Carpal tunnel syndrome is a condition that affects the hand and wrist. This condition occurs when there is pressure on the median nerve caused by swelling in the carpal tunnel. Swelling can be caused by a range of factors including illnesses (hypothyroidism, rheumatoid arthritis and diabetes) and continuous and repetitive hand or wrist movements. Carpal tunnel surgery is done to relieve the pain caused by the built up pressure. In order to do this, the transverse carpal ligament is cut. Nonsurgical carpal tunnel treatment options are recommended before the decision to undergo surgery is made.
The procedure can be done under GA or under local anaesthesia. The surgery site is anaesthetised with a local anaesthetic and is sterilised. The surgeon will make a small incision on the palm of the hand close to the wrist. The ligament that covers the carpal tunnel is located and cut to alleviate pressure on the median nerve. Tissue surrounding the nerves can also be removed if necessary. The incision is sutured closed once the procedure is complete. The wound will be heavily bandaged for up to a week.
The hand is normally non functional for 2 weeks as the wound heals slowly. Sutures are removed at 10 day. I usually advise not to operate both hands at the same time.
