[Histomorphology of the bone-cement contact. Experimental phenomenology of the osseous reconstruction processes. I].
In animal experiments the femurs of 25 rabbits were filled with bone cement. In cross sections of the diaphysis even after only one week, small gaps were found filled by lamellar formation of new bone. Osteoblast layers directly on the cement surface were also observed. After 4 to 6 weeks there was a circularly closed contact of inner lamellae and after 9 months a secondary medullary cavity was formed. At this time there was formed a trabcular contact with the implant, interrupted by medullary spaces full of cells. Sometimes woven-bone formations were found in the bone-cement interface.
