Wear Analysis of Hip Joint Prosthesis: A Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 2
Abstract
Total hip replacement (THR) is one of the most successful applications of biomaterials in the medical industry. In THR, a spherical head connected to the femoral stem articulates against a spherical cup/liner attached to the pelvic bone. The tribological performance of artificial hip joints is a critical issue for their success, because adverse tissue reaction to wear debris causes loosening and failure. The wear of the bearing surfaces of hip joint prostheses is a key problem causing their primary failure. Many studies on wear of hip prostheses have been published in the last 10 years. Theoretical/ numerical models have been proposed for investigating geometrical and material parameters also. This detailed study of wear analysis of hip joint is carried out highlighting anatomy of hip joint, wear and artificial implants such as hard on hard and hard on soft implants for hip joint. It aims to obtain in depth understanding of wear of bearing couples of artificial hip joint due to varying contact stresses under physiological gait loading.
