  • Title: [Vascular regeneration of rabbit femoral bone marrow after curettage (author's transl)].
    Author: Sick H, Oberling F, Fricker JP.
    Journal: Arch Anat Histol Embryol; 1974; 57(2):229-46. PubMed ID: 4620137.
    Abstract:
    The curettage of a section of bone marrow in rabbit femur entails the destruction of the corresponding vascularization. Starting on the first day the undistroyed interadipocytic network is widely open. It is fed: 1. via those branches of the nutrient artery that stay connected; 2. via branches of the nutrient artery that become disconnected and then form anastomosis with the epiphysial arteries or compact bone arteries and thus become revascularized; 3. via the arteries vascularizing compact bone. By the thirds of fourth day after intervention, both poles of the hematoma are lined by vascular caps. This is composed of a rich network neo-vessels showing three distinct levels. After four or five weeks these networks will have come together and anastomosed. Between the hematoma and the compact bone tissue large vascular lacunae are formed. They receive blood from the arteries of the compact bone. The vascular networks drain into the veins of diaphyseal compact bone or are drained via intact vestiges of the central venous sinus. In those areas where the hematoma is reabsorbed, a partially reconstructed vascular tree appears. Peripheral longitudinal arteries send out centripetal rami towards the central vascular buds as well as centrifugal rami towards subcortical vascular buds. The interdipocytic network also regains its normal morphology. The central venous sinus extends from one epiphysis to the other and is usually drained into the veins of the trochanteric fossa proximally and into the popliteal veins and supra-trochlear veins distally.
