Surgical Management of Pediatric Developmental Dysplasia of the Hip

In pediatric patients with developmental dysplasia of the hip with late presentation or failure of nonsurgical treatment, surgical management is indicated. The goal of surgery is to obtain a stable reduction to promote development of the femoral head and acetabulum while avoiding osteonecrosis of the femoral head and the need for further surgery. Treatment is related to the age of the patient and the degree of soft-tissue contracture or bony deformity present. As a general rule, in children aged <12 months, closed reduction and spica casting is preferred. Children aged 12 to 18 months may require open reduction, which can be performed safely through a medial or anterior approach. In children aged 18 months to 3 years, residual bony deformity can be corrected with a femoral or pelvic osteotomy in addition to open reduction. In children with complex deformity or in children aged >3 years, both pelvic and femoral osteotomies are commonly required to stabilize an open reduction.
