Forearm contracture, especially pronation contracture, has been noted after fractures of the forearm, inflammation, osteoarthritis of the wrist and elbow, and spastic paralysis. Although various procedures, such as the Steindler method, Tubby-Denisch method, and osteotomy of the forearm, are recommended for these contractures, progress is not simple but complicated. We report a case of release of the pronator teres muscle and excision of the proximal interosseous membrane for contracture of the forearm due to burn.
A 28 year-old male sustained burns over 60% of his body in a traffic accident at 22. Skin graft was performed for his body over ten times, and his right upper limb was amputed. He indicated severe loss of supination after the skin grafts, neurolysis of the median nerve, and opponens plasty. Release of the pronator teres muscle and excision of the proximal interosseous membrane were performed. The operation increased supination from 20 degrees to 80 degrees. He maintained good range of motion after the operation and returned to his previous job.
