What is Trigger Finger?
Trigger finger is a condition that affects the tendons in the fingers or thumb, limiting movement of the finger. Typically, when attempting to straighten your finger, it locks or catches, before popping out in proper alignment.
The muscles that control the movement of the fingers and thumb are located in the forearm, above the wrist. These muscles are connected to the flexor tendons, which extend through the wrist and attach to the small bones of the fingers and thumb, controlling the movement of your digits. During the act of straightening or bending your finger, the flexor tendon slides through the tendon sheath, a snug tunnel that keeps the tendon in place next to the bones.
In trigger finger, the flexor tendon may become irritated as it slides through the tendon sheath. The tendon becomes thicker and stiffer as irritation increases, and nodules may form, making its passage through the tendon sheath more difficult. The tendon sheath itself may also thicken over time, tightening the space inside the tunnel. In cases of trigger finger, the tendon is momentarily jammed at the mouth of the tendon sheath tunnel, and when trying to straighten your finger, you may cause a “popping” or “snapping” sensation or sound as the tendon slips through the tight area, and the finger suddenly straightens.
In severe cases of trigger finger, the finger cannot be straightened, even with assistance, and one or more fingers may be affected.
What are the Causes and Symptoms of Trigger Finger?
The cause of trigger finger is unknown; however, there are factors that increase your risk of developing this condition, to include:
- Trigger finger occurs more frequently in women than in men.
- People between the ages of 40 and 60 are at a higher risk for trigger finger.
- Certain medical problems such as diabetes and rheumatoid arthritis also increase one’s risk.
- Activities that strain or stress the hand and fingers may contribute to trigger finger.
Typical symptoms of trigger finger usually begin without any identifiable injury, although they may sometimes follow a period of heavy activity that strained or stressed the hands or fingers. Symptoms usually include:
- A tender lump in the palm of the hand
- Painful inflammation
- A popping, catching or snapping sensation or sound in your finger or thumb joint when straightening the finger or thumb
- Pain, difficulty or discomfort, when bending or straightening the finger or thumb
How is Trigger Finger Treated?
Usually, trigger finger does not require surgery. In cases of mild symptoms, resting the finger may be sufficient to resolve the problem; in other cases, a splint to keep the finger in a neutral, resting position may help. Medications may also relieve pain and inflammation.
The decision to undergo surgery will depend on how severe the symptoms are, and whether non-surgical options have failed to relieve pain and restore normal function in the affected digit or digits. In cases where the finger is frozen in a bent position, surgery may be prescribed to prevent permanent stiffness.
In cases when surgery is recommended, the goal is to widen the opening of the tunnel to help the tendon slide through it more freely. This procedure may be done on an outpatient basis, using only local anesthesia.
