Omarthrose – Pathogenese, Klassifikation, Diagnostik und Therapie

Abstract

Primary osteoarthritis of the shoulder represents adestructive joint disease with associated synovitis, which in the first line seems to be genetically determined. Clinically, patients suffer from shoulder pain with progressive impairment of both active and passive range of motion. The diagnostics include aclinical examination, imaging by native radiography and magnetic resonance imaging (MRI) for assessment of the rotator cuff. Current classification systems consider the formation of humeral osteophytes, glenoid morphology and loss of humeral sphericity. Non-surgical measures include, apart from topical and oral analgesics, injection of corticosteroids and hyaluronic acid supported by physiotherapeutic measures. After failure of non-surgical therapeutic measures, arthroscopic joint-preserving arthroplasty in terms of the comprehensive arthroscopic management (CAM) procedure can be performed in young patients with early stage osteoarthritis, whereas in advanced stages endoprosthetic joint replacement is indicated.
