后路选择性内固定矫形治疗青少年特发性脊柱侧凸

目的 评价经后路选择性关键椎体内固定矫形治疗青少年特发性脊柱侧凸（AIS）的临床疗效，探讨其手术适应证。方法经后路选择性关键椎体内固定矫形治疗的131例青少年AIS患者，术前均进行详细的临床和影像学检查评估，按影像学资料确定主侧凸顶椎、端椎、中立椎、稳定椎等关键椎体，并拟定关键椎体椎弓根螺钉内固定。结果主侧凸Cobb角由术前的平均51．3°±12．9°矫正至术后的平均8．9°±4．5°。131例均获得随访，时间8～52个月，末次随访时主侧凸Cobb角平均丢失4．6°±1．2°，椎弓根螺钉松动1例，未发现椎弓根螺钉及棒的断裂。结论经后路选择性关键椎体内固定矫形治疗青少年AIS可取得良好的临床疗效，减少患者医疗费用，符合我国实际国情，但术前应做好适应证选择。
