Ultrasound investigation of the hip according to @entity20661 is performed, whenever possible, as a routine screening test for @entity572 and @entity3029 in neonates. However, in spite of screening, @entity572 and/or @entity3029 is identified in a number of @entity1 after the third month of life only. The present study presents an analysis of reasons and causes. Between August 1999 and July 2001 @entity1 aged between six months and five years were documented, in whom the diagnosis of @entity572 or @entity3029 was made, despite normal ultrasound findings at primary investigation and who required non operative or operative treatment by a specialist surgeon working in Switzerland in paediatric orthopaedics. The study included 26 @entity1 (17 @entity1 / 9 @entity1 ). @entity572 and/or @entity3029 was diagnosed between the age of 6 days and 41 months. Twelve @entity1 had to be excluded from the sample (n = 26), four were @entity1 who had basic @entity16 or @entity156 and there were eight @entity1 from abroad whose original documentation could not be obtained. Analysis of the remaining 14 @entity1 showed that 43% were misdiagnosed (n = 6) and a treatment error occurred in 36% (n = 5) of cases. One @entity1 presented with a teratogenic @entity572 . In two other @entity1 with normal primary ultrasound findings, @entity572 was identified radiographically once the @entity1 started to walk. Delayed diagnosis can be the result of @entity2246 . The six @entity1 meeting the criteria of misinterpretation can be expressed as a rate of 0.04% of all births. However, even if the disorder is correctly diagnosed, its identification and treatment may be inadequate or fail to produce the desired results. This was the case for five of the @entity1 , that is, for a rate of 0.03% of births.
