The authors studied in the dog, using radioactive microspheres, the blood bone outputs of the trochanter, the femoral diaphysis and the tibial diaphysis, and measured, in a simultaneous fashion, the intra-medullar pressures in these bone regions. A same hierarchy of outputs is consistently found in all animals : the trochentarian outputs are always the highest, and next come, in decreasing order, the outputs of the femoral diaphyses and the tibias. On the other hand, the intra-medullar pressures, although differing according to the bone regions, always have rather superposable rates, so that the neighboring intra-medullar pressures always correspond to radically different outputs. It is thereby demonstrated that the intra-medullar pressures, as an isolated parameter, cannot accurately reflect the rate of bone output.
