Trigger Fingers

Other Names: Stenosing Tenosynovitis, Tendonitis.

What It Is: Tendons that bend the fingers are like cables and slide through very tight sleeves and tunnels in the hand. Any swelling in the
tendon or sleeve will prevent the smooth gliding and cause the tendon to get stuck in the tunnel. This results in the inability to bend or
straighten the finger as well as some pain.

Cause: This is usually caused by a degenerative process in the tendons. It can also result from inflammation which may be secondary to
repetitive trauma.

Treatment: Rest, splinting and therapy may take care of the problem. Sometimes a steroid (cortisone) injection can be of help; in fact,
approximately half of the cases are cured with a single injection. Occasionally, surgery is needed to relieve the pressure around
the tendons.
