Flexor Carpi Ulnaris Tendon Transfers in Cerebral Palsy

Abstract

Flexor carpi ulnaris tendon transfer to either the extensor carpi radialis longus or extensor carpi radialis brevis has become a standard procedure to improve function in patients with cerebral palsy. In this retrospective study of the procedure, we have compared preoperative and postoperative wrist position, analysed potential outcome predictors and assessed function by objective and subjective measures. Sixteen children, with flexor carpi ulnaris transfer to extensor carpi radialis longus or brevis or extensor digitorum, were tested at an average follow-up of 4 years (range, 1–9). General resting position improved and the centre of the arc of motion averaged 6° pronation and 9° extension. Subjectively, 14 of 16 parents felt there was an improvement in function, 16 of 16 felt that cosmesis was improved, 14 of 16 would recommend the procedure to others, and 15 of 16 were satisfied overall.
