The unusual osteochondroma: A case of snapping scapula syndrome and review of the literature.

Snapping scapula syndrome is a rare condition characterized by crepitus of the scapula on motion of the ipsilateral upper extremity. It may be quite painful and disabling. The majority of cases are due to bursal and muscular disorders. Snapping scapula syndrome secondary to an underlying osteochondroma is an even more infrequent phenomenon. The case presented highlights the unusual post pubertal growth of an osteochondroma of the scapula that progressed to develop a snapping scapular syndrome. Review of the literature revealed less than fifty reported cases of this phenomenon secondary to an underlying osteochondroma.
