Advantages of Single-Stage Surgical Treatment with Salter Innominate Osteotomy and Pemberton Pericapsular Osteotomy for Developmental Dysplasia of Both Hips

Abstract

This study retrospectively compared the clinical and radiological outcomes of patients with bilateral developmental dysplasia of the hip who underwent either a single-stage operation (using a Salter innominate osteotomy for one hip and a Pemberton pericapsular osteotomy for the other hip) or a two-stage procedure comprising consecutive operations. Extensive pre- and postoperative clinical, surgical and radiological examinations were undertaken. A total of 63 patients received the single-stage operation (group A), and 55 patients received consecutive operations (group B). There were no significant between-group differences in acetabular index or centre-edge angle correction. Group A had significantly reduced anaesthetic exposure, duration of hospitalization, blood transfusion volume, antibiotic costs and hospitalization costs. Group A also had a lower rate of surgical complications and avascular necrosis than group B. The single-stage surgical procedure was more economical and allowed more rapid recovery than two consecutive operations. The surgical and anaesthesia team must be highly proficient in order to perform single-stage operations successfully.
