Intra-articular malignant lesions of the hip present significant challenges. Resection often requires large resection of the acetabular bone and pelvic columns. Concurrent reconstruction options after intra-articular hip tumors are challenging and may necessitate the use of techniques and implants with uncertain long-term survivorship. We present a case of an intra-articular hip malignancy with extra-articular resection and preservation of the acetabular columns with reconstruction using a cementless acetabular shell fixed with screws.
髋关节的关节内恶性病变带来了重大挑战。切除通常需要对髋臼骨和骨盆柱进行大范围切除。关节内髋关节肿瘤切除术后的同期重建选择具有挑战性，可能需要使用长期生存率不确定的技术和植入物。我们报告一例关节内髋关节恶性肿瘤病例，采用关节外切除并保留髋臼柱，使用螺钉固定的非骨水泥髋臼杯进行重建。
