Factitious extension contracture of the elbow: case report.

A case report of factitious extension contracture of the elbow due to injection-induced fibrous myopathy of the triceps is presented. Crystalline material was demonstrated in muscle biopsies preserved in absolute alcohol and surgical section of the triceps resulted in correction of the deformity. A review of the literature and differentiation between Weber-Christian systemic panniculitis and factitial panniculitis is discussed.
