摘要
目的探索自主研发的智能机器人辅助骨折复位系统(RAFR)在股骨颈骨折闭合复位中的应用,验证其有效性和临床可行性。方法采用3D打印技术,基于首都医科大学附属北京积水潭医院创伤骨科2024年6月至2024年12月12例真实股骨颈骨折病例CT影像数据,制作头下型、经颈型和基底型骨折模型各4例。应用RAFR系统进行模拟复位试验,复位后通过X线片和CT影像测量“类Garden指数”、前倾角、颈干角及皮质骨偏差,评估复位精度和复位质量。结果12例模型均成功复位,复位后类Garden指数正位(167.4±1.4)°,类Garden指数侧位(179.9±0.5)°,颈干角(121.8±1.9)°,颈干角误差(1.7±1.2)°,复位精度(1.0±0.5)mm,前倾角19.3(19.2,19.4)°,前倾角误差0.1(0.0,0.2)°,皮质骨偏差2.4(0.0,5.0)mm,复位结果均符合临床手术要求。结论RAFR能够有效辅助股骨颈骨折的闭合复位,具有较高的复位精度和操作可行性,为股骨颈骨折的微创治疗提供了一种新的技术手段,具有广阔的临床应用前景。
Objective To explore the application of a self-developed intelligent robot-assisted fracture reduction system(RAFR)in the closed reduction of femoral neck fractures through model experiments,and to verify its effectiveness and clinical feasibility.Methods Using 3D printing technology,based on data of CT imaging from 12 real femoral neck fracture cases from June 2024 to December 2024 in Departmemt of Orthopaedic Trauma,Beijing Jishuitan Hospital,Capital Medical University,4 models each of subcapital,transcervical,and basicervical fractures were created.The RAFR system was used to conduct simulated reduction experiments.Post-reduction,X-ray and CT imaging were used to measure the"Garden-like index,"D0I:10.19548/j 2096-269x.2025.04.002 anteversion angle,neck-shaft angle,and cortical bone deviation to evaluate reduction accuracy and quality.Results All 12 models were successfully reduced.Post-reduction measurements were as follows:Garden-like index in the anteroposterior view(167.4±1.4)°,Garden-like index in the lateral view(179.9±0.5)°,neck-shaft angle(121.8±1.9)°,neck-shaft angle error(1.7±1.2)°,reduction accuracy(1.0±0.5)mm,anteversion angle 19.3(19.2,19.4)°,anteversion angle error 0.1(0.0,0.2)°,and cortical bone deviation 2.4(0.0,5.0)mm.All reduction results met clinical surgical requirements.Conclusions The intelligent RAFR can effectively assist in the closed reduction of femoral neck fractures,demonstrating high reduction accuracy and operational feasibility.It provides a new technical approach for the minimally invasive treatment of femoral neck fractures and holds broad prospects for clinical application.
