Abstract
1. Phlebography has been done on seven hips showing no radiological evidence of osteoarthritis. The findings largely confirm the work of previous authors.
2. Thirty-seven osteoarthritic hips have been examined in the same way. As the degenerative process worsens radiologically so the pattern of venous drainage deviates further from the so-called normal.
3. An attempt is made to explain the phlebographic findings in the light of known facts of the pathology of the disease.
