From the material and data reviewed in our study of 405 patients, it appears that postoperative correction of the thoracic spine approximately equals the correction noted on preoperative side-bending roentgenograms. Selective thoracic fusion can be safely performed on a Type-II curve of less than 80 degrees, but care must be taken to use the vertebra that is neutral and stable so that the lower level of the fusion is centered over the sacrum. The lumbar curve spontaneously corrects to balance the thoracic curve when selective thoracic fusion is performed and the lower level of fusion is properly selected. In Type-III, IV, and V thoracic curves the lower level of fusion should be centered over the sacrum to achieve a balanced, stable spine.
从我们对405例患者的研究中所回顾的材料和数据来看，胸椎术后矫正似乎大致等同于术前侧弯X线片上所记录的矫正情况。对于小于80度的II型曲线可安全地进行选择性胸椎融合术，但必须注意选用中立且稳定的椎体，以使融合的较低水平位于骶骨中心上方。当进行选择性胸椎融合术且正确选择融合的较低水平时，腰椎曲线会自发矫正以平衡胸椎曲线。在III型、IV型和V型胸椎曲线中，融合的较低水平应位于骶骨中心上方，以实现脊柱的平衡和稳定。
