个体化3D打印模型在骨科术前模拟中的应用

Application of individualized 3D printing model in orthopedic preoperative simulation

目的探讨个体化3D打印模型应用于骨科术前模拟的优势。方法将320例我院骨科手术患者分为3D打印组和普通影像组应用于实验,对两组患者的手术用时、术中出血量、术后功能评分变化、术后康复时间以及内植物选择的合理性于术后12个月进行全面评估。结果3D打印组与普通影像组进行对比:手术平均时间明显缩短(t=2.86,P<0.01);术中出血量明显减少(t=3.19,P<0.01);围手术期在使用相同康复方法的前提下,康复时间平均缩短3.2 d,,术后功能评分变化无明显差异;内植物选择更加准确可靠,节约术前准备时间及手术预算。结论个体化3D打印模型与传统术前准备(普通影像学资料)相比,前者应用于骨科术前模拟具有显著优势。

Objective To explore the advantages of utilizing individualized 3 D printing model in orthopedic preoperative simulation. Methods Three hundred and twenty patients with orthopedic surgery in our hospital were divided into 3 D printing group and normal imaging group. The operation time, intraoperative blood loss, postoperative functional score change, postoperative recovery time and internal plant selection were compared between the two groups. Rationality was fully evaluated at 12 months postoperatively. Results The patients in 3 D printing model group had shorter operation(t=2.86,P<0.01) and smaller bleeding amount(t=3.19, P<0.01). In addition, their recovery duration was also shortened by 3.2 days under the condition of receiving the same treatment. There was no significant difference in postoperative functional scores;Furthermore, the selection of internal plants was more accurate and reliable, saving preoperative preparation time and operating budget. Conclusion Compared with traditional preoperative preparation(general imaging data), the individualized 3 D printing model has significant advantages in preoperative simulation of orthopedics.
