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.
Trigger finger may happen because a person performs the same manipulation over and over on a job, from squeezing and gripping during a weekend of heavy pruning and gardening, or from such hobbies as playing a musical instrument or crocheting. Trigger finger may also result from trauma or accident. The symptoms of trigger finger are pain in the fingers and popping sensations. Sometimes the finger may lock down into the palm or lock out straight. Symptoms are usually worse in the morning and improve during the day. Diagnosis. The diagnosis of trigger finger and thumb is obvious on physical examination. Often there is a click that can be felt as the nodule passes through the sheath.
