TENDON TRANSFER TO RECONSTRUCT WRIST EXTENSION IN CHILDREN WITH OBSTETRIC BRACHIAL PLEXUS PALSY

Abstract

This study reports on 20 children with obstetric brachial plexus palsy who underwent a tendon transfer to reconstruct wrist extension. The mean age at the time of tendon transfer was 8 years. There were seven patients with Erb's palsy and the remaining 13 had total palsy. The flexor carpi ulnaris was utilized 15 times and the flexor carpi radialis five times. The transferred tendon was sutured to the tendon of the extensor carpi radialis brevis. The result of the transfer was assessed according to a modified Medical Research Council (MRC) muscle grading system. A good result was obtained in 18 patients (modified MRC grade of 4) and a fair result (modified MRC grade of 3) in two. The choice of tendon transfer to reconstruct the wrist drop deformity in various conditions including adult traumatic brachial plexus injuries is discussed.
