We have investigated the intraosseous partial pressures in 15 patients suffering from primary arthrosis of the hip. The measurements were performed by a mass spectrometer via a specially designed inlet system. The average pO2 and pCO2 values in the femoral head were 8.2 and 6.8 kPa (62 and 52 mmHg), respectively, and in the greater trochanter 6.6 and 5.1 kPa (51 and 39 mmHg). The average intraosseous pressures in the femoral head and greater trochanter were 5.5 and 3.0 kPa (42 and 23 mmHg). The differences between the intraosseous pressures, pO2 and pCO2 in the greater trochanter and the femoral head were all significant.
我们对15例原发性髋关节骨关节炎患者的骨内分压进行了研究。测量是通过一台质谱仪，经由一个专门设计的进样系统进行的。股骨头内的平均pO₂和pCO₂值分别为8.2和6.8kPa（62和52mmHg），大转子处则分别为6.6和5.1kPa（51和39mmHg）。股骨头和大转子处的平均骨内压分别为5.5和3.0kPa（42和23mmHg）。大转子与股骨头之间的骨内压、pO₂和pCO₂差异均具有显著性。
