CopiOs(TM) Bone Void Filler in the Post-Harvest Iliac Crest

Purpose of the study is to evaluate the in-vivo use of CopiOs bone void filler in a single site trial, providing pre and post-operative evaluations of subjects undergoing spinal fusion with autogenous bone graft, in whom the CopiOs has been used as a bone void filler in the post-harvest iliac crest.
