This study aims to evaluate the mechanical performance of custom 3D-printed titanium plates in the treatment of distal humerus fractures. Rigidity of four plating configurations were investigated by finite element analysis. The results reveal that implementation of custom designs with minimal screw holes, lateral-medial linking screw and lateral brim could significantly improve stiffness and consequently leads to better biomechanical stability as compared to standard osteosynthesis design. Biomechanical testing was also performed to validate practical usability. The results confirm that newly designed custom plates fabricated by selective laser melting is a possible alternative for the treatment of distal humerus fracture.
本研究旨在评估定制 3D 打印钛板在治疗肱骨远端骨折中的机械性能。通过有限元分析研究了四种接骨板固定方式的刚性。结果表明,与标准接骨术设计相比,采用最小化螺钉孔、内外侧连接螺钉和外侧边缘的定制设计可以显著提高刚性,从而获得更好的生物力学稳定性。还进行了生物力学测试以验证实际可用性。结果证实,通过选择性激光熔化制造的新型定制接骨板是治疗肱骨远端骨折的一种可行选择。
