本研究的目的是研究有限接触动力加压钢板（LC-DCP）长度和螺钉数量及位置对胫骨中段骨折的生物力学影响，并为微创钢板接骨术（MIPO）提供生物力学证据。对于生物力学测试，使用60个来自尸体（死亡年龄，20-40岁）的胫骨来创建无缺损的中间和对角骨折模型。胫骨随机分组，并进行生物力学和三维（3D）有限元分析。检查了不同长度（6、10和14孔）的LC-DCP与6枚螺钉、14孔LC-DCP与不同数量（6、10和14）的螺钉以及14孔LC-DCP与6枚螺钉在不同位置的力学特性（包括压缩、扭转和弯曲）之间的差异。与10孔和14孔LC-DCP相比，6孔LC-DCP具有更大的垂直压缩应变（P
The aim of the present study was to investigate the biomechanical effects of varying the length of a limited contact-dynamic compression plate (LC-DCP) and the number and position of screws on middle tibial fractures, and to provide biomechanical evidence regarding minimally invasive plate osteosynthesis (MIPO). For biomechanical testing, 60 tibias from cadavers (age at mortality, 20-40 years) were used to create middle and diagonal fracture models without defects. Tibias were randomly grouped and analyzed by biomechanic and three-dimensional (3D) finite element analysis. The differences among LC-DCPs of different lengths (6-, 10- and 14-hole) with 6 screws, 14-hole LC-DCPs with different numbers of screws (6, 10 and 14), and 14-hole LC-DCPs with 6 screws at different positions with regard to mechanical characteristics, including compressing, torsion and bending, were examined. The 6-hole LC-DCP had greater vertical compression strain compared with the 10- and 14-hole LC-DCPs (P
