    Arthroscopic-Assisted Latissimus Dorsi Tendon Transfer for Massive, Irreparable Rotator Cuff Tears: Technique and Short-Term Follow-Up of Patients With Pseudoparalysis
    (W B Saunders Co-Elsevier Inc, 2017) Kanatli, Ulunay; Ozer, Mustafa; Ataoglu, Muhammet Baybars; Ozturk, Burak Yagmur; Gul, Orkun; Cetinkaya, Mehmet; Ayanoglu, Tacettin
    Purpose: To describe a modified technique for arthroscopic-assisted transfer of the latissimus dorsi tendon in a selected group of patients with irreparable rotator cuff tears and pseudoparalysis and to evaluate its short-term results. Methods: Fifteen patients with irreparable rotator cuff tears and pseudoparalysis treated by arthroscopic-assisted latissimus dorsi tendon transfer were included. The mean patient age was 61.53 +/- 6.24 years (range, 52-71 years). Patients were assessed with physical examination, University of California Los Angeles (UCLA) Score and Constant-Murley score, as well as visual analog scale score at a mean follow-up of 26.4 +/- 2.58 months (range, 24-31 months). Results: At final follow-up, mean UCLA score increased to 27.47 +/- 6.31 compared with the preoperative UCLA score of 6.53 +/- 2.1 (P < .001). Constant-Murley score was 21 +/- 7.41 and 59.73 +/- 13.62 (P < .001), visual analog scale pain score was 7.47 +/- 1.06 and 2.47 +/- 0.91 (P < .001), active forward flexion was 58 degrees +/- 21.11 degrees and 130 degrees +/- 30.05 degrees (P < .001), active abduction was 51 degrees +/- 1.64 degrees and 129.67 degrees +/- 25.45 degrees (P <.001), and active external rotation was 13.33 degrees +/- 21.68 degrees and 32 degrees +/- 18.03 degrees (P < .001) preoperatively and postoperatively, respectively. Mean acromiohumeral distance was 3.13 +/- 1.40 mm preoperatively, whereas it was 5.67 +/- 1.67 mm postoperatively (P < .001). No significant complications requiring a revision surgery was observed during the final follow-up. Conclusions: The modified technique of arthroscopic-assisted transfer of the latissimus dorsi tendon is a feasible, minimally invasive option for the surgical treatment of irreparable rotator cuff tears in a subset of patients with pseudoparalysis.

    The middle glenohumeral ligament: a classification based on arthroscopic evaluation
    (Mosby-Elsevier, 2022) Kaptan, Ahmet Yigit; Ozer, Mustafa; Alim, Ece; Percin, Ali; Ayanoglu, Tacettin; Ozturk, Burak Yagmur; Kanatli, Ulunay
    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. (C) 2021 Journal of Shoulder and Elbow Surgery Board of Trustees. All rights reserved.

    Multiple Subscapularis Tendon Sign A New Risk Factor for Recurrence After Arthroscopic Anterior Shoulder Instability Surgery
    (Sage Publications Inc, 2019) Kanatli, Ulunay; Ozer, Mustafa; Gem, Mehmet; Ozturk, Burak Yagmur; Ataoglu, Muhammet Baybars; Cetinkaya, Mehmet; Ayanoglu, Tacettin
    Background: Being able to predict recurrence after the treatment of shoulder instability would be helpful in planning the appropriate treatment. Purpose: To define the multiple subscapularis tendon sign (MSTS) as a novel anatomic variant and a possible risk factor for the recurrence of shoulder instability after anterior stabilization and to evaluate it, together with the other risk factors as described in the literature. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 87 patients met the study criteria and underwent arthroscopic stabilization for anterior shoulder instability. The MSTS was evaluated in this study group. Age, sex, hand dominance, number of preoperative shoulder dislocations, history of overhead or contact sports participation, type of labral lesion, number of anchors used in surgery, presence of the drive-through sign, presence of the MSTS, Oxford Shoulder Score results, and the association of these parameters with recurrence were assessed. The mean follow-up time was 81.0 +/- 27.9 months (range, 48-139 months). Results: Nine (10.3%) patients experienced recurrent instability. The presence of the MSTS (P = .009), existence of an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion (P = .04), and history of overhead or contact sports participation (P = .04) were significant risk factors for recurrence. The recurrence rates were as follows: 30.7% with the MSTS; 40% with the MSTS and an ALPSA lesion; and 75% with the MSTS, an ALPSA lesion, and a history of overhead or contact sports participation. Conclusion: The MSTS is a variation of the anterior shoulder joint capsule. It is a sign of capsular insufficiency or thinning, which may be a risk factor for recurrence after anterior stabilization. Considering the low success rates of anterior capsulolabral repair in patients participating in overhead or contact sports, especially when an ALPSA lesion is present, encountering the MSTS during surgery in this at-risk group may be an indicator for the surgeon to choose the surgical procedure more carefully.
