矢状面畸形校正计划和预期结果。橙色(a)近端胫骨轴(线)成立通过定义胫骨高原(红线)和传输机械尾侧正常胫骨近端胫骨角度测量指标(63°;胫骨平台角度(TPA) 27°)和定位这个角度扩展向近端穿过胫骨元老。胫骨远端机械轴(黄绿色线)估计基于位置这条线从岩屑向近端延长正常,对侧肢体。定义这两个轴的交点测角的中性旋转中心(科拉)。横向平分线(紫色虚线),这是一个通过中立的科拉和位于等距(78°)从近端和远端胫骨轴,是画的。开放科拉位于颅横向平分线顶点的胫骨粗隆(大黑点),被选为铰链轴的位置。(b)径向截骨术是计划在该地区的近端胫骨metaphyseal-diaphyseal结。分心会导致旋转铰链轴的近端胫骨段(红色箭头)和分离的颅和尾胫骨皮质截骨术肢段的利润导致延长TPA是顺序减少到7°。定位上的铰链轴横向平分线是为了减少TPA和执行延长诱导二次转化畸形。 During distraction the position of the tibial eminences, which were used as the proximal landmark to define the mechanical tibial axis, were translated slightly cranial which also translated the final mechanical tibial axis (forest green line) cranial. (c) Regenerate bone (orange stippled area) would form in the distraction gap establishing a confluent column of tibial bone.
