Evaluate sagittal balance, evaluate effusion. Back and right leg pain. History of lumbar fusion. Mild multilevel degenerative disc disease and anterior osteophytes are noted in the thoracolumbar spine. Posterior stabilization rods and pedicular screws entering the L4 and L5 vertebral bodies are noted, with intervertebral bone graft at L4-5. There remains approximately 7 mm in anterolisthesis of L4 on L5.There is approximately 11 degrees levoscoliosis of the thoracolumbar spine, as measured from the superior endplate of T3 to the inferior endplate of L1.Coronal balance is within normal limits. There is approximately 3.5 cm positive sagittal balance.
Multilevel degenerative disc disease.Levoscoliosis and positive sagittal balance of the spine, as above.
