Comparing the outcome of pediatric femoral neck fracture between Ti-Robot surgery and traditional surgery.

Abstract

To evaluate the efficacy of Ti-Robot system (Beijing TINAVI Medical Technology Company, China) compared with conventional surgery. We retrospectively analyzed 56 pediatric patients with femoral neck fractures. Patients ranged in age from 3.06 to 16.06 years. Twenty-six patients underwent Ti-Robot-assisted surgery, while thirty patients underwent freehand surgery. Baseline and intraoperative data were collected. During a follow-up period of at least 1 year, fracture healing and functional outcomes were assessed using radiographic evaluation and questionnaires. All patients were successfully fixed with three screws. Baseline characteristics were similar between the two groups. Screw parallelism and femoral neck width coverage were better in the Ti-Robot group. Intraoperative fluoroscopy frequency, radiation dose, drilling frequency, and total screw implantation time were lower in the Ti-Robot group than in the conventional group. There were no significant differences in operative time, intraoperative blood loss, healing time, complication rate, Harris Hip Score, Non-Arthritic Hip Score, or Hip and Groin Outcome Score between the two groups. The Ti-Robot system is a feasible adjunctive approach for the treatment of pediatric femoral neck fractures. It improves screw placement accuracy and reduces radiation exposure, although its effect on long-term clinical outcomes requires further investigation. Level III, retrospective cohort study.
