Treatment of Trigger finger by ultrasound-guided needle release of a1 pulley: A series of 105 cases

•Trigger finger is a common and frequent pathology.•Ultrasound guided pulley release is fast and efficient.•This technique makes it possible to avoid a surgery. We aimed to evaluate the efficacy and tolerance of A1 pulley release using the needle technique, under ultrasound guidance, in patients with symptomatic trigger finger. All patients with symptomatic trigger finger underwent A1 pulley release using an intramuscular 21 gauge (G) needle. Quinnell grade (I-IV), Quick Disabilities of Arm, Shoulder & Hand (QuickDASH) score (0–100) and pain score on a visual analog scale (VAS: 0–10mm) were recorded at inclusion. The primary endpoint was complete resolution of the trigger finger at 6 months. Eighty-four patients totaling 105 treated digits were included. Mean age was 63.3±10.7 years. Prior to treatment, mean VAS pain score was 5.8±2.6mm, and mean QuickDASH score was 44.3±19.1. At 6 months, disappearance of symptoms was achieved in 85 of 91 digits with follow-up (93.4%), and in 85.7% at 12 months. The absolute reduction in VAS pain and QuickDASH scores at 6 months was respectively 4.1±3.1 (P
