TO CONDITIONS TREATED
The biceps muscle, in the
front of the upper arm, helps stabilize the upper arm bone (humerus)
in the shoulder socket. It also helps accelerate and decelerate
the arm during overhead movement in activities like tennis or
pitching. Strong, cord-like structures called tendons connect
one end of the biceps muscle to the shoulder in two places. At
the other end of the muscle, tendons connect the biceps muscle
to the smaller bone (radius) in the lower arm. If the tendons
become inflamed or irritated, the condition is called tendinitis.
Injuries to the biceps tendons are commonly caused by repetitive
overhead activity.
Symptoms include:
•Pain when the arm is overhead or bent.
•Localized tenderness as the tendon passes over the groove in
the upper arm bone.
•Occasionally, a snapping sound
or sensation in the shoulder area.
