Objective: This study aimed to compare the mid-term results of closed reduction (CR) versus medial open reduction (MOR) in the treatment of children with developmental dysplasia of the hip (DDH) under age 1.

Methods: Thirty-four patients with DDH (41 hips) were included in this retrospective study with a mean follow-up of 4.2 years (range: 2-6.9 years). All hips were then divided into 2 groups based on the treatment type: the CR group (20 hips) and the MOR group (21 hips). All hips from both groups were assessed with post-spica magnetic resonance imaging (MRI) in the first 24 hours, and reinterventions were recorded. Medial dye pool width was also measured.

Results: Age at the time of reduction was similar between the CR and MOR groups (6.6 ± 1.3 months vs. 6.7 ± 1.6 months). There was no significant difference between groups regarding avascular necrosis rate and further corrective surgery (FCS) requirement (P=.454, .697). The appropriate reduction was seen at 38/41 hips. Three hips in the CR group had revealed dislocation in post-spica MRIs and required re-intervention, and none of the hips in the MOR group required re-intervention (P=.107). Medial dye pool width in 3 planes showed no significant difference between MOR and CR.

Conclusion: There is no difference in the avascular necrosis rate and FCS requirements between CR and MOR under age 1. Post-spica MRI is a favorable tool for evaluating reduction after CR, but its efficacy after MOR is questionable.
