case_images: L3 and L4 resulting in severe spinal canal stenosis, with no stenosis at L5-S1 [Figure 1]. Lumbar flexion and extension imaging demonstrated no evidence of increased subluxation despite the grade I spondylolisthesis. Due to a small left L4-L5 disc hernation on MRI [Figure 1b], a left L4-L5 microdiscectomy was performed as well.
