title: [Clinical and radiological semiology of unilateral hip dysplasia in infants].
abstract: OBJECTIVE
  The much discussed subject of hip dysplasia in infants already seems well and truly exhausted, yet the simple clinical examination and frontal pelvic X ray of Unilateral Hip Dysplasia in infant reveals a semiology which is both specific and easily made conspicuous.
  
  
  METHODS
  This study is based on a prospective consecutive series of 50 cases of Hip Unilateral Dysplasia in infants.
  
  
  METHODS
  The study particularly endeavoured to find: postural, muscular, articular, spinal or cranial asymmetries, fixed positions of the foetus in utero, systematic sleep positions, three plans asymmetries on frontal pelvic X-ray.
  
  
  RESULTS
  
  
  
  RESULTS
  Unilateral Hip Dysplasia in infants was associated to a constant contralateral retraction of the abductors, to plagiocephalism and a fixed in utero position in almost half of the cases, to an asymmetrical sleep position in 3/4 of cases, and to pelvis asymmetry in 84 per cent of cases.
  
  
  CONCLUSIONS
  The possible cause of Unilateral Hip Dysplasia in infants must be evocated at surgical consultation analyzing in utero positions or sleep positions.
  
  
  CONCLUSIONS
  Treatment of dysplasia depends on how serious it is and on the asymmetries observed.
