Trigger finger, also known as stenosing tenosynovitis, is a condition in which one or more of your fingers or your thumb catches in a bent position. Your finger or thumb may straighten with a snap like a trigger being pulled and released. In severe cases, your finger may become locked in a bent position.
Often painful, trigger finger is caused by a narrowing of the sheath that surrounds the tendon in the affected finger. People whose work or hobbies require repetitive gripping actions are more susceptible. This condition is also more common in women than in men, and in anyone with diabetes.
Treatment of stenosing tenosynovitis varies depending on the severity. Many patients will respond to conservative treatment including functional rehabilitation and instrument assisted soft tissue technique (IASTM) a treatment that is very effective at breaking down the adhesions around that tendon. Kaizo Health offers dry needling which can also be effective and helpful in treating the condition.
