Provides an alternative to cortisone injection as in-office procedure
Initial management of trigger thumb in the office setting typically involves either cortisone injection into the flexor tendon sheath or percutaneous release of the involved pulley. However, both procedures have shortcomings, as reported in the literature. According to Kevin Kang, MD, cortisone injections have only a 57-percent effective rate, while percutaneous release may result in injury to the radial digital nerve of the thumb, scoring of the tendon, or inadequate release.
