Methods

The study was a retrospective analysis of treatment of 30 children with developmental dysplasia of the hip (DDH). These children were taken from a consecutive series of children treated over a period from June 2000 to 2011 with closed reduction by a single surgeon. The ages at the time of diagnosis were between 1 day and 13 months (mean 5.25 weeks). Included in this series are 7 patients treated with medial open reduction, all done with the Ludloff approach. Follow up of these patients was from 8 months to 12 years (mean 5 years). All patients needing secondary procedures were noted. The X- rays were evaluated for percentage acetabulum cover in patients over the age of 8 and improvement of the acetabular index in all these patients.
