摘要

本研究通过有限元分析比较了股骨近端仿生钉（PFBN）和股骨近端抗旋转钉（PFNA）在治疗骨质疏松性股骨转子间骨折中的生物力学特性。在骨密度相似的情况下，PFBN 在最大股骨位移、内固定位移、股骨头和内固定部件的应力分布以及股骨颈内翻角方面均优于 PFNA。随着骨密度的降低，PFBN 相对于 PFNA 的生物力学优势更加明显。这一发现表明，PFBN 在治疗骨质疏松性股骨转子间骨折方面更具优势。

Finite element analysis of proximal femur bionic nail for treating intertrochanteric fractures in osteoporotic bone.

This study compared the biomechanical characteristics of proximal femur bionic nail (PFBN) and proximal femoral nail antirotation (PFNA) in treating osteoporotic femoral intertrochanteric fractures using finite element analysis. Under similar bone density, the PFBN outperforms the PFNA in maximum femoral displacement, internal fixation displacement, stress distribution in the femoral head and internal fixation components, and femoral neck varus angle. As the bone density decreases, the PFBN's biomechanical advantages over PFNA become more pronounced. This finding suggests that the PFBN is superior for treating osteoporotic intertrochanteric femoral fractures.
