Carpal Tunnel Syndrome (CTS) is a condition (disease) in which one of the nerves in the wrist is pinched. The place where the nerve is pinched is called carpal tunnel.
This tunnel consists of carpal bones and a transverse wrist band (retinaculum flexorum). Through the tunnel run the median nerve (wrist nerve) and nine flexor tendons from the forearm to the fingers and thumb.
The entrapment (place where the nerve is trapped) of the nerve can come when swelling of the tissues in and around the tunnel makes the pressure in the tunnel worse.
Complaints in carpal tunnel syndrome
Symptoms (signs) of CTS can vary quite a bit. For example, you may suffer from:
Often the symptoms can be relieved without surgery. In some cases, it helps to rest the nerve (at night). A detachable splint can help with this. This can be measured at the plaster room.
Sometimes your treating doctor may opt for a wrist splint along with an injection. This injection is placed in the palm side of the wrist and contains a strong anti-inflammatory (corticosteroids) and a small amount of anaesthetic (Lidocaine). This reduces swelling.
If all this does not help, surgery is necessary. An incision (small cut) is made in the wrist on the palm side. The roof of the carpal tunnel is split (cut lengthwise) to give the nerve more room.
