Bethell MA, Hurley ET, Rowe D, Crook BS, Cabell G, Klifto CS, Lau BC, Dickens JF, Taylor DC. Type V superior labrum anterior to posterior repair: a systematic review. J Shoulder Elbow Surg 2024; 33:e443-e450. [PMID: 38522776 DOI: 10.1016/j.jse.2024.01.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 01/18/2024] [Accepted: 01/30/2024] [Indexed: 03/26/2024]
Abstract
BACKGROUND The purpose of this study is to systematically review the evidence in the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following type V superior labrum anterior to posterior (SLAP) repair. METHODS Two independent reviewers performed a literature search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, utilizing the EMBASE, MEDLINE, and the Cochrane Library Databases. Studies were included if they had clinical outcomes on the patients undergoing type V SLAP repair. Statistical analysis was performed using SPSS (IBM, Armonk, NY, USA). A P value of <.05 was considered to be statistically significant. RESULTS Our review found 13 studies, including 451 shoulders meeting our inclusion criteria. The majority of patients were males (89.3%), with an average age of 25.9 years (range 15-58) and a mean follow-up of 53.8 months. The Rowe score was the most utilized functional outcome score, with a weighted mean of 88.5. Additionally, the mean Constant score was 91.0, the mean American Shoulder and Elbow Surgeons score was 88.3, the mean subjective shoulder value score was 85.5%, and the mean visual analog scale pain score was 1.2. The overall rate of return to play was 84.8%, with 80.2% returning to the same level of play. The overall reoperation rate was 6.1%, with a recurrent dislocation rate of 8.2%. In the studies comparing type V SLAP and isolated Bankart repair, there were statistically insignificant differences in visual analog scale pain scores (mean difference; 0.15, 95% confidence interval, -0.13 to 0.44, I2 = 0%, P = .29) and recurrence rates (risk ratio; 1.38, 95% confidence interval, 0.88-2.15, I2 = 0%, P = .16). CONCLUSION Arthroscopic repair of type V SLAP tears results in excellent functional outcomes, with high return to play rates in athletes. There are low rates of reoperations and recurrent dislocations. Additionally, in comparison to an isolated Bankart repair, SLAP repair does not increase recurrence rates or postoperative pain.

Skeletal Radiol 2024:10.1007/s00256-024-04708-1. [PMID: 38758391 DOI: 10.1007/s00256-024-04708-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 05/03/2024] [Accepted: 05/12/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE Although SLAP-5 lesions are associated with recurrent dislocations, their causes and pathomechanisms have not been fully elucidated. This study aimed to investigate the association between SLAP-5 lesions and scapular morphology in traumatic anterior shoulder instability (ASI). We hypothesized that there may be a relationship between SLAP-5 lesions and scapular morphology in traumatic ASI patients. MATERIALS AND METHODS The study included 74 patients with isolated Bankart lesions and 69 with SLAP-5 lesions who underwent arthroscopic labral repair for ASI. Critical shoulder angle (CSA) was measured on the roentgenograms, while glenoid inclination (GI) and glenoid version (GV) were measured on magnetic resonance imaging (MRI) by two observers in two separate sessions blinded to each other. Both groups were compared in terms of CSA, GI, and GV. RESULTS The mean ages of Bankart and SLAP-5 patients were 28.4±9.1 and 27.9±7.7 (P=0.89), respectively; their mean CSA values were 33.1°±2.6° and 28.2°±2.4°, respectively (P<0.001). The ROC analysis's cut-off value was 30.5°, with 75.0% sensitivity and 76.7% specificity (AUC = 0.830). SLAP-5 lesions were more common on the dominant side than isolated Bankart lesions (P=0.021), but no difference was found between the groups in terms of GI and GV (P=0.334, P=0.081, respectively). CONCLUSIONS In ASI, low CSA values appeared to be related to SLAP-5 lesions, and the cut-off value of CSA for SLAP lesion formation was 30.5° with 75.0% sensitivity and 76.7% specificity. Scapula morphology may be related to the SLAP-5 lesions, and CSA can be used as an additional parameter in provocative diagnostic tests and medical imaging techniques for the detection of SLAP lesions accompanying Bankart lesions. LEVEL OF EVIDENCE III retrospective case-control study.

Abstract
BACKGROUND Pain is a common presentation after glenohumeral labral injuries. However, the source of that pain is undetermined. PURPOSE/HYPOTHESIS We aimed to determine if there is a differential expression of nerve fibers around the glenoid labrum and if torn labra have increased neuronal expression compared with untorn labra (rotator cuff repair labra). We hypothesized that the superior labrum would have a higher concentration of neurofilament than would the rest of the labrum and that the concentration of neurofilament would increase at the site of a labral tear. STUDY DESIGN Descriptive laboratory study. METHODS Seven labra were sampled at the 3-, 5-, 9-, and 12-o'clock positions during total shoulder arthroplasty. Samples were also collected at the 3-, 5-, and 12-o'clock positions during rotator cuff repair (16 labra), anterior labral repair (6 labra), type II superior labral anterior to posterior (SLAP) repair (4 labra), and capsular release for idiopathic capsulitis (5 labra). Sections were immunostained with antibodies to neurofilament, a specific neuronal marker that is used to identify central and peripheral nerve fibers, and the concentration and intensity of immunostained-positive cells assessed. RESULTS The concentration of neurofilament staining was similar in the superior, anterior, posterior, and inferior glenoid labrum in untorn labra (8 neurofilament expressing cells per square millimeter; P = .3). Torn labra exhibited a 3- to 4-fold increase in neuronal expression, which was isolated to the location of the tear in SLAP (P = .09) and anterior labral tears (P = .02). The concentration of neurofilament expressing cells in torn glenoid labrum samples was comparable that in with the glenoid labrum of adhesive capsulitis samples (P = .7). CONCLUSION This study supports the hypothesis that after a tear of the anterior or superior labrum the labrum in that region becomes populated with new nerves fibers and that these fibers may be responsible for the pain noted by patients with superior (SLAP) and/or anterior labral (Bankart) tears. CLINICAL RELEVANCE This study suggests that neural infiltration contributes to the pain experienced by patients with labral tears. It may help with patient education and direct future management of labral lesions.

Abstract
Background: Favorable outcomes have been reported regarding postoperative shoulder pain and function after repair of anteroinferior (Bankart) glenohumeral labral tears. However, the outcomes of patients after repair of isolated superior labral anterior-posterior (SLAP) tears are a contentious topic. The authors have also anecdotally noted that patients evaluated with labral tears complained of numbness and tingling in their ipsilateral hand. Purpose: To determine if there is a difference in the temporal outcomes of shoulder pain and hand paresthesia in patients with SLAP tears versus Bankart tears after arthroscopic repair. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 66 consecutive patients who underwent arthroscopic labral repair at a single institution between August 2018 and February 2021. The prevalence and magnitude of shoulder pain as well as numbness and tingling of the hand were assessed using questions from the L’Insalata Shoulder Questionnaire and the Boston Carpal Tunnel Questionnaire preoperatively and at 1 week, 6 weeks, 12 weeks, and 6 months after surgery. Results: Preoperatively, patients with SLAP lesions reported a higher prevalence of shoulder pain during sleep compared with those with Bankart tears (P < .05). Postoperatively, patients who underwent SLAP repair reported a larger proportion and more severe magnitude of shoulder pain during rest, overhead activities, and sleep compared with those who underwent Bankart repair (P < .05). Only patients who underwent Bankart repair reported improvements in the prevalence and magnitude of their shoulder pain during rest, overhead activities, and sleep by 6 months postoperatively compared with preoperative levels (P < .05). Preoperatively, 30% of patients with Bankart repairs and 40% of patients with SLAP repairs reported hand tingling, while 35% and 50%, respectively, reported hand numbness. The prevalence and magnitude of hand tingling and numbness were not significantly different between groups at any time point. Conclusion: Study results indicated that patients who underwent SLAP repair experienced worse shoulder pain outcomes compared with those who underwent Bankart repair using the same anchor and surgical technique. Only patients who underwent Bankart repair reported improvements in their hand numbness after surgery. Therefore, labral tear location does matter with respect to shoulder pain and hand numbness.

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 The glenoid labrum can be torn in 1 or more locations. It is undetermined if the location of the labral tear alters patient outcomes after repair. Methods A total of 252 labral repair cases were retrospectively reviewed using prospectively collected patient-ranked outcomes and examiner-determined assessments preoperatively, at 1 week, 6 weeks, 24 weeks, and at a minimum of 2 years after surgery. Results Preoperatively, patients who underwent a superior labral repair reported worse pain at night and during activity than patients who subsequently underwent an isolated anterior labral repair or a combined anterior and superior labral repair (P < .05). After surgery, patients who underwent an isolated superior labral repair reported more severe pain at night and during activity, increased stiffness, and less satisfaction with their shoulder than patients who had an isolated anterior (P < .05) or a combined anterior and superior labral repair (P < .05). Conclusions Patients with isolated superior labral repairs have more pain both before and after repair than patients who undergo anterior or anterior and superior labral repairs.

Abstract
OBJECTIVES This study aims to compare the clinical results of patients with traumatic isolated Bankart lesions and type V superior labrum anterior to posterior (SLAP) lesions after arthroscopic repair. PATIENTS AND METHODS Patients who underwent arthroscopic repair for traumatic anterior glenohumeral instability were evaluated retrospectively between December 2014 and January 2019. Fifty-one patients (49 males, 2 females; mean age 25 years; range, 18 to 36 years) without bone defects affecting >20% of the glenoid fossa, off-track engaging Hills-Sachs lesions, multidirectional instability, or ligamentous laxity were included in the study. Group 1 had 31 patients with isolated Bankart lesions and group 2 had 20 patients with type V SLAP lesions. There were only two female patients in group 1 and all patients were male in group 2. The mean age was 25 years (range, 18 to 36 years) in group 1 and 25 years (range, 19 to 35 years) in group 2. Rowe, Constant, and Western Ontario Shoulder Instability (WOSI) scoring systems were used to evaluate the clinical outcomes of the patients preoperatively and at the last follow-up. RESULTS The mean follow-up time was 32 months (range, 12 to 48 months) in group 1 and 28.5 months (range, 12 to 42 months) in group 2. There were no statistically significant differences between the two groups in terms of the number of shoulder dislocations before the surgery, mean age at the time of surgery, and the mean time from the first dislocation to surgical treatment. When the Rowe, Constant, and WOSI scores were evaluated preoperatively and at the last follow-up, there were statistically significant changes within, but not between, the two groups. CONCLUSION In type V SLAP lesions, the affected and repaired labrum surface area is larger than isolated Bankart lesions. However, as a result of appropriate surgical treatment, the affected surface area does not have a negative effect on clinical outcomes, and similar clinical results can be obtained in patients with type V SLAP lesions compared to patients with isolated Bankart lesions.

Abstract
The hypermobility of the glenohumeral joint accounts for its anatomic predisposition for instability and dislocation. The stability of the shoulder joint is dependent on static and dynamic soft tissue structures, among which is the labrum. Circumferential labral tears are a rare pathological entity of shoulder instability that have not been commonly reported in the literature. A detailed history and physical examination are crucial for accurate diagnosis since MRIs have a poor sensitivity. A 40-year-old male patient with a history of atraumatic recurrent left shoulder subluxations for 6 years. On physical examination, there was no evidence of motor or sensory deficit. MR images were suggestive of Hills-Sachs lesion with intact rotator cuffs. Pan-labral tear repair via arthroscopy presents a unique challenge, even for the skilled orthopedic surgeon. Hence, the repair demands accessory portals and percutaneous techniques for the adequate placement of anchors. The purpose of this case is the rare presentation of a pan-labral tear repaired arthroscopically.

Abstract
PURPOSE To evaluate preoperative diagnostic rates for panlabral tear using imaging studies or physical examinations and to evaluate clinical outcomes after arthroscopic stabilization procedures with 2 different patient surgical positions. METHODS Patients who underwent arthroscopic stabilization for recurrent anterior shoulder instability with panlabral tear and were followed up for at least 2 years were included. A panlabral tear was defined as labral tear involving at least 270° of the glenoid surface on arthroscopic examination. All patients underwent preoperative magnetic resonance (MR) imaging or MR arthrography and physical examinations including anterior apprehension, posterior jerk, and compressive rotation tests. The clinical outcomes were assessed by the American Shoulder and Elbow Surgeons, Rowe, and visual analog scale for pain scores, and recurrence rate. According to patient position during surgery, patients were divided into group I (beach chair position) and group II (lateral decubitus position). RESULTS Forty-eight patients (24 in group I and 24 in group II) were enrolled. Preoperative MR imaging or MR arthrography detected only 18.8% of panlabral tears. No patient had positive findings on all 3 physical examination tests for panlabral tear. Clinical outcomes were significantly improved after operation (American Shoulder and Elbow Surgeons score: 58.4 ± 6.2 preoperatively, 85.2 ± 6.4 at the final, P < .001; Rowe score: 49.0 ± 12.2 preoperatively, 86.8 ± 9.1 at the final, P < .001) and postoperative recurrence was occurred in 1patient (2%). No differences were found in clinical outcomes and recurrence rate (4% vs 0%) according to patient positioning, despite the larger number of suture anchors used in group II (6.2 ± 1.5 in group I, 7.6 ± 1.1 in group II, P < .001). CONCLUSIONS It remained difficult to preoperatively diagnose panlabral tear using standard physical examinations and imaging studies. Nevertheless, arthroscopic stabilization procedures for patients with panlabral tear provided satisfactory clinical outcomes with a low recurrence rate. Patient position during surgery did not alter clinical outcomes and recurrence rate, despite the use of different numbers of suture anchors.

Abstract
BACKGROUND The literature has reported debatable diagnostic accuracy of clinical provocative tests for a type II superior labral anteroposterior (SLAP) lesion, especially in the context of a type V SLAP (concurrent Bankart and type II SLAP) lesion. This study was conducted to determine whether the investigated provocative tests offer reliable predictive values in the diagnosis of type II SLAP lesions in patients with recurrent anterior glenohumeral (GH) instability. METHODS This prospective case-control study carried out between September 2014 and September 2018 included 51 patients with post-traumatic recurrent anterior GH instability. Patients were prospectively evaluated for type II SLAP lesions by 9 provocative tests: Jobe relocation test, abduction-external rotation test, anterior slide test, biceps load test I, biceps load test II, pain provocation test, labral tension test, crank test, and the O'Driscoll dynamic labral shear test. The results of these tests were compared with findings of diagnostic arthroscopic GH examinations (control). RESULTS Statistical analysis revealed the mean age of the studied group to be 26.1 ± 7.56 years, with male predominance (50 patients; 98.04%). Arthroscopic examination revealed a Bankart lesion in isolation and in association with a type II SLAP lesion (ie, a type V SLAP lesion) in 15 (29.4%) and 36 (70.6%) patients, respectively. The anterior slide test yielded the highest positive and lowest negative likelihood ratios (2.91 and 0.52, respectively). CONCLUSION Except for the anterior slide test, which can be validated for the clinical diagnosis of type II SLAP lesions in patients with traumatic recurrent anterior GH instability, the investigated tests offer poor predictive values and should be cautiously used in clinical practice.

Abstract
Background Arthroscopic repair of combined Bankart/superior labral anteroposterior (SLAP) lesions is commonly performed to treat anterior shoulder instability, the clinical outcomes of which have not been widely studied. Purpose To compare the clinical outcomes for arthroscopic repair of combined Bankart/SLAP lesions in the treatment of anterior shoulder instability and to ascertain whether it is inferior to isolated Bankart repair. Study Design Systematic review; Level of evidence, 3. Methods A systematic review of the literature was performed through use of the MEDLINE, EMBASE, and Cochrane Library databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Study bias was assessed using the MINORS (Methodological Index for Non-Randomized Studies) scoring system. Randomized controlled trials, prospective or retrospective cohort studies, and case-control studies were included, whereas systematic reviews, literature reviews, conference abstracts, case reports, case series, and non-peer-reviewed studies were excluded to guarantee the quality of the study. Data on outcomes including recurrence rate, functional scores, and range of motion (ROM) were pooled, with statistical analysis performed. A P value of <.05 was considered statistically significant. Results The review included 7 studies with a total of 520 patients. The pooled recurrence rate after combined Bankart/SLAP repair was 6.47% (9/139). Significant improvements of postoperative versus preoperative functional scores were observed, including a reduction in the visual analog scale score for pain (mean ± SD: 0.99 ± 1.36 vs 4.13 ± 2.26; P < .00001) and an increase in mean Rowe score (89.56 ± 11.46 vs 43.16 ± 8.87; P < .00001) and mean Constant score (91.41 ± 7.57 vs 59.70 ± 5.63; P < .00001). In terms of ROM, no reduction was found in external rotation (66.56° ± 13.33° vs 67.22° ± 14.27°; P = .21), and a significant increase in abduction was found (157.67° ± 4.11° vs 144.18° ± 8.28°; P < .00001). No statistically significant difference was found between arthroscopic repair of combined Bankart/SLAP lesions and isolated Bankart repair regarding recurrence rate, functional scores, or ROM. Conclusion Of the pooled data, patients who underwent arthroscopic repair of combined Bankart/SLAP lesions in treatment of anterior shoulder instability showed a low recurrence rate, favorable functional scores, and no significant restriction on ROM, all of which were not significantly worse than outcomes of isolated Bankart repair. Therefore, combined repair was proven to be a viable option for extensive labral lesions.

Abstract
BACKGROUND The purpose of this prospective study is to compare and correlate the clinical results of arthroscopic repair of a combined anteroinferior and superior labral lesion with those of an isolated anteroinferior labral lesion or type II superior labral tear from anterior to posterior (SLAP) lesion. METHODS A comparative study involving patients who underwent arthroscopic labral repairs in a tertiary hospital between 2010 and 2014 was conducted. A total of 96 patients were divided into three groups: Group A consisted of 61 patients with the anteroinferior labral lesion, group B consisted of 16 patients with the type II SLAP lesion, and group C consisted of 19 patients with the combined anteroinferior and superior labral lesion. Patient demographics, preoperative and postoperative pain scores, shoulder functional scores (Constant Shoulder Score, UCLA (University of California at Los Angeles) Shoulder Score, and Oxford Instability Score), and shoulder ranges of motion were measured and compared. RESULTS Except that patients from group B were generally older (28.8 vs. 22.2 for group A and 22.0 for group C, p = 0.04) at the time of surgery, no significant differences exist among the three groups in patient demographics and relevant clinical data. Preoperative and 2-year postoperative clinical outcomes, as well as the improvements, were comparable among the three groups. Low failure rates were observed for all three groups (6% vs. 10% vs. 11%, p = 0.999). CONCLUSIONS Patients with the type II SLAP lesion underwent surgery at an older age. With appropriate surgical procedures, equivalent postoperative results can be expected for combined anteroinferior and superior labral lesion repair compared to isolated labral lesion repair.

Abstract
BACKGROUND Tears of the glenoid labrum are common after dislocation of the glenohumeral joint. The outcome for healing or surgical reconstruction of the glenoid labrum relies on the extent of its vascularization. This study aims to evaluate the glenoid labrum blood supply and to determine its regional vascularity. MATERIALS AND METHODS A total of 140 shoulders (30 male and 40 female cadavers) were examined: mean age 81.5 years, range 53-101 years. All blood vessels around the glenohumeral joint were dissected and recorded. Ten specimens with the glenoid labrum and fibrous capsule attached were randomly selected and detached at the glenoid neck and subjected to decalcification. Sections (10-20 μm) were cut through the whole thickness of each specimen from the centre of the glenoid fossa perpendicular to the glenoid labrum at 12 radii corresponding to a clock face superimposed on the glenoid. Sections were stained using haematoxylin and eosin and then examined. RESULTS The blood supply to the glenoid labrum is by direct branches from the second part of the axillary artery, subscapular, circumflex scapular and anterior circumflex humeral and posterior circumflex humeral arteries, as well as branches of muscular arteries supplying the surrounding muscles. CONCLUSION This study shows that the glenoid labrum has a rich blood supply suggesting that, regardless of the types of the glenoid labrum lesions or their management, an excellent outcome for glenoid labrum healing and joint stability is possible. The observations also suggest that the blood supply to the glenoid labrum is sufficient, enabling its reattachment.

Abstract
BACKGROUND The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. METHODS We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. RESULTS Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). CONCLUSIONS Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed.
