Bankart Lesion


- Discussion:
- is an avulsion of the anteroinferior glenoid labrum at its attachment to IGHL complex;
- lesion is felt to result from anterior shoulder dislocation and is felt to be primary lesion in recurrent anterior instability;
- when Bankart lesion occurs, there is obligitory concomitant capsular disruption, w/ stretching or elongation of the IGHL;
- in up to 30% of patients the IGHL will heal in a redundant position;
- diff dx:
- glenoid labrum has many variations;
- fraying is the most common and often does not indicate pathology;
- anterior glenoid defect:
- in the experimental study by Itoi I, et al. (2000), the authors studied the role of an anterior gleoid defect (after Bankhart repair) on anterior instability;
- they found that an osseous defect with a width that is at least 21% (about 7 mm) of the glenoid length may cause instability and limit the range of motion of the shoulder after Bankart repair;
- antero-superior labral anomalies:
- congential anomalies of labrum are often seen in its anterior and superior portion;
- isolated lesions of the anterosuperior portion of the labrum which do not involve the biceps brachii, will not cause significant changes in anteroposterior or superoinferior glenohumeral translation;
- surgical debridment is not indicated;
- labral lesions which extend from the anterosuperior portion of the labrum to the biceps insertion will result in significant changes in glenohumeral translation;
- Hagl Lesion:
- avulsion of inferior ligament from the humerus;
