椎體后凸成形術治療無神經損傷的a3.1型骨質疏松性胸腰椎爆裂性骨折

1、 椎體后凸成形術治療無神經損傷的 A3.1 型骨質疏松性胸腰椎爆裂性骨折 中文摘要 [目的 目的] 回顧性研究應用椎體后凸成形術 （Kyphoplasty,KP） 治療無神經損傷的 A3.1 型骨質疏松性胸腰椎爆裂性骨折，探討其可行性及其療效。 [方法 方法] 隨訪我科自 2007 年 1 月至 2010 年 10 月間應用椎體后凸成形術治療無神經損傷的 A3.1 型骨質疏松性胸腰椎爆裂性骨折的病例， 對隨訪資料完整的 40 例病例進

2、行療效分析。分別于術前、術后及末次隨訪時采用視覺模擬評分法（visual analogue scales,VAS） 、Oswestry 功能障礙指數（Oswestry Disability Indexes,ODI）評估患者疼痛和日常生活功能，并測量術前、術后及末次隨訪時骨折椎體前緣、中緣、后緣的高度，Cobb 角及椎管內骨塊占位率。采用重復測量方差分析，比較術前、術后及末次隨訪時的數據。 [結果 結果] VAS 評分由術前 8.2

3、77;0.9 降至術后 3.0±0.8， 末次隨訪時 VAS 評分為 3.2±0.7。 ODI評分由術前 71.7%±8.8%降至術后 35.1%±5.5%， 末次隨訪時 ODI 評分為 36.0%±4.8%。椎體前緣高度術前、術后、末次隨訪時分別為 63.1%±14.9%，79.4%±13.0%，78.0%±13.4%，椎體中緣高度術前、術后、末次隨訪時分

4、別為 58.0%±15.2%，79.0%±11.2%，78.7%±11.5%，椎體后緣高度術前、術后、末次隨訪時分別為86.4%±7.2%，91.9%±6.1%，90.1%±8.4%。Cobb 角由術前 16.4°±9.7°下降至術后11.6°±7.4°，末次隨訪時為 12.6°±9.0°

5、。椎管內骨塊占位率術前、術后及末次隨訪時分別為 26.3%±5.0%，26.0%±5.0%，19.6%±4.5%。 各項指標（VAS、ODI、椎體前、中、后緣高度，Cobb 角）術前與術后及術前與末次隨訪差異均有統(tǒng)計學意義（P0.05） 。椎管內骨塊占位率術前與術后差異無統(tǒng)計學意義（P>0.05） ，術前與末次III Kyphoplasty for the treatment of type-A3.1
