Resumen (ES)
An experimental study was carried out to demonstrate
the utility of costal, fresh or cryopreserved cartilage
(autologous and homologous), in the treatment of cavitary
bone defects of long bones and to observe whether simple
radiology is reliable for assessing of its incorporation. The
study involved implanting costal cartilage, without perichondrial
tissue, in a cavitary bone defect of the distal metafisis in
rabbit femur. Two types of graft were used, according to their
origin (autologous and homologous) and to the conservation
procedure (fresh and cryopreserved). We worked on 3 separate
groups of 6 rabbits. We assessed the incorporation of the
graft by means of histology and simple radiology studies, at 3,
6 and 12 weeks. The conclusions of this work demonstrate
that costal cartilage implants do not act as osteoinductor elements,
and that simple radiology is not a reliable method for
assessing the incorporation of the graft.
