question 71

Essay

Johnny fractured the lower third of his right tibia in a skiing accident. The soft tissues in the area were severely damaged and their surgical removal was necessary. After prolonged immobilization, it was found that Johnny was healing very poorly. The explanation offered by the orthopedic surgeon was that vascularization of the fracture site was still inadequate and good healing was absolutely dependent upon an adequate blood supply. Describe how a long bone receives its blood supply and trace the path of nutrient delivery to the osteocytes.
