Assessment of short‐term response and review of technique of ultrasound‐guided percutaneous A1 pulley release for the treatment of trigger finger

Abstract

Ultrasound‐guided percutaneous first annular pulley (A1) release is a non‐surgical management for the treatment of trigger finger, also known as stenosing tenosynovitis. Trigger finger occurs secondary to inflammation and retinacular sheath hypertrophy with subsequent restriction of the flexor tendons. Trigger finger can have a marked functional impact, with current conservative measures including steroids and/or splinting, and surgical therapy involving open release.
