Trigger Fingers

Trigger finger is characterized by a snapping or locking of the fingers (or thumb) as you try to open or close your fist. It is also known as stenosing tenosynovitis. What is actually happening is the tendon that facilitates the opening and closing of the finger is limited in its motion, causing the finger to pop or even lock. The tendons that control the movement of the fingers normally slide easily through a tunnel of tissue called a pulley. If there is swelling from inflammation or scarring around the tendons, the tendon has difficulty moving through the sheath. A pop may be felt as the tendon slips past the narrowed or tight space, or the finger may simply lock in place. In extreme cases, the finger cannot even be straightened. The stiffness or locking tends to worsen with inactivity, such as upon waking in the morning, and can be relieved with activity. Symptoms of trigger finger often include pain at the base of the finger or in the palm of the hand, a small lump, or the persistent painful popping and locking of your finger joints. Trigger finger can occur on its own or be associated with illnesses that cause changes in tissues, such as rheumatoid arthritis, gout or diabetes. Of course, it is best to avoid strenuous activities that aggravate the condition.

Standard treatment options include stretching, applying ice, taking anti-inflammatory medications or receiving steroid injections. If conservative measures have been exhausted, surgery may be recommended to prevent permanent stiffness. Surgery is usually done on an outpatient basis with the goal to simply release the pulley so the tendon can slide through it more easily. Most people experience movement of the finger immediately after surgery, though complete recovery, including relief from soreness and swelling, may take several weeks.
