Vascularity of femoral head and its assessment after femoral neck fractures
Femoral neck fracture has an annual incidence of 1 per 1000 population; in young patients, functional prognosis is not good due to risk of osteonecrosis. Femoral head vascularity is mostly contributed by retinacular vessels and lateral epiphyseal artery. The vascular impact is due to displacement, i...
