Orthopaedic and reconstructive surgeons are faced with large defects after the resection of malignant tumours of the sacrum. Spinopelvic reconstruction is advocated for resections above the level of the S1 neural foramina or involving the sacroiliac joint. Fixation may be augmented with either free vascularized fibular flaps (FVFs) or allograft fibular struts (AFSs) in a cathedral style. However, there are no studies comparing these reconstructive techniques.

游离血管化腓骨皮瓣和同种异体腓骨支柱移植物对骶骨恶性肿瘤脊柱盆腔重建的比较。

骨科和重建外科医生在切除骶骨恶性肿瘤后面临较大的缺损。对于 S1 神经孔水平以上或涉及骶髂关节的切除术，提倡脊柱骨盆重建术。固定可以通过游离血管化腓骨皮瓣 (FVFs) 或同种异体腓骨支柱 (AFSs) 以大教堂式增强。然而，没有研究比较这些重建技术。
