PER-16 Continuing with the method 1600, next a surgeon may deploy a fastener 1516 into the medial cuneiform 202 at an angle and orientation other than perpendicular to a surface of the bone. Next, a surgeon slides a second pivoting resection guide 1502b over the deployed fasteners (e.g., fastener 1516 and fastener 1516). Next, the surgeon deploys the cutting tool 1526 and resects the medial cuneiform 202. Finally, the surgeon brings the newly cut face of the first metatarsal 208 against the medial cuneiform 202 and fixates the two together for subsequent healing and recovery. In certain embodiments, the surgeon may rotate the first metatarsal 208 prior to fixation to further provide desired correction. Then method 1600 ends. Advantageously, the method 1600 can provide a minimally invasive procedure where the arms 1606 of the pin positioner 1602 remain above the skin. In such an embodiment, the procedure may be performed using three small incisions. 330 Added by DJM Jan 2024 1/3/24, 4:26 AM
