Sequential correction: a reliable and simple technique for complex spine deformity

Based on the coronal balance classification for adult spinal deformity established by our center, a new surgical technique for adult spinal deformity was further proposed, namely Sequential Correction. Spine deformity was classified as thoracolumbar/lumbar type and lumbosacral type according to the driver of the deformity. A short rod was firstly installed to correct the driver, followed by another short rod installed on the other side, and two long rods were installed at last. The incidence of postoperative coronal imbalance was significantly reduced using sequential correction, and the correction rate was significantly improved compared with the traditional technique.
