Condition
Degenerative Spondylolisthesis
Degenerative spondylolisthesis occurs when age-related disc and facet-joint wear allow one vertebra to slip forward relative to the one below it. Atlas can explain why this can create back pain, stenosis, or nerve symptoms and how Dr. Iyer decides when decompression alone is enough versus when stabilization should also be part of the plan.
What it is
This condition usually develops gradually in the lumbar spine when disc degeneration and facet-joint arthritis reduce the normal stability of a segment. The slip is often modest in size, but even a small shift can change the shape of the canal and foramina where nerves travel.
How it causes symptoms
Patients may have mechanical low back pain, leg pain, numbness, or symptoms of stenosis that worsen with standing and walking. Many people notice a combination of back-dominant pain and nerve-related leg symptoms because both instability and narrowing can be present at once.
How treatment starts
Initial care often includes therapy, medication, and sometimes injections, especially when symptoms are moderate and neurologic function is preserved. Flexion-based positions or exercises may provide temporary relief because they can reduce pressure on narrowed nerve spaces.
When surgery is considered
Surgery is more likely to be discussed when symptoms remain function-limiting or instability appears significant on imaging and exam. The decision between decompression alone and decompression with fusion depends on the amount of slip, the motion at that level, and the overall alignment of the spine.
