patients responded excellent, 34.7% good, 3.8% medium and 7.6% poor results according to Walch-Duplay score. The Constant score increased from 64 to 95, the Rowe score from 48 to 96. The outcomes were significantly worse in patients with familiarity for diabetes. CONCLUSIONS Microfractures and knotless anchor give long-term good results for the treatment of SLAP lesions in athletes. The familiarity for diabetes is an important risk factor that can lead to decreased outcomes.

Prevalence of the anterosuperior capsulolabral anatomical variations and their association with pathologies of the glenoid labrum: a systematic review and meta-analysis. Arch Orthop Trauma Surg 2023; 143:6295-6303. [PMID: 37351607 PMCID: PMC10491707 DOI: 10.1007/s00402-023-04932-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 05/23/2023] [Indexed: 06/24/2023]
Abstract
PURPOSE Differentiating the anatomical variations of the anterosuperior portion of the glenoid labrum from pathologies is important to avoid unnecessary iatrogenic complications resulting from inaccurate diagnosis. Additionally, the presence of several variations was reported to be conductive to lesions involving the glenoid labrum. Thus, the aim of this study was to state the prevalence rates of the sublabral recess, sublabral foramen, and the Buford complex, and to verify their association with labral lesions. METHODS Systematic search of electronic databases was conducted to gain potentially eligible literature. Suitable studies were selected in a two-round screening, and relevant data were subsequently extracted. Calculation of the pooled prevalence estimates, including sub-analyses on cohort size, study type, and geographical variance, was conducted. Pooled analysis of risk ratios (RR) was used to assess the conductive nature of the discussed variants to superior labrum anterior to posterior (SLAP) lesions. RESULTS The screening resulted in selection of 20 studies investigating the morphological features of the glenoid labrum, consisting of 7601 upper limbs. On the bases of random-effects meta-analysis the sublabral recess, sublabral foramen and Buford complex occur with a pooled prevalence of 57.2% (95% CI 30.0-84.4%), 13.5% (95% CI 8.2-18.9%), and 3.0% (95% CI 1.5-4.5), respectively. Moreover, individuals with Buford complex have RR 2.4 (95% CI 1.3-4.7) of developing SLAP lesions, especially type II (95.5%; 95% CI 86.1-100%), whereas such risk for sublabral recess and sublabral foramen was not statistically significant. CONCLUSION Morphological variants of the glenoid labrum posing diagnostic confusion are frequently observed. Gradually, the Buford complex may be a predisposing factor for sustaining a SLAP lesion.

Biceps Tenodesis Has Greater Expected Value Than Repair for Isolated Type II SLAP Tears: A Meta-analysis and Expected-Value Decision Analysis. Arthroscopy 2022; 38:2887-2896.e4. [PMID: 35662668 DOI: 10.1016/j.arthro.2022.05.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 05/04/2022] [Accepted: 05/13/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To use an expected-value decision analysis to determine the optimal treatment decision between repair and biceps tenodesis (BT) for an isolated type II SLAP injury. METHODS An expected-value decision analysis with sensitivity analysis was performed to systematically quantify the clinical decision. To determine outcome probabilities, a decision tree was constructed (repair vs BT) and a meta-analysis was conducted. To determine outcome utilities, we evaluated 70 patients with a chief complaint of shoulder pain regarding age, sex, Shoulder Activity Level, and visual analog scale score in terms of potential outcome preferences. Statistical fold-back analysis was performed to determine the optimal treatment. One-way sensitivity analysis determined the effect of changing the reinjury rate on the expected value of BT. RESULTS The overall expected value was 8.66 for BT versus 7.19 for SLAP repair. One-way sensitivity analysis showed that BT was the superior choice if reinjury rates were expected to be lower than 28%. Meta-analysis of 23 studies and 908 patients revealed that the probability of a "well" outcome was significantly greater for BT (87.8%; 95% confidence interval [CI], 74.9%-94.6%; I2 = 0.0%) than for SLAP repair (62.9%; 95% CI, 55.9%-69.3%; I2 = 65.9%; P = .0023). The rate of reinjury was 1.5% for BT (95% CI, 0.05%-33.8%; I2 = 0.0%) and 6.4% for repair (95% CI, 4.2%-9.6%; I2 = 24%), which was not statistically significantly different (P = .411). A total of 50 participants (mean age, 25.4 years [standard deviation, 8.9 years]; 76% male patients; 50% overhead athletes) met the inclusion criteria. Forty-six percent of participants had a high Shoulder Activity Level score. CONCLUSIONS Decision analysis showed that BT is preferred over repair for an isolated type II SLAP tear based on greater expected value of BT versus repair. Meta-analysis showed more frequent favorable outcomes with BT. Surgeons can use this information to tailor discussions with patients. LEVEL OF EVIDENCE Level IV, meta-analysis of Level I-IV studies.

Abstract
OBJECTIVE To summarize the relationship between shoulder instability and superior labrum anterior posterior (SLAP) lesion. METHODS The characteristics of shoulder instability and SLAP lesion were analyzed, and the relationship between them in pathogenesis, clinical symptoms, and biomechanics was discussed by referring to relevant domestic and foreign literature. RESULTS Shoulder instability and SLAP lesion can occur both spontaneously and respectively. SLAP lesion destroys the superior labrum integrity and the long head of biceps tendon (LHBT) insertion, causing excessive humeral head displacement against glenoid, and leading to shoulder instability. While chronic repetitive or acute high-energy traumatic shoulder instability can in turn aggravate SLAP lesion, resulting in expansion and increased degree of the original lesion. CONCLUSION SLAP lesion destroys mechanisms of shoulder stability, while shoulder instability causes tears of the upper labrum and the LHBT, showing a connection between shoulder instability and SLAP lesion. However, the existing evidence can only demonstrate that shoulder instability and SLAP lesion induce and promote the development of each other, instead of a necessary and sufficient condition. Therefore, the specific causal relationship between the two remains unknown and needs to be further studied.

Abstract
BACKGROUND Bankart lesions accompany superior labrum anteroposterior (SLAP) lesions; these are called SLAP type 5. PURPOSE To compare SLAP type 5 lesions using routine magnetic resonance arthrography (MRA) and thin-slice oblique sagittal proton density (PDW) sequences and correlation operation results. MATERIAL AND METHODS In total, 181 patients were admitted with shoulder instability. The study was completed with 44 patients. The presence or absence of isolated Bankart and SLAP type 5 lesions in routine MRA and PDW oblique sagittal images were evaluated separately. Absence of rupture scored 0 points, suspected ruptures scored 1 point, and apparent ruptures scored 2 points. The two scores were compared with the shoulder arthroscopy findings. RESULTS According to the findings in the shoulder arthroscopy, 40 patients had Bankart lesions and 17 patients had accompanying SLAP type 5 lesions. To detect a Bankart lesion, there was no significant difference between routine MRA sequences and PDW oblique sagittal images (P = 0.061). Routine MRA sensitivity was 95%, specificity 25%, positive predictive value (PPV) 92%, negative predictive value (NPV) 33%, while for PDW oblique sagittal images, sensitivity was 75%, specificity 100%, PPV 100%, and NPV 28.5%. In 8/17 type 5 SLAP lesions, routine MRA detected sensitivity 47%, specificity 92.6%, PPV 80%, and NPV 73.5%; in 14/17 SLAP type 5 lesions, PDW oblique sagittal images detected sensitivity 82%, specificity 100%, PPV 100%, and NPV 90% (P = 0.015). CONCLUSION The PDW oblique sagittal images may play a significant role in assessing the anterior and superior extent of the tears.

Abstract
INTRODUCTION AND IMPORTANCE The two major etiologies of shoulder superior labral tears anterior to posterior (SLAP) are traumatic and degenerative processes. Bucket handle tears of the superior labrum represent one-third of labral lesions. However, in this article, we present a double bucket handle tear which has been reported once in the literature. PRESENTATION OF CASE A 25-year-old male presented with complaint of chronic pain in his right shoulder with a remote history of traumatic dislocation. Physical examination revealed a positive apprehension test. Shoulder magnetic resonance imaging (MRI) showed a superior labral tear with a Hill-Sach lesion. Arthroscopy showed a double bucket handle tear of superior labrum and mild biceps tendonitis along with Bankart lesion. The tear was resected and the Bankart lesion was repaired followed by supervised physical therapy. Good clinical outcomes in form of resolution of pain and shoulder instability at six months were obtained. DISCUSSION SLAP tears are common shoulder lesion that is reported differently in the literature. Arthroscopic studies had reported the incidence between 3.9%-11.8. The diagnosis of such lesion relies on the clinical presentation and imaging. Knesek et al. classified SLAP lesions based on the integrity of the biceps anchor and the type of labral tear (Knesek et al., 2013). The standard treatment of symptomatic SLAP lesions is Arthroscopic debridement. However, non-operative management was described in the literature. CONCLUSION Double bucket handle injuries of the superior labrum are reported in literature once. These lesions can be treated with arthroscopic debridement and Bankart repair and followed by supervised physical therapy.

Abstract
Purpose To identify and characterize the top 50 most-cited articles regarding SLAP tears. Methods Referencing the methodology of previous citation analyses, varying Boolean searches were performed using the Web of Science database and the search terms yielding the greatest number of results was used. The top 50 most-cited articles were identified and the following data points were gathered from each article: author, institution, country of origin, year of publication, publishing journal, level of evidence, and citation density. Results The total number of citations was 7834, with a median of 106 citations. The top 50 list was largely composed of diagnostic level I, II, and III studies (5, 7, and 8 total publications, respectively) and therapeutic level III (6 publications) or level IV (10 publications). Most articles originated from the United States (40). In total, 19 of the top 50 most-cited articles were published in the American Journal of Sports Medicine, followed by Arthroscopy (15) and the Journal of Bone and Joint Surgery (5). Conclusions Our analysis demonstrated a correlation with earlier publications being cited more frequently than recent studies. Importantly, the current study found that therapeutic studies in the most cited list were largely level III or level IV evidence. This makes the management of SLAP tears seem anecdotal, with little in the way of high-impact level I or level II therapeutic studies. We must reconsider our current understanding of SLAP tears and their management with more studies that demonstrate a clearer treatment algorithm for these common injuries of the shoulder. Clinical Relevance Given the complexity of SLAP tears, this list of the most-cited articles can provide a reference point to better guide practice, resident education, and future areas of orthopaedic research.

Abstract
Purpose To identify and evaluate the top 50 most-cited articles pertaining to SLAP tears. Methods The ISI Web of Knowledge database was used to conduct a query for articles pertaining to SLAP tears. Our query was conducted in April 2020 with multiple Boolean operative combinations performed by 2 independent reviewers. Articles on the final list were further reviewed to extract the following data: manuscript title, first author, total citation count, year of publication, citation density since publication, current citation rate since 2013, journal, country of origin, and level of evidence. Results Our initial search yielded 2,597 articles. Within this cohort, the top 50 publications pertaining to SLAP tears were identified that met our search criteria. The top article was cited 802 times while the 50th ranked article was cited 46 times. The average number of citations per publication was 131, whereas the average citation density since year of publication was 7.3. No strong correlations were found between citation density and year published. Twelve journals published articles pertaining to SLAP tears, with Arthroscopy accounting for the greatest number (15 articles, 30%). Most articles were graded with a level of evidence (LOE) of IV (n = 24, 48%), followed by review articles without LOE (n = 8, 16%). Only 2 articles achieved an LOE of I (4%). Articles typically addressed the arthroscopic management (n = 11, 22%), whereas anatomy/classification (n =10, 20%), and outcomes (n = 9, 18%) also were reported. Conclusions This review provides a quantitative analysis of the most-referenced literature pertaining to SLAP tears. This body of knowledge helps surgeons search for literature regarding these injuries and identify trends regarding SLAP tear research. Clinical Relevance This research provides practitioners with an easily accessible and comprehensive collection of the major contributions regarding SLAP tears and offers insight into future areas for research.

Arthroscopic treatment of type II superior labral anterior to posterior (SLAP) lesions in a younger population: minimum 2-year outcomes are similar between SLAP repair and biceps tenodesis. Knee Surg Sports Traumatol Arthrosc 2021; 29:257-265. [PMID: 32253479 DOI: 10.1007/s00167-020-05971-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Accepted: 03/25/2020] [Indexed: 01/01/2023]
Abstract
PURPOSE Compared to a relatively older population over 30-40 years of age, the efficacy of biceps tenodesis for type II SLAP lesions in a younger population is not well studied. The purpose of this study was to compare outcomes between biceps tenodesis and labral repair for type II SLAP lesions in a young active population. METHODS Patients aged 15-40 who underwent primary arthroscopic biceps tenodesis or SLAP repair for type II SLAP tears between 2009 and 2016 were included. Shoulders with intraarticular chondral damage, full thickness rotator cuff tear, rotator cuff repair, labral repair outside of the superior labrum, bony subacromial decompression, and acromioclavicular joint resection were excluded. Patient-reported outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand Sports/Performing Arts Module (DASH-sport), visual analog scale (VAS) for pain, and satisfaction. Return to sport rates were also recorded. RESULTS Fifty-three patients (20 tenodesis, 33 repair) were available for minimum 2-year follow-up. Postoperatively, there were no significant differences in mean ASES, DASH-sport, VAS, and satisfaction between groups [ASES: tenodesis 86.3 vs. repair 86.4 (n.s.); DASH-sport: 11.0 vs. 22.5 (n.s.); VAS: 1.85 vs. 1.64 (n.s.); satisfaction: 8.50 vs. 8.00 (n.s.)]. Rate of return to pre-injury level of performance/competition in sport/physical activity was also similar between groups [tenodesis 63% vs. repair 50% (n.s.)]. CONCLUSIONS In a young active population, primary arthroscopic biceps tenodesis is a viable surgical alternative to labral repair for type II SLAP lesions. The results of this study suggest that indications for arthroscopic tenodesis can safely be expanded to a younger patient group than has previously been demonstrated in the literature.

Magnetic resonance-guided direct shoulder arthrography for the detection of superior labrum anterior-posterior lesions using an open 1.0-T MRI scanner. Pol J Radiol 2019; 84:e251-e257. [PMID: 31481997 PMCID: PMC6717947 DOI: 10.5114/pjr.2019.86894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Accepted: 04/23/2019] [Indexed: 11/26/2022] Open
Abstract
Purpose Direct magnetic resonance arthrography (MRA) offers increased diagnostic accuracy compared to conventional magnetic resonance imaging (MRI) in the detection of superior labrum anterior-posterior (SLAP) lesions. The aim of the present study was to present the technique of magnetic resonance-guided direct shoulder arthrography (MDSA), to evaluate the diagnostic value of this novel MRA procedure to detect SLAP lesions in comparison to the currently practiced MRI, and to correlate the radiological findings to the respective arthroscopic findings. Material and methods Fifty-six patients with clinical signs of a SLAP lesion underwent both MRI examination and MDSA prior to arthroscopic surgery. The MRI of both interventions were compared with the arthroscopic findings. Statistical analysis was performed using the McNemar test. Results Sensitivity, specificity, and accuracy for detecting SLAP lesions were 23%, 88%, and 54% on MRI and 80%, 81%, and 80% on MDSA, respectively. Sensitivity (p < 0.001) and accuracy (p = 0.001) in detection of SLAP lesions were significantly higher by MDSA whereas accuracy showed no significant differences (p = 0.625). Conclusions The MDSA can be performed in an open 1.0-T MRI scanner with a high level of technical success and a reasonable methodical effort. The modification of MRA provides the requirements as a practicable routine shoulder magnetic resonance examination including arthrography to detect SLAP lesions. The diagnostic value is significantly better than MRI examinations without included arthrography, which currently predominates the clinical practice to investigate shoulder pathology.

Abstract
BACKGROUND AND OBJECTIVE Superior labral anterior to posterior (SLAP) injuries are widely recognised as a cause of pain and dysfunction in the shoulders of active patients. The aims of the present study were to analyze SLAP injuries in the workplace, and to evaluate the reliability of physical examination and imaging techniques for the diagnosis of work-related SLAP injuries. MATERIAL AND METHODS Retrospective chart review of 58 SLAP injuries treated in our occupational health centre from 2005 to 2015 in 815 patients undergoing shoulder arthroscopy. Data were collected on mechanism of injury, clinical proceedings, complementary tests (contrasting the initial magnetic resonance imaging report with that of a radiologist specializing in musculoskeletal pathology), arthroscopy findings and treatments performed. RESULTS The most common mechanism of injury was acute injury while handling weight, in the majority of cases, above the head. SLAP injury was suspected in 41% of cases through anamnesis and physical exam, in 29% through the initial magnetic resonance imaging report, and in 52% through the specialised radiologist's report. In 78%, associated injuries were present, the most common being rotator cuff injuries. CONCLUSIONS SLAP injuries in the workplace are rare and are often a diagnostic finding during surgical intervention performed for a different associated injury. Arthro-magnetic resonance imaging and magnetic resonance imaging have lower reliability than physical exams in the diagnosis of work-related SLAP injuries. A radiologist specializing in musculoskeletal pathology could probably improve the reliability of imaging test interpretation in work-related SLAP injuries.

Abstract
Knowledge of the pertinent anatomy, pathogenesis, clinical presentation and treatment of the spectrum of injuries involving the superior glenoid labrum and biceps origin is required in treating the patient with a superior labrum anterior and posterior (SLAP) tear.Despite the plethora of literature regarding SLAP lesions, their clinical diagnosis remains challenging for a number of reasons.First, the diagnostic value of many of the available physical examination tests is inconsistent and ambiguous.Second, SLAP lesions most commonly occur concomitantly with other shoulder injuries.Third, SLAP lesions have no specific associated pain pattern.Outcomes following surgical treatment of SLAP tears vary depending on the method of treatment, associated pathology and patient characteristics.Biceps tenodesis has been receiving increasing attention as a possible treatment for SLAP tears.

Abstract
OBJECTIVE To present recommendations for the diagnosis, management, outcomes, and return to play of athletes with superior labral anterior-posterior (SLAP) injuries. BACKGROUND In overhead athletes, SLAP tears are common as either acute or chronic injuries. The clinical guidelines presented here were developed based on a systematic review of the current evidence and the consensus of the writing panel. Clinicians can use these guidelines to inform decision making regarding the diagnosis, acute and long-term conservative and surgical treatment, and expected outcomes of and return-to-play guidelines for athletes with SLAP injuries. RECOMMENDATIONS Physical examination tests may aid diagnosis; 6 tests are recommended for confirming and 1 test is recommended for ruling out a SLAP lesion. Combinations of tests may be helpful to diagnose SLAP lesions. Clinical trials directly comparing outcomes between surgical and nonoperative management are absent; however, in cohort trials, the reports of function and return-to-sport outcomes are similar for each management approach. Nonoperative management that includes rehabilitation, nonsteroidal anti-inflammatory drugs, and corticosteroid injections is recommended as the first line of treatment. Rehabilitation should address deficits in shoulder internal rotation, total arc of motion, and horizontal-adduction motion, as well as periscapular and glenohumeral muscle strength, endurance, and neuromuscular control. Most researchers have examined the outcomes of surgical management and found high levels of satisfaction and return of shoulder function, but the ability to return to sport varied widely, with 20% to 94% of patients returning to their sport after surgical or nonoperative management. On average, 55% of athletes returned to full participation in prior sports, but overhead athletes had a lower average return of 45%. Additional work is needed to define the criteria for diagnosing and guiding clinical decision making to optimize outcomes and return to play.

Abstract
Background To examine the outcomes of combined biceps tenodesis and indirect, intra-articular arthroscopic paralabral cyst decompression for the treatment of active duty military patients with superior labral from anterior to posterior tears and associated paralabral cysts. Methods Retrospective chart review of all active duty patients at our institution from 2011 to 2014 with superior labral from anterior to posterior tears and associated paralabral cysts at the spinoglenoid notch treated with biceps tenodesis and indirect arthroscopic cyst decompression. Patient charts were examined for pre- and post-operative parameters including strength, range of motion, visual analog scale pain score, American Shoulder and Elbow Surgeon Score, and Single Assessment Numeric Evaluation Score. Results Seven patients met study criteria. All patients presented with chronic shoulder pain and decreased external rotation strength, and three patients had clinically apparent muscular atrophy. Pre- and post-operative assessment showed external rotation strength increased from a median of 4 (range 4-4) to 5 (range 4-5; p-value = 0.014), Single Assessment Numeric Evaluation increased from a median of 50 (range 0-70) to 75 (range 30-95; p-value = 0.031), American Shoulder and Elbow Surgeon increased from a median of 46.0 (range 32.0-58.0) to 66.5 (range 58.0-98.0; p-value = 0.068), and visual analog scale pain score decreased from a median of 3 (range 1-8) to 0 (range 0-5; p-value = 0.017). Median follow-up was 66 wk (range 36-138 wk). The change was statistically significant (p <0.05) for external rotation strength, Single Assessment Numeric Evaluation, and VAS reduction. Post-operatively, all patients returned to full duty at a median of 20 wk (range 12-36 wk). Conclusion The use of biceps tenodesis in conjunction with indirect, intra-articular arthroscopic paralabral cyst decompression is an effective technique in an active patient population with superior labral from anterior to posterior tear with associated paralabral cyst.

Abstract
The unparalleled velocity achieved by overhead throwers subjects the shoulder to extreme forces, resulting in both adaptive changes and pathologic findings that can be detected at imaging. A key biomechanical principle of throwing is achieving maximum external rotation, which initially leads to adaptive changes that may result in a pathologic cascade of injuries. In addition to the well-established concepts of glenohumeral internal rotation deficit and internal impingement, osseous and soft-tissue injuries of the shoulder unique to overhead athletes are illustrated. The epidemiology and biomechanics of throwing injuries are reviewed, and examples from the authors' institutional experience with competitive, collegiate, and professional baseball players are provided to demonstrate the constellation of unique imaging findings seen in overhead throwing athletes. Given the widespread popularity of baseball, and other sports relying on overhead throwing motions at all playing levels from recreational to professional, it is important for radiologists in various practice settings to be familiar with the special mechanisms, locations, and types of shoulder injuries seen in the overhead throwing population. © RSNA, 2018.

Abstract
BACKGROUND The purpose of this study was to assess the frequency of superior labrum anterior posterior (SLAP) lesions, long head of biceps tendon (LHBT) pathologies, and superior rotator cuff tears accompanying subscapularis tears. We hypothesised that LHBT lesions, superior rotator cuff tears, and especially SLAP lesions were very frequent with subscapularis tears. METHODS The digital files of patients who underwent shoulder arthroscopy were reviewed retrospectively. One hundred and eleven patients with subscapularis tears evident on surgery videos were examined. Superior labrum, LHBT, and superior rotator cuff lesions were investigated by the authors of this study. The statistical analyses were made with SPSS statistics software, and significance was set at P < 0.05 value. RESULTS There were 111 patients with both subscapularis tears and surgery videos. The mean age was 58.09 ± 10.21, and 63.1% of the patients were female. 98.2% of the 111 patients had a SLAP lesion. 7.2% of those were SLAP I and 91% were SLAP II lesions while 1.8% were healthy. The 75.7% of the patients had a LHBT pathology, and 83.8% had superior cuff tear. CONCLUSIONS Subscapularis tears were almost always accompanied by SLAP lesions. On the other hand, biceps tendon pathologies and superior rotator cuff tears were also very frequent with subscapularis tears. LEVEL OF EVIDENCE Prognostic study, Level IV (retrospective cohort study).

Abstract
BACKGROUND/AIM For patients presenting with glenoid labral pathologies, there is little information on how operative interventions affect long-term outcomes and health-related quality of life (HRQoL). This study evaluated outcomes in operative and non-operative patients presenting with labral tears versus labral degenerations. METHODS Participants completed a pain Visual Analogue Scale (VAS), the Veterans RAND 12-item Health Survey, Western Ontario Rotator Cuff Index, American Shoulder and Elbow Surgeons instrument, Scapular Assistance Test (SAT), Shoulder Activity Level, and Single Assessment Numeric Evaluation at baseline and at 6-month, 12-month and 2-year follow-ups. χ2and Student's t-test were used to test the differences between categorical and continuous variables. Analysis of variance investigated the differences between groups, and linear regression analyses explored the relationship of baseline characteristics with outcome scores. RESULTS After 2 years, the operative cohort (n=68) significantly improved in all measures. The non-operative cohort (n=55) showed significant improvements in all scores except the mental component summary (MCS) and pain VAS. Labral tear patients (n=52) within the operative group (n=28) significantly improved in all measures except MCS. Non-operative labral tear patients (n=24) indicated significant improvements in all measures except MCS, VAS and SAT. Labral degeneration patients (n=71) within the operative group (n=27) significantly improved in all measures except MCS and SAT. Non-operative labral degeneration patients (n=44) indicated significant improvements in all measures except the physical component summary, MCS, VAS and SAT. CONCLUSION Patients who were surgically treated for labral tears or degenerations had significantly improved outcomes and HRQoL scores after 2 years compared with the non-operative cohort.

Abstract
Background/aim Health-related quality of life (HRQoL) is increasingly assessed within orthopaedic research. For those patients presenting with glenoid labral pathologies, there is little information on how baseline comorbidities affect long-term outcomes and HRQoL. This study aimed to investigate a model, including baseline comorbidities and demographics, to predict change in 2-year HRQoL scores in adult patients with glenoid labral tears or degenerations. Methods Participants provided Functional Comorbidity Index (FCI) scores and self-completed the Western Ontario Rotator Cuff (WORC) index at 6, 12 and 24 months. Univariable and multivariable linear regressions were performed to assess predictive quality of baseline comorbidities and demographics on the primary outcome measure of interest (change in WORC score). Results Multivariate regression with a continuous scaled FCI (β=617.8, p=0.042), age (by decade) (β=297, p<0.01), surgical group (β=−476.69, p<0.01) and an interaction term between FCI and age (β=−103.65, p=0.03) were significant predictors of change in WORC scores at 2-year follow-up (r2=0.293858). Multivariate regression with FCI scaled categorically reported only patients with three comorbidities (β=−454.06, p=0.057) and age (by decade) (β=156.87, p=0.04) as the only significant predictors of change in WORC scores at 2-year follow-up (r2=0.1279). Conclusion The continuous FCI model is better suited to predict future WORC and HRQoL scores among this patient population. Patients reporting with higher numbers of baseline comorbidities improved significantly more than patients with fewer comorbidities. This information on expected change in HRQoL scores among patients with a wide range of FCI scores at baseline may help guide treatment decisions based on these criteria.

Abstract
PURPOSE The physical examination of the shoulder is usually not reliable for the true diagnosis of superior glenoid labrum anterior to posterior (SLAP) lesions. Magnetic resonance imaging (MRI) has been routinely used for the diagnosis. This prospective study investigates the radiological diagnosis of the SLAP lesions and compares accuracy of arthroscopic and MRI classifications. METHODS One hundred thirty-two patients with positive physical examination signs using O'Brien, Yergason, resistance supination external rotation and Krank tests and MRI findings are included in the study. Shoulder MRIs were obtained for all patients within three months prior to the surgeries. SLAP lesion is detected in 90 and 102 patients according to MRI and arthroscopy, respectively. Arthroscopic and MRI classifications of the patients were performed according to modified Snyder classification. RESULTS Sensitivity and specificity of the MRI were found as 70.59 and 40%, respectively. No difference was detected between MRI and arthroscopy classifications in 52 (39%) patients. Although the diagnosis was compatible with arthroscopy in 34 (25%) patients, the classification was incompatible. In 46 (34%) of patients the diagnosis was incompatible with the MRI. CONCLUSION Although MRI is a good diagnostic tool for SLAP lesions, its use for the classification is limited. Level of evidence Level III, Diagnostic study.

Abstract
Repetitive, high-velocity overhead throwing can lead to several adaptive changes in the throwing shoulder, which over time lead to structural microtrauma and eventually overt injury. MR imaging is a useful imaging modality to evaluate these changes and to characterize their acuity and severity. Understanding the throwing motion and the effects of this motion on the structures of the shoulder can help radiologists to recognize these findings and provide useful information to referring physicians, which may affect the treatment of these athletes. This article reviews shoulder pathomechanics and MR imaging findings in overhead throwing athletes.

Abstract
Background/Purpose Superior labrum anterior and posterior (SLAP) lesion repair poses a significant discussion due to its high failure rate. The purpose of this study was to determine in which indications it is better to perform a tenodesis than a straight anatomical repair. The hypothesis was that in middle-aged patients and in those who did not suffer from a traumatic lesion, it is better to perform a long biceps tendon (LBT) tenodesis than a straight anatomical repair. Methods A total of 22 patients between the ages of 19 years and 55 years who underwent SLAP lesion repair between 2007 and 2011 were reviewed. The cases were divided into the following two groups: those with an isolated SLAP lesion (15 patients) and those with both a SLAP and a Bankart lesion (7 patients). This was a level IV longitudinal and retrospective study. Results Eight patients had persistent postoperative pain, which required to be revised from an anatomical repair to an LBT tenodesis. All of these patients were in the isolated SLAP lesion group. The average time between primary surgery and revision was 21.6 months. Patients over the age of 45 years had significantly poorer results after the repair. Conclusion Biceps tenodesis is a feasible therapeutic alternative to anatomical repair for the treatment of SLAP lesions in middle-aged patients; the reinsertion failure rates for this type of lesion are rather discouraging due to the high percentage of revision surgeries that must be carried out after the primary intervention.

Abstract
BACKGROUND Arthroscopic repair of type II superior labrum from anterior to posterior (SLAP) lesions is a common surgical procedure. However, anatomic healing following repair has rarely been investigated. The intraobserver and interobserver reliability of magnetic resonance imaging arthrography (MRA) following type II SLAP repair has not previously been investigated. This is of particular interest due to recent reports of poor clinical results following type II SLAP lesion repair. PURPOSE To evaluate the MRA findings following arthroscopic type II SLAP lesion repair and determine its intraobserver and interobserver reliability. STUDY DESIGN Cohort study (diagnosis), Level of Evidence, 2. METHODS Twenty-five patients with an isolated type II SLAP lesion (confirmed via diagnostic arthroscopy) underwent standard suture anchor-based repair. At a mean of 25.2 months post-operatively, patients underwent a standardized MRA protocol to investigate the integrity of the repair. MRAs were independently reviewed by two radiologists and a fellowship trained shoulder surgeon. The outcomes were classified as healed SLAP repair or re-torn SLAP repair. RESULTS On average, 54% of MRAs were interpreted as healed SLAP repairs while 46% of MRAs were interpreted as having a re-torn SLAP repair. Overall, only 43% of the studies had 100% agreement across all interpretations. The intraobserver reliability ranged from 0.71 to 0.81 while the interobserver reliability between readers ranged from 0.13 to 0.44 (Table 1). CONCLUSION The intraobserver agreement of MRA in the evaluation of type II SLAP repair was substantial to excellent. However, the interobserver agreement of MRA was poor to fair. As a result, the routine use of MRA in the evaluation of type II SLAP lesion repair should be utilized with caution. A global evaluation of the patient, including detailed history and physical examination, is paramount in determining the cause of failure and one should not rely on MRA alone.

Abstract
PURPOSE To evaluate the presence of a superior labral cleft at postoperative computed tomographic (CT) arthrography after superior labral anterior-to-posterior lesion (SLAP) repair and to correlate CT arthrographic appearance with clinical outcomes. MATERIALS AND METHODS The institutional review board approved this retrospective study, and the requirement to obtain informed consent was waived. Fifty-six patients who underwent CT arthrography after arthroscopic SLAP repair were included. Two musculoskeletal radiologists retrospectively reviewed CT arthrographic images for the presence, size, location, direction, and shape of a superior labral cleft, which was defined as a detectable contrast material-filled focal discontinuity of the labrum within anchor fixation sites of the glenoid. In addition, the glenoid osteolysis ratio was calculated on the basis of the CT arthrographic images. Clinical outcome was evaluated with use of the American Shoulder and Elbow Surgeons (ASES) scoring system. Continuous variables, such as patient age, interval between imaging and surgery, ASES score, and osteolysis ratio, were compared by using the Mann-Whitney U test. RESULTS A superior labral cleft was observed in 27 of the 56 patients (48%). The mean width and depth of the superior labral clefts was 2.1 mm ± 1.1 and 2.8 mm ± 0.8, respectively. The superior labral clefts extended posterior to the biceps anchor in 16 of the 27 patients (59%), were curved medially in 24 (89%), and had a smooth margin in 22 (81%). No significant association was observed between the presence of a superior labral cleft and the ASES score (P = .805) or patient age (P = .290). Superior labral clefts were observed more commonly in cases with a long interval since surgery (P = .007) and a high osteolysis ratio (P = .011). CONCLUSION Superior labral clefts are frequently observed on CT arthrographic images after arthroscopic SLAP repair and do not correlate with clinical outcome.

Abstract
PURPOSE Shoulder pathology, particularly SLAP (superior labrum anterior-posterior) lesions, is prevalent in overhead athletes and physically active individuals. The aim of this study is to quantify the burden of SLAP lesions in the military and establish risk factors for diagnosis. METHODS A retrospective analysis of all service members diagnosed with a SLAP lesion (International Classification of Disease, Ninth Revision code 840.70) in the Defense Medical Epidemiological Database between 2002 and 2009 was performed. Available epidemiological risk factors including age, sex, race, military rank, and branch of service were evaluated using multivariate Poisson regression analysis, and cumulative and subgroup incidence rates were calculated. RESULTS During the study period, approximately 23,632 SLAP lesions were diagnosed among a population at risk of 11,082,738, resulting in an adjusted incidence rate of 2.13 per 1,000 person-years. The adjusted annual incidence rate for SLAP lesions increased from 0.31 cases per 1,000 person-years in 2002 to 1.88 cases per 1,000 person-years in 2009, with an average annual increase of 21.2 % (95 % CI 20.7 %, 22.0 %, p < 0.0001) during the study period. Age, sex, race, branch of military service, and military rank were independent risk factors associated with the incidence rate of SLAP lesion (p < 0.01). Male service members were over twofold more likely (IRR, 2.12; 95 % CI 2.01, 2.23) to sustain a SLAP lesion when compared with females. Increasing age category was associated with a statistically significant increase in the incidence rate for SLAP lesions in the present study (p < 0.001). After controlling for the other variables, those individuals of white race, enlisted ranks, or Marine Corps service experienced the highest incidence rates for SLAP. CONCLUSION This is the first study to establish the epidemiology of SLAP lesions within an active military cohort in the American population. Sex, age, race, military rank, and branch of military service were all independently associated with the incidence rate of SLAP lesions in this physically active population at high risk for shoulder injury.

Abstract
PURPOSE To use the clinical prediction rule process to identify patient variables, measured on initial clinical presentation, that would be predictive of failure to achieve satisfactory improvement, while following a rehabilitation program, in the modification of SLAP injury symptoms and dysfunction. METHODS A cohort of patients received the clinical diagnosis of a SLAP lesion based on specific history and examination findings and/or magnetic resonance imaging. They underwent a physical examination of the kinetic chain and shoulder, including tests for labral injury. Patients followed a standardized physical therapy program emphasizing restoration of demonstrated strength, flexibility, and strength-balance deficits. At 6 weeks' follow-up, patients were re-evaluated and divided into those recommended for surgery (RS) and those not recommended for surgery (NRS). Bivariate logistic regression was performed to identify the best combination of predictive factors. RESULTS Fifty-eight patients (aged 39 ± 11 years, 45 men) were included. Of these, 31 (53%) were categorized as NRS and 27 (47%) as RS. The presence of a painful arc of motion (odds ratio, 3.95; P = .024) and the presence of increased forward scapular posture (odds ratio, 1.27; P = .094) on the injured side were predictive of being in the RS group. This finding indicates that the odds of being in the RS group increased 4 times when a positive painful arc was present and increased 27% with every 1-cm increase in involved anterior shoulder posture. CONCLUSIONS A structured rehabilitation program resulted in modification of symptoms and improved function at 6 weeks' follow-up in over half of patients in the study group. On initial evaluation, the presence of a painful arc of overhead motion, indicating loss of normal glenohumeral kinematics, and the presence of forward shoulder posture, indicating an altered scapular position, represent negative predictive factors for success of rehabilitation. Future validation of the model in a larger population is necessary. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
BACKGROUND Impingement is a common cause of shoulder pain. Impingement mechanisms may occur subacromially (under the coraco-acromial arch) or internally (within the shoulder joint), and a number of secondary pathologies may be associated. These include subacromial-subdeltoid bursitis (inflammation of the subacromial portion of the bursa, the subdeltoid portion, or both), tendinopathy or tears affecting the rotator cuff or the long head of biceps tendon, and glenoid labral damage. Accurate diagnosis based on physical tests would facilitate early optimisation of the clinical management approach. Most people with shoulder pain are diagnosed and managed in the primary care setting. OBJECTIVES To evaluate the diagnostic accuracy of physical tests for shoulder impingements (subacromial or internal) or local lesions of bursa, rotator cuff or labrum that may accompany impingement, in people whose symptoms and/or history suggest any of these disorders. SEARCH METHODS We searched electronic databases for primary studies in two stages. In the first stage, we searched MEDLINE, EMBASE, CINAHL, AMED and DARE (all from inception to November 2005). In the second stage, we searched MEDLINE, EMBASE and AMED (2005 to 15 February 2010). Searches were delimited to articles written in English. SELECTION CRITERIA We considered for inclusion diagnostic test accuracy studies that directly compared the accuracy of one or more physical index tests for shoulder impingement against a reference test in any clinical setting. We considered diagnostic test accuracy studies with cross-sectional or cohort designs (retrospective or prospective), case-control studies and randomised controlled trials. DATA COLLECTION AND ANALYSIS Two pairs of review authors independently performed study selection, assessed the study quality using QUADAS, and extracted data onto a purpose-designed form, noting patient characteristics (including care setting), study design, index tests and reference standard, and the diagnostic 2 x 2 table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for the index tests. Meta-analysis was not performed. MAIN RESULTS We included 33 studies involving 4002 shoulders in 3852 patients. Although 28 studies were prospective, study quality was still generally poor. Mainly reflecting the use of surgery as a reference test in most studies, all but two studies were judged as not meeting the criteria for having a representative spectrum of patients. However, even these two studies only partly recruited from primary care.The target conditions assessed in the 33 studies were grouped under five main categories: subacromial or internal impingement, rotator cuff tendinopathy or tears, long head of biceps tendinopathy or tears, glenoid labral lesions and multiple undifferentiated target conditions. The majority of studies used arthroscopic surgery as the reference standard. Eight studies utilised reference standards which were potentially applicable to primary care (local anaesthesia, one study; ultrasound, three studies) or the hospital outpatient setting (magnetic resonance imaging, four studies). One study used a variety of reference standards, some applicable to primary care or the hospital outpatient setting. In two of these studies the reference standard used was acceptable for identifying the target condition, but in six it was only partially so. The studies evaluated numerous standard, modified, or combination index tests and 14 novel index tests. There were 170 target condition/index test combinations, but only six instances of any index test being performed and interpreted similarly in two studies. Only two studies of a modified empty can test for full thickness tear of the rotator cuff, and two studies of a modified anterior slide test for type II superior labrum anterior to posterior (SLAP) lesions, were clinically homogenous. Due to the limited number of studies, meta-analyses were considered inappropriate. Sensitivity and specificity estimates from each study are presented on forest plots for the 170 target condition/index test combinations grouped according to target condition. AUTHORS' CONCLUSIONS There is insufficient evidence upon which to base selection of physical tests for shoulder impingements, and local lesions of bursa, tendon or labrum that may accompany impingement, in primary care. The large body of literature revealed extreme diversity in the performance and interpretation of tests, which hinders synthesis of the evidence and/or clinical applicability.

Abstract
Background. The purpose of this study was to report on any prognostic factors that had a significant effect on clinical outcomes following arthroscopic Type II SLAP repairs. Methods. Consecutive patients who underwent arthroscopic Type II SLAP repair were retrospectively identified and invited to return for follow-up examination and questionnaire. Statistical analysis was performed to determine associations between potential prognostic factors and failure of SLAP repair as defined by ASES of less than 50 and/or revision surgery. Results. Sixty-two patients with an average age of 36 ± 13 years met the study criteria with a mean followup of 3.3 years. There were statistically significant improvements in mean ASES score, forward elevation, and external rotation among patients. Significant associations were identified between ASES score less than 50 and age greater than 40 years; alcohol/tobacco use; coexisting diabetes; pain in the bicipital groove on examination; positive O'Brien's, Speed's, and/or Yergason's tests; and high levels of lifting required at work. There was a significant improvement in ASES at final followup. Conclusions. Patients younger than 20 and overhead throwers had significant associations with cases requiring revision surgery. The results from this study may be used to assist in patient selection for SLAP surgery.

Abstract
Injury to the superior glenoid labrum is increasingly recognized as a significant source of shoulder pain and dysfunction in the throwing athlete. Several theories have been proposed to explain the pathogenesis of superior labral anterior posterior (SLAP) tears. The clinical examination of the superior labrum-biceps tendon complex remains challenging because of a high association of other shoulder injuries in overhead athletes. Many physical examination findings have high sensitivity and low specificity. Advances in soft tissue imaging such as magnetic resonance arthrography allow for improved detection of labrum and biceps tendon lesions, although correlation with history and physical examination is critical to identify symptomatic lesions. Proper treatment of throwers with SLAP tears requires a thorough understanding of the altered biomechanics and the indications for nonoperative management and arthroscopic treatment of these lesions.

Abstract
PURPOSE The aim of this study was to evaluate the clinical and structural outcome of the new fixation technique of type-II SLAP repair using double anchors compared with conventional method. METHODS Twenty-eight patients with 29 shoulders, who were followed up for at least 1 year after surgery, were enrolled. Fourteen shoulders were treated using the new technique (group 1), and 15 shoulders using the conventional technique (group 2). The clinical outcomes were evaluated using two different functional scores, the pain VAS and range of motion. The postoperative labral integrity was determined by magnetic resonance imaging at 1 year after surgery. RESULTS At postoperative 6 months, all functional scores of group 1 were superior to group 2, particularly in pain VAS and Constant Scoring System. All ranges of motion in group 1 showed a better result than in group 2, particularly in forward flexion and external rotation at 90° abduction (88° ± 4.8 in group 1 and 84° ± 9.2 in group 2, P = 0.03). At postoperative 12 months and the last visit, all functional scores in group 1 were superior to those in group 2 and all external rotations at 90° of abduction in group 1 showed significantly better results than those of group 2. All patients in group 1 showed complete healing of the repaired SLAP lesion but one patient in group 2 showed partial detachments on the MRI. CONCLUSIONS This new technique provides anatomical restoration of a SLAP lesion and yields successful clinical and structural outcomes at a short-term follow-up.

Abstract
BACKGROUND Treatment of superior labral anterior posterior (SLAP) tears remains controversial, particularly in older age groups. Repair, debridement, biceps tenodesis, tenotomy, and observation have been recommended depending on patient characteristics, but there have not been any large epidemiologic studies investigating treatment trends. PURPOSE To investigate current trends in SLAP repair across time, gender, age, and regions in the United States. STUDY DESIGN Descriptive epidemiology study. METHODS Patients who underwent arthroscopic SLAP repair (Current Procedural Terminology [CPT] code 29807) were identified using a publicly available national database of insurance records (PearlDiver Patient Records Database) during years 2004 through 2009. Factors identified for each patient included gender, age group, and region in the United States. Logistic regression analysis and the chi-square test were used for statistical measures. RESULTS From 2004 to 2009 there were 25,574 cases of arthroscopic SLAP repair identified, of which 75% were male patients and 25% were female patients. There was a significant rise in cases of SLAP repair from 2004 to 2009 as the incidence of SLAP repair increased from 17.0 for every 10,000 patients with an orthopaedic International Classification of Diseases, Ninth Revision (ICD-9) or CPT code in 2004 to 28.1 in 2009 (P < .0001). Age analysis revealed the highest incidence in the 20-29-year (29.1 per 10,000) and 40-49-year (27.8 per 10,000) age groups. Men (37.3 per 10,000) had a significantly higher incidence of repairs than did women (10.7 per 10,000). The West (24.6 per 10,000) and South (24.4 per 10,000) regions also demonstrated a higher incidence than the Midwest (20.5 per 10,000) and Northeast (20.1 per 10,000) regions (P < .0001). CONCLUSION Our analysis illustrates that surgeons are performing significantly more arthroscopic SLAP repairs each year. The highest incidence of repair is in the 20-29- and 40-49-year age groups, and a significant gender difference exists, with men having a threefold higher incidence of repair.

Abstract
PURPOSE To compare the diagnostic performance of computed tomographic (CT) arthrography performed with external rotation and active supination (ERAS) with that of CT angiography performed in the neutral position for superior labral anterior-to-posterior (SLAP) lesions. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. CT arthrography in neutral and ERAS positions was performed in 49 shoulders of 47 patients, with subsequent arthroscopic confirmation of the status of the superior labrum. Two musculoskeletal radiologists (1 and 8 years of experience) reviewed images and expressed the likelihood of SLAP lesions by using a continuous scale; they also measured gap widths and depths of labral detachment. Overall performances for the detection of SLAP lesions were determined with receiver-operating characteristic (ROC) analysis. Gap widths and depths measured with the two types of CT arthrography were also compared. RESULTS For reader 1, area under the ROC curve increased insignificantly from 0.932 in the neutral position to 0.974 in the ERAS position (P = .210), whereas for reader 2, it increased significantly from 0.914 to 0.984 (P = .032). Mean gap width of SLAP lesion was significantly greater according to ERAS CT arthrography (3.98 mm ± 2.48 [standard deviation] vs 1.61 mm ± 1.11), whereas mean gap depth was not significantly different. Gap width and depth cutoff values for the detection of a SLAP lesion with ERAS CT arthrography were 1.7 mm and 1.6 mm, respectively. CONCLUSION ERAS CT arthrography might improve the detection of SLAP lesions compared with neutral-position CT arthrography.

Abstract
PURPOSE This study investigates factors associated with failure and reoperation after glenoid labrum repair. METHODS We studied a nonconcurrent cohort of consecutive patients undergoing arthroscopic superior labrum repair at a single institution by 2 fellowship-trained surgeons over a 10-year period. RESULTS There were 348 patients included in this study with a mean age of 33.4 years (95% confidence interval [CI], 32.1 to 35.9) and a mean clinical follow-up of 12.3 months (95% CI, 10.9 to 13.8). The overall reoperation rate was 6.3%, with a revision labrum repair rate of 4.3%. Subsequent surgery and failure after arthroscopic labrum repair were significantly correlated with Workers' Compensation claims (odds ratio [OR], 4.6; P < .001; 95% CI, 1.8 to 11.7), the use of tobacco (OR, 12.0; P = .03; 95% CI, 1.2 to 114.9), and the use of absorbable poly-L/D-lactic acid (PLDLA) anchors (100% correlation, P < .001). The OR for having repeat surgery was 12.7 (95% CI, 4.9 to 32.9; P < .001) with poly-96L/4D-lactic acid (Mini-Revo; Linvatec, Largo, FL) and also increased with the use of poly-70L/30D-lactic acid (Bio-Fastak and Bio-Suturetak; Arthrex, Naples, FL) anchor material (P = .04) after removal of the patients exposed to poly-96L/4D-lactic acid anchors. The rates of repeat surgery with PLDLA anchors from Linvatec and PLDLA anchors from Arthrex were 24% and 4%, respectively. None of the patients treated with nonabsorbable suture anchors (polyether ether ketone or metallic) returned to the operating room (P < .001). After we controlled for associated factors in a multivariate analysis, the use of absorbable anchors, in particular poly-96L/4D-lactic acid anchors (OR, 14.7; P < .001), and having a work-related injury (OR, 8.1; P < .001) remained independent factors associated with both repeat surgery and revision superior labrum repair. CONCLUSIONS Bioabsorbable PLDLA anchor material led to significantly more SLAP repair failures and reoperations compared with nonabsorbable suture anchors. Our recommendation is that glenoid labrum repairs be performed with nondegradable material and, specifically, that the use of anchors composed of PLDLA material should be avoided.

Abstract
PURPOSE The purpose of this study was to evaluate the prevalence of SLAP and biceps reflection pulley lesions. The hypothesis was that these lesions do not occur concomitantly and they have a different etiology. METHODS We prospectively analyzed 3,395 shoulder arthroscopies that were independently performed by 2 surgeons between 2004 and 2008 regarding the prevalence of SLAP and biceps pulley lesions. Intraoperative findings were correlated with patient history and clinical examination. Exclusion criteria were type I SLAP lesions, full-thickness rotator cuff tears, and a history of shoulder dislocation. RESULTS This study included 182 patients with SLAP lesions (prevalence, 5.4%; 138 men; mean age, 47 years) and 87 patients with pulley lesions (prevalence, 2.6%; 63 men; mean age, 49 years). Isolated SLAP lesions were present in 157 cases, and isolated pulley lesions in 62 cases. The concomitant presence of a SLAP lesion and pulley lesion was significantly rare (10%, P = .003). In 55 (35%; 42 men [76%]; mean age, 43 years) of the cases with isolated SLAP lesions and 40 (65%; 27 men [68%]; mean age, 49 years) with isolated pulley lesions, there was a significant association with history of trauma (P < .01). Most SLAP lesions (32 [58%], P = .174 [not significant]) and most pulley lesions (28 [70%], P < .01) resulted from falling on the outstretched arm with external arm rotation in SLAP lesions and internal rotation in pulley lesions (P > .05). CONCLUSIONS The concomitant presence of biceps tendon-associated lesions in the form of SLAP and pulley lesions is significantly rare. A history of falling on the abducted and externally rotated arm was typical in patients with SLAP lesions, whereas a fall on the arm with internal rotation was often noted in patients with pulley lesions.

Abstract
Due to the complexity of shoulder pathomechanics in the overhead athlete, injuries located in the superior aspect of the glenoid, known as superior labral anterior to posterior (SLAP) lesions, are often a surgical and rehabilitation challenge. In an effort to determine surgical versus conservative care of SLAP lesions a thorough clinical examination and evaluation are necessary. If surgery is identified as the treatment of choice, post operative rehabilitation will vary pending surgical findings including the extent and location of the SLAP lesion, and other concomitant findings and procedures. This manuscript will provide an overview of the pathology, examination and evaluation of SLAP lesions, surgical management and post operative rehabilitation following various SLAP categories.

Abstract
From 2004 to 2008 we evaluated 431 SLAP lesions during 3,395 shoulder arthroscopies and compared two groups of patients, one with SLAP lesion as group I and one without SLAP lesions as group II. Exclusion of type I SLAP lesions, rotator cuff tears and history of dislocation of the shoulder in both groups left 182 cases in group I, and additionally, exclusion of all-type SLAP lesions left 251 patients in group II. In group I, SLAP lesion-associated chondral lesions were present in 20% at the humerus (4% group II, p = 0.005), 18% at the glenoid (5% in group II, p = 0.05) and 14% glenohumeral (3% group II, p = 0.04). We observed a pattern of typical localization of SLAP-associated chondral lesions at the humerus underneath the biceps tendon (78%) and at the anterior half of the glenoid (63%) in group I in contrast to the central region of the humerus (82%) and the central region at the glenoid (55%) in group II. The association of SLAP and chondral lesions was not influenced by the presence of trauma or age of the patients. SLAP lesions seem to be a risk factor for subsequent early onset of osteoarthritis either caused by a bicipital chondral print or glenohumeral instability or a combination of both.

Abstract
HYPOTHESIS This study evaluated the diagnostic efficacy of computed tomography arthrography (CTA) in the assessment of various shoulder pathologies with arthroscopic correlation. We hypothesized that CTA would be cost-effective and effectively comparable with magnetic resonance arthrography (MRA) for assessing labral detachments and full-thickness rotator cuff tears. MATERIALS AND METHODS A musculoskeletal radiologist interpreted CTAs for 78 patients and MRAs for 70 patients. Each imaging study was evaluated for the presence of bony (Hill-Sachs) or labral (Bankart or superior labrum anteroposterior [SLAP]) lesions, and rotator cuff disorder (full- or partial-thickness tears). All patients subsequently underwent arthroscopic surgery. Detailed arthroscopic findings were reported and compared with CTA and MRA findings. The sensitivity, specificity, kappa coefficients, and the area under the receiver operating characteristic (AUROC) curve were calculated. RESULTS The sensitivity, specificity, and agreement were comparable in each imaging study for Bankart, SLAP, and Hill-Sachs lesions, and full-thickness rotator cuff tears, but those of CTA were significantly lower than MRA for partial-thickness cuff tears. The AUROC curve for CTA and MRA were not significantly different for any of the pathologies, except partial-thickness cuff tears. CONCLUSIONS Our data suggest that CTA is a cost-effective, useful method in the preoperative evaluation of labral abnormalities, such as Bankart and SLAP lesions. It may also be useful for the detection of full-thickness rotator cuff tears. LEVEL OF EVIDENCE Level I; Diagnostic study.

Abstract
PURPOSE The purpose of this report is to present a new provocative maneuver, the passive distraction test (PDT), as an examination tool to be used in the evaluation of patients thought to have a SLAP lesion and to compare its accuracy, precision, and reproducibility alone and in conjunction with previously published maneuvers. METHODS A retrospective analysis of 319 consecutive arthroscopies performed between May 2001 and November 2003 was performed. A total of 65 cases were excluded, 53 because of limitation of elevation to less than 150 degrees or pain in the starting test position and 12 who had previous shoulder procedures performed by the senior author, leaving 254 cases for review. A thorough history was obtained and a thorough physical examination performed with a focus on the involved shoulder including specific provocative maneuvers for the clinical diagnosis of a SLAP lesion. The active compression test, the anterior slide test, and the PDT were used to clinically diagnose a SLAP lesion. The results from the 3 provocative maneuvers were compared with the arthroscopic findings to determine the sensitivity, specificity, negative predictive value (NPV), and positive predictive value of each test alone and in a logical combination. RESULTS Of 254 shoulder arthroscopies, 61 had a clinically significant SLAP lesion, for an incidence of 24%. The sensitivity and specificity for the PDT were 53% and 94%, respectively, with an NPV of 87% and positive predictive value of 72%. In combination, the PDT and the active compression test yielded an NPV of 90.5%. CONCLUSIONS The PDT can be used alone or in combination to aid in the clinical evaluation and diagnosis of a SLAP lesion. LEVEL OF EVIDENCE Level IV, retrospective, diagnostic, sensitivity-specificity study.

Abstract
In the evaluation of the painful shoulder, especially in the overhead athlete, diagnosing superior labrum anterior and posterior (SLAP) lesions continues to challenge the clinician because of 1) the lack of specificity of examination tests for SLAP; 2) a paucity of well-controlled studies of those tests; and 3) the presence of coexisting confounding abnormalities. Some evidence indicates that multiple positive tests increase the likelihood that a SLAP lesion is present, but no one physical examination finding conclusively makes that diagnosis. The goals of this article were to review the physical examination techniques for making the diagnosis of SLAP lesions, to evaluate the clinical usefulness of those examinations, and to review the role of magnetic resonance imaging in making the diagnosis.

Abstract
PURPOSE The purpose of this study was to evaluate glenohumeral motion after knotless anchor repair of type II SLAP lesions versus repair with simple suture arthroscopic knot-tying techniques and to compare the initial fixation strength of the 2 repair techniques. METHODS Six matched-pair cadaveric shoulders were tested in an uninjured condition, after creation of a type II SLAP tear, and after repair with either a knotless repair with two 3.5-mm Bio-PushLock anchors (Arthrex, Naples, FL) or a simple suture repair with two 3.0-mm Bio-SutureTak anchors (Arthrex) placed anterior and posterior to the biceps tendon. Glenohumeral rotation, translation, and kinematics were measured. The SLAP repairs were then loaded to failure perpendicular to the glenoid face. RESULTS Glenohumeral rotation increased after creation of a type II SLAP lesion and was restored to the intact state after both repairs. There was no significant difference in glenohumeral translation or kinematics with SLAP lesion or either repair technique. There was no significant difference between stiffness, yield load, or ultimate load of the 2 repairs. Simple suture repairs failed most commonly by knot breakage, and knotless repairs failed by suture slippage around the anchor. CONCLUSIONS Knotless anchor repairs of type II SLAP lesions restore glenohumeral rotation as well as simple suture arthroscopic repair techniques without overconstraining the shoulder. In addition, the initial fixation strength of knotless anchor repairs of type II SLAP lesions is similar to that of simple suture repairs. CLINICAL RELEVANCE Knotless anchor repairs of type II SLAP lesions restore capsulolabral anatomy without overconstraining the shoulder.
