Trigger finger is a painful condition of the tendon and pulley system of the hand, and is medically known as stenosing tenosynovitis. Triggering can cause a finger to catch or lock in either a bent or extended position. When a triggering finger is forcibly flexed or extended a âsnapâ is sometimes felt.
In most cases, trigger finger is caused by repetitive gripping of the hand, or flexing of the thumb or forefinger. Those who are farmers, typists, industrial workers or musicians are particularly susceptible because they constantly repeat certain finger and thumb movements.
