Analogue femurs for laboratory investigations of prosthesis stress distributions and fixation failures.
A polymeric analogue femur in combination with a brittle-coating stress-analysis technique was used to compare the relative femoral surface-strain distributions for various hip prostheses. The influence of prosthesis design factors, such as the geometry and material, the effect of a collar, and surface texturing, were readily ascertained and in agreement with previous investigations using other techniques. The fixation failures observed with this laboratory test model were similar to those of published clinical findings.
