Evaluation of Porous Biphasic Calcium Phosphate Ceramics for Anterior Cervical Interbody Fusion in a Caprine Model

Abstract

Thirty percent, 50%, and 70% porous ceramics performed equal to or better than autogenous bone after 3 and 6 months. There may be promise for the use of 50/50 hydroxyapatite/beta-tricalcium phosphate in spine surgery as the need to harvest autograft from the iliac crest is obviated, and complications and cost associated with the harvest are avoided.
