title: Late recurrence of developmental dysplasia of the hip following Pavlik harness treatment until normal ultrasound appearance.
abstract: OBJECTIVE
  Establish whether recurrent dysplasia once a dysplastic hip has been treated to ultrasonographic normality is possible.
  
  
  METHODS
  370 babies were referred to a hip ultrasound clinic from June 2005 to 2007 to assess for dysplasia. 96 dysplastic hips underwent appropriate treatment until normal hip morphology achieved on follow-up ultrasounds. Minimum further 12 months follow-up.
  
  
  RESULTS
  3 children (4%) developed late recurrence of dysplasia. Two required a plaster hip spica. One had an additional adductor tenotomy. One required late pelvic osteotomy.
  
  
  CONCLUSIONS
  This study highlights the need for long-term follow-up of dysplastic hips with an early pelvic X-ray at around six months.
