Studies on bisphosphonate elution from orthopaedic implants

Roberts, Jacintha. January 2008 (has links)
In a 6-week rat model it was demonstrated that a small dose of peri-implant zoledronic acid (ZA) increased local bone formation 3-fold compared with controls. Ancillary in vitro studies using 14C-labeled ZA implant doses demonstrated biphasic elution profiles for implants coated with hydroxyapatite; complete ZA release occurred within one to three weeks in serum compared with only 60% ZA release after 12 weeks in water. Implants without hydroxyapatite coating showed more burst-type release profiles and full ZA elution within 24 hours of hydration in serum or water. Canine studies at 6 weeks using implants with 14C-labeled ZA showed that the compound remained localized, with the greatest ZA concentration immediately adjacent to the implant. Although there was evidence of skeletal ZA distribution via diffusion into the circulation, the levels were two orders of magnitude less than at the implant site.
