A survey of degenerative arterial change in the capsule of the hip joint in different disease states.

Degenerative arterial disease does affect the ligamentum teres and the capsule of the hip joint. In this investigation, the frequency of these changes was investigated in four groups of patients with hip disease. It is concluded that the highest incidence of all of degenerative arterial disease is found in elderly patients with subcapital fractures and in young patients with avascular necrosis of the femoral head after renal transplantation. The significance of this finding needs to be investigated further.
