Carpal Tunnel

Who does this affect? It is seen usually seen in the over 40s. Women are more commonly affected than men. It is associated with pregnancy, diabetes and thyroid disorders.

Symptoms This is a very common condition causing tingling, "pins & needles" or even pain in the fingers, hand and possibly up the forearm. It is often worse at night or on activity. It can be quite disabling and is caused by a trapped nerve in the wrist. The Median nerve passes through the Carpal Tunnel from the forearm to the hand, along with the flexor tendons. The nerve can be "squashed" in this enclosed space.

Investigations We recommend prompt examination to make an early diagnosis. This minimizes the risk of permanent nerve damage. Special tests (nerve conduction studies) may be required to confirm the diagnosis.

Non-surgical Treatment Initially, splints and injections can be used as an alternative to surgery. However, they often only provide temporary benefit.

Surgical Treatment Carpal tunnel release surgery is a minor operation under local anaesthetic performed as a day case. It increases the space in the carpal tunnel so taking the pressure of the nerve. The procedure is very successful in relieving symptoms. The BOSS upper limb surgeons have presented their excellent results from this procedure nationally and internationally.
