[The importance of magnification angiography as an investigation for the arterial supply of the femoral head after medial neck fracture (author's transl)].

In observing the development in 20 patients who had been operated upon for fracture of the neck of the femur a significant interrelation between the angiographic result and the formation of a necrosis of the head of the femur has been ascertained. The magnification angiography enables the terminal arterial region of the femoral vessels to be assessed with a still higher degree of certainty and thus appears to be a valuable diagnostic measure for the prognostic assessment of the medial fracture of the femoral neck.
