“…Labral degeneration may be difficult to differentiate from the numerous labral variants as described before (15).The frequency of posterior labrocapsular complex lesion after acute posterior shoulder dislocation was 58% in a previously published study (16). However, only occasional labral tears were observed in other reports in patients with acute posterior shoulder dislocation (17,18), indicating possible problems with the differentiation of degeneration or variants from symptomatic tears. The 3D true FISP sequence provides a T2-weighted component and thus demonstrates bursitis and bone marrow edema-like abnormalities.…”

“…It showed that when posterior shoulder dislocation occurred, the teres minor injury should be considered and vice versa. Hottya et al, 3) who reported four cases of teres minor muscle injury after posterior shoulder dislocation injury, described two of four patients with a teres minor tear at its tendinous portion without other rotator cuff tendon tear. They could not suggest the exact reason for correlation between posterior shoulder dislocation and teres minor muscle, they assumed that inseperation between the underbelly of the teres minor muscle and the posterior capsule of the glenohumeral joint 5) might explain associated injuries to teres minor during posterior capsular damage.…”

“…Isolated teres minor tendon tear is a rare disease entity. Hottya et al 3) reported two cases with isolated teres minor tear at its tendinous portion but they did not describe their treatment and outcomes. There are no reports on treatment and outcomes of an isolated teres minor tear, therefore, the purpose of the current case study is to report on arthroscopic treatment and its outcome of the isolated teres minor tear and to review the literature.…”

Arthroscopic repair of an isolated teres minor tendon tear without associated shoulder joint pathology has not been reported in the literature. We report on a case of isolated teres minor tendon tear after trauma. The patient complained of severe shoulder pain and progressive limited range of motion 4 months after the injury. Magnetic resonance imaging showed a full-thickness tear of the teres minor tendon at its musculotendinous junction and arthroscopic repair was performed. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. Here, the authors report this case and provide a review of literature.

“…A posterolateral portal just off the posterolateral margin of the acromion was established for initial viewing, along with a standard anterosuperior portal in the rotator interval, and a port-of-Wilmington posterosuperior portal. 10 Clear cannulas, 5.75 mm in diameter (Arthrex, Naples, FL), were placed in the rotator interval and the port of Wilmington. A larger 8.25-mm clear cannula (Arthrex) was placed posterolaterally.…”

“…5,[7][8][9] Teres minor avulsions are rare and, when present, frequently occur in combination with supraspinatus, infraspinatus, or massive rotator cuff tears. [10][11][12] To our knowledge, there is no mention in the literature of a bony posterior HAGL lesion that also involves an isolated teres minor tendon avulsion. We describe the arthroscopic treatment of a traumatic posterior HAGL variant with a bony avulsion and a lesion involving the teres minor tendon.…”

Humeral avulsion of the inferior glenohumeral ligament (HAGL) has recently gained more recognition as a cause of shoulder instability. Posterior HAGL lesions, being much more infrequent than anterior disruptions, have only recently been documented as a notable cause of posterior instability. We detail the treatment of a previously unreported case of a posterior HAGL variant lesion consisting of a bony avulsion with involvement of the teres minor tendon. Arthroscopic fixation was facilitated by use of a "sheathless" arthroscopic approach with a 70 arthroscope and suture anchor.G lenohumeral instability can result from a wide range of factors. Increased recognition has been given to the humeral avulsion of the inferior glenohumeral ligament (HAGL) lesion. The typical HAGL lesion most commonly described is an avulsion of the anterior inferior glenohumeral ligament from its attachment on the humerus. 1,2 This leads to anterior instability, which occurs much more frequently than posterior instability. 3,4 The posterior HAGL lesion, however, has been described as a cause of posterior shoulder instability or pain. 5,6 Diagnosis can be difficult and is often delayed because of nonspecific shoulder pain or multiple potential etiologies for isolated posterior shoulder pain. These may include tears of the labrum, capsule, or rotator cuff or bony insufficiency. Posterior HAGL lesions have been documented in association with anterior and posterior Bankart lesions; anterior, superior, and posterior labral lesions; and anterior labral periosteal sleeve avulsion lesions. Both open repair and arthroscopic repair have subsequently been described. 5,7-9 Teres minor avulsions are rare and, when present, frequently occur in combination with supraspinatus, infraspinatus, or massive rotator cuff tears. [10][11][12] To our knowledge, there is no mention in the literature of a bony posterior HAGL lesion that also involves an isolated teres minor tendon avulsion. We describe the arthroscopic treatment of a traumatic posterior HAGL variant with a bony avulsion and a lesion involving the teres minor tendon. CaseA 16-year-old right handedominant male baseball player sustained a traumatic injury to his left shoulder when he ran into an outfield fence chasing a fly ball. He forcefully struck the wall with a direct blow to the anterior and lateral aspects of the shoulder. He described the sensation of a "slip" of his shoulder but did not sustain a frank dislocation. Radiographs obtained the day of injury yielded negative findings. His examination showed good active motion with minimal rotator cuff weakness. Conservative management for a shoulder strain was subsequently initiated.After 4 weeks of physical therapy, the patient still had persistent shoulder pain, localized anteriorly, with no symptomatic improvement. His physical examination at that time showed diffuse anterior tenderness to palpation. He had full active range of motion with The authors report the following potential conflict of interest or source of funding: P.A.S. rec...
