Abstract
The osteolytic response to ultrahigh molecular weight polyethylene (UHMWPE) has been linked to the failure of total joint replacements. A classification system based on a set of standard numerical shape descriptors that quantify the size, shape and texture of individual particles is presented. Analyses is performed on a sample of 50 particle images. From this sample, three distinct particle types was identified: type 1 particles made up to 70% of the sample and had AR<2.5 and C>0.6; type 1a particles had FD<1.05 and accounted for 60% of the type 1 particles and type 1b particles had FD>1.05; type 2 particles accounted for 20% of the sample and had AR>4.0. The remaining 10% of the sample did not fit cleanly into a new type classification.
