MATERIAL AND METHODS In the German multicenter network for congenital uro-rectal malformations (CURE-Net) database symphysis diastasis width was determined either radiologically or intraoperatively in 82 CBE individuals. Pelvic radiographs, available in 67 CBE patients, were screened for pathological hip findings such as hip dysplasia or coxarthrosis. RESULTS The median symphysis diastasis was 5 cm (IQR 4–6). Radiologically measured symphysis width was available in 48 individuals (67 % male, median 12 years; 33 % female, median 11 years). Hereby, females showed a significantly wider diastasis than males (median 6 cm vs. 4 cm; p = 0.02). Subgroup analysis revealed no statistically significant difference regarding previous sym- physis approximation or the kind of initial reconstruction. Radiographs showed hip dysplasia in 12 individuals (18 %; 5 female, 7 male; median age 15 years), the majority of them (83 %) had undergone symphysis approximation in childhood (symphysis diastasis median 4.5 cm (IQR 4–6)). Two further male adults 50 years and older (3 %) presented with coxarthrosis; both had symphysis rediastasis of 4 cm after previous approximation. CONCLUSIONS It is known fact that symphysis diastasis persists in the long-term, even after symphysis approxima- tion. Females with CBE have a significantly wider symphysis diastasis suggesting a gender-specific influence of their pelvic shape. Hip dysplasia and coxarthrosis may occur in a considerable amount of CBE patients. Therefore, hip complaints should be adequately diagnosed and treated.
