We followed the natural course of osteoarthritis of the hip radiographically in 17 patients (20 hips) for an average term of 11 years.
And we measured the Sharp angle, CE angle, slope of acetabular roof, acetabular head index, head lateralization index, and the flattening of femoral head at first consultation.
Roof osteophytes were found on the hips of six patients at the last consultation, in which the head lateralization index tended to be higher. It was concluded that predicting a course of roof osteophyte formation was difficult.
