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

PURPOSE: To evaluate the efficacy of Ti-Robot system (Beijing TINAVI Medical Technology Company, China) compared with conventional surgery. METHODS: 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. RESULTS: 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. CONCLUSION: 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 OF EVIDENCE: Level III, retrospective cohort study.
