摘要: Carpal tunnel syndrome involves classic symptoms of numbness and paresthesias in the radial 3-1/2 digits, most frequently nocturnal, pain associated with this distribution. Thenar weakness autonomic dysfunction rarely are seen except advanced cases. Provocative tests on physical examination such as wrist flexion test local percussion sensitivity over median nerve can be extremely helpful determining confirming diagnosis. Nerve conduction velocity electromyographic studies its compression especially difficult cases involving a complex differential It has been clearly documented that negative NCV/EMG study by itself, does not exclude possibility carpal syndrome. The hallmark diagnosis remains history careful examination. Treatment initially consisting splint immobilization steroid injection into canal provide initial relief elimination long-term basis several patient groups. Patients without any resolution after two to three months conservative treatment or those greater than one year's duration generally considered candidates for surgical decompression canal. likelihood operative being required is heightened if involved daily manual repetitive activities hand and/or wrist.
