When the nerves or tendons inside the carpal tunnel swell or become inflamed (carpal tunnel syndrome), pressure on the nerve causes pain, numbness, tingling, or weakness in the fingers and wrist.
The nerve most commonly affected in carpal tunnel syndrome is the median nerve, which provides motor and sensory function to the hand.
Most physicians recommend trying non-surgical treatments (such as: splinting the wrist, using anti-inflammation medications) before recommending surgery.
Carpal tunnel repair is done while the patient is awake or sleepy and pain-free (local or regional anesthesia) or deep asleep and pain-free (general anesthesia). Through an incision on the inside of the wrist, the carpal ligament is cut open to relieve the pressure on the nerve. The incision is stitched (sutured) closed.
