Status post thoracolumbar fusion. Signs and symptoms: See above. Nonenhanced CT of thoracolumbar spine:Examination demonstrates severely compressed L1 vertebral body with significant posterior protrusion of fractured vertebrae into the spinal canal. There is evidence of interval laminectomy at L1 and L2 levels. There is also evidence of posterior fixating rods and fusion utilizing transpedicular screws bilaterally at T11, T12, L2 and L3 levels. In comparison with prior MRI examination there is slight interval improvement in the alignment of vertebral column and good minimal residual anterolisthesis of T12 in respect to L2. There is no evidence of fracture of any of the rods or transpedicular screws. The appropriateness of their positioning should be decided by the referring physician. Note is made of a surgical drain extending posterior to the spinal canal in the lower thoracic and upper lumbar region. Examination also demonstrate mild compression fracture of the superior endplate of L3.
1.Severely compressed fracture of L1 vertebrae with significant extension posteriorly into the spinal canal.2.Interval bilateral laminectomy at L1 and L2 levels. 3.Posterior fixating rods and multilevel transpedicular bilateral screw placement of T11, T12, L2 and L3 levels.4.Mild residual anterolistheses of T12 with interval improvement since prior MRI exam.
