【摘要】：目的采用3-D打印技术制造个性化复位型外固定器,探讨严重胫腓骨粉碎性骨折的治疗新方法。方法 2015年4月选择1例胫腓骨严重粉碎性骨折患者纳入研究。患者为男性,年龄18岁,身高171 cm,体质量67 kg。采用计算机辅助技术与3-D打印技术相结合,定制个性化外固定支架对其进行治疗,术后观察临床疗效。结果支架安装时间约10 min,术中无需透视,复位一次成功。术后双下肢恢复等长;复查X线片示远折端向后成角纠正了37°、外翻成角纠正了4°,胫骨骨折端对位对线良好,下肢力线完全矫正,与软件模拟复位后模型一致。术后未出现新的骨折移位,3.5个月后骨折临床愈合,8个月后达坚强骨性愈合;膝关节活动功能良好。结论应用3-D打印个性化外固定器治疗胫腓骨严重粉碎性骨折,具有操作方便、个性化程度高、复位效果好、固定牢靠、复位无需X线透视等优点。
[Abstract]:Objective to study the treatment of severe comminuted tibia and fibula fracture by using 3-D printing technique to make personalized reduction external fixator. Methods A case of severe comminuted tibia and fibula fracture was selected in April 2015. The patient was male, aged 18 years, and 67 kg. tall with a body weight of 171 cm,. Combined with computer aided technique and 3-D printing technique, individualized external fixator was used to treat it, and the clinical effect was observed after operation. Results the stent installation time was about 10 min, without fluoroscopy, and the reduction was successful. After operation, the recovery of both lower limbs was equal length, the X ray film showed that the distal fold end was corrected by 37 掳, the extraversion angle was corrected by 4 掳, the tibial fracture end was well aligned, and the lower extremity force line was completely corrected, which was consistent with the model after software simulation reduction. There was no new fracture displacement after operation, the fracture healed after 3.5 months, and reached strong bone healing after 8 months, and the knee joint movement function was good. Conclusion the treatment of severe comminuted fracture of tibia and fibula with 3-D printing individualized external fixator has the advantages of convenient operation, high degree of individuation, good effect of reduction, firm fixation, and no need of X-ray fluoroscopy in the reduction of tibia and fibula.
