Carpal Tunnel Release: One Port Technique

Abstract

Carpal tunnel syndrome (CTS) results from compression of the median nerve at the wrist. Intermittent compression of the nerve results in numbness and paresthesias in the affected fingers with symptoms being more common at night than during the day. Prolonged or severe compression results in constant numbness and gradual atrophy of the thenar musculature with associated loss of thumb dexterity. The diagnosis of CTS is often made from history alone, but can be confirmed by careful physical examination including the positive wrist flexion test (Phalen’s sign) and the positive median nerve percussion test (Tinel’s sign), presence of thenar atrophy, altered sensation (vibration, two-point discrimination), and ruling out median nerve compression at other sites that might lead to “double-crush” syndrome.1 Frequently electrodiagnostic studies are ordered although many feel that clinical history and examination are adequate to make the diagnosis.2 The electrodiagnostic studies are particularly useful in individuals who present an atypical symptom complex.
