title: Effect of the high femoral osteotomy upon the vascularity and blood supply of the hip joint.
abstract: This investigation was done to study the effects of high femoral osteotomy upon the vascularity and blood supply of the hip and to further our knowledge of its physiologic basis. We have used established methods of study, including bone scans, microangiography, isotope clearance and perosseous venography, and based upon the results of these studies, we have reached certain conclusions. First, high femoral osteotomy increases the blood flow and vascularity in the hip joint, the femoral head and neck and the great trochanter. Second, bone scanning techniques using 99mTc labeled diphosphonate have shown increased uptake in the femoral head and neck after high femoral osteotomy. The localization was done using a Digital Gamma III computer, and the activity on the osteotomy side at two weeks was 3.5 times as great as on the control side. By 16 weeks postoperatively, there was still two times as much activity on the osteotomy side. Third, microangiography showed increased vascularity both at the osteotomy site and in the femoral head and neck and the greater trochanter on that side. Such an increase in vascularity first became evident two weeks after osteotomy and persisted during the four month period studied. Fourth, the results of the 99mTc diphosphonate clearance study showed a 25 per cent increase in femoral head blood flow on the operative side. Fifth, perosseous venography of the femoral head and neck showed a marked increase in venous drainage through the osteotomy site in the immediate postosteotomy stage.
