[Revascularization of avascular spongy bone].
There have been studied the state of blood circulation in proximal parts of femur of 24 dogs (48 hip joints with simulated aseptic necrosis). In the first group of joints there have been carried out revascularization of the head by caudal epigastric artery with commitant veins. The second group have been subjected to tunneling. The third group of joints served as a control. Microcirculation disturbances, ascertained by intraosseous contrast phlebography arteriography and microscopic examination of osseous tissue, indicated that aseptic necrosis of the head of femur in an experiment is accompanied by increased intraosseous pressure, revascularization of an avascular spongy bone causes stable normalization of intraosseous hemodynamics.
