摘要

在本研究中，我们旨在建立并验证一个有限元(FE)模型来估计骨水泥注射后的骨温度，并将模拟温度结果与股骨近端三个关键位置的实验数据进行比较。模拟结果表明，注射后约12分钟，骨表面测得的最高温升为10℃。实验过程中测量的温度曲线与模拟结果一致，平均误差为1.73°C，虽然还需要进一步的实验来验证模型，但本研究的结果表明，该模型是一种很有前途的工具，用于骨增强计划，以降低热坏死的风险。

A BIOMECHANICAL AND THERMAL ANALYSIS FOR BONE AUGMENTATION OF THE PROXIMAL FEMUR.

In this study, we aim to create and validate a Finite Element (FE) model to estimate the bone temperature after cement injection and compare the simulation temperature results with experimental data in three key locations of the proximal femur. Simulation results suggest that the maximum temperature-rise measured at the bone surface is 10°C which occurs about 12 minutes after the injection. Temperature profiles measured during the experiment showed an agreement with those of the simulation with an average error of 1.73°C Although additional experiments are required to further validate the model, results of this study suggest that this model is a promising tool for bone augmentation planning to lower the risk of thermal necrosis.
