Early Radiological Outcome of MIS Bunionectomy With Guided Trajectory System

Early radiologic outcome and technical details of MIS bunionectomy using a guided trajectory system is reported here. From April 2022 to March 2023, 20 consecutive minimally invasive bunionectomies were performed on 17 female patients (bilateral in 3 patients) with an average age of 63.6 (range: 46 to 82). The mean IMA improved from 14.3 degrees (SD: 3.2) to 4.6 degrees (SD: 2.0), HVA from 28.2 degrees (SD: 6.3) to 6.7 degrees (SD: 2.8), DMAA from 16.6 degrees (SD: 5.6) to 6.6 degrees (SD: 1.8). Preoperatively, 17 feet (89.5%) were in TSP grades 2 and 3. Postoperatively, 19 feet (95%) improved to either TSP grades 0 and 1. The mean duration of operative time was 50 (SD: 9.25, range: 23 to 65) minutes. No intraoperative complications were reported. Overall, this study provides valuable insights into the benefits of using a guided trajectory system to improve the success of bunion correction surgeries. Level of Evidence: Level IV.
