Following the trauma, his chest and back pain were not completely relieved, and he gradually developed kyphosis (Figure 1).

T12 vertebrae had become wedge-shaped and the patient had developed severe kyphosis (thoracolumbar cobb angle is 57 ). Three-dimensional CT (Figure 3) showed that the anterior edge of the T12 vertebral body was compressed to 3/4 of the normal range, the anterior and left hemivertebra showed a severely comminuted fracture, the right hemivertebra was transversely split, and the bilateral pedicle and accessory structures had flexion-distraction injuries (FDI).

Magnetic resonance imaging (Figure 4) showed fractures of T12, wedge-shaped vertebrae, and no apparent spinal cord compression.

One week after the operation, external observation images (Figure 5) were taken.

Re-examination of thoracolumbar x-rays (Figure 6) and thoracolumbar 3D CT (Figure 7) showed that the physiological curvature of thoracolumbar was restored(thoracolumbar cobb angle is 11 ), the fracture end of the right pedicle and posterior vertebral body of T12 was closed, and the left half of the vertebral body was well reconstructed.

A review of his thoracolumbar 3D CT (Figure 8) showed no significant changes in the physiological curvature of the thoracic vertebrae, good titanium cage positioning, continuous callus formation between adjacent vertebrae, and bony fusion of the fractured ends of the residual vertebrae.

Eighteen months after the operation, 3D CT of the thoracolumbar segment was reviewed (Figure 9) and showed that the titanium cage was surrounded by the callus and had fused with the adjacent vertebrae.
