后路钉棒内固定对腰椎骨折患者神经功能和椎体指标的改善作用

Effects of posterior screw and rod fixation on nerve function and vertebral indicators in patients with lumbar vertebral fracture

目的 观察后路钉棒内固定对腰椎骨折患者神经功能和椎体指标的改善.方法 32例腰椎骨折患者采用后路钉棒内固定治疗,根据术前脊髓神经损伤Frankel评定分级：A级1例,B级7例,C级12例,D级12例,E级0例,术前Cobb角为（28.1±3.9）°,伤椎前缘高度比（44.3±9.2）％.比较治疗前后患者神经功能和椎体指标.结果 平均随访22.3个月.脊髓神经损伤Frankel评定分级：A级1例,B级3例,C级9例,D级15例,E级4例；术后神经功能均有提高（均P＜0.05）；术后Cobb角为（4.7±0.8）°,伤椎前缘高度比（82.3±12.7）％,术后伤椎前缘高度比和Cobb角均有改善（均P＜0.01）.结论 后路钉棒内固定可以明显改善腰椎骨折患者的神经功能和椎体指标.

Objective To observe the effects of posterior screw and rod fixation on nerve function and verte- bral indicators in patients with lumbar vertebral fracture. Methods The clinical data of 32 cases with lumbar verte- bral ii＇acture were analyzed retrospectively. According to Frankle grading：grade A 1 case;grade B 7 cases;grade C 12 cases;grade D 12 cases. All the patients were treated by posterior screw and rod fixation. The nerve function and verte- bral indicators were compared. Results Followed-up for 22.3 months, according to Frankle grading： grade A 1 ease ; grade B 3 cases;grade C 9 cases;grade D 15 cases;grade E 4 cases. The nerve functions were improved after opera- tion. There was a significant difference between before and after treatment （ all P 〈 0.05 ）. The the height of the front edge of the fractured vertebral and cobb angle were improved after operation（ all P 〈 0.01 ）. Conclusion Posterior Screw and rod fixation can significantly improve nerve function and vertebral indicators in patients with lumbar verte- bral fracture.
