Trigger Finger - The Snapping Digits

A trigger finger is a "snapping" condition of any of the digits of the hand when opened or closed. A trigger finger is a common problem that causes pain and catching. A trigger finger is noted when either the ring, middle, or index finger attempts to flex closed while gripping.

Trigger fingers are more common in women than men and are more common in people who have medical problems such as diabetes or rheumatoid arthritis.

Local swelling from inflammation or scarring around the tendons that normally pull the affected digit inward toward the palm causes trigger finger. The tendons that help to bend the fingers and thumb slide through a snug tunnel. Inflammation of the tendons can cause the opening of the tunnel to become smaller, or the tendon to thicken so that it does not slide easily through the tunnel.

As you try to straighten the finger, the tendon becomes momentarily stuck then pops as the tendon slips past the tight area. This causes pain as you try to move the finger. The symptoms of a trigger finger usually start without any injury. Often pain in the palm of the hand along with swelling or a small lump may be present. Stiffness and catching are usually worse in the morning or following periods of inactivity. Usually the tendon will loosen up with movement.

In severe cases the finger may become stuck in a bent position and cannot be straightened. A trigger finger can involve one or more fingers.

Treatment options for a trigger finger depend on the severity of the finger. For mild symptoms resting the finger may be enough to relieve the problem, Stretching, ice and anti-inflammation treatments can also be helpful.

For more severe cases cortisone injections may be prescribed. However, if the trigger finger persists after two injections and is not responsive to the treatment, surgical procedures to remove the inflamed or scarred tissue are considered.

Trigger finger is not a dangerous condition. Therefore deciding on treatment options is a personal one based on the severity of the symptoms. If you have a trigger finger see your doctor to discuss treatment options.
