Trigger finger causes a finger to be stuck in a bent position, making it difficult for a person to straighten the finger. Trigger finger typically affects women more than men and most often occurs in those ages 40 to 60. Those who have diabetes, rheumatoid arthritis, or whose hobbies or work require repetitive gripping motions are susceptible to trigger finger.
Symptoms and Causes
People who experience trigger finger may experience a catching or popping sensation when straightening or bending the finger. If the condition advances, the finger may become locked in that position and will not straighten. This is due to narrowing of the cavity (called the tenosynovium) that is around the tendons in the finger. As the tenosynovium becomes inflamed and enlarged, the tendons can no longer function properly and begin to catch while attempting to straighten the finger. Over time, the tendon itself can become irritated, meaning the finger can no longer straighten.
First Steps
At the first signs of trigger finger (catching or pain at the base of the finger), a person should make lifestyle modifications. If she performs regular gripping, such as holding a power tool or gardening shovel, taking a break or frequent breaks throughout the course of the day may relieve pain and prevent advancement of the condition. However, if the pain persists or worsens, a doctor should be consulted. Additional options include stretching the finger, applying ice, or taking anti-inflammatory medications, such as ibuprofen, naproxen or others.
However, if the trigger finger is more than likely caused by a medical condition, seek advice from a physician.
Medical Treatments
A doctor can evaluate the joint and determine the seriousness of the trigger finger. If the finger is hot to the touch or swollen, this may indicate an underlying condition of rheumatoid arthritis.
If the trigger finger causes pain, but is not locked, a physician may use cortisone injections to reduce inflammation. Prescription-strength nonsteroidal anti-inflammatory drugs (NSAIDS) may also be prescribed to aid in pain and swelling.
In the most severe cases of trigger finger, surgery may be used. There are two types of procedures. Percutaneous trigger finger release is a procedure that involves creating a small incision in the palm or inserting a needle to the finger and widening the inflamed tunnel that is restricting the tendon. The second option is surgical release, which involves making a larger incision to release the tendon, preventing locking of the finger permanently
