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.
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).
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).
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.
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.
Background:
Data regarding risk factors for revision surgery after superior labral anterior-posterior (SLAP) repair are limited to institutional series.
Purpose:
To define risk factors for revision ...surgery after SLAP repair among patients in a large national database.
Study Design:
Case-control study; Level of evidence, 3.
Methods:
A national insurance database was queried for patients undergoing arthroscopic SLAP repair (Current Procedural Terminology CPT code 29807) for the diagnosis of a SLAP tear. Patients without a CPT modifier for laterality were excluded. Revision surgery was defined as (1) subsequent ipsilateral SLAP repair (CPT 29807), (2) ipsilateral arthroscopic debridement for the diagnosis of a SLAP tear (CPT 29822 or 29823, with diagnosis code 840.7), (3) subsequent ipsilateral arthroscopic biceps tenodesis (CPT 29828), (4) subsequent ipsilateral open biceps tenodesis (CPT 23430), and (5) subsequent biceps tenotomy (CPT 23405). Multivariable binomial logistic regression analysis was performed to identify risk factors for revision surgery after SLAP repair, including patient demographics/comorbidities, concomitant diagnoses, and concomitant procedures performed. Odds ratios (ORs), 95% CIs, and P values were calculated. The estimated financial impact of revision surgery was also calculated.
Results:
There were 4751 patients who met inclusion and exclusion criteria. Overall, 121 patients (2.5%) required revision surgery after SLAP repair. Regression analysis identified numerous risk factors for revision surgery, including age >40 years (OR, 1.5; 95% CI, 1.2-1.8; P = .045), female sex (OR, 1.5; 95% CI, 1.3-1.8; P = .010), obesity (OR, 1.8; 95% CI, 1.5-2.2; P = .001), smoking (OR, 2.0; 95% CI, 1.6-2.4; P < .0001), and diagnosis of biceps tendinitis (OR, 3.5; 95% CI, 3.0-4.2; P < .0001) or long head of the biceps tearing (OR, 5.1; 95% CI, 4.1-6.3; P < .0001) at or before the time of surgery. Concomitant rotator cuff repair and distal clavicle excision were not significant risk factors for revision surgery. The cost of revision surgery averaged almost $9000.
Conclusion:
Risk factors for revision surgery after SLAP repair include age >40 years, female sex, obesity, smoking, and diagnosis of biceps tendinitis or long head of the biceps tearing. The diagnosis of biceps tendinitis (OR, 3.5) or long head of the biceps tearing (OR, 5.1) at or before the time of surgery was an especially significant risk factor for revision surgery. The high cost of revision surgery highlights the importance of appropriate indications to avoid the need for subsequent procedures.
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.

Background:
Superior labrum anterior-posterior (SLAP) lesions and anterior instability are common causes of shoulder pain and dysfunction among active-duty members of the United States military. ...However, little data have been published regarding the surgical management of type V SLAP lesions.
Purpose:
To compare the outcomes of arthroscopic-assisted subpectoral biceps tenodesis and anterior labral repair with those of arthroscopic SLAP repair (defined as contiguous repair spanning from the superior labrum to the anteroinferior labrum) for type V SLAP tears in active-duty military patients younger than 35 years.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
All consecutive patients from January 2010 to December 2015 who underwent arthroscopic SLAP repair or combined biceps tenodesis and anterior labral repair for a type V SLAP lesion with a minimum 5-year follow-up were identified. The decision to perform type V SLAP repair versus combined biceps tenodesis and anterior labral repair was based on the condition of the long head of the biceps tendon (LHBT). Labral repair was performed in patients who had a type V SLAP tear with an otherwise clinically and anatomically healthy LHBT. Combined tenodesis and repair was performed in patients with evidence of LHBT abnormalities. Outcomes including the visual analog scale (VAS) score, the Single Assessment Numeric Evaluation (SANE) score, the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Rowe instability score, and range of motion were collected preoperatively and postoperatively, and scores were compared between the groups.
Results:
A total of 84 patients met the inclusion criteria for the study. All patients were active-duty service members at the time of surgery. A total of 44 patients underwent arthroscopic type V SLAP repair, and 40 patients underwent anterior labral repair with biceps tenodesis. The mean follow-up was 102.59 ± 20.98 months in the repair group and 94.50 ± 27.11 months in the tenodesis group (P = .1281). There were no significant differences in preoperative range of motion or outcome scores between the groups. Both groups experienced statistically significant improvements in outcome scores postoperatively (P < .0001 for all); however, compared with the repair group, the tenodesis group reported significantly better postoperative VAS (2.52 ± 2.36 vs 1.50 ± 1.91, respectively; P = .0328), SANE (86.82 ± 11.00 vs 93.43 ± 8.81, respectively; P = .0034), and ASES (83.32 ± 15.31 vs 89.90 ± 13.31, respectively; P = .0394) scores. There were no differences in the percentage of patients who achieved the minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state for the SANE and ASES between the groups. Overall, 34 patients in each group returned to preinjury levels of work (77.3% vs 85.0%, respectively; P = .3677), and 32 patients (72.7%) in the repair group and 33 patients (82.5%) in the tenodesis group returned to preinjury levels of sporting activity (P = .2850). There were no significant differences in the number of failures, revision surgical procedures, or patients discharged from the military between the groups (P = .0923, P = .1602, and P = .2919, respectively).
Conclusion:
Both arthroscopic-assisted subpectoral biceps tenodesis combined with anterior labral repair and arthroscopic SLAP repair led to statistically and clinically significant increases in outcome scores, marked improvements in pain, and high rates of return to unrestricted active duty in military patients with type V SLAP lesions. The results of this study suggest that biceps tenodesis combined with anterior labral repair produces comparable outcomes to arthroscopic type V SLAP repair in active-duty military patients younger than 35 years.
As part of their social sound repertoire, migrating humpback whales (Megaptera novaeangliae) perform a large variety of surface‐active behaviors, such as breaching and repetitive slapping of the ...pectoral fins and tail flukes; however, little is known about what factors influence these behaviors and what their functions might be. We investigated the potential functions of surface‐active behaviors in humpback whale groups by examining the social and environmental contexts in which they occurred. Focal observations on 94 different groups of whales were collected in conjunction with continuous acoustic monitoring, and data on the social and environmental context of each group. We propose that breaching may play a role in communication between distant groups as the probability of observing this behavior decreased significantly when the nearest whale group was within 4,000 m compared to beyond 4,000 m. Involvement in group interactions, such as the splitting of a group or a group joining with other whales, was an important factor in predicting the occurrence of pectoral, fluke, and peduncle slapping, and we suggest that they play a role in close‐range or within‐group communication. This study highlights the potentially important and diverse roles of surface‐active behaviors in the communication of migrating humpback whales.
One option for the treatment of type 2 superior labral anterior to posterior (SLAP) lesions is arthroscopic repair. However, the fact that the vascular supply of the proximal long head of the biceps ...tendon (LHBT) arises from the soft tissue near the SLAP repair site must also be considered. The aims of this study were to evaluate the vascular channel of the proximal long head biceps tendon and to compare potential damage to the vascular supply with alternative SLAP techniques.
Forty-five fresh cadaveric shoulders were divided into 3 groups: 9 shoulders each for the normal group and the created SLAP group, and 27 shoulders for the repaired SLAP group. SLAP group shoulders were repaired using one of 3 techniques: 2 anchors with simple sutures, 1 anchor with double sutures, or 1 anchor with a horizontal mattress suture. India ink was then injected into the acromial branch of the thoracoacromial artery. The proximal LHBT was resected for a histologic cross-sectional study. The intratendinous vascular distance was measured and compared among the groups.
The vascular supply of the proximal LHBT arises from soft tissue lying anterior and dorsal to the tendon origin. In the normal shoulders, the average intratendinous vascular distance was 16.9 ± 1.5 mm (95% confidence interval: 15.8-18.1). A comparison of nonrepaired SLAPs with each of the repair techniques found that using 2 anchors with simple sutures showed no significant difference in vascular distance (P = .716), whereas the other techniques showed a significant disruption of the blood supply. The differences in vascular distance among the 3 repair techniques were statistically significant (P = .0001).
The main vascular supply of the proximal LHBT comes from the anterior-dorsal direction. Some SLAP repair techniques can disrupt vascularization; however, the technique using 2 anchors with simple sutures, 1 anchor 3 mm anterior to the anterior border and 1 at the posterior border of the tendon, can preserve the vascularization of the LHBT.
The problem faced by the Slap Strap Making Business Group is that the process of making slap ropes is still manual using a hand drill. This business group experienced many problems when using manual ...methods, such as the results of the twisting of the slapping rope were not uniform and many were loose. The second obstacle faced is that manual labor requires a lot of manpower for the slap rope spinning process. The last obstacle faced is when using a spinning machine there is a concern that the electricity supply will not be able to meet because the electricity supply in the area around the coast still uses 450 watts of electricity. So that if you use a spinning machine, it is hoped that the machine can be energy efficient and easy to use. The right solution is offered to solve the problem of the need for a spinning machine that is energy efficient and easy to use, namely the manufacture of a slap rope spinning machine with a chain shaft system. The machine includes various components, among others; frames, shafts, bearings, gears, dimmers, belts and pulleys. The propulsion system uses an electric motor. By using the slap rope spinning machine, it is be able to increase the efficiency and effectiveness of the slap rope spinning process.
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.
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.
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.
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.
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.
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.
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).
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.
