| 摘要: |
| 目的 观察一种新型的激光定位导航系统在辅助股骨颈骨折空心螺钉置入时能否减少导针穿刺次数、术中透视次数及提高置钉的准确性。方法 将20个由3D打印皮肤与人造股骨模型制成的大腿模型平均分配至传统C臂X线机透视引导组（传统组）和激光定位导航辅助组（导航组），每组10个。所有模型均按“平行、倒三角”的构型置入3枚导针。对两组的导针穿刺次数、术中透视次数及术后导针的平行度、分散度等进行统计学评价。结果 两组手术过程均顺利，60枚导针均成功置入，未穿出股骨颈皮质。导航组导针穿刺次数和术中透视次数均少于传统组[（5.3±1.8）次vs（7.5±2.3）次，P＝0.03；（10.8±2.7）次vs（18.5±2.7）次，P＜0.01]。导航组与对照组导针的平行度和分散度差异均无统计学意义（P均＞0.05）。结论 新型激光定位导航系统能减少股骨颈骨折闭合复位空心螺钉内固定术中导针穿刺次数和术中透视次数，但对导针的平行度和分散度无明显改善。 |

| Abstract: |
| ObjectiveTo observe whether a new laser positioning and navigation system can reduce the total drilling attempts and the use of intraoperative fluoroscopy and improve the accuracy of guide pins when assisting cannulated screw placement in the femoral neck fractures.MethodsTwenty thigh models made using 3-dimensional printed skin and artificial femur models were equally divided into traditional C-arm X-ray fluoroscopic guidance group (traditional group) and laser positioning and navigation assistance group (navigation group), with 10 thigh models in each group. All models were placed with 3 guide pins in a "parallel and inverted triangle" configuration. The number of drilling attempts, the use of intraoperative fluoroscopy, and the parallelism and dispersion of guide pins were statistically evaluated after operation in the 2 groups.ResultsThe surgical procedures were uneventful in both groups, and all 60 guide pins were successfully placed without penetrating the femoral neck cortex. The numbers of drilling attempts and the use of intraoperative fluoroscopy in the navigation group were less than those in the traditional group (5.3±1.8 vs 7.5±2.3, P＝0.03; 10.8±2.7 vs 18.5±2.7, P < 0.01). There were no significant differences in the parallelism or dispersion of the guide pins between the navigation group and the control group (both P > 0.05).ConclusionThis new laser positioning and navigation system can reduce the drilling attempts and the use of intraoperative fluoroscopy, but cannot improve the parallelism or dispersion of guide pins. |
