Abstract

Computational methods used to quantify wear in failed hip arthroplasties are often limited by human and sampling errors. An automated software solution has been developed to overcome these shortcomings. The overarching aim of the current study was to validate this method through a comparison with gravimetric measurements. Seventy-two different wear volumes were quantified to within a mean error of 0.14 mm3 and 0.10 mm3 of gravimetric results for simulated cup and head components, respectively. This approach had an improved accuracy, repeatability and reproducibility over a commonly used, commercially available software solution, which bears many of the common sources of error.
