Surgical Treatment of Shoulder Pathologies in Professional Gymnasts: Findings, Treatment, and Clinical Outcomes.

Background: This study aims to investigate the impact of shoulder surgery on professional gymnasts through a case series, analyzing the mechanisms of injury and the shoulder lesion patterns, and reporting the clinical outcomes and return to sport. Methods: Twenty-nine surgically treated shoulders in twenty-seven professional gymnasts were retrospectively analyzed. Patients were stratified based on predominant symptoms and anatomical lesions in painful or unstable shoulders. Demographic and injury data, pathological findings, surgical procedure information, and data on time and level of return to sport were collected. Results: The average age of participants was 20.2 ± 3.8 years. Acute traumatic onset was reported in 51.8% of cases. Shoulders were categorized as painful in 13 cases and unstable in 16 cases. The most common pathologies were capsulolabral injuries (72%), biceps injuries (48%), and rotator cuff injuries (40%). All of the athletes returned to training within an average of 7.3 months, while the return to competition rate was 56%, achieved in an average of 10.3 months. The sport-specific subjective shoulder value was 84.8% ± 16.6%. Half of the patients who stopped competition reported reasons related to symptom persistence, while the other half reported personal reasons. No significant difference in the return to sport was reported in the cases of painful or unstable shoulder. Conclusions: Professional gymnasts requiring shoulder surgery commonly present multiple and complex lesions. Returning to training was possible in all cases; however, the possibility of persisting symptoms and other personal factors which may compromise the return to competition should be discussed with the athlete to give them insights into the possible outcomes.

The Association between SLAP Lesions and Critical Shoulder Angle and Glenoid Depth.

PURPOSE OF THE STUDY: The critical shoulder angle (CSA) is formed by the combination of glenoid inclination and acromial index and has been shown related to rotator cuff tears and glenohumeral osteoarthritis. SLAP lesions today have an important place among bicipitolabral pathologies that cause intensive shoulder pain. We aimed to investigate the relationship between CSA and glenoid depth and SLAP lesions. MATERIAL AND METHODS: Between March 2017 and January 2022, 279 consecutive shoulder arthroscopy patients' MRI images were retrospectively examined. After the exclusion criteria, 191 patients were eligible. Patients with SLAP lesions (n=37) were assembled as the study group (Group 1), and patients with intact superior labrum (n=154) were named as the control group (Group 2). Critical shoulder angle (CSA) and glenoid depth measurements were performed using the preoperative MRI images. RESULTS: A total of 191 patients, of whom 84 were male (44%) were included. The mean age was 49.9±14.96 (range 18-79). There was a statistically signifi cant difference between the SLAP group (Group 1) and the control group (Group 2) in terms of CSA (p=0.032). The mean CSA was 31.66°±3.51° in Group 1 and 33.57° ±5.01° in Group 2. The cut-off value for CSA in patients with SLAP lesions was calculated as 32.85° and the area under the curve was 0.61, therefore a satisfactory association was observed between the groups. The mean glenoid depth was 4.32 ±1.25 mm in Group 1, and 4.39 ±0.32 mm in Group 2. There was no statistically signifi cant difference between the groups in terms of glenoid depth (p=0.136) and also no association between the glenoid depth and SLAP lesions was observed (cut-off=4.45 mm, AUC=0.32). CONCLUSIONS: Low CSA is associated with SLAP lesions, just as in glenohumeral osteoarthritis. Further prospective clinical studies are needed to enlighten the predisposing effect of CSA to SLAP lesions and the success of superior labral repairs. LEVEL OF EVIDENCE: Retrospective comparative study, Level III.

Spontaneous resolution of spinoglenoid ganglion cyst: a case series.

BACKGROUND: Spontaneous resolution of a spinoglenoid notch ganglion cyst (SGC) without surgical treatment has been rarely reported; however, we have encountered this phenomenon occasionally. Therefore, we aimed to describe a case series of consecutive patients with SGC in whom it spontaneously resolved without surgical treatment. METHODS: We retrospectively reviewed 12 patients with magnetic resonance imaging (MRI)-confirmed SGC in whom it resolved without surgical treatment between January 2011 and March 2023. We included patients without abnormally increased signal intensity or muscle atrophy due to denervation from suprascapular neuropathy on MRI. Resolution of the SGC was confirmed via MRI or ultrasound at the follow-up visit, and suprascapular neuropathy was assessed using electromyography and nerve conduction studies when needed. For functional assessments, the visual analog scale for pain and active range of motion of the shoulder were used to compare pre and postresolution follow-ups. RESULTS: Eleven men and 1 woman with a median age of 54.0 years (interquartile range [IQR] 37.0-65.3) were included in this study. The SGCs resolved spontaneously at a median of 13.2 months with an IQR of 8.2-23.0 after initial evaluation using MRI. The SGCs were multiloculated cysts with superior labrum anterior and posterior II-IX lesions, with a median diameter of 2.5 cm (IQR 2.0-2.8). The median visual analog scale for pain (pre-resolution 5.0 [IQR 4.0-7.0] vs postresolution 1.0 [IQR 0.0-1.0], P = .002) and internal rotation at the back (preresolution 8.0 [IQR 7.0-10.3] vs postresolution 7.5 [IQR 7.0-8.0], P = .034) were significantly improved after the resolution. CONCLUSIONS: Surgical treatment may not be necessary in all cases of SGC. Nonsurgical treatment may be a viable option in the absence of suprascapular nerve involvement or superior labrum anterior and posterior-related physical findings.

Surgical management of SLAP lesions: Which technique has better surgical outcomes?

Background: The gold-standard surgical management for superior labral anterior to posterior (SLAP) lesions is unclear. This meta-analysis compares the outcomes of different surgical SLAP lesion management techniques including labral repair, long head of biceps (LHB) tenodesis and LHB tenotomy with consideration to clinical scores, return to sports, re-operation, range-of-motion and patient satisfaction. Methods: PRISMA guidelines were adhered. Web of Science, PubMed, Cochrane Central, Science direct and EMBASE were searched using relevant keywords. Eligible studies were screened, data extracted and synthesised using Review Manager (Version 5.4.1). Bayesian network meta-analysis (NMA) was conducted. Randomised control and clinical trials regarding SLAP lesion management in patients over 18 years old were included. Studies were excluded if patients had concomitant massive tears of the rotator cuff, Bankart lesions or instability of the shoulder. Results: Patient satisfaction with LHB tenodesis was superior to superior labral repair. No difference was demonstrated with respect to ASES score, pain VAS score, return to sports and pre-injury activities, reoperation rate or range-of-motion. LHB tenodesis and LHB tenotomy show no difference in ASES score or post operative deformity in management of SLAP lesions. Discussion: High-quality, standardised randomised control studies between the different surgical techniques is warranted.

Long-term results of arthroscopic repair of type II SLAP lesions in sports: assessment of return to pre-injury playing level and critical risk factors for complication.

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.

Outcomes After Open Latarjet in Patients With or Without SLAP Lesions.

Background: Up to 20% of shoulders with anterior instability are associated with superior labrum anterior-posterior (SLAP) lesions, and they remain untreated after an open Latarjet procedure. SLAP lesions can be responsible for pain and feelings of instability in high-demand patients. Purpose/Hypothesis: The aim of this study was to compare the early functional outcomes and return to sport rates in athletes after the Latarjet procedure with versus without associated SLAP lesions. It was hypothesized that untreated SLAP lesions would not influence clinical results. Study Design: Cohort study; Level of evidence, 3. Methods: Inclusion criteria were athletes with anterior shoulder instability treated with Latarjet procedure, a minimum follow-up of 1 year, and an available preoperative computed tomography arthrogram. We recorded patient characteristics; type of sport; bone loss; Rowe, Single Assessment Numeric Evaluation (SANE), and 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; 5-point pain and satisfaction scores; reported apprehension; and return to sport. Patients with and without a preoperative type 5 SLAP lesion on imaging were compared. Results: Fifty patients were included (mean age, 22 ± 5 years [range, 16-36 years]; mean follow-up, 27 ± 9 months [range, 12-42 months]). Thirty-four patients practiced contact sports, including 20 rugby players. Twelve patients (24%) had a preoperative SLAP lesion. Groups with (+) and without (-) a SLAP lesion were comparable in terms of age, sex, number of instability episodes, type of sport, and glenoid and humeral bone loss. The SLAP+ group had significantly worse outcomes with a lower Rowe score (79 ± 23 vs 91 ± 15; P = .018) and painless rate (50% vs 77%; P = .04). There were no significant differences between the groups in SANE score (SLAP+ vs SLAP-: 80% vs 87%), QuickDASH score (8% vs 8%), return to sport (83% vs 91%), apprehension (79% vs 50%), and reported satisfaction. There was 1 episode of postoperative subluxation in each group. Conclusion: Patients who underwent an open Latarjet procedure with an associated SLAP tear more frequently reported postoperative pain than those without a SLAP lesion. Patients with untreated SLAP tears had significantly lower Rowe scores, although SANE score and return to sport were not significantly different between the groups.

Clinical Outcomes Following Arthroscopic Decompression and Repair versus Repair Alone in Patients with a Concomitant Spinoglenoid Cyst and SLAP Lesion: A Systematic Review.

(1) Background: Patients with a superior-labrum-from-anterior-to-posterior (SLAP) tear associated with a spinoglenoid ganglion cyst have undergone various procedures. The purpose of this study is to evaluate clinical outcomes following arthroscopic treatment in patients with a concomitant spinoglenoid ganglion cyst and SLAP lesion. (2) Methods: This study followed PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines, utilizing the PubMed, EMBASE, Cochrane Library, and Scopus databases. The keywords included shoulder, SLAP, labral tear, spinoglenoid notch, paralabral cyst, arthroscopy, and treatment. (3) Results: A total of 14 articles (206 patients) were included. Repair alone was administered in 114 patients (Group R), and 92 patients underwent additional cyst decompression (Group RD). Both groups showed excellent and similar clinical scores. The rate of the complete resorption of the cyst was 95.5% in Group RD, and 92.2% in Group R. The complication rate was 3.5% in Group RD, and 11.4% in Group R. The reoperation rate was 0% in Group RD, and 5.3% in Group R. (4) Conclusion: Reliable clinical outcomes without serious complications were obtained from the use of both procedures. The decompression of the cyst is a safe method that will alleviate pressure on the suprascapular nerve.

Lesion prevalence and patient outcome comparison between primary and recurrent anterior shoulder instability.

BACKGROUND: The purpose of this study was to compare lesion prevalence and treatment outcomes in patients with primary and recurrent anterior shoulder instability. METHODS: Patients who were admitted to the institution with a diagnosis of anterior shoulder instability and who underwent arthroscopic surgery between July 2006 and February 2020 were retrospectively evaluated. Minimum follow-up duration of the patients was 24 months. The recorded data and magnetic resonance imaging (MRI) of the patients were examined. Patients aged ≥40 years, with a history of shoulder region fracture, inflammatory arthritis, a history of epilepsy, multidirectional instability, nontraumatic dislocation, and off-track lesions were excluded from the study. Shoulder lesions were documented and patient outcome evaluation was made with the Oxford Shoulder Score (OSS) and visual analog scale (VAS). RESULTS: A total of 340 patients were included in the study. The mean age of patients was 25.6 years (±6.49). The recurrent instability group had a significantly higher rate of anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions compared to the primary instability group (40.6% vs. 24.6% respectively) (P = .033). Twenty-five patients (43.9%) had superior labrum anterior and posterior (SLAP) lesions in the primary instability group and 81 patients (28.6%) had SLAP lesions in the recurrent instability group (P = .035). OSS increased for both primary (from 35 [16-44] to 46 [36-48]) (P = .001) and recurrent instability groups (from 33 [6-45] to 47 [19-48]) (P = .001). There was no significant difference between the groups regarding postoperative VAS and OSS scores (P > .05). CONCLUSIONS: Successful results were obtained in patients younger than 40 years with both primary and recurrent anterior shoulder instability after arthroscopic treatment. ALPSA lesion prevalence was higher whereas SLAP lesion prevalence was lower in patients with recurrent instability. Although the postoperative OSS was comparable between the patient groups, the failure rate was higher in the recurrent instability patients.

Prevalence of the anterosuperior capsulolabral anatomical variations and their association with pathologies of the glenoid labrum: a systematic review and meta-analysis.

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.

Type IX Superior Labrum Anterior and Posterior Lesion in a Professional Football Player: A Rare Pattern of Shoulder Instability in a Non-throwing Athlete.

Anterior shoulder instability is the most frequent type of glenohumeral instability, especially among young athletes. Superior labral anterior-posterior (SLAP) injuries involve the superior glenoid labrum where the long head of the biceps tendon (LHBT) inserts. There is still some debate regarding the pathogenesis, clinical presentation, and treatment of these lesions. We report a clinical case of an 18-year-old male professional football player with a rare type IX SLAP lesion. Given the recurrence of instability after prior nonoperative management, surgical treatment was seen as the best option, and a pan-labral arthroscopic repair suture anchor fixation was performed. Three months after undergoing a personalized postoperative rehabilitation program, he was able to return to full sport with the same competitive level, and no recurrent instability or other symptoms were reported throughout the 18-month follow-up period.

Intra-articular soft arthroscopic Latarjet technique as a Bankart-plus procedure for type V superior labrum anterior-posterior lesion: lower rate of instability recurrence and better functional outcomes of a prospective cohort study.

BACKGROUND: Intra-articular soft arthroscopic Latarjet technique (in-SALT) involves augmentation of arthroscopic Bankart repair (ABR) with soft tissue tenodesis of long head of biceps to upper subscapularis. This study was conducted to investigate superiority of outcomes of in-SALT-augmented ABR over those of concurrent ABR and anterosuperior labral repair (ASL-R) in management of type V superior labrum anterior-posterior (SLAP) lesion. METHODS: This prospective cohort study (conducted between January 2015 and January 2022) included 53 patients with arthroscopic diagnosis of type V SLAP lesion. Patients were allocated into 2 consecutive groups: group A of 19 patients managed with concurrent ABR/ASL-R and group B of 34 patients managed with in-SALT-augmented ABR. Outcome measurements included 2-year postoperative pain, range of motion, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) and Rowe instability scores. Failure was defined as frank/subtle postoperative recurrence of glenohumeral instability or objective diagnosis of Popeye deformity. RESULTS: The statistically matched studied groups showed significant postoperative improvement in outcome measurements. However, group B demonstrated significantly better 3-month postoperative visual analog scale score (3.6 vs. 2.6, P = .006) and 24-month postoperative external rotation at 0° abduction (44° vs. 50°, P = .020) and ASES (84 vs. 92, P < .001) and Rowe (83 vs. 88, P = .032) scores. Rate of postoperative recurrence of glenohumeral instability was relatively lower in group B (10.5% vs. 2.9%, P = .290). No Popeye deformity was reported. CONCLUSION: For management of type V SLAP lesion, in-SALT-augmented ABR yielded a relatively lower rate of postoperative recurrence of glenohumeral instability and significantly better functional outcomes compared with concurrent ABR/ASL-R. However, currently reported favorable outcomes of in-SALT should be validated via further biomechanical and clinical studies.

A stabilizing role of the glenoid labrum: the suction cup effect.

BACKGROUND: The glenoid labrum acts as a bumper, deepening glenoid concavity and amplifying the concavity-compression mechanism, and serves as the scapular attachment for glenohumeral ligaments. The role of the posterosuperior labrum in anteroinferior glenohumeral stability, and the role of the anterior labrum in posterior stability has been debated. The purpose of this study was to quantify the contribution of anteroinferior and posterosuperior labral tears to loss of glenohumeral stability in multiple directions. METHODS: Fourteen fresh-frozen cadaveric shoulders were tested on a custom stability ratio measurement apparatus. The peak force that was required to translate the humeral head in anterior, anteroinferior, posterior, and posteroinferior directions was measured under 5 conditions: intact labrum (n = 14), anteroinferior labral tear (n = 7), posterosuperior labral tear (n = 7), combined labral tear (n = 14), and no labrum (n = 14). The stability ratio was defined as the peak translational force divided by the compressive force. Within force-translation curves, we defined the suction cup effect as the force required to release the negative pressure created by an intact labrum. RESULTS: The suction cup effect was usually present with the intact labrum and always disappeared after removal of the labrum for anterior (100% vs. 0%) and posterior (86% vs. 0%) translations (P < .001). After creation of an anteroinferior labral tear, the stability ratio for posterior direction decreased (P < .001) and the suction cup effect disappeared (P < .001). After creation of a posterosuperior labral tear, stability ratios in the anterior and anteroinferior directions decreased (P ≤ .006) and the suction cup effect disappeared (P ≤ .015). The stability ratio for anterior and anteroinferior testing was more diminished by posterosuperior labral tears than anteroinferior labral tears, and the stability ratio for posterior testing was more diminished by anteroinferior labral tears than posterosuperior labral tears. CONCLUSION: Anteroinferior labral tears decreased posterior stability and posterosuperior labral tears decreased anterior and anteroinferior stability, largely because of loss of the suction cup effect.

Superior labrum anterior to posterior lesions: Part 2 - Classification with arthroscopic correlation.

The glenoid labrum deepens the glenoid fossa and allows for the attachment of the long head of the biceps tendon and glenohumeral ligaments, contributing to the stability of the glenohumeral joint. The superior labrum is a common site of labral injury. The acronym SLAP (superior labrum anterior to posterior or anteroposterior) lesion was introduced by Snyder and colleagues in 1990 to describe superior labral tears based on arthroscopic evaluation. This original classification has since been expanded, and there are currently 10 types of SLAP lesions. The article will describe and illustrate the 10 types of SLAP lesions by means of colour illustrations, MRI images and correlative arthroscopy images. A practical approach to the assessment of SLAP lesions will be recommended. Contribution: The illustrated review functions as a crucial radiological guide for both radiologists and orthopaedic surgeons. The combination of illustrations, MR and correlative arthroscopic images enhances the comprehensive understanding of labral pathology. The value of the review lies in the presentation of imaging findings and classification, coupled with findings on arthroscopy. This understanding is vital in guiding orthopaedic management for patients, ensuring appropriate treatment strategies.

Shoulder Magnetic Resonance Arthrography with the Internal and External Rotation Positions of the Humeral Head in the Evaluation of SLAP Lesions.

We aimed to evaluate the diagnostic performance of shoulder MR arthrography (MRA) acquired in the neutral (N), internal rotation (IR), and external rotation (ER) positions of the shoulder to detect SLAP lesions. Three observers evaluated 130 MRAs to detect SLAP lesions and to calculate labral diastasis in this triple-blinded study. Sensitivity was much higher in the ER (92.5-97.5%) than in the N (60-72.5%) and IR (42.5-52.5%) positions, and the specificity of all the reviewers was 100% in all the positions. The diagnostic accuracy was higher in the ER too (97.7-99.2%). The diastasis length was significantly higher in the ER (median = 2.5-2.8 mm) than in the N (1 mm) and IR (0 mm) positions and was also significantly higher in those patients requiring surgery (p = 0.001). The highest inter-rater agreement values were observed in the ER both in SLAP detection (k = 0.982) and the diastasis length evaluation (ICC = 0.962). The diastasis length threshold in the ER that best separated the patients who did and did not require surgery was 3.1 mm (AUC = 0.833). In 14.6% of the cases, ER enabled the detection of SLAP lesions not identified in the N position. MRA with the ER improves the diagnosis of SLAP lesions and, together with the IR position, provides additional dynamic information about the diastasis of the lesions. It is recommended to perform additional ER and IR scans in the shoulder MRA protocol.

GIRD syndrome in male handball and volleyball players: Is the decrease of total range of motion the turning point to pathology?

BACKGROUND: Adaptations in glenohumeral range of motion may affect overhead athletes and lead to shoulder pathologies. OBJECTIVE: The purpose of this study was to evaluate glenohumeral internal rotation deficit (GIRD) and postero-superior impingement among male handball and volleyball players and the relationship between these pathologies and training level (amateur vs. professional), position (attack vs. no attack), experience (> 5 years vs. < 5 years) and sports. METHODS: Sixty-seven handball players and 67 volleyball players with a mean age of 25 [± 5] years were included. The range of motion including external and internal rotation in 90∘ abduction of the dominant and non-dominant shoulder was measured of each examined athlete. Visual analogue scale, disabilities of the shoulder and hand score, constant score and subjective shoulder value were recorded. The athletes were examined for postero-superior impingement and abduction force was measured with an isokinetic dynamometer. RESULTS: Internal rotation was significantly lower and external rotation was significantly greater in the dominant arm for both sports. 72% presented with GIRD. GIRD was more prevalent in athletes active for > 5 years (odds ratio (OR) 3), in those training > 3 times per week (OR 1.4) and in handball players (OR 2.7). 24% presented with postero-superior impingement. Players active for > 5 years (OR 1.22), professionals (OR 1.14), volleyball players (OR 1.19), offensive players (OR 2.2) and athletes with GIRD > 10∘ (OR 1.5) showed a higher prevalence of postero-superior impingement. CONCLUSION: GIRD is a common phenomenon in handball and volleyball players. Offensive players are frequently suffering from postero-superior impingement. GIRD > 10∘ leads in nearly 75% of the athletes to a decrease of total range of motion and a high rate of postero-superior impingement. Thus, a decreased range of motion seems to be the turning point from adaptation to pathology. Therefore, regular controls of range of motion and countermeasures by means of stretching the posterior shoulder joint should be integrated in the training content.

The middle glenohumeral ligament: a classification based on arthroscopic evaluation.

BACKGROUND: Although middle glenohumeral ligament (MGHL) variations have been shown in the literature, their clinical effect and relationship with intra-articular pathologies have yet to be revealed, except for the Buford complex. This study was designed to classify MGHL and to reveal its relationship with clinical pathologies. METHODS: A total of 843 consecutive shoulder arthroscopies were evaluated retrospectively, and a classification system was proposed for MGHL with regard to its structure and its relation to the anterior labrum. The associations of each MGHL type with superior labrum anterior-posterior (SLAP) lesions, subscapularis tears, and anterior instability were investigated. RESULTS: MGHL variations were grouped into 6 types according to the classification. A significant difference in favor of type 6 MGHL (Buford complex) was observed in the distribution of SLAP lesions (P < .001). There was no significant difference between MGHL types and the distribution of anterior instability history (P = .131) and subscapularis tears (P = .324). CONCLUSION: SLAP lesions accompany type 6 MGHLs (Buford complex) significantly more frequently than other types. There is also a negative relation between the anterior instability and thicker MGHL variants.

Biceps Tenodesis Versus Superior Labral Anterior and Posterior (SLAP) Lesion Repair for the Treatment of SLAP Lesion in Overhead Athletes: A Systematic Review and Meta-analysis.

BACKGROUND: Superior labral anterior and posterior (SLAP) lesions are common injuries in overhead athletes. As a surgical treatment for SLAP lesions, SLAP repair has been traditionally performed. Recently, biceps tenodesis has been performed as an alternative treatment option; however, there is no review for outcome comparisons between these 2 procedures in overhead athletes. PURPOSE: The aim of this study was to compare the outcomes of SLAP repair versus biceps tenodesis, especially in overhead athletes with SLAP lesions. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: An electronic literature search was performed in Medline, Embase, Scopus, and the Cochrane Library. The studies were appraised using the Methodological Index for Non-randomized Studies (MINORS) tool. Studies that had a minimum follow-up of 2 years, included only patients with SLAP lesions without other major shoulder pathologies, and included only patients who engaged in overhead sports were included. The functional outcomes of the American Shoulder and Elbow Surgeons (ASES) score, rate of return to sport, rate of return to preinjury level of sport, and complication rate were subjected to meta-analysis. RESULTS: A total of 332 articles were identified, and 13 were included in the systematic review. Even though the postoperative ASES scores were slightly higher in the biceps tenodesis group than in the SLAP repair group, no statistically significant differences were found between the groups (biceps tenodesis, 95% CI = 91.71-96.75, I2 = 0.00; SLAP repair, 95% CI = 85.47-94.46, I2 = 16.3; P = .085) The rate of return to sport and the return to preinjury level of sport were slightly higher in the biceps tenodesis group than in the SLAP repair group; however, in meta-analysis these factors did not reach statistical significance (return to sport: biceps tenodesis, 95% CI = 0.66-0.91, I2 = 0.00; SLAP repair, 95% CI = 0.68-0.93, I2 = 70.23; P = .94) (return to preinjury level of sport: biceps tenodesis, 95% CI = 0.61-0.89, I2 = 17.78; SLAP repair, 95% CI = 0.53-0.82, I2 = 58.07; P = .37). The biceps tenodesis group showed a lower complication rate compared with the SLAP repair group without statistical significance (biceps tenodesis, 95% CI = 0.013-0.145, I2 = 0.00; SLAP repair, 95% CI = 0.049-0.143, I2 = 0.00; P = .25). CONCLUSION: The results of biceps tenodesis, compared with SLAP repair, were not inferior in the surgical treatment of overhead athletes with SLAP lesions with regard to the ASES score, rate of return to sport, rate of return to preinjury level of sport, and complication rate. Further high-level, randomized controlled studies are needed to confirm this result.

Posterior repair of isolated type 2 superior labrum anterior-posterior lesion prevents external rotation deficiency: long-term outcome study.

PURPOSE: This study aimed to evaluate the outcomes of arthroscopic type 2 superior labrum anterior-posterior (SLAP) lesion repair in the general population and compare clinical outcomes according to patient age and repair site. METHODS: Between 2005 and 2018, patients who underwent arthroscopic repair for isolated type 2 SLAP lesions were retrospectively reviewed. Baseline characteristics, pre- and postoperative [1-year and > 2-year (final)] shoulder range-of-motion, and functional scores, comprising the pain visual analogue scale (PVAS), functional VAS, and American Shoulder and Elbow Surgeons (ASES) score, were evaluated. Return to overhead activities and subjective satisfaction were assessed at the final follow-up, and patients were divided by age [group YB (< 40 years] and group OB (≥ 40 years)] and repair site [group P (only posterior labrum repair) and group AP (anterior and posterior labrum repair)]. Overall patient outcomes were analysed and compared between groups. RESULTS: This study included 54 patients (45 men) with a mean age of 37.1 ± 8.3 years. The mean follow-up was 90.8 ± 51.3 months. Two patients experienced early failure, and one patient had a ruptured biceps tendon during the follow-up period. Final functional scores improved compared to their preoperative scores in all patients, except three (all p < 0.001). Fifty patients (98.0%) were satisfied, and 39 patients (76.5%) were able to perform overhead sports without restriction. In 25 patients who attended more than 7 years of follow-up (mean, 11.3 ± 2.7 years), 21 patients (84%) had an ASES score ≥ 80, and all patients had PVAS ≤ 2. There was no significant difference in clinical outcomes between groups YB and OB. The final median external rotation was significantly more restricted in group AP than in group P (40 [25-65] vs. 60 [50-70], p = 0.002). CONCLUSION: Arthroscopic type 2 SLAP repair induced good short- and long-term clinical outcomes, return to overhead activities, and subjective satisfaction in the general population, regardless of age, due to the careful evaluation of patient history, physical examination, and imaging studies. However, performing only posterior repair seems sufficient since anterior labral SLAP lesion repair can limit ER. Isolated type 2 SLAP lesion posterior repair only is, thus, recommended to reduce external rotation deficit risk and increase satisfaction, regardless of patient age. STUDY DESIGN: Case series. LEVEL OF EVIDENCE: Level IV.

Surgical Management of Superior Labral Tears in Athletes: Focus on Biceps Tenodesis.

Superior labrum anterior-posterior (SLAP) lesions are common in overhead athletes. Though some patients have asymptomatic lesions, many tears cause pain and diminished athletic performance. Accurate diagnosis of SLAP lesions can be challenging as the sensitivity and specificity of both the physical exam and advanced imaging is questionable. Management is also difficult, as treatment can be life-altering or career-ending for many athletes. If first-line nonoperative treatment fails, surgical options may be considered. The optimal surgical management of SLAP lesions in athletes is debated. Historically, return to play (RTP) rates among athletes who have undergone arthroscopic SLAP repair have been unsatisfactory, prompting clinicians to seek alternate surgical options. Biceps tenodesis (BT) has been postulated to eliminate biceps tendon-related pain in the shoulder and is increasingly used as a primary procedure for SLAP lesions. The purpose of this text is to review the current literature on the surgical management of SLAP lesions in athletes with an emphasis on the role of BT.

Arthroscopic labral repair with all-suture anchors: a magnetic resonance imaging retrospective study with a 2.5-year follow-up.

Aim To evaluate radiological and clinical outcomes of a case series of patients affected by glenohumeral instability (Bankart lesion) or superior labrum tear from anterior to posterior (SLAP) lesions treated by arthroscopic repair using all-suture anchors. Methods Patients were operated by a single surgeon at a single Institution. Exclusion criteria were chondral lesions of the glenoid, rotator cuff lesions, previous surgery at the index shoulder, or a bony Bankart lesion. Position and numbers of anchors used depended on the dimension and type of lesion. The DASH (Disability of the Arm, Shoulder and Hand) and Constant scores were used for subjective and clinical evaluation at follow-ups (FUs); also, at 1-year FU, MRI scan was obtained to evaluate bone reaction to the implanted devices. Results Fifty-four patients were included. A mean of 2.7 devices per patient (145 in total) were implanted. Mean FU was 30 (range 12 - 48) months. No patient reported recurrent instability, nor hardware-related complications were registered. MRI analyses showed that 119 (82%) implants did not alter surrounding bone (grade 0), 26 (18%) implants were surrounded by bone oedema (grade 1), while no bone tunnel enlargement nor a bone cyst (grade 2 or 3, respectively) were registered. Conclusion This study confirmed the efficacy and safety of a specific all-suture anchor system in the arthroscopic repair of the glenoid labrum for glenohumeral instability or a SLAP lesion. In the short- and mid-term period, these devices were associated with good clinical and radiological outcomes without clinical failures or reaction at bone-device interface.
