Overview of Procedure
Carpal tunnel surgery is a procedure involving opening up the wrist and relieving the median nerve of pressure in order to relieve pain, weakness, and sense disturbance caused by Carpal Tunnel Syndrome.
The wrist contains a sheath of connective tissue that surrounds and protects tendons and nerves, including the median nerve, which runs down the length of the arm and forearm. The space between this sheath and the bones is the carpal tunnel. When the median nerve endures excessive pressure, for example, because of fluid retention or swelling of an inflamed tendon, the result can be a painful condition known as Carpal Tunnel Syndrome. Patients with Carpal Tunnel Syndrome often complain of aches, “pins and needles”, burning or numbness.
The Right Candidates
Depending on the severity and length of symptoms, a good candidate for carpal tunnel surgery is one who has had the symptoms for 10 or more months. These symptoms include, pain, numbness and tingling.
Risks and Side Effects
While carpal tunnel release surgery is very common, it does come with some risks. Some individuals who have this surgery lose strength in their wrist while others experience nerve damage or stiffness in the wrist and hand. There is also a risk of infection as a result of the surgery.
Surgery
Corrective surgery can be performed by a neurosurgeon or hand surgeon, and typically follow a treatment of anti-inflammatory drugs which proved to be unsuccessful. The surgery can be open hand or endoscopic, and involves relieving pressure on the median nerve by cutting the carpal ligament. It is done with a local anaesthetic, so you are awake for the procedure.
Recovery
The surgery is an outpatient procedure so you can go home the same day. You may be prescribed pain medication. You should avoid lifting anything heavier than 5 kg for two months after the surgery.
Results
Success rate is high, with most patients able to return to work and normal activities within 6 weeks. Grip strength is typically diminished, but returns after a few months. Your scar may feel tender for a few months.
