Assisted techniques (AT) for vertebral cementoplasty include multiple mini-invasive percutaneous systems in which vertebral augmentation is obtained through mechanical devices with the aim to reach the best vertebral height restoration. As an evolution of the vertebroplasty, the rationale of the AT-treatment is to combine the analgesic and stability effect of cement injection with the restoration of a physiological height for the collapsed vertebral body. Reduction of the vertebral body kyphotic deformity, considering the target of normal spine biomechanics, could improve all systemic potential complications evident in patient with vertebral compression fracture (VCF). Main indications for AT are related to fractures in fragile vertebral osseous matrix and non-osteoporotic vertebral lesions due to spine metastasis or trauma. Many companies developed different systems for AT having the same target but different working cannula, different vertebral height restoration system and costs. Aim of this review is to discuss about vertebral cementoplasty procedures and techniques, considering patient inclusion and exclusion criteria as well as all related minor and/or major interventional complications.
椎体成形术的辅助技术（AT）包括多种微创经皮系统，通过机械设备进行椎体强化，旨在实现最佳的椎体高度恢复。作为椎体成形术的一种演进，AT治疗的基本原理是将骨水泥注射的止痛和稳定作用与恢复塌陷椎体的生理高度相结合。考虑到正常脊柱生物力学的目标，减少椎体后凸畸形可改善椎体压缩骨折（VCF）患者中明显的所有全身潜在并发症。AT的主要适应证与脆弱椎体骨基质骨折以及因脊柱转移或创伤导致的非骨质疏松性椎体病变有关。许多公司开发了不同的AT系统，它们具有相同的目标，但工作套管不同、椎体高度恢复系统不同且成本各异。本综述的目的是讨论椎体成形术的操作程序和技术，同时考虑患者的纳入和排除标准以及所有相关的轻微和/或主要介入并发症。
