Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon. Symptoms of tenosynovitis include pain, swelling , and difficulty moving a particular joint where the inflammation occurs. When the condition causes the finger to "stick" in a flexed position, this is called "stenosing" tenosynovitis, which is commonly called "Trigger Finger."

When the finger tendon is inflamed, the synovium swells. Sometimes the tendon cannot slide easily through the synovium. When you straighten your finger, the tendon locks or sticks as it squeezes through the too-small synovium.

It usually occurs with tendinitis and it is related to stenosing tenosynovitis.

Symptoms

Symptoms of trigger finger range from pain where the finger or thumb joints join the palm, swelling, and locked joints.

Treatment

Possible treatments for tenosynovitis include cortisone injections and an outpatient surgery to enlarge the synovium. The hand is splinted for a week or so.

Causes

Causes of trigger finger are unknown. Repeated use of hand tools can precede the condition, as well as arthritis or injury. Trigger Finger sometimes runs in families, and is generally seen more often in males than in females. The causes for children are even less known and have a recurrence rate of less than 1-5% after treatment.

Trivia

Tenosynovitis brought the tennis career of Wimbledon champion Angela Buxton to an end at the age of 22.
