Osteochondritis dissecans of the humeral head.

Abstract

A rare case of osteochondritis dissecans (OCD) occurring in the humeral head is presented. As there are only six available records in the literature concerning OCD in the humeral head, clinical features, treatment, and etiology of OCD involvement of this anatomical part remains unclear. These points are discussed on the basis of the previous cases and ours. Osteochondritis dissecans of the humeral head commonly affects middle-aged and young males rather than females. The prevalent location of involvement is the anterosuperior aspect of the humeral head. We propose that repetitive microtrauma is one of the important causes of OCD in the humeral head. Moreover, we suggest that the most authentic treatment for OCD with a partial detached osteochondral fragment is removal of this fragment and drilling.
