Abstract

Total hip arthroplasty (THA) for pathologic and impending fracture due to periacetabular multiple myeloma (MM) lesions has been reported. We report a case of radiographic progression of dysplastic osteoarthritis, complicated by periacetabular MM lesions, treated by THA. A 69-year-old female with a 13-year history of MM presented with right hip pain. Plain radiographs and CT showed that dysplastic osteoarthritis had progressed, while the periacetabular MM lesions remained unchanged. Pathologic fracture was not observed on MRI. THA with a cementless acetabular component and impaction bone grafting was done. Bone graft incorporation was confirmed on CT at 1 year after surgery. There were no signs of bone absorption or implant loosening at last follow-up 3 years after surgery. Due to the advances in the treatment of MM and antiresorptive drugs, cementless acetabular component and impaction bone grafting may be an option for dysplastic osteoarthritis complicated by acetabular bone loss due to MM.

无骨水泥髋臼假体全髋关节置换术及内嵌植骨治疗发育不良性骨关节炎合并多发性骨髓瘤。

全髋关节置换术(THA)病理性和即将发生的骨折由于髋臼周围多发性骨髓瘤(MM)病变已被报道。我们报告一例发育不良的骨关节炎的影像学进展，并发髋臼周围MM病变，经THA治疗。69岁女性，MM病史13年，表现为右髋关节疼痛。x线平片和CT显示发育不良性骨关节炎进展，而髋臼周围MM病变保持不变。MRI未见病理性骨折。采用无骨水泥髋臼假体THA和嵌塞植骨术。术后1年CT证实植骨植入。术后3年随访无骨吸收或种植体松动迹象。由于MM治疗和抗吸收药物的进步，无骨水泥髋臼假体和嵌塞骨移植可能是治疗MM所致发育不良骨关节炎并发髋臼骨丢失的一种选择。
