Can the outcome of carpal tunnel release be predicted?

Between 1994 and 1996 we performed a prospective study on the effect of carpal tunnel release on the health status of 96 patients. The Nottingham Health Profile, a validated global scoring system, was used to assess quality of life before, and at 4 months after surgery. Carpal tunnel syndrome had a significant impact on the health status of our patients. There were significant improvements in the scores for pain, energy and sleep. Patients who were dissatisfied following surgery had significantly higher pre-operative scores, indicating poor perceived health status. Our findings show that outcome assessment tools have predictive value in identifying patients who may not benefit from surgery, or in whom a poor result might be anticipated.
