【摘要】:目的:評估退行性脊柱側凸畸形患者術前脊柱后方肌群肌力對長節(jié)段固定融合糾正矢狀位失衡效果的影響。方法:回顧性研究2014年1月~2015年10月于我院接受長節(jié)段固定融合手術的退行性脊柱側凸畸形患者32例。于術前對所有患者進行腰背肌力量測試,將可完成"小燕飛"動作的12例患者分為A組,年齡55~73歲(65.2±4.7歲);將無法完成"小燕飛"動作的20例患者分為B組,年齡55~75歲(64.8±4.9歲)。隨訪1.3~2年(1.5±0.5年)。比較兩組術前、術后即刻及末次隨訪時矢狀位影像學參數(shù)[腰椎前凸角(lumbar lordosis,LL)、胸椎后凸角(thoracic kyphosis,TK)、胸腰段后凸角(thoracic lumbar kyphosis,TLK)、骨盆傾斜角(pelvic tilt,PT)、骶骨傾斜角(sacral slope,SS)、矢狀位垂直偏距(sagittal vertical axis,SVA)、近端交界區(qū)后凸角(proximal junctional angle,PJA)等]以及臨床功能評分[Oswestry功能障礙指數(shù)(ODI)、JOA評分和腰背痛VAS評分]。結果:兩組患者的年齡、手術時長、術中出血量及平均住院日均無統(tǒng)計學差異,具有可比性。術前A組的LL、TLK、TK、SVA、PT、PI、SS、ODI、腰背痛VAS評分、JOA評分為29.6°±3.2°、33.5°±4.6°、54.6°±5.1°、9.9±2.1cm、28°±2.4°、54.8°±4.1°、26°±3.7°、(75.4±3.5)%、7.3±0.9分、8.7±0.5分;B組為29.7°±3.6°、35.3°±3.8°、55.2°±3.7°、9.4±1.6cm、28°±1.6°、52.2°±1.7°、23.4°±2.9°、(76.4±2.2)%、7.2±0.7分、8.5±0.5分。術后即刻A組的LL、TLK、TK、SVA、PJA、PT、SS、ODI、腰背痛VAS評分、JOA評分為41.5°±4.1°、8.8°±3.6°、25.8°±2.1°、3.6±1.0cm、3.6°±1.1°、14.8°±1.2°、40.8°±2.5°、(21.9±2.3)%、2.4±0.7分、23.2±1.4分;B組為40.6°±2.2°、10.1°±3.2°、27.3°±1.9°、3.5±1.0cm、3.8°±1.1°、16.9°±2.3°、35.3°±2.7°、(20.3±2.2)%、2.9±0.6分、23.0±1.3分;末次隨訪時A組為43.6°±4.3°、10.8°±3.6°、28.7°±1.8°、4.8±1.0cm、4.4°±1.5°、15.8°±1.2°、41.8°±2.7°、(14.5±5.1)%、2.0±1.6分、24.7±0.7分;B組為43.2°±2.0°、18.6°±3.2°、38.4°±3.2°、8.7±1.6cm、8.3°±2.6°、23.6°±2.6°、9.1°±3.3°、(28.7±3.2)%、4.6±1.7分、24.0±1.0分。兩組術前和術后即刻的矢狀位參數(shù)以及功能評分無統(tǒng)計學差異(P0.05);末次隨訪時兩組LL無顯著性差異(P0.05),TK、TLK、PT、SS、SVA、PJA均有統(tǒng)計學差異(P0.05),B組3例出現(xiàn)近端交界性后凸(proximal junctional kyphosis,PJK)。末次隨訪時兩組ODI、腿痛VAS評分有統(tǒng)計學差異(P0.05),A組優(yōu)于B組;JOA評分無統(tǒng)計學差異(P0.05)。結論:術前脊柱后方肌群肌力對退行性脊柱側凸畸形長節(jié)段固定術后矢狀位糾正起到重要作用,術前良好的腰背肌力量可減少長節(jié)段固定術后矢狀位糾正的丟失,從而降低交界性后凸等并發(fā)癥的發(fā)生率。
