Lysis Or Listhesis
Grade 1 is mild (20% slippage), while grade 4 is severe (100% slippage).
Symptoms can vary depending on whether the slippage is enough to pinch the nerve roots (the portion of the nerve that leaves the spinal cord to connect to other parts of the body) that go from the spinal cord to other parts of the body.
The discs and ligaments hold the vertebrae together, forming stable strong joints that allow slight movement between the vertebrae with the disc also functioning as a shock absorber.
As all people age the spine will experience decreased back support due to degenerative changes to the spine.
Risk factors that increase the risk of spondylolysis developing into spondylolisthesis include: The presentation of spondylolisthesis varies slightly by type although common symptoms include exercise-related back pain, radiating to the lower thighs, which tends to be eased by rest, particularly in positions of spinal flexion.
In degenerative spondylolisthesis this will relate in part to the progress and prognosis of the underlying changes. First one said maybe a nerve sheath tumour and advised mri with contrast.
The slippage often occurs as a result of bone fractures.

The two main causes are from either a stress fracture in the vertebra called is when one vertebra slides off another vertebra in both the coronal (front to back) and axial planes (top to bottom).
Due to the effects of gravity, certain severe cases of scoliosis can degenerate and become lateral listhesis.
