[Angiographic demonstration of the medullary space and callus vessels during secondary bone fracture healing; animal experiments].
The artery nutritia ruptured in a closed transverse fracture of the tibia in 86% during the fracture trauma. Because blood vessels go through between the periost and the metaphysial medullary space it does not come to an ischemia in the medullary space of the distal fragment. The periosteal and paraosseous revascularisation increased with the extension of the fragment shifting. The artery nutritia is recombinated spontaneously in the complete cross section after 10 weeks. A good demonstration of the callus vessels is attainable by lumbar aortography with barium sulphate.
