The frequency of carpal tunnel syndrome diagnosis has been increasing due to higher rates of computer use and other actions commonly attributed to the development of the condition. The source of carpal tunnel syndrome’s pain and numbness is increased pressure on the median nerve, which runs through the wrist and the center of the hand.
The carpal tunnel in the wrist is a roughly inch wide passage flanked by the carpal bones. This tunnel is designed to protect the median nerve and the flexor tendons that run through it. These tendons are what allow people to bend their fingers and thumbs. Because this tunnel is surrounded by bone and relatively rigid connective tissue, there is very little room for expansion.
Increased pressure is put on the median nerve when the carpal tunnel narrows or when the synovium tissues surrounding the flexors are irritated and swell.
Non-surgical treatment options include bracing or splinting, anti-inflammatory drugs, corticosteroid injections and changes in behavior, such as refraining from activities that cause the swelling. There are also certain exercises that can help promote better movement for the flexors and nerves within the carpal tunnel.
If non-surgical treatments are ineffective at relieving pain, open carpal tunnel release or endoscopic carpal tunnel release surgery may be suggested. During both procedures, the transverse carpal ligaments – the fibrous, rigid roof of the carpel tunnel – will be divided to create more room in the carpal tunnel and relieve pressure.
The endoscopic variant of the procedure offered by Dr. Barbour is the less invasive option and is performed with a miniature camera and specialized instruments to minimize soft-tissue trauma and decrease recovery time.
