摘要
目的探讨腰椎滑脱患者脊柱在矢状面发生变化及骨盆排列变化。方法采用2011年1月-2012年9月该科腰椎真性滑脱25例病人全脊柱侧位(包括双侧髋关节)X线摄片上测脊柱矢状位指标:脊柱的矢状位垂直轴(S1与C7铅垂线C7PL距离,SVA)、胸后凸(thoracic kyphosis,TK)、腰前凸(lumbar lordosis,LL)和骨盆的形态参数:骨盆倾斜角(pelvic tilt,PT)、骶骨倾斜角(sacrum slop,SS)、骨盆投射角(pelvic incidence,PI)。结果该组25例病例中TK角度平均为37.0°(27°～58°),较文献报道正常值明显减小(P<0.05);LL角度平均为55.3°(38°～68°),较文献报道正常值明显增大(P<0.05);PI角度平均为61.6°(43°～82°),较文献报道正常值明显增大(P<0.05);PT角度平均为18.5°(9°～33°),较文献报道正常值明显增大(P<0.05);SS角度平均为43.1°(30°～53°),较文献报道正常值明显增大(P<0.05)。结论腰椎滑脱患者整个脊柱矢状位生物力线的失衡导致矢状位重新平衡以防止驼背及俯视,最终导致胸椎的曲度的减小、腰椎曲度的加大并且腰椎滑脱患者骨盆参数值增大,而这些变化使得胸腔容积、骨盆容积和腹腔容积的减小。
Objective To study sagittal plane changes and pelvic alignment change of lumbar spondylolisthesis patients. Methods From September 2011 to September 2012 in our department, the lateral standing radiographs of the spine and pelvis of 25 patients with developmental spondylolisthesis were analyzed by the measurement of the following parameters：thoracic kypbosis （TK）, lumbar lordosis（ LL）, pelvic tih（PT） ,sacrum slop（SS） ,pelvic incidence（PI）. Results Statistically significant differences（P 〈0.05） were found in TK,LL, FT, SS and PI between the spondylolisthesis and those reported in historical normal subjects,the mean TK（37.0 ± 6.3 ） was lower than those in normal subjects,while LL（55.3 ± 6.9）, PT（ 18.5 ±5.2）, SS（43.1 ± 5.1 ） and PI（61.6 ± 8.2） were much higher in subjects with spondylolisthesis than in those in normal subjects;a significant correlation was found（ Pearson＇ s bilateral test） between the following variables：PI and SS, PI and PT, PI and LL, SS and LL. Conclusions The whole spine sagittal biology force line imbalance leads to renewed sagittal balance, which eventually cause the of decrease thoracic spine curvature, increase in lumbar curvature and pelvic parameter value increase of lumbar spondylolisthesis patients.
