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;

                - avulsion of inferior ligament from the humerus;
