Trigger Finger - Stenosing flexor tendon tenosynovitis
There is a change in the slip between the tendon and the A1 pulley, causing the movement to become blocked. Most of the time it is due to pulley or tendon hypertrophy, but in some cases it may be due to pulley or tendon cyst.
It is more common in women than in men, and diabetes is a risk factor.
The classic frame is the one shown in the video, with locking when flexing the finger. In the lightest cases, the patient may have only pain at the pulley site, without locking; and in the most advanced cases you may not be able to perform active extension, only with assistance or even not be able to extend.
The diagnosis is clinical, and can be complemented with ultrasound. Ultrasound can show the presence of an associated cyst, which decreases the success rate of non-surgical treatment.
Treatment can be conservative or surgical, and the decision is on a case-by-case basis.

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.
