Shoulder resurfacing for treatment of focal defects and diffuse osteoarthritis.

Abstract

This article provides a review of the various options for the treatment of osteoarticular pathology of the shoulder. This can range from focal osteochondral defects to diffuse arthritis and can occur at any age. Although total shoulder arthroplasty and hemiarthroplasty are the most frequently used methods, they not generally suitable for younger patients under 60 years old due to the lack of long-term stability and deterioration. If conservative treatment is unsuccessful or not an option, resurfacing is an alternative procedure with good long-term results. The various methods that have been reported for resurfacing and partial resurfacing of the humeral head are described as well as the results of studies on these procedures. In this article the indications, biomechanics, outcomes and complications are outlined for the two resurfacing options preferred by the authors.
