Diagnosis
She was diagnosed with a L4-5 grade 1 degenerative spondylolisthesis with facet arthritis and mild-to-moderate spinal stenosis.
Her pre-operative MRI showed: Severe L4-5 foraminal stenosis resulting in compression of the exiting L4 nerve root and sciatica. It also showed L4-5 Spinal Stenosis and facet joint arthritis with fluid in the right facet joint.
Selected Treatment
The patient underwent a minimally invasive Transforaminal Lumbar Interbody Fusion (TLIF) and Laminectomy. The Minimally Invasive TLIF was performed with central interbody cage placement. A Minimally Invasive Laminectomy was also performed to decompress the stenosis.
As shown above the MIS TLIF and Laminectomy are performed through a tubular retractor 22-26mm in diameter. This procedure allowed for reduction of the slippage at L4-L5 and realignment of the spine. It also allowed for decompression L4-5 neuroforaminal stenosis so that there was space created for the exiting L4 nerve root.
