Carpal Tunnel

The Carpal Tunnel is a structure on the wrist which comprises of carpal bones, a ligament sheath and the most important part of the tunnel is the median nerve. This nerve is the structure that becomes compressed causing the signs and symptoms into the hand and wrist.

The injury tends to happen when either the ligament structure around the wrist, i.e. the flexor retinaculum, becomes damaged or sprained, or when the carpal bones become restricted and increase pressure around the median nerve. The median nerve provides stimulus to the thumb and second, third and fourth digits. It can also be described as a repetitive stress injury to the wrist.
