Classically, patients with advanced lytic disease of the acetabulum secondary to metastatic bone disease are treated with complex arthroplasty reconstruction techniques. Advancements in percutaneous techniques have extended the indications for safer, minimally invasive procedures for patients with periacetabular metastasis without the need for complex hip replacement and the complications that follow it. The purpose of this report is to revisit the management of this group of patients and provide indications for an alternative minimally invasive joint-sparing technique. We describe a novel technique using a combination of percutaneous cryoablation, cementoplasty and two-screw fixation. With careful consideration of indications, excellent functional and oncologic outcomes one year after surgery is possible without the need for additional procedures.

传统上，继发于转移性骨病的晚期髋臼溶解性疾病患者采用复杂的关节成形术重建技术进行治疗。经皮技术的进步扩大了对髋臼周围转移患者进行更安全、微创手术的适应症，而无需复杂的髋关节置换术和随之而来的并发症。本报告的目的是重新审视这组患者的管理，并为替代微创关节保留技术提供指征。我们描述了一种结合经皮冷冻消融术、牙骨质成形术和双螺钉固定的新技术。在仔细考虑适应症的情况下，无需额外手术即可在术后一年获得出色的功能和肿瘤学结果。
