Trigger finger is a common condition usually curable by a safe, simple corticosteroid injection. Trigger finger results from a stenotic A1 pulley that has lost its gliding surface producing friction and nodular change in the tendon. This results in pain and tenderness to palpation of the A1 pulley, progressing to catching and then locking. Splinting for 6 to 9 weeks produces gradual improvement in most patients as does a quick steroid injection with the latter resulting in resolution of pain in days and resolution of catching or locking in a few weeks. Percutaneous or open release should be reserved for injection failures particularly those at high risk for continued injection failure including diabetics and those with multiple trigger fingers. We present a step-by-step method for injection with illustrations to encourage primary care providers to offer this easily performed procedure to their patients.
