Stenosing Tenosynovitis
Stenosing Tenosynovitis Causes
The condition is caused by a narrowing of the sheath surrounding the tendon in the affected finger.
Stenosing Tenosynovitis Definition
Stenosing tenosynovitis or trigger finger is a condition that catches the fingers or thumb in a bent position. The affected finger may straighten with a snap but may be locked in a bent position if the condition is severe.
Stenosing Tenosynovitis Symptoms and Signs
The affected finger may be stiff and click when moved. A bump or tenderness may appear at the base of the affected finger. If it becomes worse, the finger sometimes catches in a bent position and suddenly pops straight. It may later stay in a bent position.
Stenosing Tenosynovitis Treatment
Trigger finger treatment varies depending on its severity and duration. Mild cases are effective treated with rest, splinting, finger exercises, avoiding repetitive gripping, soaking in warm water, and massage. Serious conditions may be treated with doctor-recommended medications such as nonsteroidal anti-inflammatory drugs and steroids. Other cases may undergo percutaneous trigger finger release or surgery.
