Abstract:
Objective To verify the feasibility and safety of three-dimensional(3D)image acquisition by C-arm combined with orthopedic robot-assisted iliosacral screw fixation through S3 vertebra.Methods From July 2023 to June 2024,a total of 4 patients with closed pelvic fracture were surgically treated.Preoperative pelvic CT 3D reconstruction showed the presence of an ideal iliosacral screw bone channel through S3 vertebra which required screw fixation.There was no such channel through the S1 vertebra,or the stability of fixation through the S3 channel was better than that through the S1 channel.The 3D image acquisition by C-arm combined with orthopedic surgical robot was used to insert screws.Follow-ups were conducted for at least 6 months after surgery to assess fracture healing and limb function.Results All the 4 patients were successfully implanted with a S2 and a S3 iliosacral screw,and all the 8 screws did not penetrate the cortical bone.Three cases had excellent Majeed scores and 1 case had good scores at 3 months after surgery.Follow-ups were conducted for 18,12,7,and 6 months after surgery,respectively,and all fractures healed smoothly without any loosening or breakage of screws.Conclusion 3D image acquisition by C-arm combined with orthopedic robot-assisted iliosacral screw fixation through S3 vertebra is feasible,safe and effective.
