Carpal tunnel syndrome: the new 'industrial epidemic'.

1. Symptoms of carpal tunnel syndrome (CTS) include numbness, tingling, and decreased sensation in the fingers. 2. The main occupational causes of CTS include repetitive wrist flexion and extension, strong gripping with ulnar deviation, impact forces on the palm, and vibratory forces. 3. Conservative treatment includes a metal-reinforced splint that prevents flexion and extension of the wrist. Surgical treatment may be needed for severe symptoms. 4. Prevention of CTS requires early diagnosis, job reassignment, and tool redesign.
