| Popis: | The initial descriptions of rotator cuff tear arthropathy date back to 1853, when Professor Adams at the University of Dublin characterized chronic rotator cuff tears leading to localized destructive arthritis1. E.A. Codman detailed a case of rotator cuff-mediated hygroma and advanced shoulder arthritis in his classic 1934 self-published monograph2. Throughout the following years, several authors have described advanced arthritis of the shoulder related to inflammatory disorders of the rotator cuff3. The term c uff tear arthropathy was coined by Charles Neer in 19774. Neer described the pathoanatomical changes associated with chronic full-thickness rotator cuff tears, which include erosions of the osseous structures, humeral osteopenia, and restricted shoulder motion (Fig. 1). Subsequently, the massive tears allow superior displacement of the humerus into the subacromial space resulting in “femoralization” of the humeral head (erosion of the greater tuberosity) and “acetabularization” of the coracoacromial arch (reshaping of the arch so that it creates a socket for the proximal aspect of the humerus)4 (Fig. 2). Fig. 1 The pathological changes associated with a massive rotator cuff tear at the precollapse stage include atrophy of the articular surface, rupture of the long head of the biceps, and superior migration of the humeral head. (Adapted from: Neer CS, Craig EV, Fukuda H. Cuff-tear arthropathy. J Bone Joint Surg Am. 1983;65:1236.) Fig. 2 The progressive pathological changes associated with cuff tear arthropathy include superomedial erosion of the joint, glenohumeral incongruity, and an unstable humeral head. A-C = acromioclavicular. (Adapted from: Neer CS, Craig EV, Fukuda H: Cuff-tear arthropathy. J Bone Joint Surg Am. 1983;65:1237.) The exact etiology of this condition is unknown. The numerous pathomechanical concepts that have been postulated for the development of cuff tear arthropathy are described below. ### Crystal-Mediated Theory An association between rotator cuff tear arthropathy and the presence of … |
