经椎弓根Tenor系统与Harrington棒系统治疗胸腰椎骨折的比较

Comparative Study Between Pedicle of Vertebral Arch Tenor System and Harrington Device Fixation in Treatment of Thoracolumbar Fracture

目的 评价经椎弓根Tenor短节段系统和Harrington装置对胸腰段脊柱骨折的疗效。方法 通过回顾分析的方法 ,对 3 5例应用Tenor短节段系统和Harrington装置内固定术的胸腰段脊柱骨折病人的扩后临床资料进行比较分析。结果 经 6个月～ 1年的跟踪随访 ,应用Tenor系统固定的病例 ,骨折复位良好 ,达 96 7% ,畸形矫正完全 ,并发症明显低于Harrington装置内固定 (P <0 0 5 ) ,未发现继发神经损害。术后神经功能均有不同程度的恢复 ,按Frankel分级提高 1～ 3级。结论 经椎弓根Tenor短节段系统较非椎弓根钉系统有更好的骨折复位效果 ,固定可靠 ,并发症少 。

Objective To evaluate the different effects of the treatment of thoracolumbar fractures by pedicle of vertebral arch Tenor system and Harrington device.Methods The clinical data of 35 cases of thoracolumbar fractures were analyzed retrospectively, 23 of them were operated with Harrington device and 12 with Tenor system.Results These cases were followed up for 6 months to 2 years. The fractures treated with Tenor system got satisfied reduction, reached about 96 7% of normal vertebral height. The deformities were completely corrected and complications were significant lower than those derived from Harrington device treatment, and no delayed neurologic damage was found. Most cases got reduction with one to three Frankel grades of neurologic recovery.Conclusion The Tenor pedicle system is more effective in treatment of thoracolumbar fracture than non-pedicle device. It can get satisfied fracture reduction , reliable fixation and less complications.
