Abstract

Volkmann's ischemic contracture is the end result of an untreated, delayed or Inadequately decompressed compartment syndrome in which muscle ischemia and necrosis have occurred. Once the muscle necrosis have happened, the involved muscle undergo permanent change into fibrous tissue. So secondary shortening and distal joint contracture will be a final outcome, which results in marked functional impairment of hand and forearm. Even though several procedures, such as muscle sliding operation has been attempted, overall results were far from satisfaction, compare to healthy opposite hand. The management of these unfavorable condition of the forearm and hand was regarded as one of challenging area in orthopedics. Recently new approach, using microsurgical technique which transfers functioning muscle unit, has been developed and its result was much better than any other methods in the aspect of an active motion. Among these musculocutaneous free flaps, gracilis has obtained special reputation due to its easiness to handle such as elevation of flap and reliable neurovascular pedicle. Other advantages are flexibility of flap size to adjust variable size of the defect in the forearm and minor morbidity of the donor site. Authors have performed 7 cases of functioning gracilis musulocutaneous free flap transplantation for the functional loss of forearm and hand due to Volkmann's ischemic contracture or muscle and skin defect due to severe trauma since November, 1981 till May, 1991. The results in most cases were satisfactory and acceptable.
