摘　　要：目的：结合临床实践，分析新型椎弓根固定器的设计特点和复位作用。方法：本组治疗胸腰椎骨折１８ 例， 男１２ 例，女６ 例，年龄１８ ～５２ 岁，平均３４ 岁，随访时间８ ～１９ 月，平均１１ ２ 月。结果：压缩椎体高度由术前的５１８ ％ 恢复到术后的９２３ ％ ， 后凸角由术前２２６°矫正至术后４８°。５ 例径 Ｃ Ｔ测量椎管矢状径由术前７ ｍ ｍ 改善术后１２ ｍ ｍ 。结论：新型椎弓根固定器具有操作简便。复位满意，椎管间接减压和固定坚强，有效地解决了原有椎弓根内植物存在的问题。Aim:The design features and reduction efficaty of a new pedicle screw fixator were analyzed according to clinical practice.Methods:This instrument was used in 18 patients with thoracolumbar fractures.Of these patients there were 12 males and 6 females.The ages of the patients ranged from 18 to 52 years (an average of 34 years).All were followed up for 8 to 19 months,with an average of 11.2 months.Results:Height of compressed vertebral bodies were restored from 51.8% to 92.3% of the normal height.Kyphotic deformity was corrected from 22.6° preopratively to 4.8° postoperatively. CT evaluation showed that sagittal diameter of vertebral canal was restored from 7mm preoperatively to 12mm postoperatively in 5 patients.Conclusions:New pedicle screw fixator possessed the advantages of simpler manipulation, good reduction, indirect spinal decompression and rigid fixation.Several problems about the pedicle screw implant were solved.
