Studies on Intraosseous Pressure (1st Report)

Abstract

Bone blood circulation was studied by measuring intraosseous pressure experimentally and clinically.
The following results were obtained.
1. Intraosseous pressure was determined by correlations between the rate of inflow and outflow.
2. The range of the variations of individual intraosseous pressure was very wide, and there were no correlations between carotid artery pressure and intraosseous pressure.
3. In some diseases of the hip, intraosseous pressure in the femoral head was consistently higher than that in the femoral neck.
4. In intraosseous pressure in necrotic area of the femoral head of the adults, pulsative waves were not found, but in the head of Perthes disease pulsative waves were always observed.
