rotator cuff tear Arthropathy
Journal of The American Academy of Orthopaedic Surgeons, 2007Co-Authors: Kier J Ecklund, James E Tibone, Ranjan GuptaAbstract:: Rotator cuff tear Arthropathy represents a spectrum of shoulder pathology characterized by rotator cuff insufficiency, diminished acromiohumeral distance with impingement syndromes, and arthritic changes of the glenohumeral joint. Additional features may include subdeltoid effusion, humeral head erosion, and acetabularization of the acromion. Although the progression of rotator cuff tears seems to play a role in the development of cuff tear Arthropathy, information is lacking regarding the natural progression of rotator cuff tears to cuff tear Arthropathy. Controversy remains about the role of basic calcium phosphate crystals in the development of cuff tear Arthropathy. Nonsurgical management is the first line of treatment in most patients. Traditionally, surgical management of rotator cuff tear Arthropathy has been disappointing because of the development of complications long-term and poor patient satisfaction with functional outcomes. Recent studies, however, report promising experience with reverse ball-and-socket arthroplasty.

rotator cuff tear Arthropathy evaluation diagnosis and treatment aaos exhibit selection
Journal of Bone and Joint Surgery American Volume, 2012Co-Authors: Travis G Maak, Bradley S Raphael, Christopher K Kepler, Michael B Cross, Russell F WarrenAbstract:Abstract: Rotator cuff tear Arthropathy encompasses a broad spectrum of pathology, but it involves at least three critical features: rotator cuff insufficiency, degenerative changes of the glenohumeral joint, and superior migration of the humeral head. Although many patients possess altered biomechanics of the glenohumeral joint secondary to rotator cuff pathology, not all patients develop rotator cuff tear Arthropathy, and thus the exact etiology of rotator cuff tear Arthropathy remains unclear. The objectives of this manuscript are to (1) review the biomechanical properties of the rotator cuff and the glenohumeral joint, (2) discuss the proposed causes of rotator cuff tear Arthropathy, (3) provide a brief review of the historically used surgical options to treat rotator cuff tear Arthropathy, and (4) present a treatment algorithm for rotator cuff tear Arthropathy based on a patient’s clinical presentation, functional goals, and anatomic integrity.

hemophilic Arthropathy of the elbow treated by total elbow replacement
Journal of Bone and Joint Surgery American Volume, 2004Co-Authors: Srinath Kamineni, Robert A Adams, Shawn W Odriscoll, Bernhard F MorreyAbstract:Hemophilic Arthropathy most commonly affects the knee, with the elbow being the second most frequently involved joint1. The recurrent intra-articular hemorrhages that cause this form of inflammatory Arthropathy are a feature of severe hemophilia in which <1% of the normal clotting factor titers are present. Whereas total joint replacement is a well-documented treatment for hemophilic hip and knee Arthropathy2-5, there are very few reports of total elbow replacements in patients with hemophilia. Possible reasons for this lack of published data include (1) the predominant and successful medical management of most patients with hemophilia, (2) less functional impairment of the elbow compared with the hip and knee in hemophilic Arthropathy, and (3) the more recent successful evolution of total elbow arthroplasty compared with the more established hip and knee arthroplasties. Our aim is to share our experience with total elbow arthroplasty in patients with hemophilic Arthropathy and to review the cases reported in the literature. We retrospectively reviewed the records on 3100 patients with hemophilia who had presented to our institution and on 1358 total elbow replacements performed at our institution between 1979 and 2001. Five patients had had total elbow replacement for the treatment of hemophilic Arthropathy (Table I), and we further analyzed those cases. View this table: TABLE I Data on Five Patients with Hemophilia and a Total Elbow Arthroplasty The mean age of the five patients was thirty-nine years (range, twenty-five to fifty-eight years). The elbow on the dominant side was involved in one patient, the elbow on the nondominant side was involved in one patient, and both elbows were involved in three patients. The primary hematological abnormality was hemophilia A (factor-VIII deficiency) in two patients and hemophilia A and B (factor-VIII and IX deficiency), hemophilia C (von Willebrand disease), and hemophilia A with factor-VIII inhibitor in …

cuff tear Arthropathy pathogenesis classification and algorithm for treatment
Journal of Bone and Joint Surgery American Volume, 2004Co-Authors: Jeffrey L Visotsky, Carl J Basamania, Ludwig Seebauer, Charles A Rockwood, Kirk L JensenAbstract: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 …
