An 18 yr old male is reported with arthrogryposis involving his arms and hands, apparently caused by congenital hypogenesis of the flexor muscles of the upper arms and forearms, and scapular muscles. His monozygotic twin was unaffected. At birth, he had fixed extension and rotation of arms with flexion contractures of the wrist and fingers. At the time of transplantations of the pectoralis muscles to the ulnas, no flexor muscles were found, but some fibrous bands appeared to have replaced some missing muscles. These changes apparently represent a rare form of arthrogryposis involving the arms. The case is discussed with emphasis on possible etiology.
