Development of a Three-Dimensional Finite Element Model of Thoracolumbar Kyphotic Deformity following Vertebral Column Decancellation

Figure 1

The full-length spine radiographs of a patient were obtained before surgery and one week after surgery. (a) Before surgery, the apical (kyphosis) vertebra was L1, with thoracolumbar kyphosis (T10 to L2) of 52°. The coronal Cobb angle between T9 and L3 was 56°. (b) Vertebral column decancellation was applied at L1, and the spine was fused from T10 to L4 with pedicle screws and a rod system. The thoracolumbar kyphosis and scoliosis were corrected to 11° and 12°, respectively.
