ABSTRACT

Purpose: to study the healing process of a defect of the compact bone tissue after the implantation of osteoplastic material «easygraft CRYSTAL¼. Methods: the experiment was conducted on 24 Wistar rats. In the middle third of the diaphysis of the femur we created a perforated defect of 2.5 mm diameter in the medullary canal, which was filled with osteoplastic material «easy-graft CRYSTAL¼. Fragments of the injured bones were studied on the 60th and 120th days by light microscopy with morphometry and scanning electron microscopy. Results: it was found that in the area of the defect of the compact bone tissue «easy-graft CRYSTAL¼ shows high biocompatibility, osteoconductive properties and provides stability to the volume of the defect due to good integration with the bone tissue of regenerate and absence of signs of resorption of osteoplastic material throughout the period of experiment.

Objetivo: estudiar el proceso de reparación de un defecto del tejido óseo compacto después de la implantación de material osteoplástico (easy-graft CRYSTAL). Métodos: el experimento se realizó en 24 ratas Wistar. Se realizó en el tercio medio de la diáfisis del fémur un defecto de 2,5 mm de diámetro en el canal medular que se rellenó de material de osteoplástico (easy-graft CRYSTAL). Los huesos lesionados fueron estudiados en los días 60ª y 120ª mediante microscopía óptica y microscopía electrónica de barrido. Resultados: se encontró que en la zona del defecto del tejido óseo compacto el injerto mostró alta biocompatibilidad y propiedades osteoconductivas y proporcionó estabilidad al volumen del defecto debido a la buena integración con el tejido óseo y ausencia de signos de resorción de material osteoplástico durante todo el período experimental.
