Commonly referred to as CTS, carpal
tunnel syndrome is the result of entrapment
of the median nerve at the wrist. More than
50 percent of the diagnosed cases of CTS are
thought to be work related. The entrapment
is caused by a rise in pressure of the
defined space where the median nerve
accompanies the flexor tendons as they pass
under the flexor retinaculum which is a
fibrous sheath to prevent fraying of the
tendons. Through some types of repetitive
movements such as typing, the consistent
flexion and extension at the wrist and
increased tendon sheath thickening give rise
to increased carpal tunnel pressure
resulting in pain and tingling in the hands.
The pain is worse sometimes at night. The
tingling can be well localized or diffuse in
the second and middle fingers. Abduction of
the thumb is sometimes weak or impaired
along with atrophy in more severe cases.
Tapping over the wrist at the base of the
palm causing a lightening sensation of
tingling in the hand is a good clinical
indication that a patient may have CTS.
