Carpal tunnel release is a highly effective treatment for Carpal Tunnel Syndrome. Clinicians considering referral for surgical management should be aware that good surgical outcome is best correlated with a combination of positive clinical and positive electrodiagnostic studies (EDX). Clinical tests together with EDX have a better association with surgical outcome than either alone. Pre-op nerve conduction study severity can also better predict time to resolution and degree of resolution of symptoms.
