Salter Innominate Osteotomy for The Management of Developmental Dysplasia of The Hip in Children: Radiographic Analysis.

Abstract

There are a variety of described osteotomies to address acetabular dysplasia in children with Developmental Dysplasia of The Hip (DDH). This study will analyze the radiographic outcome of cases diagnosed with DDH and treated with a Salter innominate osteotomy. A retrospective review of all patients who underwent Salter innominate osteotomy between January 2017 and January 2019 at our institution was performed. 48 procedures (44 patients were evaluated for acetabular index (AI) and center edge angle (CEA) based on the preoperative, immediate postoperative, and the most recent pelvic x-ray. 48 procedures (44 patients) were radiologically evaluated. The AI improved from 34° preoperatively to 19.9° on the final follow up radiograph and the CEA improved from -2.4° preoperatively to 24.6° on the final follow up radiograph. In our hands, use of Salter innominate osteotomy for acetabular dysplasia in patients with DDH was associated with good radiological outcomes. The Salter innominate osteotomy was able to improve lateral acetabular coverage of the hip to almost near-normal radiographic values. Therapeutic IV.
