The Efficacy of Steroid Injection in the Treatment of Trigger Finger

Trigger finger or flexor tenosynovitis is one of the most common reasons for referral to hand surgery outpatient clinics. The lifetime risk of developing trigger finger is be-tween 2 % and 3%.1) Patients frequently present with a painful triggering or clicking during active motion of an affected digit. This is due to the loss of normal smooth gliding of the tendon beneath the pulley system, most commonly at the level of the A1 pulley. This may be as a result of a nodule in the tendon or a diffuse swelling within the sheath as a result of a tenosynovitis. In 1953, Howard2) described the technique of steroid injection into the flexor sheath as an effective treatment. Background: Trigger finger is one of the most common reasons for referral to a hand specialist clinic. The purpose of this study is to investigate the efficacy of steroid injections for treating trigger digits
