The spinal mobility and sagittal configuration in 96 scoliotic patients treated according to Harrington were investigated with a Debrunner kyphometer and a Myrin inclinometer. The more distal the fusion limit in the lumbar spine, the more reduced was the lumbar lordosis and flexion. The patients' own estimation of lumbar rigidity and pain, scored on visual analogue scales, increased as the fusion limit increased distally. The results for the thoracic spine's sagittal configuration and mobility were analogous but the trend was less pronounced. The patients' estimation of thoracic rigidity had little correlation with the number of segments fused. This study shows that fusion of the lumbar spine below L3 is to be avoided, except when specifically indicated. Furthermore, the study shows that the present technique does not adequately preserve the sagittal configuration of the thoracic and lumbar spine.
使用德布勒纳后凸计和米林倾角仪对96例接受哈灵顿手术治疗的脊柱侧弯患者的脊柱活动度和矢状位形态进行了研究。腰椎融合范围越靠下，腰椎前凸和前屈度降低越明显。患者根据视觉模拟量表对腰椎僵硬程度和疼痛程度的自我评估随着融合范围向下延伸而增加。胸椎矢状位形态和活动度的结果类似，但趋势不那么明显。患者对胸椎僵硬程度的评估与融合节段数相关性较小。本研究表明，除非有明确指征，应避免L3以下的腰椎融合。此外，该研究表明，目前的技术不能充分保留胸腰椎的矢状位形态。
