Examination shows weakness of plantar flexion, leg extension, and toe flexion. There is no ankle reflect. Sensation is diminished on the posterior aspect of the leg and lateral foot.

This is an S1 lumbosacral radiculopathy, most commonly caused by disc herniation or spondylosis. The image shows an L5-S1 disc herniation in the setting of degenerative disc disease.
