Stenosing tenosynovitis, also known as trigger finger, is a condition in which one or more fingers get stuck in a bent position due to inflamed tendons. This is caused by prolonged repetitive movements or use of fingers or thumbs. The finger may suddenly straighten with a snap, like a trigger being pulled and released. Without proper treatment, the inflamed tendons can result in scarring that will limit the tendon’s ability to move properly.
- Signs and Symptoms
One of the most common symptoms of trigger finger is pain near the base of the finger or thumb. A painful snapping or clicking when trying to straighten or bend the finger is also a symptom. This symptom in particular often worsens over time, to the point where individuals may need to use care when straightening the affected finger or thumb.
- Diagnosing Trigger Finger
If you think you might have trigger finger, your best course of action is to schedule a visit with your doctor. During the office visit, your doctor will examine your fingers and hand, looking for any swelling or bumps near the joints. Severe trigger finger cases are simple to diagnose, as the affected finger will likely be locked, bent, or stiff.
Patients who have been diagnosed with trigger finger are often instructed to rest their affected finger and sometimes need to use a hand splint to immobilize the joint. In more severe cases, involving prolonged inflammation, drugs may be prescribed, or steroid injections might be injected into the tendon to help relieve discomfort and pain. If the condition persists, surgery may be necessary.
