有限元分析应用于全髋关节置换中的研究进展

Finite element analysis of total hip arthroplasty

全髋关节置换术是治疗多种髋关节疾病的一种有效方式,多项研究发现术后假体的稳定性及多种并发症的发生均与关节周围生物力学因素有关,但髋关节复杂的解剖结构使得在体内和实验室对其进行生物力学研究非常困难。有限元分析对复杂物体的生物力学性能分析具有独特的优势,现已被成功应用于人体骨骼、关节和肌肉的相关研究,在骨科生物力学领域占有重要的地位。本文对近几年来有限元分析应用于全髋关节置换中的相关研究进行了较详细的总结,归纳了目前最新的研究进展及存在的问题,为以后的研究指明了方向。

Total hip arthreplasty is an effective method to cure varied diseases of hip joint ,many studies have found that the stability of prosthesis and multiple complications following total hip arthroplasty were associated with the biomechanical proper- ties of the prosthesis and bones. Due to the complex structure of the hip, it is very difficult to conduct the biomechanieal research in vivo or in laboratory. Finite element analysis has unique advantages in terms of biomechanical analysis of complex objects ,it has been applied to the biomechanical studies of human bones ,joints and muscles and plays an important role in orthopedic bio- mechanics. In this paper,we summed up the finite element analysis of total hip arthroplasty in recent years and summarized the latest research progress and problems,it indicates the direction for subsequent research.
