There is no specific clinical test that may differentiate a HAGL from a standard Bankart lesion
(14), however, in the case of anterior instability, a history of repetitive microtrauma with generalized ligamentous laxity during the physical exam is thought to be a common presentation with the hallmark abnormality believed to be inferior capsular laxity with or without associated lesions of the labrum-ligament complex (17-19).
Identification of Lesion: A diagnostic arthroscopy was performed, and the presence of the Bankart lesion
(An anterior inferior avulsion of the capsulolabral complex of the glenoid was confirmed.
In this study, we evaluated the mid-term results of minimally invasive modified Latarjet technique in traumatic anterior recurrent dislocations associated with gross Hill-Sachs and Bankart lesions
FIGURE 2A: Axial T2W 3D FFE image shows tear of anteroinferior labrum (white circle): Soft tissue Bankart lesion
However, in a position of ER the anterior soft tissue structures became taught, shifting edema posterior in the capsule, thereby permitting coaptation of the Bankart lesion
to the glenoid.
In a review of the literature, unaddressed capsular laxity and Bankart lesions
(12) have been cited as the most common pathologies associated with continued instability after surgical stabilization procedures (Table 2).
The proposed mechanism of injury is a hyperabduction and external rotation force versus a hyperabduction and impaction force which would result in a Bankart lesion
Comparison of open and arthroscopic stabilization for recurrent shoulder dislocation in patients with a Bankart lesion
Hecker AT, Shea M, Hayhurst JO, Myers ER, Meeks LW, Hayes WC: Pull-out strength of suture anchors for rotator cuff and Bankart lesion
The anatomic repairs tend to address the detachment of the anterior inferior glenohumeral ligament from the anterior inferior labrum, the classical Bankart lesion
They found that both are effective stabilizers in abduction and external rotation, especially with a Bankart lesion
18) After creating a simulated Bankart lesion
and applying an anterior force to the humerus, Itoi and colleagues (31) demonstrated in cadaveric studies that the anterior displacement with the biceps loaded was significantly less than with any of the rotator cuff muscles loaded.
