Carpal Tunnel Syndrome: Sensitivity and Specificity

Introduction: Actual median nerve neuropathy. See also Forearm Flexor Tenosynovitis - most physical exam findings for Carpal Tunnel Syndrome actually pick up Tenosynovitis in the carpal tunnel (i.e. from flexor tendonitis) far better than they do 'Carpal Tunnel' (i.e. median neuropathy). Tendonitis should be managed medically, while neuropathy would be treated by surgical decompression.
