摘要目的 研究经椎弓根伤椎植骨置钉术对胸腰椎骨折患者的临床效果.方法 选取2017年5月至2018年5月兴宁市人民医院治疗的胸腰椎骨折患者50例,采用随机数字法将其分为对照组和观察组,每组25例.对照组行常规跨伤椎后路复位内固定术治疗,观察组行经椎弓根伤椎植骨置钉术治疗.比较两组患者的治疗总有效率、手术预后情况以及术前后和末次随访时的椎体各指标水平.结果 观察组治疗总有效率(96.00％)高于对照组(76.00％,P<0.05);观察组手术时间、术中出血量、内固定后引流量、住院时间以及手术后和末次随访时的Cobb角、椎管侵占率水平均低于对照组(P均<0.05),椎体前高压缩比水平高于对照组(P<0.05).结论 经椎弓根伤椎植骨置钉术治疗胸腰椎骨折患者的手术效果显著,能明显加固骨折部位,改善患者手术情况,加快术后恢复,值得临床推广.

abstractsObjective To study the clinical effect of pedicle screw internal fixation vertebra grafting on thoracolumbar fractures. Methods Fifty patients with thoracolumbar fracture treated in Xingning People's Hospital from May 2017 to May 2018 were selected. Random number method was used to divide them into control group and observation group, with 25 cases in each group. The patients in the control group underwent conventional trans-traumatic posterior reduction and internal fixation. The patients in the observation group underwent pedicle screw internal fixation vertebra grafting. The total effective rate of the two groups were compared, and the prognosis of operation and the level of vertebral body indexes before and after operation and at the last follow-up were compared between the two groups. Results The total effective rate in the treatment group (96. 00％) was higher than that in the control group (76. 00％, P<0. 05). The operation time, intraoperative bleeding volume, drainage volume after internal fixation, hospitalization time, Cobb angle and spinal canal encroachment rate after operation and the last follow-up in the observation group were significantly lower than those in the control group ( P all<0. 05 ) , and the compression ratio of anterior vertebral body was higher than that in the control group ( P<0. 05 ) . Conclusions Pedicle screw fixation vertebra bone grafting has significant surgical effect on thoracolumbar fractures, which can significantly strengthen the fracture site, and significantly improve the patient's surgical conditions and accelerate postoperative recovery, so it is worthy of promotion.
