Classification and treatment of postburn proximal interphalangeal joint flexion contractures in children.

Two hundred and sixty-four surgically treated proximal interphalangeal joint flexion contractures in children were reviewed. A classification system on the basis of contracture severity was devised to assess the efficacy of treatment. Contracture severity was determined from preoperative radiographs and physical examination. Eighty-eight percent of the digits were successfully treated (postoperative contracture less than 20 degrees). Unsatisfactory results (12% of digits) were directly proportional to the severity of the contracture and tended to occur in older children with large total body surface burns. The time interval between burn and contracture release did not correlate with contracture severity or therapeutic failure. The most common cause of an unsatisfactory result was failure to fully release the contracture.
