目的探讨后外侧植骨椎弓根系统内固定同期病灶清除治疗胸腰椎结核的疗效。方法总结我科行后外侧植骨椎弓根系统内固定同期病灶清除治疗胸腰椎结核患者 48例 ,随访时间 1 5— 5 5年 ,平均 3 6年。内容包括植骨融合率、截瘫恢复情况和后凸畸形矫正状况。结果所有患者均显示骨性融合 ;38例合并截瘫的患者中 ,症状改善 35例 ;术后后凸畸形平均矫正 2 9 1° ,1 5— 5 5年后随访 ,后凸角度平均丢失 3 2°。结论后外侧植骨椎弓根系统内固定同期病灶清除可恢复脊柱的即刻稳定性 ,有利于骨融合 ,促进截瘫恢复和防止截瘫复发 ,矫正及预防后凸畸形
Objective To investigate the therapeutic effect of posterior lateral bone graft pedicle screw fixation in the treatment of thoracolumbar tuberculosis. Methods Forty-eight patients with thoracolumbar tuberculosis who were treated with posterolateral pedicle instrumentation and internal fixation of pedicle screw system were retrospectively reviewed. The follow-up time ranged from 15.5 to 55 years (mean, 36 years). Including bone fusion rate, paraplegia recovery and kyphosis correction status. Results All the patients showed bony fusion. Among the 38 patients with paraplegia, the symptoms were improved in 35 cases. The mean length of kyphosis was 291 ° and 15-5 years respectively. The mean corneal angle was 3 2 °. Conclusion Posterior lateral debony pedicle instrumentation can be used to restore the immediate instability of spine, which can promote bone fusion, promote the recovery of paraplegia and prevent recurrence of paraplegia, and correct and prevent kyphosis
