Diagnosis
Her pre-operative MRI revealed a scoliotic deformity. At L5-S1 she had a large foraminal disc herniation on the left side at L5-S1, which obliterated the neural foramen and compressed the left L5 nerve root.
She was diagnosed with scoliosis and a lumbar herniated disc causing an L5 sciatica / radiculopathy (pain) due to the severe neuroforaminal stenosis (narrowing) at L5-S1 and compression of the exiting L5 nerve root.
Selected Treatment
The patient underwent a T10 to S1 posterior spinal fusion with scoliosis correction and left sided L5-S1 nerve decompression with Transforaminal Lumbar Interbody Fusion (TLIF).
This procedure allowed for improved sagittal and coronal alignment and created more space for the L5 nerve root to exit the spine without being impinged.
