Orthopaedics polymeric implants made of ultra-high molecular-weight polyethylene (UHMWPE), polyether-ether-ketone (PEEK) or its carbon-fiber reinforced composite (CFR-PEEK) can be coated with titanium (Ti) or hydroxyapatite (HA) by compression- moulding or plasma-spray techniques for bone integration. The coating may also improve the radiological properties of the implanted device. This work aimed at developing a tissue-equivalent phantom for measuring the radiological contrast given by different polymeric materials coated with Ti or HA for orthopedic implant applications.

Abstract
Orthopaedics polymeric implants made of ultra-high molecular-weight polyethylene (UHMWPE), polyether-ether-ketone (PEEK) or its carbon-fiber reinforced composite (CFR-PEEK) can be coated with titanium (Ti) or hydroxyapatite (HA) by compression- moulding or plasma-spray techniques for bone integration. The coating may also improve the radiological properties of the implanted device. This work aimed at developing a tissue-equivalent phantom for measuring the radiological contrast given by different polymeric materials coated with Ti or HA for orthopedic implant applications.File in questo prodotto:
