Two methods of non-incisional trigger finger release. A: Needle puncture sites and direction of the procedure (blue points indicate distal puncture sites, red points indicate proximal puncture sites, dotted lines indicate needle pathway under the skin, black arrow indicates the direction of the distal-to-proximal approach, and green arrow indicates the direction of the proximal-to-distal approach). B: The distal-to-proximal approach of non-incisional trigger finger release with ultrasound guidance. C: Looped Smartwire-01 with the distal-to-proximal approach before transecting the first annular pulley.
