Improvement of blood supply and structure of avascular spongy bone: experimental study
Model of avascular necrosis of the femoral head was induced bilaterally in the 52 hips (26 dogs). Immediately intertrochanteric osteotomy was done on 18 hips and 17 hips had autogenous muscle-pedicle bone graft. Seventeen were kept as controls. Intraosseous pressure was measured, the vascular architecture was studied, and histologic examination of the femoral heads was done at 4, 8, and 12 weeks. The authors consider that intertrochanteric osteotomy gives highly favorable effect on the structure of avascular femoral head and intravenous administration of nitroglycerin solution improves the intraosseous circulation.
