Source abstract
CASE: Triple pelvic osteotomy (TPO) is used to treat developmental dysplasia of the hip in a pediatric population. This case report highlights a new indication for this procedure. Acetabular coverage was restored in a 9-year-old patient who experienced instability following hip hemiarthroplasty and proximal femur composite allograft implantation for the treatment of Ewing sarcoma. CONCLUSION: TPO can be used to treat instability following prosthetic hip replacement in pediatric patients with open triradiate cartilage. It restores the acetabular bone stock and should facilitate future acetabular component implantation or revisions.
