High-grade (Grade III) Degenerative spondylolisthesis at L4/5 Treated Successfully by Transforaminal Interbody Fusion (TLIF): A Case Report

We report a rare case of High grade degenerative spondylolisthesis. Degenerative spondylolisthesis is not necessarily rare. However the degree of degenerative spondylolisthesis rarely exceeds Meyerding grade II. The patient 66 years old female present exceed Meyerding Grade III degenerative spondylolithesis with back pain and gait disturbance for over 20 years. Conservative treatment had no effect. Functional radiographs CT and MRI of the lumbar spine revealed the high grade slippage of L4/5 hypermobility and cauda equine was severe compressed. There was not spondylolysis at L4 lamina. The Bilateral facetectomy and partial reduction and transforaminal lumbar interbody fusion (TLIF) at L4/5 was performed, the back pain disappeared and her neurological deficit and activity of daily living ameliorated. There has not been any adjacent level degeneration after 4 years after TLIF operation.
