Incidence of Acetabular Dysplasia in Asymptomatic Sudanese Adults

Abstract

Objectives: The overall aim of this study is to evaluate the incidence of acetabular dysplasia in asymptomatic Sudanese adults. Methods: This is a cross-sectional population-based study, which includes radiographic examination of the Hip. A total of 240 hips are studied in scout view which is routinely done in patients undergoing CT KUB. The morphology of acetabulum is assessed by measuring the center edge angle (CEA), acetabular angle, acetabular depth to width ratio. Results: The study shows that the mean center edge angle is 36.07° (SD±5.74°), 36.01° (SD ±3.37°) for the Rt and Lt hips respectively. Mean acetabular angle is 37.5° (SD±3.7°) for the Rt and 36.9° (SD±3.9°) for the Lt hip, mean depth to width ratio is 0.3 (SD±0.03) and .29 (SD±.03) for the both hips respectively. The CEA is dysplastic in 1.7%, the acetabular depth/width ratio in 19.2% and the acetabular angle in 0.8% of the hips. The study shows statistical significant relationship between male gender and abnormal acetabular angle. Also, there is statistical significant relationship between left side and center-edge angle dysplasia. Conclusions: the incidence of hip dysplasia in Sudanese population is found to be higher when compared to South Asian and Indian population and lower than Sami and other Asian population.
