Staged Bilateral Total Hip Arthroplasty in an Adolescent Patient With Multiple Epiphyseal Dysplasia and Bilateral Avascular Necrosis

Abstract

Multiple epiphyseal dysplasia is a rare congenital disorder characterized by irregular, delayed ossification at multiple epiphyses, typically in the lower extremity. In this arthroplasty in rare conditions case report, we present a 14-year-old female with multiple epiphyseal dysplasia and borderline acetabular dysplasia who developed progressive bilateral femoral head avascular necrosis. She presented with a worsening antalgic gait and bilateral hip pain starting at 10 years of age, which was refractory to nonoperative measures. She was treated with staged bilateral total hip arthroplasty when her triradiate cartilage was closed and is presenting with 3 years of clinical follow-up with excellent reported outcomes. The goal of this case presentation is to discuss the specific surgical challenges related to this patient population and highlight important considerations in the adolescent population undergoing total hip arthroplasty.
