胸腰椎骨折患者行骨折复位术后应用椎弓根椎体内植骨的临床效果分析

Clinical effect of bone graft in vertebral pedicle vertebra after fracture reduction on patients with thoracolumbar fractures

目的分析胸腰椎骨折患者行骨折复位术后应用椎弓根椎体内植骨的临床效果。方法回顾性分析该院2016-03～2017-03收治符合纳入标准的胸腰椎骨折患者60例(均行椎弓根椎体内植骨治疗,所有患者随访1年)椎体高度比、植入骨块、骨缺损相对面积变化情况。结果患者术后即刻与术后1年椎体前缘高度比及椎体后缘高度比均高于术前,差异有统计学意义(P <0.05);患者术后即刻与术后1年椎体前缘高度比及椎体后缘高度比差异均无统计学意义(P> 0.05);患者椎体前缘高度比丢失与椎体后缘高度比丢失差异无统计学意义(P> 0.05)。患者术后6个月植入骨块及骨缺损相对面积均低于术后即刻,差异有统计学意义(P <0.05);患者术后1年植入骨块及骨缺损相对面积均低于术后6个月及术后即刻,差异有统计学意义(P <0.05)。结论经椎弓根椎体内植骨能较好地减少矫正度丢失,但无法使椎体内空隙恢复。

Objective To explore the clinical effect of bone graft in vertebral pedicle vertebra after fracture reduction on patients with thoracolumbar fractures. Methods The clinical data of 60 patients with thoracolumbar fractures admitted to our hospital from March 2016 to March 2017 were retrospectively analyzed. All the patients were treated with pedicle intravertebral bone grafting and were followed up for 1 year. The vertebral height ratio, bone graft and relative area of bone defect were analyzed. Results Immediately after surgery, and 1 year after surgery, the height ratio of vertebral anterior edge and the height ratio of vertebral posterior edge were all higher than those before surgery, and the differences were statistically significant( P <0.05). There were no significant differencesly in the height ratio of vertebral anterior edge and the height ratio of vertebral posterior edge between immediate and 1 year after surgery( P >0.05). There was no significant difference between the loss of anterior edge height ratio and the loss of posterior edge height ratio( P >0.05). The bone graft block and the relative area of bone defect six months after operation were all less than those immediately after operation and the differences were statistically significant( P <0.05). The bone graft block and the relative area of bone defect of the patients one year after surgery were lower than those of the patients six months after surgery and immediately after surgery, and the differences were statistically significant( P <0.05). Conclusion Bone grafting in vertebral pedicle can reduce the loss of correction, but can not restore the vertebral space.
