经后路椎弓根系统椎体内植骨治疗胸腰椎骨折的对比研究

目的观察和分析经后路椎体内撑开植骨治疗胸腰段压缩骨折的效果。方法采用经后路椎体内撑开植骨治疗胸腰段压缩骨折106例,并进行随访分析,观察神经损伤以及骨折椎体高度的变化情况。结果除神经损伤ASIA分级为A级的10例无变化外,其余都有不同程度的恢复。骨折椎体平均高度(为伤椎前缘高度/伤椎体高度和×100%):术前(%)59.41±9.53,术后(%)95.28±10.30,6个月后随访(%)93.96±11.51。椎管受阻狭窄程度:按Wolter分类,术前指数1为30例,指数2为64例,指数3为12例;术后指数0为92例,指数1为14例。内固定物无发生折断、折弯等。结论为建立脊柱的稳定,对椎体明显爆裂压缩的患者在手术复位内固定的同时行椎体植骨是必要的,经后路椎体内撑开植骨治疗胸腰段压缩骨折是较为有效,方便的方法之一。

Contrast Study on Opens After the Rear Guard Centrum in Plant the Bone Treatment chest Waist Section Compression Bone Fracture

Objective The observation and the analysis opens after the rear guard centrum in plant the bone treatment chest waist section compression bone fracture the effect. Methods uses after the rear guard centrum in opens plants the bone treatment chest waist section compression bone fracture 106 examples, and carries on the revisit analysis, the observation neurotrosis as well as the bone fracture centrum high change situation. Results The result is a level 10 exampies does not have the change besides the neurotrosis ASIA graduation, other have the varying degree restoration. Before bone fracture centrum average height technique, （ % ） 59.41 ± 9.53, after the technique, （ % ） 95.28 ±10.30, a half year later makes a follow - up visit （ % ） 93.96 ±11.51. The neurocanal is blocked the narrow degree： According to the Woher classification, before the technique, index 1 （30 examples）, index 2 （64 examples）, index 3 （12 exampies）, after the technique, index 0 （92 examples）, index 1 （ 14 examples）. In the fixture not occurs breaks off, the knee bend and so on. Conclusion In order to establish spinal column＇s stability, ruptures the compression obviously to the centrum the patient in the surgery repositions the fixed same fashionable centrum to plant the bone is necessary, opens after the rear guard centrum in plants the bone treatment chest waist section compression bone fracture is more effective, facilitates one of methods.
