  • Primerjava obrabnih delcev polietilena in poliacetala, izoliranih iz tkiva ob izoelastičnih kolčnih protezah = Comparison of polyacetal and polyethylene wear particles isolated from periprosthetic tissues of isoelastic prostheses
    Kocijan, Aleksandra ; Milošev, Ingrid
    Isoelastic prostheses are a special type of total hip replacement consisting of two polymer materials: polyacetal stam and polyethylene acetabulum cup. Dueto relatively poor clinical results their ... implantation has been restricted during the last decade. In order to reveal the reasons for their unsuccessful clinical performance, we examined the prosthetic components and periprosthetictissue of failed prostheses. A method of tissue digestion using sodium hydroxide followed by centrifugation of the digested tissues was used to separate polyacetal and polyethylene particles. Polyacetal particles were verified by energy-dispersive X-ray spectroscopy (EDS) and polyethylene particles were identified by fourier-transform IR (FTIR) spectroscopy. Scanning electron microscopy (SEM) confirmed that the majority of particles were micrometer in size and their morphology was fibril-like or shred-like.
