2The spine fracture model is a type of instability spine model, it is satisfacted for the test. The new PETF can offer good three-dimensional stabilization to instability fracture spine.it has clinical feasibility . [3]To be a minimally-invasive surgical procedure ,the PETF assistanted microendoscopy can combine decompression and reduction with external fixation for the injuried vertebral colunm without segments fusion.

(1)骨折模型B组是不稳定性骨折模型，满足实验的要求，新型脊柱外固定器能为不稳定性骨折脊柱提供良好的三维稳定，具有临床可行性；(2)轴向压缩实验A组、C组和D组之间的差异均具有显著统计学意义，说明单纯新型脊柱外固定器是一种弹性固定，抗压刚度不够，但新型脊柱外固定器结合PVP术后抗压能力明显，但较正常标本仍有一定的差距，手术后短期内有必要适当腰部支柱保护；(3)新型脊柱外固定器联合MED和PVP术治疗胸腰椎骨折的微创技术能减轻病人的痛苦、达到胸腰椎骨折的治疗目的和效果，并具有非融合性固定的特点，具有较大的临床推广应用价值。
