3D打印技术在股骨粗隆间骨折手术中的应用

目的 探讨3D 打印技术在手术治疗股骨粗隆间骨折中的临床价值。方法 回顾性分析2017年 2月~2019 年 2月于我院就诊的股骨粗隆间骨折患者58例，随机分为传统组和3D组，各29例。两组均实施切开复位锁定钢板内固定术，传统组采用传统影像学资料辅助完成手术，3D组应用3D打印技术辅助完成手术。比较两组术中透视次数、手术时间、术中出血量及患者术后Harris评分。结果 所有患者均顺利完成手术，3D组手术时间、术中透视次数、术中出血量均少于传统组，差异统计学意义显著（P＜0.01）；两组Harris评分比较，差异统计学意义不显著（P＞0.01）。结论 3D 打印技术有利于优化手术过程，能有效缩短手术时间、减少透视次数、减少出血量，降低了手术风险，临床效果满意。

Application of 3D Printing Technology in the Operation of Intertrochanteric Fracture

Objective To investigate the clinical value of 3D printing technique in the surgical treatment of intertrochanteric fractures.Methods A retrospective analysis of 58 patients with femoral intertrochanteric fractures who were treated in our hospital from February 2017 to February 2019 was randomly divided into the traditional group and the 3D group, 29 cases in each group. Both groups were treated with open reduction and locking plate fixation. The traditional group used traditional imaging data to assist the operation. The 3D group used 3D printing technology to assist the operation. The number of intraoperative fluoroscopy, operative time, intraoperative blood loss and Harris score were compared between the two groups.Results All patients underwent successful operation. The operation time, intraoperative fluoroscopy and intraoperative blood loss were lower in the 3D group than in the traditional group,the difference was statistically significant (P<0.01).There was no significant difference in Harris score between the two groups (P>0.01).Conclusion 3D printing technology is beneficial to optimize the surgical procedure, which can effectively shorten the operation time, reduce the number of fluoroscopy, reduce the amount of bleeding, reduce the risk of surgery, and satisfy the clinical results.
