Thirty-eight patients with cerebral palsy had tendon transfers to improve extension of the wrist and fingers. The 10 patients who had poor hand placement, sensibility, or motor control failed to improve in functional grasp or release. The remaining 28 patients, with better preoperative criteria, had improved function. On long-term follow-up, 5 of the 12 patients with transfers to the wrist extensor had extension contractures with difficulty in release, and in seventeen patients transfers to the finger extensors resulted in improved finger extension and release, with no sacrifice in the ability to grasp.
