Trigger Finger: Causes, Symptoms and Treatments

Many people who regularly repeat certain finger and thumb movements, particularly pinching-style movements, are at risk of developing Trigger Finger (a.k.a. stenosing tenosynovitis). Trigger finger is an orthopedic condition that involves inflammation and swelling around the tendons that bend the finger. The tendons glide through a protective covering called a sheath, which is lined with a thin membrane that helps reduce friction. However, when inflamed, the membrane can thicken to several times its normal size, thereby preventing the tendons from gliding freely through the sheath.

The result can be “triggering”, painful snapping, or locking of the finger or thumb when bent because the swollen portion of the tendon gets caught on the opening of the sheath. When this happens, straightening the finger or thumb may require using the non-affected hand to pull the finger back into an extended position, causing another painful snap as the swollen portion of the tendon passes back into the sheath.

In the following video, Annie Muehlberger, APRN, RN – a nurse practitioner who works alongside Dr. Brian Divelbiss and Dr. Mark Winston to care for patients with hand, wrist and elbow conditions – explains more about Trigger Finger, including surgical and nonsurgical treatment options:
