The purpose of this review was to summarize the current literature pertaining to ultrasound‐guided percutaneous A1 pulley release procedures. We searched PubMed, Cochrane Library, Embase, and Web of Science for clinical studies examining ultrasound‐guided percutaneous A1 pulley release. A total of 17 studies involving 749 procedures were included in this review. The overall success rate was 97%. There were 23 minor complications (4 cases of hematomas, 15 cases of persistent pain, and 4 cases of transient numbness) and no major complications reported. Ultrasound‐guided A1 pulley release is an effective and safe procedure for the treatment of trigger fingers and thumb.
