Rotator cuff arthropathy
Rotator cuff arthropathy is a spectrum of degenerative disease that develops due in a rotator cuff deficient shoulder joint. The term encompasses both rotator cuff tendinopathic change as well as associated joint generative change.
Women are effected more than men and it affects the dominant shoulder more than the non-dominant side 1.
Most patients have shoulder pain, effusions and reduction range of motion. Weakness is usually that seen in cuff tears.
high riding humerus
- superior migration of the humeral head with decreased acromiohumeral distance
- pseudoarticulation of the humerus with the unndersurface of the acromion causing concave acromial erosions and increased sclerosis: acetabularisation of the acromion 1
- this can lead to impingement
- decreased joint space in the superior aspect of the glenohumeral joint and associated osteoarthritic changes (compared with primary OA where the wear is inferomedial on the humeral head and posterior along the glenoid) 1
- rounding of the greater tuberosity
- osteopenia of the proximal humerus and acromion
Treatment and prognosis
Conservative managment icludes NSAIDs and rehabilitation. Surgical management includes joint fusion or replacement with hemiarthroplasty and reverse total shoulder arthroplasty having good results depending on the severity of disease.
