Eight patients with osteoarthritis of the hip, rest pain and intraosseous hypertension of the proximal femur obtained ameliorated rest pain and reduced intraosseous hypertension 3 months after a fenestration operation in the region of the greater trochanter. They were investigated with intraosseous phlebography of the proximal femur. Six patients showed delayed intraosseous drainage and 7 had altered patterns of drainage before the operation. Three months after the operation the phlebograms showed an even more prolonged drainage time. However, this difference was not of a statistically significant magnitude. Drainage patterns remained mainly unchanged.
8例髋关节骨关节炎、静息痛及股骨近端骨内高压患者，在大转子区域行开窗手术后3个月，静息痛得到改善，骨内高压降低。对他们进行了股骨近端骨内静脉造影检查。6例患者术前骨内引流延迟，7例引流模式改变。术后3个月静脉造影显示引流时间进一步延长。然而，这种差异在统计学上不具有显著意义。引流模式基本保持不变。
