Brief Summary

Trigger finger is a common cause of hand disability and pain in the general population. It is a pathologic condition of the digital pulleys and flexor tendons. Although the pathogenesis is incompletely clear and multifactorial, the most common cause of the trigger finger is the thickened flexor tendon and/or thickened first annular (A1) pulley located at the metacarpophalangeal joint. Currently, ultrasound is considered an effective and valuable tool for assessing the trigger finger, providing static and dynamic evaluations of this condition and a comparison with the adjacent normal digits. Recently, it has been reported that ultrasound-guided percutaneous A1 pulley precise release using a needle knife has received increasing attention in the clinical treatment of trigger fingers and achieved good results. To our knowledge, this is the first clinical study comparing the efficacy and safety of ultrasonic-guided percutaneous A1 pulley release with a needle knife and the ultrasonic-guided steroid injection in treating trigger fingers.
