The effect of Harrington rod sagittal plane contouring, or lack of it, on total lumbar, segmental lumbar, and lumbosacral lordosis was studied retrospectively in a series of 36 patients operated on for idiopathic scoliosis. Regardless of contouring, there was a decrease in total lumbar lordosis and lordosis above L4, with an increase in lordosis below L5. Although not statistically significant, patients with contoured rods had less loss of segmental (L1-4) lordosis and less increase in segmental lumbosacral lordosis (L4-S1) than the noncontoured group. Although helpful, additional steps beyond concave rod contouring appear to be necessary to consistently preserve lumbar lordosis.
对36例因特发性脊柱侧弯接受手术的患者进行回顾性研究，探讨哈林顿棒矢状面塑形与否对腰椎整体、节段性腰椎及腰骶部前凸的影响。无论是否塑形，腰椎整体前凸及L4以上节段的前凸均减小，L5以下节段的前凸增加。尽管差异无统计学意义，但与未塑形组相比，使用塑形棒的患者节段性（L1 - 4）前凸丢失较少，节段性腰骶部前凸（L4 - S1）增加较少。尽管有帮助，但除了凹面棒塑形之外，似乎还需要采取其他措施来持续维持腰椎前凸。
