Single tendon transfer of the flexor carpi ulnaris for high radial nerve palsy

Abstract

Complete radial nerve palsy results in a lack of extrinsic extensors of the wrist, fingers and thumb. The optimal treatment of persistent hight radial nerve palsy is tendon transfer, which leads generally to acceptable results with better extension of the fingers and ability to grasp large objects. There are a multiple techniques of tendon transfers from a single to multiple one generally three tendons, however a single flexor carpi ulnaris tendon (FCU) transfer has some advantages, including simplicity, shorter operation time, less morbidity and less surgical scars, which can be important in some patients, particularly women. We present a case report of single tendon transfer of the FCU to the digital extensors for high radial nerve palsy secondary to closed diaphyseal humeral fracture.
