The Salter Innominate Osteotomy
Developmental dysplasia of the hip (DDH), if left untreated in the young child, is known to result in early-onset hip dysfunction. Labral and chondral pathology manifests in the young adult and often results in an accelerated need for joint replacement due to the altered weight-bearing mechanics of the femoral head in a shallow acetabulum. Acetabular reorientation procedures, such as the Salter innominate osteotomy, are performed for DDH in the skeletally immature patient in order to acutely correct anterolateral acetabular deficiency by rotating the acetabular fragment about the symphysis pubis. The Salter innominate osteotomy therefore restores hip stability and may be used in combination with an open reduction and capsulorrhaphy, and/or with femoral osteotomies, as necessary. The improvement of the hip joint mechanics has also been found to induce remodeling of the acetabulum with continued growth of the child, leading to improved clinical outcomes.
