“…7). This may occur as of the first episode of instability [19], and in 72% of cases is associated with bone lesion of the anterior edge of the glenoid cavity and in 90% with a humeral notch [19,20]. It is caused by detachment of the MGHL and IGHL from the glenoid [17].…”

The glenoid labrum is the fibrocartilage of the shoulder joint, anchoring the joint capsule and shoulder ligaments. Morphology varies regionally, especially in the superior and anterior region; these variants can sometimes be confused with pathological aspects. The labrum is often involved in shoulder pathology, by single trauma or, more often, repeated microtrauma. It seems logical to classify and to describe tears according to two criteria: the sector involved, and associated pain or instability. In the superior labrum, SLAP lesions are the most frequent. These combine labral lesion and lesion of the proximal insertion of the long head of the biceps brachii tendon. The most frequent form is SLAP II. They may be associated with instability or not. In the antero-inferior and postero-inferior labrum, lesions are mainly due to instability, particularly Bankart lesions (capsulolabral avulsion) anteriorly and Kim's lesion posteriorly. Circumferential labral lesions may be found in unstable shoulder. Finally, postero-superior lesions involve Walch's internal impingement: repeated contact between the deep surface of the cuff and the labrum, which takes on a degenerative aspect, with a kissing lesion of the cuff. There is no general rule for management: some labral lesions are resected and others fixed. The cause (which is usually shoulder instability), however, needs to be assessed and treated.

“…Anterior glenoid bone defects are frequently associated with shoulder instability and are considered one of the major causes of recurrence of instability after shoulder stabilization [ 22 ]. The glenohumeral joint is inherently predisposed to instability by its bony architecture, especially with the mismatch between the sizes of the humeral head and glenoid.…”

“…The lesion signifi cantly predisposes the patient to recurrent instability [ 21 ]. Presence of a defect was signifi cantly associated with recurrence of dislocation compared with a single episode of dislocation in a study by Milano et al [ 22 ]. It can be diffi cult to accurately defi ne the size of the fracture fragment as a percentage of the glenoid.…”

“…Advances in imaging (magnetic resonance imaging and computed tomography) and enhanced arthroscopic visualization of the shoulder have enabled us to better define and address the pathology of instability. 2,3 We can now tailor our surgical approach to the amount of anterior bone loss, the degree of capsulolabral laxity, and the size of the Hill-Sachs lesion.…”

Abstract:The arthroscopic treatment of the "bony Bankart lesion" continues to evolve. We present a novel technique that we developed at Orthopaedic Research of Virginia, the "transosseous bony Bankart repair," which incorporates several essential concepts to provide for optimal healing and rehabilitation. We promote arthroscopic repair emphasizing bone preservation, a fracture interface without interposing sutures, the ability to reduce capsular volume, and multiple points of stable glenolabral fixation. Our technique positions suture anchors within the subchondral bone of the intact glenoid to allow for an anatomic reduction of the bony fragment. By use of an arthroscopic drill, spinal needle, and nitinol suture passing wire, the sutures are passed in a retrograde fashion through the bony Bankart fragment and anterior capsule in a mattress configuration. Additional inferior and superior anchors are placed to further provide stability and reduce capsular volume. While maximizing fracture surface area and optimizing bony healing, the end result is an anatomic reduction of the bony fragment and the glenoid articular surface.
