As for remote sequelae of traumatic lesions of the brachial plexus, one of the most urgent problems of their treatment is restoring a function of an upper extremity.
We performed transposition of the following muscles: the broadest muscle of the back (BMB) - 21 cases, musculus pectoralis major (MPM) - 5 cases, the triceps - 4 cases. They were transposed on an anterior surface of a shoulder for restoration of active flexion of a forearm. Tendons of radial and ulnar flexors of a hand were transposed on a forearmís straightening surface with fixing the radial flexor tendon to the extensor tendons of the 2nd-5th fingers and the ulnar flexor tendon to a tendon of the long extensor of the thumb (7 cases); it was done with the purpose of restoring extension of a hand and fingers. It allowed to obtain excellent and good results.
If impaired flexion of a forehand and impaired extension of a hand, fingers were associated, we used a combined double-stage method of muscle and tendon transposition. The first stage consisted in transposition of MPM (3 cases), BMB (2 cases) on a forearmís anterior surface for ensuring its active flexion in an elbow joint. After restoration of a volume and strength of active flexion we performed tendon-muscle transposition for restoring extension of a hand and fingers. We got excellent (4 cases) and good (1 case) results. Active flexion of a forearm and extension of a hand and fingers were restored.
A combined method of muscle and tendon-muscle transposition, used in remote sequelae of traumatic lesions of the brachial plexus, is an effective means of restoring an upper extremity function in proximal and distal segments.
