INTRODUCTION: Orthopaedic treatment of @entity572 ( @entity572 ) has a high success rate in cases that are diagnosed early. However, the outcomes of these @entity1 are not really known when they are subsequently diagnosed with some type of @entity73 . MATERIALS AND METHODS: A retrospective observational study was conducted on cases of @entity572 with a poor outcome after orthopaedic treatment, being unknown if they had any type of @entity1155 . The @entity1 were clinically and radiologically assessed, and afterwards received neurological valuation by the @entity1 Neurology Unit. RESULTS: Of the 325 cases of @entity572 diagnosed in 293 @entity1 , 10 @entity1 (3%) with 16 hips with @entity572 were diagnosed of any @entity73 . All them were initially treated orthopedically. Clinical and radiologically evolution was succesful only in 4 cases (25%) being necessary any surgical procedure in the remaining 12 cases. After surgical treatment we got an improvement in the Acetabular Index (p=0.005) and Reimers Extrusion Index (p=0.042). Neck-shaft angle and Wiberg CE angle also improved but this difference was not statically significant. @entity73 was diagnosed at 2,5 years of age and the begining of walking was delayed at 2.4 years of age. CONCLUSIONS: @entity73 can lead to an unfavourable outcome in the treatment of @entity572 , with the relative risk of a poor outcome being 7.2 times higher in these @entity1 . An unfavourable outcome with conventional treatment of @entity572 must make us suspect the presence of some type of @entity16 , particularly if there is a delay in walking.
