Finite Element Analysis of Artificial Hip Joint Movement During Human Activities

Estimation of appropriate lubricating film thickness in ceramic-on-ceramic hip prostheses

“…2 shows the effect of the load on the predicted minimum film thickness. The femoral head radius of 13 mm is assumed for the analysis based on the geometry model of the unipolar artificial hip joint proposed by Ekoet al [14].It is clearlynoticed that an increase in the load leads to a decrease in the predicted film thickness. This is as expected because the lubricant cannot withstand a significant load.…”

Finite element study of contact pressure distribution on inner and outer liner in the bipolar hip prosthesis

“…In addition, the excessive or inordinate human activities can induce the higher RoM and cause the impingement. Researches of impingement caused by human daily activity using finite element analysis have been performed [4][5][6]. Further,the researcheshave beendevelopedinto the more spesific Salat activity [7][8].…”

Finite element analysis of the impingement on the acetabular liner rim due to wear of the acetabular liner surface

“…In general, the early and late dislocations are mostly related to the impingement between the neck stem with the acetabular liner rim and to wear of the acetabular liner surface, respectively [1][2]. Study of the impingement on the RAL in this paper is initiated by several previous studies related to hip dislocation due to human activities [3][4][5].…”
