The hand is composed of many small
bones called carpals, metacarpals and phalanges. The two bones of
the lower arm, the radius and the ulna, meet at the hand to form
the wrist. The distal radius is the most common fractured bone in
adults. The Median and Ulnar nerves are the major nerves of the
hand, and these nerves are responsible for movement, strength, and
sensation. Both nerves can become compressed or irritated leading
to compressive neuropathies, carpal tunnel syndrome or cubital tunnel
syndrome. In addition, many flexor and extensor tendons cross the
wrist and hand, and these tendons function to move the wrist and
digits. These tendons commonly become inflamed, tenosynovitis, or
they can catch or "trigger".
COMMON HAND PROBLEMS
Carpal
Tunnel Syndrome is caused by compression of the median nerve
at the wrist. The most common symptoms include numbness and tingling
in the hand, especially at night. In addition, common complaints
include pain and clumsiness with use of the affected hand.
Ganglion
Cysts are the most common mass found on the hand or wrist. These
are fluid-filled sacs that arise from irritated tendon sheaths or
joint linings. They commonly will resolve on their own or wax and
wane in size.
Trigger
Finger is caused by irritation of a sheath that surrounds the
flexor tendon of the finger. This sheath can pinch the flexor tendon
when attempting to flex the finger causing a snapping or locking
sensation of the tendon.
