Arthroplasty and Rotator Cuff Deficiency

摘要: Rotator cuff deficient shoulders with degenerative joint disease are a treatment challenge. Most patients present primarily due to shoulder pain. Shoulder function can be variable even significant chronic rotator deficiency. The arthritic condition of the tear has been termed cuff-tear arthropathy [1]. This is characterized clinically by pain and poor active motion, but near normal passive motion. Within there crepitus occasional fluid production seen under deltoid. On manual muscle testing, weakness elevation external rotation. Radiographically, this humeral head. There loss space at glenohumeral adaptive changes on acromion heads. Typically new acromiohumeral articulation formed (Figure 7.1). In advanced conditions, collapse head incongruity between superior glenoid, undersurface acromion. pattern more wear concavity 7.2). centralized glenoid bone stock 7.3). also massive destructive head, 7.4A 7.4B).

To make matters confusing, not every an irreparable goes painful, symptomatic arthropathy.
