ABSTRACT

We report a long-term study of bioactive bone cement (BABC) in a canine total hip arthroplasty (THA) at follow-up of 8 years. Previous studies have shown excellent biomechanical and histological results at follow-up of 6, 12, and 24 months. In the present study, THA was performed in a beagle dog using BABC consisting of an apatite- and wollastonite-containing glass ceramic (AW-GC) powder and SiO₂ powder as the filler and a bisphenol-a-glycidyl methacrylate (Bis-GMA) based resin as the organic matrix. Histological examination showed direct bonding between BABC and bone without any intervening soft tissue layer at the BABC-bone interface. A reactive layer, through which BABC bonded to the bone, was observed thicker at 8 years than it was at 24 weeks. No adverse effects of BABC were observed. BABC maintained the high bioactivity and direct bonding to bone in a canine THA at follow-up of 8 years.
