Upper extremity surgery in stroke patients.

Abstract

Surgical procedures are performed on the nonfunctional upper extremity following stroke to correct spastic flexion contractures that cause pain or prevent adequate hygiene. In the upper extremity surgical procedures are most commonly performed to improve extension at the wrist, fingers or thumb. If the deformity is primarily due to spasticity rather than fixed myostatic contracture, anesthetic block of the median and/or ulnar nerve preoperatively enables the surgeon to determine that extension will be improved after the appropriate flexor tendons are lengthened. Careful presurgical evaluation of motor sensory function enables the surgeon to predictably select those patients who will benefit from surgery.
