To review the development of the reconstruction methods following total sacrectomy, and to provide reference for finding a better reconstruction method following total sacrectomy.
The case reports and biomechanical and finite element studies of reconstruction following total sacrectomy at home and abroad were searched. Development and current situation were summarized.
After developing for nearly 30 years, great progress has been made in the reconstruction concept and fixation techniques. The fixation methods can be summarized as the following three strategies: spinopelvic fixation (SPF), posterior pelvic ring fixation (PPRF), and anterior spinal column fixation (ASCF). SPF has undergone technical progress from intrapelvic rod and hook constructs to pedicle and iliac screw-rod systems. PPRF and ASCF could improve the stability of the reconstruction system.
Reconstruction following total sacrectomy remains a challenge. Reconstruction combining SPF, PPRF, and ASCF is the developmental direction to achieve mechanical stability. How to gain biological fixation to improve the long-term stability is an urgent problem to be solved.
回顾全骶骨切除术后重建方法的发展历程，为寻找更好的全骶骨切除术后重建方法提供参考。
检索国内外全骶骨切除术后重建的病例报告以及生物力学和有限元研究，总结其发展历程与现状。
经过近30年的发展，重建理念和固定技术取得了巨大进步。固定方法可归纳为以下三种策略：脊柱骨盆固定（SPF）、骨盆后环固定（PPRF）和脊柱前路固定（ASCF）。SPF已从盆腔内棒和钩结构发展到椎弓根和髂骨螺钉-棒系统。PPRF和ASCF可提高重建系统的稳定性。
全骶骨切除术后重建仍然是一项挑战。结合SPF、PPRF和ASCF的重建是实现机械稳定性的发展方向。如何获得生物固定以提高长期稳定性是亟待解决的问题。
