The Failure of Polyvinyl Sponge as a Bone Substitute

Abstract

SUMMARY Two experiments were carried out using polyvinyl alcohol sponge (Ivalon) to fill complete defects in the shafts of canine femora. These experiments show that this plastic is: Tolerated by skeletal tissues without any evidence of foreign body reaction. Infiltrated at 3 months by vascular fibrous tissue showing no evidence of calcification or osteoid tissue. Not the complete answer as a substitute for bone.
