title: Carpal tunnel syndrome: modern diagnostic and management techniques.
abstract: Carpal tunnel syndrome is a common disorder characterised by the classical symptoms of numbness and paraesthesiae along the distribution of the median nerve. Thenar muscle weakness is a late manifestation of advanced disease. Tinel's and Phalen's signs are helpful in suggesting the diagnosis. The symptoms and signs arise from entrapment of the median nerve. Electrophysiological tests are helpful in confirming the diagnosis and magnetic resonance imaging may be used in the diagnosis of atypical cases. Ergonomic manoeuvers and steroid injections may alleviate symptoms in mild cases. Surgery is reserved for severe cases and those who do not respond to conservative therapy. Open carpal tunnel release is the classical surgery with usually excellent results. Endoscopic carpal tunnel release surgery was introduced to decrease the morbidity of open surgery. This latter technique also has its complications and is still being refined.
