The authors tested the osteoinductivo capacity of powdered heterologous (bovine) damlnerailied bone matrix in rets. The first pert of the study concerned a mono lateral posterior spinal Implant after dKorticatron ul three vertabrae, using as a control area the animal's contralateral sidB, in which neither bDno graft nor any other malarial were placed. In another group of rats, a comparative evaluation was made of powdered hetorologous demineralizad bone matrix and fresh autologous bone. In the same animal, autologous bone was implanted to realize a thoracic posterior fusion and demlnarallzed bora matrix, to Induce a posterior fusion in tin a:umbar area. Alt data obtained suggested a good ostcoinductive activity of hetarologous powdered demineralized bone matrix. The two posterior spinal fusions done in the same animal with heterologous dsmineralizad bone matrix or autologous bone, respectively, had similar callus development and required the same time for formation.
