Abstract
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.
