Open release of the A1 pulley is currently still regarded as the golden-standard procedure. Nevertheless, there is an increasing interest in minimally invasive percutaneous techniques for the treatment of this condition. Current techniques range from percutaneous needle techniques without imaging, to the use of hook knives, with ultrasound guidance. Because of concerns about possible complications or incomplete releases, hand surgeons remain wary. The objective of this study was to introduce a new ultrasound-guided percutaneous surgical technique for trigger finger release, using a second-generation minimally invasive surgical knife. In this series of 78 releases, complete resolution of the symptoms was found in 98.7% of the cases. One recurrence of triggering was observed. There were no tendon injuries, infections, or neurovascular lesions recorded. This paper contains technical pearls and possible pitfalls to ensure the surgeon of a complete release and to avoid complications. A video of the technique was also included as Supplemental Digital Content (http:\/\/links.lww.com\/BTH\/A143). We can conclude that the procedure can be considered as safe and highly effective for the treatment of triggering at the A1 pulley.<\/jats:p>","DOI":"10.1097\/bth.0000000000000367","type":"journal-article","created":{"date-parts":[[2021,8,27]],"date-time":"2021-08-27T00:00:44Z","timestamp":1630022444000},"page":"103-109","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":15,"title":["An
