The essential role of ultrasound examinations in diagnosis and treatment of developmental dysplasia of the hip (DDH) is widely accepted while the weighting and correlation of protective factors and perinatal risk for DDH still give rise to debate. Our aim was to investigate the impact of single and twofold combined risk and protective factors on the newborns' hip maturity, assessed with the Graf ultrasound method. Therefore, data sets of 11,820 universally screened newborns were analyzed. Univariate and logistic regression analyses were performed to correlate risk and protective factors with mature or immature but appropriate for age and pathologic hip types. Thereby, female gender (OR 4.07 (95% CI 3.01–5.51), p < 0.001), breech presentation (4.98 (3.71–6.71), p < 0.001), and positive family anamnesis (5.05 (3.49–7.31), p < 0.001) as well as the combination of female gender with high birth weight (3.51 (2.45–5.03), p < 0.001) could be identified as independent predictive risk factors. Only low birth weight (0.27 (0.11–0.66), p = 0.004) could be identified as a single protective factor, while no combination of protective factors was significant.
