Hip arthroplasty in young patients requires thoughtful preoperative planning. Patients with proximal femoral bone loss complicate this planning and may require a staged procedure to optimize implant insertion. We report on a case of a 26-year-old woman with secondary hip arthritis from developmental dysplasia of the hip and a large pertrochanteric bone cyst that was treated with staged total hip arthroplasty. The cyst was decompressed and filled with an osteoconductive and osteoinductive bone graft substitute called EquivaBone. One year later, the patient underwent a successful primary total hip arthroplasty. Fifteen-month follow-up after her hip replacement revealed resolution of postoperative pain and significant functional improvement.
年轻患者的髋关节置换术需要进行周全的术前规划。股骨近端骨质流失的患者会使这一规划变得复杂，可能需要分阶段手术以优化植入物的置入。我们报告一例26岁女性患者，因髋关节发育不良继发髋关节炎，伴有一个大的转子间骨囊肿，采用分阶段全髋关节置换术进行治疗。囊肿被减压，并填充了一种名为EquivaBone的具有骨传导性和骨诱导性的骨移植替代物。一年后，患者成功接受了初次全髋关节置换术。髋关节置换术后15个月的随访显示术后疼痛消失，功能有显著改善。
