摘要
目的探讨置钉密度是否影响Lenk1型青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)患者冠状位和矢状位矫正效果。方法回顾性分析2008年1月至2010年1月,在同一中心手术治疗的31例采用后路全钉选择性融合的Lenke1型AIS患者术前、术后即刻和术后2年随访结果。记录患者的一般资料。采用Pearson相关分析置钉密度与冠状位Cobb’s角矫正率及矫正比率的关系,置钉密度与冠状面术后2年随访矫正角度丢失及矢状位角度变化的相关关系。根据置钉密度的高低将患者分为高密度组(>0.7)与低密度组(≤0.7),统计比较两组间相关参数的差异。结果术前平均年龄为15.3岁,术前主胸弯角度平均为(48.5±8.5)°,术后2周随访平均矫正至(16.0±6.9)°,冠状位平均矫正率为68%;手术即刻矫正率与植入螺钉密度的相关性为-0.19(P=0.315),矫正比率与植入螺钉密度的相关性为-0.10(P=0.589),冠状位矫正角度丢失与植入螺钉密度的相关性为-0.04(P=0.837);矢状位胸椎后凸术后角度减少与置钉密度相关性0.09(P=0.619)。高、低置钉密度两组平均植入物密度分别为0.85与0.61(P<0.01),其它参数两组间差异无统计学意义。结论无论是否考虑柔韧性因素,Lenke1型AIS胸弯冠状面矫正率与置钉密度无明显相关性,矢状位胸弯生理曲度的变化与置钉比例无关。冠状面矫正角度2年丢失及矢状位角度变化与置钉密度也无关。
