摘要(Abstract)：
[目的]椎体撬拨植骨成形加椎弓根螺钉固定治疗早期胸腰椎爆裂性骨折,预防术后形成“空心椎”引起的钉松动、断钉及伤椎再塌陷、后凸畸形等并发症。[方法及结果]收治胸腰椎爆裂性骨折患者28例,行椎弓根螺钉内固定后,用神经根探子撬拨压缩下陷的伤椎上终板和前中柱,使之复位,经伤椎通过椎弓根植骨成形。术后随访6~18个月,全部获得骨性愈合(100%)。脊柱后凸Cobb's角度术前平均23.6°(n=23)矫正至术后平均4.4°(n=23),随访角度5.3°;椎体前缘高度压缩比由术前平均45%恢复至术后97%,随访时95%;伤椎椎管内矢状径术前平均7.6 mm,术后17.5 mm,随访矢状径17.1 mm,无明显狭窄。无内固定松动、断裂或弯曲。[结论]椎体撬拨植骨成形加椎弓根螺钉固定治疗胸腰椎压缩性骨折,手术安全性高,经植骨均获得骨性愈合,恢复了伤椎的强度和刚度,减少了内固定的应力,防止后凸畸形,降低并发症出现。
