Abstract

This study evaluated cervical disc replacements of porous bioresorbable hydroxylapatite (HA) and porous surfaced solid non-bioresorbable HA, for canine cervical disc fusions. The objectives were the promotion of interbody fusion, applicability and tissue response to disc replacement and appropriateness of the HA material design. The frequency of implant fracture and anterior extrusion suggests that the implant design was not suitable for the canine model. A major contributory factor is believed to be the inherent mechanical properties of the present hydroxylapatite discs. However, both types of disc replacements elicited a favorable tissue response and encouraged bone deposition at early time periods, with eventual fusion at later periods.
