A technique for accurate and safe injection of steroid in trigger digits using ultrasound guidance.

Steroid injections have long been the main stay of conservative treatment of trigger digits. This procedure gives variable results, which is dependent on a number of factors. The injection of the steroid in the right place improves the success rate and also prevents complications associated with the procedure. We describe a technique using ultrasound for accurate injection of steroid to maximise its beneficial effects in treatment of trigger digits.
