Limb-salvage surgery for pelvic sarcomas remains one of the most challenging surgical procedures for musculoskeletal oncologists. In the past several decades, various surgical techniques have been developed for periacetabular reconstruction following pelvic tumor resection. These methods include endoprosthetic reconstruction, allograft or autograft reconstruction, arthrodesis, and hip transposition. Each of these procedures has its own advantages and disadvantages, and there is no consensus or gold standard for periacetabular reconstruction. Consequently, this review provides an overview of the clinical outcomes for each of these reconstructive options following pelvic tumor resections. Overall, high complication rates are associated with the use of massive implants/grafts, and deep infection is generally the most common cause of reconstruction failure. Functional outcomes decline with the occurrence of severe complications. Further efforts to avoid complications using innovative techniques, such as antibiotic-laden devices, computer navigation, custom cutting jigs, and reduced use of implants/grafts, are crucial to improve outcomes, especially in patients at a high risk of complications.

盆腔肉瘤保肢手术仍然是肌肉骨骼肿瘤学家最具挑战性的外科手术之一。在过去的几十年中，已经开发了各种手术技术用于盆腔肿瘤切除后的髋臼周围重建。这些方法包括内假体重建、同种异体或自体移植重建、关节融合术和髋关节转位。这些手术中的每一个都有其优点和缺点，对于髋臼周围重建没有共识或金标准。因此，本综述概述了盆腔肿瘤切除术后每种重建方案的临床结果。总体而言，高并发症率与使用大量植入物/移植物有关，而深部感染通常是重建失败的最常见原因。功能结果随着严重并发症的发生而下降。进一步努力使用创新技术避免并发症，例如含抗生素的设备、计算机导航、定制切割夹具和减少植入物/移植物的使用，对于改善预后至关重要，特别是对于并发症高风险的患者。
