This retrospective study evaluates lumbar lordosis in 43 patients before and after Harrington instrumentation into the lumbar spine. The authors measured overall lumbar lordosis, lordosis of unfused lumbar levels, and sagittal vertical axis. Lordosis decreased progressively in lower levels of fusion. The increase in lordosis below the fusion did not compensate for the overall loss of lordosis. The sagittal vertical axis moved forward, producing a subtle, asymptomatic form of flat back syndrome.
这项回顾性研究评估了43例患者在腰椎进行哈林顿器械固定术前后的腰椎前凸情况。作者测量了整体腰椎前凸、未融合腰椎节段的前凸以及矢状垂直轴。融合较低节段的前凸逐渐减小。融合节段以下前凸的增加并不能弥补整体前凸的丧失。矢状垂直轴向前移动，产生了一种轻微的、无症状的平背综合征形式。
