Extensor Tendon Injuries

Extensor tendons, located on the back of the hand and fingers, allow you to straighten your fingers and thumb. These tendons are attached to muscles in the forearm. As the tendons continue into the fingers, they become flat and thin.

Flexor Tendon Injuries

The muscles that bend or flex the fingers are called flexor muscles. These flexor muscles move the fingers through cord-like extensions called tendons, which connect the muscles to bone.

Rotator Cuff Injuries

The rotator cuff is the confluence of the tendons of four muscles that encompass the ball joint (humeral head) of the shoulder. The rotator cuff has two functions. It provides stability to the shallow shoulder (glenohumeral) joint. Its second function is to provide motors (muscles) to move the shoulder. As time passes and we age, so does the rotator cuff. The rotator cuff tendon degenerates with age.

Tennis Elbow

Tennis Elbow is an inflammation of the tendon fibers that attach the forearm extensor muscles to the outside of the elbow. Pain may be felt where these fibers attach to the bone on the outside of the elbow or along the muscles in the forearm. Pain is usually more noticeable during or after stressful use of the arm.

Trigger Finger

Trigger finger/thumb happens when the tendon develops a nodule (knot) or swelling of its lining. When the tendon swells, it must squeeze through the opening of the tunnel (flexor sheath) which causes pain, popping, or a catching feeling in the finger or thumb.
