The Use of Radioactive Phosphorus in High Fractures of the Femoral Neck

Abstract

The use of radioactive phosphorus ("P) in determining the vascularity of the femoral head and there ore treatment for high fractures of the femoral neck is reported in 89 cases. The t e c h k p e is described and results analysed. Autoradiograms of the femoral head are used to check the initial assessment of vascularity.

Devitalization of the Femoral Head After Medial Fracture of the Femoral Neck

“…The blood supply to the femoral head via the cancellous bone is always affected by the fracture itself; in severely displaced fractures damage to the epiphyseal arteries in the joint capsule further reduces the circulation in the femoral head. The blood vessels of the ligamentum teres are of minor importance in the nutrition of the femoral head (Sevitt & Assessment of the viability of the femoral head after medial fracture of the femoral neck is clinically difficult (Hulth 1965 Boyd et al 1955, Eegholm 1970, McNeur 1970. Interpretation of the results is difficult, however, and none of these methods has gained any wide clinical acceptance.…”
