Adult acetabulo e pelvic parameters in Turkish society: A descriptive radiological study

Objective: The aim of this study was to measure the prevalences of the acetabular index, collodiaphysealangle, CE angle, articulo-trochanteric distance, cross-over sign and posterior wall sign in healthy Turkishpeople, in order to shed light on the production of orthopedic medical products.Methods: In this study, both hips (a total of 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 leftarticulo-trochanteric distance was 19.10± 4.58 mm. The CE angle was 35.11±7.41in the right hip and35.37±6.76in the left hip. The acetabular index was 37.58±5.30in the right hip and 37.80±4.82inthe left hip. The collodiaphyseal angle was 138.60±8.27in the right and 137.84±8.01in 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 ofposterior 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, acetabularindex, collodiaphyseal angle, CE angle and articulo-trochanteric distances of a healthy Turkish populationbetween the ages of 18 and 65 years.
