Abstract

The applicability of a polyether ether ketone locking compression plate (PEEK LCP) fabricated using FDM (fused deposition modeling)-based 3D printing to treat actual patients was studied. Three different tests-bending, axial compression, and axial torsion-were conducted on tibial non-osteoporotic comminuted diaphyseal fracture samples fixed with the commercial titanium alloy LCP and 3D-printed PEEK LCP. Comparing the outcomes of these tests revealed that the commercial titanium alloy LCP underwent plastic deformation in the bending and axial torsion tests, though the LCP did not fail even when an external force greater than the maximum allowable load of the tibia fixture of the LCP was applied. Elastic deformation occurred in the 3D-printed PEEK LCP in the bending and axial torsion tests. However, deformation occurred even under a small external force, and its stiffness was 10% compared to commercial titanium alloy LCP. Thus, 3D-printed PEEK LCP can be applied to the fracture conditions in non-weight-bearing regions. The experimental results reveal detailed insights into the treatment of actual patients by considering the stiffness and high toughness of 3D-printed PEEK LCP.

摘要

研究了使用基于熔融沉积建模（FDM）的3D打印制造的聚醚醚酮锁定加压钢板（PEEK LCP）治疗实际患者的适用性。对用商用钛合金LCP和3D打印的PEEK LCP固定的胫骨非骨质疏松性粉碎性骨干骨折样本进行了三种不同的测试——弯曲、轴向压缩和轴向扭转。比较这些测试的结果发现，商用钛合金LCP在弯曲和轴向扭转测试中发生了塑性变形，尽管即使施加大于LCP胫骨固定装置最大允许载荷的外力，LCP也没有失效。3D打印的PEEK LCP在弯曲和轴向扭转测试中发生了弹性变形。然而，即使在小外力作用下也会发生变形，其刚度与商用钛合金LCP相比为10%。因此，3D打印的PEEK LCP可应用于非负重区域的骨折情况。实验结果通过考虑3D打印的PEEK LCP的刚度和高韧性，揭示了对实际患者治疗的详细见解。
