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.
病例
三联骨盆截骨术（TPO）用于治疗儿童人群的发育性髋关节发育不良。本病例报告强调了该手术的一种新适应症。一名9岁患者因尤因肉瘤接受髋关节半关节置换术和股骨近端复合异体骨移植后出现不稳定，通过该手术恢复了髋臼覆盖。
结论
TPO可用于治疗具有开放Y形软骨的儿科患者人工髋关节置换术后的不稳定。它可恢复髋臼骨量，并应有助于未来髋臼假体植入或翻修。
