Acetabular reconstruction after resection of advanced periacetabular metastatic lesion is a complex undertaking. Harrington (J Bone Joint Surg [Am]. 1981;63-653) described a reconstructive technique in class III- and IV-type resections using threaded Steinmann pins and acrylic cement. This technique, although effective for pain relief and restoration of function, is traditionally considered when patient's life expectancy is short because of its questionable durability. A 17-year follow-up of our patient with plasma cell cytoma of the ilium and acetabulum, treated with a modification of the above technique after intralesional curettage, showed no mechanical failure or loosening. This suggests that the construct can be durable where there is no recurrence of disease and can also be a valuable asset in selected nontumor cases in adjunct to contemporary techniques.
髋臼周围转移性肿瘤晚期切除后的髋臼重建是一项复杂的工作。Harrington（J Bone Joint Surg [Am]. 1981;63-653）描述了在 III 型和 IV 型切除中使用螺纹斯氏针和丙烯酸水泥的重建技术。尽管该技术在缓解疼痛和恢复功能方面有效，但由于其耐久性存在疑问，传统上仅在患者预期寿命较短时才考虑使用。我们对 1 例浆细胞瘤累及髂骨和髋臼的患者采用上述技术进行瘤内刮除术后进行了 17 年的随访，结果显示无机械故障或松动。这表明，在没有疾病复发的情况下，该结构可以持久，并且在某些非肿瘤病例中，与现代技术联合使用也具有重要价值。
