Trigger finger injections offer a non-surgical solution to alleviate pain and stiffness, restoring smooth finger movement by reducing inflammation in the affected tendon sheath.
How Are Trigger Finger Injections Performed?
The procedure is quick and usually done in an outpatient setting. After cleaning the injection site, a local anesthetic may be applied to minimize discomfort. Then, using a fine needle, the doctor injects a corticosteroid directly into the tendon sheath of the affected finger or thumb. The goal is to reduce inflammation and swelling, allowing the tendon to glide more freely.
The corticosteroid’s primary therapeutic goal is to relieve trigger finger pain and restore normal movement in the affected digit. It can also serve a diagnostic purpose, as improvement after the injection confirms that inflammation within the tendon sheath is the source of dysfunction.
