We can diagnose any lesion in the following:
1-Tendons: As for subscapularis, infra spinatus and biceps in the groove.
2-Ligaments: As middle glenohumeral ligament.
3-Bones: Hill-Sack's injury which is a groove occur in the head of the humerus posteriorly due to anterior dislocation of the humeral head.
|
- Bankart lesion (humeral head driven forward –> anterior labral detachment, capsule tear)
- Hill-Sachs lesion (compression fracture at posterolateral margin of humeral head)
- Possible associated fracture of proximal humerus, anterior glenoid and disruption of glenohumeral ligaments
|
4-Labrum: Anterior and posterior.
5-Bursa: Such as subscapularis and subcoracoid.
|
Subsubscapularis bursitis |
|
Subcoracoid bursitis |
