Carpal tunnel syndrome causes pain and weakness in the hand due to pressure on the median nerve located inside the carpal tunnel in the wrist. The surgical procedure performed to relieve pressure on the nerve is called carpal tunnel decompression/release surgery.
It is commonly seen in individuals who perform repetitive wrist movements, for eg. computer work, typing, computer games, work using vibrating machinery, etc.
PROCEDURE
Surgery is done as an outpatient procedure under local anaesthesia.
An incision is given on the palm to expose the underlying structures. The carpal transverse ligament is cut to release the pressure on the median nerve and make more space for the tendons and nerves in that area. The skin and tissues are then closed with sutures.
This surgery can also be done endoscopically, in which a tiny camera is inserted through one incision and the operating instruments through another.
DURATION
The procedure takes about half an hour. After the surgery, the wrist will be in a splint for about a week to 10 days. Sutures are removed 10 to 14 days after surgery.
RECOVERY
After the splint is removed, a physical therapy program is started. Heavier activities with the affected hand are restricted for four to six weeks. Recovery times vary depending on the patient's age, general health, severity of CTS, and the length of time the symptoms have been present. Strength and sensation continue to improve over the ensuing year. Necessary alterations need to be made at home or workplace to prevent further problems.
RISKS
- Bleeding
- Infection
- Injury to nearby structures, like vessels and nerves
