[Revascularization of hypertrophic pseudoarthroses after pressure-plate osteosynthesis].

In 6 adult mongrel dogs hypertrophic pseudarthroses in the radius were produced. The pseudarthroses were stabilized by compression plate osteosynthesis. The changes in the pattern of vascularization in pseudarthroses under stabilization were studied by means of microangiography. The interfragmental gap revascularization started early and came from medullary vessels of both fragments. Vessel anastomoses in interfragmental areas were observed. With time, medullary and periosteal hypervascularization were reduced. However, the hypervascularization in the remodeled corticalis was still evident after 3 months.

[Revascularization of devitalized cortical segments under stabilizing encircling wires].

In 10 adult mongrel dogs isolated cortical fragments of the diaphysis of the radius were reimplanted and stabilized by encircling wires. The changes in the pattern of vascularization and the revitalization of the avascular fragment were investigated by microangiography. The revascularization arose from the medullary vessels that penetrated the avascular fragment. The fracture gap was bridged by intracortical anastomoses. After 6 weeks fracture healing was noted and the vessels showed a restoration of the physiologic pattern of vascularization.
