One-stage treatment of developmental dysplasia of the hip in untreated children from two to five years old. A comparative study.

A total of 38 children (49 hips) were retrospectively investigated to assess the efficacy and safety of one-stage treatment of developmental dysplasia of the hip (DDH) in untreated children from two to five years of age. Our method consisted of open reduction, Salter innominate osteotomy, femoral shortening and derotation osteotomy. The patients were distributed into two groups according to the age at which they were operated: Group I included 19 patients aged < 3 years (24 hips) and Group II included 19 patients aged > or = 3 years (25 hips).

Medial open reduction of developmental dysplasia of the hip using the Weinstein-Ponseti approach.

Objective: To evaluate the efficacy and safety of medial open reduction using the Weinstein-Ponseti approach to treat developmental dysplasia of the hip (DDH).

Methods: In this retrospective study, 35 hips were treated in 24 children (one boy and 23 girls, mean age 10.8+/-2.
