To prospectively evaluate the effect of a computed tomography (CT)-based three-dimensional (3D) printing surgical guide on surgical accuracy of tibial plateau leveling osteotomy (TPLO). Cadaveric study. Canine cadaveric hindlimbs ( = 14). TPLO was performed on cadaver hindlimbs disarticulated at the coxofemoral joint to compare and evaluate the conventional TPLO method ( = 7) with one that used customized 3D printing surgical guides ( = 7). The operation time and postoperative tibial plateau angle (TPA) of the osteotomy were evaluated. Moreover, the osteotomy inclination, torsion, and distance and the direction of eccentricity were assessed using CT reconstruction. Significant differences in the operation time ( < 0.001), postoperative TPA ( < 0.05), osteotomy inclination ( < 0.05), and osteotomy torsion ( < 0.05) were observed. The use of TPLO surgical guide reduced the operation time and inaccurate osteotomy. The surgical technique applied with a customized 3D printing surgical guide could be used to perform osteotomy and TPA adjustment more precisely than conventional TPLO.
前瞻性评估基于计算机断层扫描（CT）的三维（3D）打印手术导板对胫骨平台水平截骨术（TPLO）手术准确性的影响。尸体研究。犬类尸体后肢（n = 14）。对在髋关节处离断的尸体后肢进行TPLO，以比较和评估传统TPLO方法（n = 7）与使用定制3D打印手术导板的方法（n = 7）。评估截骨术的手术时间和术后胫骨平台角度（TPA）。此外，使用CT重建评估截骨术的倾斜度、扭转度、距离和偏心方向。观察到手术时间（P < 0.001）、术后TPA（P < 0.05）、截骨术倾斜度（P < 0.05）和截骨术扭转度（P < 0.05）存在显著差异。使用TPLO手术导板可减少手术时间和截骨术不准确情况。与传统TPLO相比，应用定制3D打印手术导板的手术技术可更精确地进行截骨术和TPA调整。
