The importance of the angle of anteversion in the development of arthritis of the hip.

Abstract

The angle of anteversion, assessed by the Dunlap technique, was determined in 30 patients suffering from primary osteoarthritis of the hip. This was compared with the same angle in 10 normal subjects. The patients with arthritis showed a statistically significant increase in the angle. This is considered by the authors to play a significant part in the pathogenesis of primary osteoarthritis of the hip.
