The behavior of the unfused lumbar curve was evaluated radiographically in 58 cases of adolescent idiopathic thoracic scoliosis that had a selective thoracic fusion only. The lumbar scoliosis echoed the correction obtained in the thoracic scoliosis both immediately postoperatively and at an average 2 1/2-year follow-up. In the sagittal plane, although correction was obtained in the thoracic hypokyphosis, there were no changes seen in the lumbar lordosis at final follow-up. Segmental instrumentation was more effective in correcting thoracic scoliosis and hypokyphosis, but did not alter the behavior of the lumbar curve. The caudal extent of the fusion relative to the stable vertebra did not measurably alter the operative results in either curve or plane.
对58例仅进行选择性胸椎融合的青少年特发性胸椎侧弯患者进行影像学评估，以观察未融合腰椎曲度的表现。腰椎侧弯在术后即刻以及平均2.5年的随访中，均与胸椎侧弯所获得的矫正情况相呼应。在矢状面，尽管胸椎后凸畸形得到了矫正，但在最终随访时腰椎前凸未见变化。节段性内固定在矫正胸椎侧弯和后凸畸形方面更有效，但并未改变腰椎曲度的表现。融合相对于稳定椎体的尾端范围，在曲线或平面上均未显著改变手术效果。
