研究设计、作者经验和文献综述。目的比较不同翻修技术在治疗椎弓根减影截骨术(PSO)后种植失败中的作用。背景资料总结：椎弓根减影截骨术的并发症发生率明显高于其他可用于治疗脊柱矢状面失衡的矫治方法：尤其是硬件故障和机械并发症影响该技术，其生物力学解释仍纯属推测。方法对PSO术后失败的翻修技术的作者的经验和文献进行讨论。在我们的经验中，主要的目标是通过后路(矫正、硬件修改和实施)恢复脊柱平衡，并获得坚实的前路融合(通过传统的前路或微创的横突入路)。结论PSO的疗效应与文献报道的高风险相平衡。PSO术后翻修手术的处理可能需要增加前柱支撑以维持矫正和减少并发症。
Study design Author experience and literature review. Objectives To compare different revision techniques in the treatment of implant failure after pedicle subtraction osteotomy (PSO).Summary of background data The complication rate of pedicle subtraction osteotomy is substantially higher than other corrective procedures available for the treatment of spinal sagittal imbalance: in particular, hardware failures and mechanical complications affect this technique and their biomechanical explanation is still purely speculative.Methods The author's experience and the literature regarding the revision techniques for PSO failures are discussed.Results In this paper, eight consecutive revision cases due to rod breakage after PSO surgery are reported. In our experience, the main goals are to restore the spinal balance, through a posterior approach (correction and hardware revision and implementation) and to get a solid anterior fusion (both through a traditional anterior approach or minimally invasive transpsoas approach).Conclusion The efficacy of PSO should be balanced with the high risk of the procedure reported in the literature. Management of revision surgery after PSO may require the addition of anterior column support to maintain correction and reduce complications.
