Trigger Finger
What is Trigger Finger?
Trigger finger is a condition in which one of the fingers or thumb catches in the bent position causing pain. Tendons aid in the motion of flexion and extension of fingers and slide though a tunnel like structure for a smooth motion. However, irritation of the tendons occurs, causing it to become thicker and sometimes form a node that prevents the tendon from passing easily through the tunnel inhibiting the finger to straighten.
What are the Risk Factors for Trigger Finger?
No one is really sure why trigger fingers occur. One theory is repetitive falling on an out stretched hand, causing irritation and inflammation of the tendons. More females are seen with trigger fingers than males are. People who are at greater risk may have other medical conditions such as rheumatoid arthritis or diabetes.
What are the Symptoms of Trigger Finger?
- Stiff finger, worse after activities
- Click/popping sensation with movement of joint
- Bump or tenderness at the base of the finger
- Pain in the palm
- Finger may become stuck in a bent position
When Should Someone Seek Medical Advice for a Trigger Finger?
Be sure to discuss with your doctor about any stiffness or catching of a finger. When a finger is stuck in the bent position and can no longer be straightened, medical care is needed to prevent permanent damage. Seek immediate medical care when a finger joint is warm to touch, red and swollen because it may be infected.
What is the Treatment for Trigger Finger?
Treatment for trigger finger depends on the severity and duration of problem. Conservative treatment for mild symptoms includes: rest the finger, limit activities, splint finger for a few weeks, soak in warm water for 5-10 minutes at a time several times a day, massage finger to help alleviate the pain, and take over-the-counter pain medications.
Surgery is the best approach when a finger is stuck in the bent position. This opens the tunnel allowing the tendon to slide through again, permitting the finger to straighten without difficulty. This is usually an outpatient procedure done though a small incision in the palm. Fingers can be moved immediately after the procedure is complete. Elevation of hand after surgery will help decrease swelling. If the finger was stiff or stuck for a prolonged period of time, occupational therapy may help regain all motion in finger post-operatively.
