Trigger finger, also known as stenosing tenosynovitis, is a condition where one or more fingers get stuck in a bent position. The finger may bend or straighten with a snap – like a trigger being pulled and released. The condition occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. According to the British Society for Surgery of the Hand, this condition is pretty common, with a 2-3% prevalence in the general population. However, it's even more prominent among certain groups. For example, people with diabetes are more prone to trigger finger, with the incidence rate rising to 10-20% within this group.
