Screening for developmental dysplasia of the hip: current practices in Ireland

Abstract

To ascertain the current approach to screen for developmental dysplasia of the hip in the Republic of Ireland. Two-pronged prospective and retrospective study. (1) Postal questionnaire to consultant paediatricians responsible for the routine neonatal care of infants in the Irish Republic in June 2006. (2) Retrospective database review to identify infants undergoing radiological follow-up and their outcome. All maternity units surveyed responded. Most units (84%) were dependent on radiographs at 4-6 months for imaging hips, only two units primarily used ultrasound (10.5%). We estimate that neonatal hip examination is performed by an experienced examiner in less than 30% of routine newborn examinations. On retrospective analysis, 94% of radiographs performed were normal. The most effective interventions, selective ultrasound and examination by an experienced clinician are not widely practiced. There is a need for the development of national guidelines based on available resources.
