骨科机器人辅助股骨颈动力交叉钉系统治疗股骨颈骨折

Orthopaedic robot assisted femoral neck dynamic cross fixation system for the treatment of femoral neck fractures

目的:比较骨科机器人辅助股骨颈动力交叉钉系统(femoral neck system,FNS)和传统徒手操作FNS治疗股骨颈骨折的临床疗效。方法:回顾性分析2021年6月至2022年6月北京积水潭医院智能骨科连续收治的62例<65岁股骨颈骨折患者的临床资料,按照是否采用骨科机器人辅助手术分为两组:试验组30例,年龄34~56岁,采用骨科机器人辅助导航,闭合或有限切开复位后行FNS内固定;对照组32例,年龄33~54岁,采用传统徒手操作,闭合或有限切开复位后行FNS内固定。分析比较两组住院时间、手术时间、术中出血量、术中透视次数。术后6个月采用髋关节Harris评分评估两组髋关节功能恢复情况。结果:62例股骨颈骨折均顺利完成手术。试验组和对照组术中出血量比较,差异无统计学意义(P>0.05)。试验组手术时间短于对照组[42.1(28.5,50.7)min vs.53.4(36.9,62.5)min,Z=-2.338,P=0.019];试验组术中X线透视次数少于对照组[8.0(6.0,11.0)次vs.15.0(13.0,17.0)次,Z=-5.960,P<0.001]。两组术后6个月随访时髋关节Harris评分比较,差异无统计学意义(P>0.05)。结论:与徒手操作FNS相比,骨科机器人辅助FNS治疗股骨颈骨折可缩短手术时间,减少术中透视次数,在髋关节功能恢复上两者治疗效果相当。

Objective To explore and compare the clinical efficacy of orthopedic robot assisted femoral neck system(FNS)and traditional manual FNS in the treatment of femoral neck fractures in middle-aged and young people.Methods The clinical data of 62 consecutive patients with femoral neck fracture and age less than 65 years old admitted to the Intelligent Orthopaedic Department of Beijing Jishuitan Hospital from June 2021 to June 2022 were retrospectively analyzed.According to whether orthopedic robot-assisted surgery the patients were divided into two groups:30 patients aged 34 to 56 years old were treated with orthopedic robot assisted FNS internal fixation after closed or limited open reduction(experimental group);32 patients aged 33 to 54 years old underwent FNS internal fixation after closed or limited open reduction(control group).The age,gender,time from injury to admission,average hospital stay,surgical duration,intraoperative bleeding volume,and intraoperative fluoroscopy frequency of two groups of patients were analyzed and compared.The hip joint function in both groups of patients was evaluated using the Harris hip joint scoring standard at 6 months after surgery.Results All 62 patients with femoral neck fractures successfully completed the surgery.There was no significant difference(P>0.05)between the experimental group and the control group in terms of baseline data such as age,gender,time from injury to admission,time from admission to surgery and the intraoperative bleeding.The surgical duration of the experimental group was significantly shorter than that of the control group[42.1(28.5,50.7)min vs.53.4(36.9,62.5)min,Z=-2.338,P=0.019].The intraoperative X-ray fluoroscopy frequency of the experimental group was significantly lower than that of the control group[8.0(6.0,11.0)times vs.15.0(13.0,17.0)times,Z=-5.960,P<0.001].In terms of postoperative hip joint function,there was no significant difference in Harris score between the two groups of patients at 6-month follow-up(P>0.05).Conclusion Compared with manual operation of FNS,orthopedic robot assisted FNS in the treatment of femoral neck fractures can help shorten surgical time,reduce intraoperative fluoroscopy frequency,and have similar therapeutic effects on long-term hip joint function recovery.
