Abstract
Cement anchor pegs have been used in acetabular cup fixation. This paper analysed various designs of cement anchor pegs using the finite element method. The design parameters have been investigated including the diameter, length, position and chamfer of the cement anchor pegs. It was found that introducing a chamfer to the cement anchor pegs would reduce the maximum stress by 25 percent in the cement mentle. The analysis in this paper provides the foundations further work to be carried out including a detailed model of bone and cement interfaces.
