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.
在本研究中，我们旨在创建并验证一个有限元（FE）模型，以估计骨水泥注入后的骨温，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，在注入后约12分钟，骨表面测得的最大温度升高为10°C。实验期间测得的温度曲线与模拟曲线相符，平均误差为1.73°C。尽管需要进一步的实验来进一步验证该模型，但本研究结果表明，该模型是用于骨增强规划以降低热坏死风险的一个有前景的工具。
