Fibra de carbono como material de interposición en defectos del cartílago de crecimientoestudio experimental

Résumé

The problem set forth by the traumatisms of growth cartilage regarding the treatment of the osseus bridges and its sequelas has motivated the carrying out of an experimental model in rabbit. It has been our pretension to evaluate the utility of the carbon fibre as a material of insertion in the prevention of osseous bridges formation after a physeal distal femoral lesion surgically provoked. 24 rabbits, of both sexes, 4 weeks old and with an average weight of 1.200 g have been used for this experiment. These have been distributed into 4 group composed of 6 animals each, taking into account the moment of sacrifice, 1, 2, 4 and 8 weeks. Both femurs of each animals were operated on executing an external resection of the growth plate in distal extremity of the femur. The left femur was taken as control and was left to evolve. A carbon fibre was implanted on the right femur, taken as experimental. All the specimen were studied macroscopically, radiologically and histologically, observing that the carbon fibre used as material of interposition in the defects growth cartilage sets as a passive barrier retarding the appearance of the osseous bridges.
