There are two types of Tendonitis that effects the hands.
Hand Tendonitis - deQuervain's Tendonitis
deQuervain's Tendonitis is a condition
brought on by irritation or swelling of the tendons found along the thumb side of the
wrist (Figure 1). The irritation causes the compartment (lining) around the tendon to
swell, changing the shape of the compartment; this makes it difficult for the tendons to
move as they should. The swelling can cause pain and tenderness along the thumb side of
the wrist, usually noticed when forming a fist, grasping or gripping things, or turning
Hand Tendonitis - Flexor Tendonitis
Tendonitis is inflammation, irritation, and swelling of a
tendon, which is the fibrous structure that joins muscle to bone. Each finger have two
tendons. The tendons run along the palm side of the fingers and are very close to
the surface of the skin, particularly where the skin folds as you bend your fingers. The
tendons in the fingers are called flexor tendons. The longer tendon (flexor digitorum
profundus attaches to the last bone of the finger and bends the tip; the shorter tendon
(flexor digitorum sublimis) bends the middle joint of the finger.
