[Bone perfusion after plate osteosynthesis. A study of the intact rabbit tibia with disulfin blue vital staining].

After operative fracture treatment an interference with blood supply has to be expected. The fixation of a plate to an intact rabbit tibia lead to extended areas where circulation is disturbed. These disturbances were partially reversible within one week without structural changes visible in the recovering bone. Only the zones remaining without vascular supply after one week started to recover in the 4th week, when intracanalicular remodelling and the formation of new Haversian systems became visible at the borders of the avascular regions.
