Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon. It is commonly called "Trigger Finger."
When the finger tendon is inflamed, the synovium swells. Then 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 tendonitis and it is related to stenosing tenosynovitis.
Symptoms of Trigger Finger range from pain where the finger or thumb joints join the palm, swelling, and locked joints.
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 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 reoccurance rate of less than 1-5% after treatment.
