Trigger Finger Corticosteroid Injection With and Without Local Anesthetic

Trigger Finger Corticosteroid Injection With and Without Local Anesthetic; a Randomized, Double Blind Controlled Trial

Steroid injection is the first line treatment for trigger finger. Steroid injection is sometimes mixed with a local anesthetic.

The treatment of trigger finger involves an injection of corticosteroid. Corticosteroid treats the underlying inflammatory pathology. Some surgeons add lidocaine with epinephrine as a local anesthetic with the injection. Lidocaine with epinephrine is associated with a burning sensation and may be the primary pain associated with the injection. We hypothesize that a corticosteroid injection without lidocaine with epinephrine will be less painful, and equally effective in treating trigger finger

Inclusion Criteria:

• At least 18 years old with trigger finger

Exclusion Criteria:

• Preference for open trigger finger release
• Not a candidate for corticosteroid injection
• Contraindication to lidocaine with epinephrine
