Cuff Arthropathy Hemiarthroplasty


When a rotator cuff tear is left untreated, the risk of developing a larger, irreparable tear increases. In some cases the tear becomes so massive, the humeral head pushes through the defect and migrates superiorly. Continued neglect leads to altered shoulder motion and articular cartilage contact with the superior edge of the glenoid and the acromion. Over time, this leads to articular cartilage loss and the inability to forward flex the arm, a condition known as Rotator Cuff Arthropathy (RCA). The pathognomonic signs of RCA are a massive, irreparable cuff tear, pseudoparalysis of the arm, and end-stage cartilage loss in the glenohumeral joint. The treatment options for RCA were marginal at best until the development and availability of Reverse Shoulder Arthroplasty.
