This 1999 current concepts review by Tönnis and Heinecke examined 356 hips in 181 patients using CT and plain radiographs. It asked whether abnormal femoral and acetabular anteversion — quantified together as the McKibbin instability index — predicts hip pain, rotational deficits, and osteoarthritis. The study also evaluated outcomes of rotational osteotomy to restore normal anteversion in hips with dysplasia-related osteoarthritis.
