... 3960 hips) of 1980 individuals (1178 males, 802 females) from nine different cities between the ages of 18 and 65 years were measured and statistically analyzed. Results: The right articulo-trochanteric distance of all participants was 19.67 ± 4.52 mm and the left articulo-trochanteric distance was 19.10 ± 4.58 mm. The CE angle was 35.11 ±7.41 in the right hip and 35.37 ±6.76 in the left hip. The acetabular index was 37.58 ±5.30 in the right hip and 37.80 ±4.82 in the left hip. The collodiaphyseal angle was 138.60 ±8.27 in the right and 137.84 ±8.01 in the left hip. The prevalence of cross-over sign in the right hip was 6.46% and 6.66% for the left hip. The prevalence of posterior wall sign was 4.24% for the right hip and 4.19% for the left hip. Conclusion: This study has provided prevalence values of cross-over sign, posterior wall sign, acetabular index, collodiaphyseal angle, CE angle and articulo-trochanteric distances of a healthy Turkish population between the ages of 18 and 65 years.
