Repairing Segmental Defect with a Composite Associating Collagen Membrane and MBCP® Combined with Total Bone Marrow Graft in Irradiated Bone Defect: an Experimental Study in Rabbit

Abstract:

Article Preview

The aim of this study was to study bone marrow quality from various location and species for reconstruction of segmental critical size defect in irradiated weigh bearing bone. Sample of bone marrow aspirates from rabbits and Beagle dog were analyzed. Rabbits were implanted with a composite associating resorbable collagen membrane plus micro macroporous biphasic calcium phosphate (MBCP®) and autologous bone marrow (BM) injected after irradiation. Bone marrow samples were found to be significantly less rich in tibia than in humerus and ilium in Dog and less rich in Dog than in Rabbit (p<0,05). Successful osseous colonization bridging of the defect were obtain at 16 weeks in all animals. Identical repartition of bone ingrowth and residual ceramic at the different levels of the implant suggest an osteoinduction role of the bone marrow graft in the center of the defect. This model succeeded in reconstruct a large segmental defect in weight bearing and irradiated bone in rabbit.
