Clinical Efficacy and Safety of CT Three-dimensional Reconstruction Technol-ogy-assisted Femoral Neck System Internal Fixation for Displaced Femoral Neck Fractures in Elderly Patients
摘要
Abstract
Objective:To investigate the efficacy and safety of CT three-dimensional reconstruction technology-assisted femoral neck system(FNS)internal fixation in the treatment of displaced femoral neck fracture(DFNF)in elderly patients.Methods:A total of 208 elderly patients with DFNF prospectively selected from January 2022 to August 2023,who were randomly assigned to a three-dimensional group and a conventional group,with 104 cases in each group.The three-dimensional group underwent CT three-dimensional reconstruction technology to assist FNS internal fixation surgery,while the conventional group underwent X-ray examination to guide FNS internal fixation surgery.The surgical conditions,surgical trauma indicators,fracture reduction quality,and postoperative recovery effects were compared between the two groups.Results:Intraoperative blood loss in the three-dimensional group was(43.68±6.20)mL,which was significantly reduced than that in the conventional group(50.39±8.77)mL(P<0.05),the duration of surgery,postoperative ambulation,hospitalization,and fracture healing time[(84.52±14.76)minutes,(6.38±1.55)days,(10.35±2.14)days,(3.86±0.21)months]were all shorter than those in the conventional group[(102.15±18.34)minutes,(8.16±1.71)days,(13.69±2.63)days,(4.07±0.25)months](P<0.05),the levels of serum CRP,TNF-α,and IL-6 on postoperative day 1 and 3 were lower in the three-dimensional surgery group than those in the conventional group(P<0.05),the postoperative fracture reduction quality,Harris score,and SF-36 score of hip joint function were superior to those in the conventional group(P<0.05).The complication rate in the three-dimensional group was 1.92%,which was lower than that in the conventional group(8.65%)(P<0.05).Conclusion:CT three-dimensional reconstruction technology-assisted FNS internal fixation can significantly optimize the surgical process,improve the quality of fracture reduction,promote postoperative recovery,and result in fewer complications,thus possessing clinical application value.关键词
