In 6 mongrel dogs (eleven hips) the intraosseous pressure was measured in the femoral head as well as acetabulum in various hip joint positions. The control position for the measurements was 90 degrees flexion in which the pressures were found low and stable. The intraosseous pressure in both locations were subjected to consistent pronounced variations when the joint position was altered. In the femoral head, significant pressure increases (p less than or equal to 0.01) were found in maximal extension, maximal flexion, maximal adduction, 90 degrees external rotation, 45 degrees internal rotation, and maximal internal rotation. The pressure in acetabulum rose significantly in maximum flexion, 45 degrees internal rotation, and maximum internal rotation, whereas the pressure increase in maximal extension and maximum adduction was consistent but not significant. The pressure increase is most probably caused by inhibition of the venous drainage changing the bone hemodynamics in the juxta-articular bones. A complete obstruction of venous drainage was not observed since the intraosseous pressure in none of the measurements reached the level of the arterial pressure.
在6只杂种狗（11个髋关节）中，测量了不同髋关节位置时股骨头和髋臼内的骨内压。测量的对照位置为90度屈曲，此时压力较低且稳定。当关节位置改变时，两个部位的骨内压均出现持续明显变化。在股骨头，最大伸展、最大屈曲、最大内收、90度外旋、45度内旋和最大内旋时骨内压显著升高（p≤0.01）。髋臼内压在最大屈曲、45度内旋和最大内旋时显著升高，而最大伸展和最大内收时压力升高但不显著。压力升高很可能是由于静脉引流受阻改变了关节周围骨的骨血流动力学所致。由于所有测量中的骨内压均未达到动脉压水平，因此未观察到静脉引流完全阻塞。
