摘　　要：目的探讨数字骨科3D重建技术辅助空心加压螺钉内固定术治疗GardenⅠ~Ⅱ型股骨颈骨折临床效果。方法回顾性分析2011年6月~2019年6月我院收治的44例GardenⅠ~Ⅱ的股骨颈骨折患者临床资料,按手术方案不同分为对照组和观察组,对照组22例在常规X射线及CT阅片后行股骨颈骨折空心加压螺钉内固定治疗;观察组22例术前根据Mimics软件建立骨折模型、分割骨折碎块、模拟手术复位并运用3-matic重建螺钉,在Mimics中最佳螺钉置入角度、螺钉长度后行股骨颈骨折空心加压螺钉内固定治疗。比较两组患者的手术操作时间、总透视次数、术中总失血量、骨折完全愈合时间、术后负重时间以及术后半年Harris髋关节功能评分。结果观察组手术操作时间短于对照组,总透视次数及术中总失血量少于对照组,差异有统计学意义(P<0.05);两组骨折完全愈合时间、术后负重时间以及术后半年Harris髋关节功能评分比较,差异无统计学意义(P>0.05)。结论将数字骨科3D重建技术应用于GardenⅠ~Ⅱ型股骨颈骨折术中,可在术前模拟空心螺钉进钉位置,提前确定螺钉型号及螺钉长度,减少患者的总透视次数、缩短手术操作时间、减少术中总失血量及降低螺钉位置失准发生率。Objective To investigate the clinical effect of digital orthopedics 3D reconstruction technology assisted hollow compression screw internal fixation in treatment of GardenⅠ-Ⅱfemoral neck fractures;Methods A retrospective analysis of 44 patients with GardenⅠ-Ⅱfemoral neck fractures admitted to our hospital from June 2011 to June 2019 was made.They were divided into control group and observation group according to different surgical schemes.The 22 cases in the control group were treated with internal fixation with hollow compression screws for femoral neck fracture after conventional X-ray and CT reading;22 cases in the observation group were treated before according to Mimics software,a fracture model was established,fracture fragments were segmented,surgical reduction was simulated,and 3-matic reconstruction screws were used.The optimal screw placement angle and screw length in Mimics were followed by internal compression fixation of hollow compression screws for femoral neck fractures.The operation time,total number of fluoroscopy times,total intraoperative blood loss,complete fracture healing time,postoperative weight-bearing time,and Harris hip function scores at half a year after surgery were compared between the two groups.Results The operation time of the observation group was shorter than that in the control group,and the total number of fluoroscopy times and total intraoperative blood loss were less than those in the control group,the differences were statistically significant(P<0.05).There were no significant differences in complete fracture healing time,postoperative weight-bearing time,and Harris hip function scores at half a year after surgery between the tow groups(P>0.05).Conclusion Applying digital orthopedic 3D reconstruction technology to GardenⅠ-Ⅱfemoral neck fracture surgery,it can simulate the position of the hollow screw before operation,determine the screw type and screw length in advance,reduce the total number of fluoroscopy times,shorten the operation time,and reduce the total
