Malignancies involving the pelvic ring present numerous challenges, especially in the periacetabular area. Extensive resection of the pelvic region without reconstruction can lead to severe functional impairment. Numerous reconstructive options exist, but all have drawbacks. Extracorporeally irradiated autografts are one option for reconstruction after periacetabular resections; they offer the potential advantages of eliminating the risk of allogeneic reactions associated with allografts and preserving local anatomy. However, little is known about the durability and risks of this approach in pelvic reconstruction.

II 型骨盆肿瘤切除术后采用辐照自体移植加全髋关节置换的复合重建是可行的，但充满了并发症。

涉及骨盆环的恶性肿瘤带来了许多挑战，特别是在髋臼周围区域。盆腔区域的广泛切除而不重建可能导致严重的功能障碍。存在许多重建方案，但都有缺点。体外照射的自体移植物是髋臼周围切除术后重建的一种选择；它们具有消除与同种异体移植相关的同种异体反应风险和保留局部解剖结构的潜在优势。然而，人们对这种方法在骨盆重建中的耐久性和风险知之甚少。
