Quote from company website
DEPUY introduces the PINNACLE Acetabular Cup System with patented Variable Interface Prosthesis (VIP) taper technology. The PINNACLE Acetabular Cup is designed to accommodate multiple advanced bearing materials and provide surgical options without compromise. Surgeons now have a choice between standard polyethylene, MARATHON Cross-linked Polyethylene and ULTAMET metal inserts, which all work within one acetabular shell.
