BMD: − 5.7, VAS: 6 points, ODI: 75. T12 fracture with vertebral collapse, kyphosis deformity, RKA: 35.4°, SCCr: 54.8, AVHr: 25.9 (A, B). 3D CT of the spine showing a wedge-shaped collapse of the T12 with protruding bone blocks entering the spinal canal from the posterior wall (C). MRI of the thoracolumbar region shows significant compression of the spinal cord at T12 (D). Lumbar spine radiographs in both anteroposterior and lateral views. The patient underwent local laminectomy at T12 and spinal internal fixation at T10-L2, with some vertebral bodies reinforced with bone cement. Postoperative 1-week RKA: 21.7°, SCCr: 77.1, AVHr: 58.0 (E, F). Final follow-up, RKA: 25°, SCCr: 66.8, AVHr: 49.3 (K, L)
