Abstract
We followed the natural course of pre and early-osteoarthritis of the hip radiographically in 17 patients (20 hips) for an average term of 17 years.
We measured the Sharp's angle, CE angle, AC angle, acetabular head index, and radiographical stage at first consultation. Two of 11 hips developed early-osteoarthritis from pre-osteoarthritis and seven of 9 hips developed advanced-stage osteoarthritis from early osteoarthritis at the last consultation. However, no radiographical parameters have relationship with advance of stage. It was concluded that predicting advance of stage in osteoarthritis of the hip was difficult using radiographical parameters.
