| 目的 探讨3D打印导向模板辅助下置入空心钉治疗股骨颈骨折的临床效果。方法 回顾性分析2015年3月至2017年12月在我院诊断为股骨颈骨折且需手术的病人，根据手术方式不同进行分组，每组40例。观察组采用3D打印导向模板植入3枚空心钉，对照组采用传统置钉导向器植入空心钉。两组病人均在骨科牵引床辅助“C”型臂X线机透视下完成手术，比较两组的置钉时间、术中导针穿针次数、术中X线透视次数和术中出血量。测量观察组术中所用置钉长度，并与术前通过3D打印模型测量所得的结果进行比较。结果 80例病人均顺利完成手术，未造成血管、神经损伤。观察组术中所用置钉长度与术前通过3D打印模型测量所得的结果相比，准确率在95%以上；观察组病人的置钉时间明显短于对照组，术中穿针次数、术中平均透视次数、术中出血量明显少于对照组（P＜0.05）。结论 3D打印导向模板辅助下置入空心钉治疗股骨颈骨折，有利于缩短手术时间，减少术中出血量，提高手术精度，达到良好的手术治疗效果，值得临床推广。 |

| Objective To investigate the clinical application of hollow nail implantation in the treatment of femoral neck fracture assisted by 3D printing guide template. Methods A retrospective analysis was performed on 80 patients with femoral neck fracture undergoing surgery from March 2015 to December 2017 in our hospital, and the patients were divided into experimental group and control group according to the inclusion or exclusion criteria and surgical methods (n=40 in each group). The patients in experimental group were treated with the implantation of three hollow nails assisted by 3D printing guide template, and those in control group were treated with the implantation of the hollow nails assisted by traditional screw guider. Both groups of patients were completely operated on under the help of C-arm perspective assisted by traction bed. The time of implanting hollow nails, the number of needle puncture during operation, the number of X-ray perspective during operation and the amount of bleeding during operation were compared between two groups. The length of planting hollow nails used during the operation in the experimental group were measured and compared with that measured by the 3D printing model before operation. Results All 80 patients were given the operation successfully, and no blood vessel and nerve damage caused in all cases during operation. The length of planting hollow nails used during the operation in the experimental group was compared with that measured by 3D printing model before operation, and accuracy rate was more than 95%. The time of planting hollow nails in the experimental group was significantly shorter than that in the control group, and the number of needle puncture during operation, the average number of X ray perspective during operation and the amount of intraoperative hemorrhage were significantly reduced as compared with those in the control group (P＜0.05). Conclusion 3D printing guide template assisted placement of cannulated screws for the treatment of femoral neck fractures is beneficial to shorten the operation time, reduce the amount of bleeding, improve the accuracy of surgery, and achieve a satisfactory surgical treatment effect. It is worthy of clinical promotion. |
