Trigger Finger on Physical Exam

This is called the "trigger finger" or tendonitis of the finger flexors. In this condition, the finger locks in a folded position. Usually, the tendon moves easily in and out of its surrounding sheath when the finger stretches and flexes. However, when a tendon is very swollen, it cannot move easily inward when the finger is extended and therefore the finger is locked. To extend the finger, the person needs to force the swollen area back into the sheath, causing a clicking sensation similar to pulling a trigger. The cause of the trigger finger is unknown and is common among people with rheumatoid arthritis and diabetes.
