Trigger
finger is a common condition, characterized by a "snapping" of the finger. This is a tenosynovitis (local inflammation of the tendons and surrounding connective tissues) of the tendons that pull the finger inward toward the palm (flexion). The affected finger is locked in a bent position.

Trigger
finger usually occurs in middle-aged individuals or young children. The first symptom is tenderness at the base of the finger. There may be a palpable knot resulting from the scarring of the tendon and sheath. The locking can be released by a strong effort or by extending the finger with the other hand. If the condition worsens, the finger will not extend at all.

- The cause of tenosynovitis is uncertain. Other underlying diseases such as Rheumatoid Arthritis, gout, and diabetes can be associated with trigger finger
- Finger locking -- the local
inflammation of the tendon and sheath (the tunnel like
structures surrounding tendon) causes scarring and
constriction. This condition interrupts the free
gliding of the tendons within the sheath.

- Stretching of the affected finger, ice and anti-inflammatory drugs may be helpful during the initial period.
- Injection of steroids -- most patients are cured by a local injection of steroids around the tendon sheath, which relieves the inflammation and swelling
- Surgery-if the steroid injection does not work, a surgical release may be indicated. The procedure is done under a local anesthesia, and takes only a few minutes. The prognosis is favorable.
