Hello, I just read your query and would like to say that these three things are enitirely diffferent entities and change the management approach although they are extremely closely related. Anterior labral tear -The dislocation of the humeral head to antero-inferior causes damage to the antero-inferior rim of the glenoid in the 3 - 6 o clock position. It occurs particularly in younger patients and this results in a Bankart fracture or a Bankart lesion which is a tear of the anteroinferior labrum. This results in instability and recurrent dislocations. Hill Sach s deformity-Hill-Sachs is a posterolateral depression of the humeral head. It is above or at the level of the coracoid in the first 18 mm of the proximal humeral head. It is seen in 75-100% of patients with anterior instability. Due to these recurrent dislocations significant bone loss and erosion of the anterior glenoid rim may occur, which maintains the unstable situation. Partial thickness rotator cuff tear -The classical description of the rotator cuff involves a convergence of 4 tendons(the end part of muscles of shoulder): supraspinatus, infraspinatus, teres minor, and subscapularis. These tendons form a multiple layered horseshoe shape flattened architecture which inserts onto the humeral head .So there was a tear here. So it seems that every time your shoulder caused a new injury . Hope that helps solve your query.Goodluck
