The histopathology of the humeral head in glenohumeral osteoarthritis.

ABSTRACT:

Objective

The histopathologic wear patterns in glenohumeral osteoarthritis (GOA) have not been described. The aims of the study were to a) describe the histopathology of humeral head wear patterns in patients with end-stage GOA and b) identify clinical and radiographic parameters that correlate with observed histopathological wear patterns.

Methods

Eighteen humeral heads from patients undergoing anatomic total shoulder arthroplasty for end-stage osteoarthritis were divided radially into eight wedge-shaped zones. Each zone was subdivided into central and peripheral regions. Histologic analysis included measurements of cartilage and subchondral bone plate thickness, subchondral bone area, and cartilage structure was scored using the Osteoarthritis Research Society (OARSI) and
