Key Takeaway
Ti-Robot-assisted fixation of pediatric femoral neck fractures improved screw parallelism and reduced intraoperative fluoroscopy frequency and radiation dose compared to freehand technique, but showed no difference in Harris Hip Score, complication rate, or healing time at minimum 1-year follow-up.

Summary
This study compared Ti-Robot-assisted versus freehand percutaneous triple-screw fixation for pediatric femoral neck fractures in 56 patients aged 3–16 years. The Ti-Robot group demonstrated superior screw parallelism, greater femoral neck width coverage, fewer fluoroscopy exposures, lower radiation dose, fewer drilling attempts, and shorter total screw implantation time. No differences were detected in operative time, blood loss, healing time, complication rate, Harris Hip Score, Non-Arthritic Hip Score, or Hip and Groin Outcome Score.
Key Limitation
Minimum 1-year follow-up is insufficient to capture the most clinically significant complications of pediatric femoral neck fractures—osteonecrosis and physeal arrest—which may manifest years later, rendering the complication rate comparison premature.
Original Abstract
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.
