【摘要】：目的探讨经后外侧入路前后一体椎弓根钉棒系统内固定治疗胸腰椎骨折合并脊髓损伤的临床疗效。方法回顾性分析自2010-11—2014-11手术治疗的70例胸腰椎爆裂骨折合并脊髓损伤,采用后外侧入路减压联合椎弓根钉棒系统前后一体内固定治疗。结果 70例切口均一期愈合,均获得平均18(12~36)个月随访。无内固定松动、椎弓根钉断裂等并发症发生。术后1年脊髓神经功能Frankel分级均有不同程度改善。术后3 d伤椎Cobb角、伤椎前缘压缩率、伤椎后缘压缩率、椎管狭窄率较术前明显改善,差异有统计学意义(P0.05);且末次随访时与术后3 d比较差异无统计学意义(P0.05)。结论经后外侧入路前后一体椎弓根钉棒系统内固定技术具有创伤小,减压彻底,良好恢复脊柱三柱稳定性的优点,是治疗胸腰椎爆裂骨折合并脊髓损伤的有效方法。
[Abstract]:Objective to investigate the clinical effect of anterior and posterior pedicle screw system internal fixation in the treatment of thoracolumbar fractures with spinal cord injury. Methods 70 cases of thoracolumbar burst fracture complicated with spinal cord injury treated from 2010-11 to 2014-11 were analyzed retrospectively. Posterior lateral approach decompression combined with anterior and posterior internal fixation of pedicle screw system was used to treat 70 cases of thoracolumbar burst fracture. Results all the 70 incisions healed at the first stage and were followed up for an average of 18 (12 ~ 36) months. No internal fixation loosening, pedicle screw fracture and other complications occurred. 1 year after operation, the Frankel grade of spinal cord nerve function was improved to some extent. The Cobb angle, anterior compression rate, posterior compression rate and stenosis rate of injured vertebrae were significantly improved 3 days after operation (P0.05). There was no significant difference between 3 days after operation and at the last follow-up (P 0.05). Conclusion the internal fixation technique of anterior and posterior pedicle screw system through posterolateral approach has the advantages of less trauma, complete decompression and good stability of three columns of spine. It is an effective method to treat thoracolumbar burst fracture with spinal cord injury.
