Our aim was to assess the effectiveness of a protocol involving
a standardised closed reduction for the treatment of children with
developmental dysplasia of the hip (DDH) in maintaining reduction
and to report the mid-term results. A total of 133 hips in 120 children aged less than two years
who underwent closed reduction, with a minimum follow-up of five
years or until subsequent surgery, were included in the study. The
protocol defines the criteria for an acceptable reduction and the
indications for a concomitant soft-tissue release. All children
were immobilised in a short- leg cast for three months. Arthrograms
were undertaken at the time of closed reduction and six weeks later. Follow-up
radiographs were taken at six months and one, two and five years
later and at the latest follow-up. The Tönnis grade, acetabular
index, Severin grade and signs of osteonecrosis were recorded.Aims
