RELATIONSHIP OF BIRTH-WEIGHT AND CONGENIT AL DYSPLASIA OF HIP (CDH) IN NEWBORN CHILDREN

In 2018 consecutive newborn ultrasound examination of the hip was perf ormed according to the method of Graf within the first 14 days of life (average 4th day). Typ IIa was seen as normal in newborn childs. Birt h weight was classified according to standards of Lubchenco and Hohena uer. Newborn with high birth weight (LGA) revealed an incidence of CDH (Typ IIc according to Graf or worse) nearly twice as high as in norma l weighted newborn (AGA) (6.11% vs 3.51% [Lubchenco] and 7.95 vs 3.09 [Hohenauer]). Even in children with birth weight between 75th and 90th percentile we found a CDH incidence of 5.54%. Ultrasound examination of the hip is suggested in newborn children with high birth weight bec ause of a higher risk for development of a CDH. Other risk-factors lik e breech position or of CDH.
