Possibility of intrachondral ossification since a bony matrix with Titanium

Abstract

In the present study, the relation between bone, cartilage and titanium was analyzed. According to the established methodology, homogeneous cartilage grafts conserved in alcohol 100 GL for 7 days were used, after the fixation of a homologous cartilage graft above the bone cortical of a rat femur (Rattus novergicus var. Albinus rodentia mammalia cepa Wistar), using a titanium screw implant. The animals were sacrificed at 10, 20, 30 and 60 days after surgery. To the histological examination, in hematoxillin and eosin sections, intrachondral bone neoformation could be observed since cortical surface, with possibility of complete substitution of the cartilage graft by bone, with similar volume and shape. In this experimental study we concluded that the homogeneous cartilage conserved can be used as graft not only for tissue substitution but also as an inductor of bone growth in rats.
