Carpal tunnel syndrome (CTS) is a median nerve mononeuropathy caused by entrapment within the carpal tunnel. Patients often present with paresthesias and dysesthesias initially, progressing to weakness and functional loss if left untreated. On examination, sensory loss and positive provocative tests such as Phalen’s and Tinel’s are common. Severe cases demonstrate atrophy of the muscles innervated by the median nerve distal to the wrist. While diagnosis is largely clinical, electrodiagnostic studies are used to confirm the diagnosis as well determine severity, which is especially important prior to surgery. Conservative management includes rest, therapy, splinting, and use of either oral or injected corticosteroids. However, in advanced disease or cases failing conservative treatment, surgical intervention is necessary.
