Abstract:
Objective To evaluate the clinical efficacy of robot-assisted navigation with percutaneous lag screw treatment for Hangman's fracture.Methods We retrospectively analyzed the clinical data of 5 patients treated with robot-assisted C2 percutaneous lag screw for Hangman's fracture in our hospital from September 2021 to August 2023.Patients were positioned with moderate head-neck flexion in a Mayfield head clamp.After closed reduction with manual traction under general anesthesia,the C2 percutaneous lag screws were implanted under TINAVI orthopedic surgical robot assistance.Postoperative cervical CT scans were used to assess screw placement accuracy and fracture healing quality.Clinical efficacy was evaluated by the Odom grading system.Results All the 5 patients were operated successfully without vertebral artery injury or neurological complications.A total of 10 screws were implanted.According to the Gertzbein-Robbins standard,9 screws belonged to the grade A,and 1 belonged to the grade B,with an accuracy of 90％(9/10)and an excellent rate of 100％(10/10).The neck incision length ranged 20-30 mm(mean,27 mm).The operation time was 86-160 min(mean,112.8 min).The intraoperative blood loss was 10-50 ml(mean,30 ml).The postoperative hospitalization was5-18 d(mean,8 d).The patients were followed up for 12-34 months(mean,23.6 months).All fractures healed without screw breakage or loosening.According to the Odom grading,4 cases were excellent,and 1 case was good.Conclusion Robot-assisted navigation C2 percutaneous lag screw treatment for Hangman's fracture is accurate and minimally invasive,safe and effective.
