AIS: 矫形手术中近端固定椎的选择与术后肩部平衡
专题主持:邱勇教授
青少年特发性脊柱侧凸(adolescentidiopathic scoliosis, AIS)患者术后双肩平衡与否是评估手术疗效和影响患者满意度的重要指标之一【1-2】。由于肩部平衡与上胸弯的关系密切,因此正确处理上胸弯以及合理选择融合近端固定椎是重建术后肩关节平衡的关键因素【3-4】。为保证术后肩部平衡,早期的研究主要集中于如何正确识别结构性上胸弯上,但上胸弯的结构性质与肩部平衡与否并不完全一致,而且目前对于结构性上胸弯的认定及上胸弯融合指征的选择具有很大争议性。因此,学者们逐渐倾向于将术前肩部平衡情况作为独立的因素进行分析,来制定胸弯融合策略。术后是否发生双肩失平衡,取决于术前双肩平衡情况及上胸弯、主胸弯的矫正程度【5-7】。但目前如何确定近端固定椎的位置以及术后依据什么标准去评价效果尚存较大争议【8-10】。因此如何根据不同的侧弯分型及术前双肩平衡情况选择合理的近端融合椎是我们目前面临的挑战之一。
