Trigger Finger Injection
These video details a common procedure that is performed in the orthopedist’s office known; a trigger finger injection. Trigger finger, or thumb, is a common hand alignment that most commonly effects the ring and long fingers, causing pain and catching of the digits. The cause is a tissue pulley that secures the flexing tendons of the hand. These pulleys, known as the A1 pulleys become inflamed, swells and causes the catching and pain. The common injectant, in our office, is Depo-Medrol, a steroid, and numbing medication. The goal of the steroid is to reduce inflammation in the pulleys and stop the symptoms. The numbing medication will also give short term pain relief. This may last for a few hours.
Side effects include pain, slight chance of infection, skin discoloration, flushing of the skin, and if you are diabetic may increase your blood sugar levels. Pain relief usually starts one to two weeks after the injection, and can last 6 weeks to 6 months depending on the severity of the inflammation. If the injection fails, the next step would be a release of the A1 pulley. This is a simple out-patient procedure.
