Application of 3D printed surgical guide in the surgical treatment of complex ankle fractures
3D打印手术导板在复杂踝关节骨折手术治疗中的应用

摘要

目的 分析复杂踝关节骨折手术治疗中采取3D打印手术导板的效果。方法 选取我院于2020年10月-2022年6月收治的复杂踝关节骨折患者24例为本次研究对象。对上述患者采取3D打印技术设计个体化手术导板手术治疗。观察患者治疗效果。结果 24例患者术中用时（76.12±8.24）min，出血量（47.30±6.12）ml，X线照射次数（4.16±0.57）次，骨折愈合时间（14.36±1.07）周。患者术后1、3、6个月踝关节功能（AOFAS）评分分别为（75.28±4.13）分、（84.23±7.84）分、（92.53±8.72）分，其中术后3个月、6个月AOFAS评分相比较术后1个月较高，具有统计学含义（P＜0.05）。结论 在复杂踝关节骨折手术治疗中长采取3D打印手术导板治疗效果确切。此种方法值得进一步临床推广应用。

Abstract

Objective To analyze the effect of 3D printing surgical guide in the surgical treatment of com- plex ankle fractures.
Methods A total of 24 patients with complex ankle fractures admitted in our hospital from October 2020 to June 2022 were selected as the research objects. For the above patients, 3D printing technology was used to design individualized surgical guide surgical treatment. Observe the patient's treatment effect.
Results The intraoperative time of 24 patients was (76.12±8.24) min, the blood loss was (47.30±6.12) ml, the times of X- ray irradiation was (4.16±0.57) times, and the fracture healing time was (14.36±1.07) weeks. The ankle function (AOFAS) scores of the patients at 1, 3 and 6 months after operation were (75.28±4.13), (84.23±7.84) and (92.53± 8.72) respectively, of which 3 months and 6 months after operation The AOFAS score was higher than that at 1 month after operation, which was statistically significant (P<0.05).
Conclusion   In the surgical treatment of com- plex ankle fractures, the effect of 3D printing surgical guide is definite. This method deserves further clinical application.
