Vascular pattern of the developing proximal femur in the domestic fowl
Abstract:
The vascular pattern of the proximal femur and its importance in the aetiology of coxofemoral conditions has been established in many species, including man. In the avian femur, vascular lesions have been associated with pathological conditions. Ninety-six laying strain chicks were reared from day-old until 20 weeks. Birds were killed throughout the growth period and specimens were prepared for study. The origin and nature of epiphyseal vascular canals was established. Three principal stages of development occurred, namely growth plate formation, the growth period and the cessation of growth. Transphyseal vessels are described in the day-old chick to which a nutritive function is ascribed. Anastomosis did not occur between epiphyseal vascular canals. The epiphyseal vascular canals are grouped according to their source.
