What It Is

Lumbar spinal stenosis is a condition where the spinal canal, or one of the openings where the nerves leave the spine (the vertebral foramina), becomes narrow. If the narrowing is significant, the spinal nerves can become compressed, causing the symptoms of lumbar spinal stenosis, such as buttock pain, lower back pain, numbness and leg pain. These often get worse when walking or standing and better when sitting or bending forward (American Academy of Orthopaedic Surgeons, n.d.; Sherwood Forest Hospitals NHS Foundation Trust, 2025).

Spinal stenosis can happen in the neck, middle back or lower back, but it is most common in the lower back, which is what lumbar spinal stenosis refers to (Sherwood Forest Hospitals NHS Foundation Trust, 2025). It can be painful and can affect your quality of life, but it is not usually serious, and most people manage well over time (Sherwood Forest Hospitals NHS Foundation Trust, 2025).

At the bottom of the spinal cord is a bundle of nerves called the cauda equina (horse's tail), and severe compression here is rare but serious. This is called cauda equina syndrome and is a medical emergency (American Academy of Orthopaedic Surgeons, n.d.).

Lumbar Spinal Stenosis Anatomy

The spinal cord runs from your brain down to your lower back. It is the main communication pathway in the body, and from it run the nerves that control virtually every action your body needs for living. The spinal cord and nerves run through a series of holes in each vertebra that together form a canal called the spinal canal. Some people are born with a narrower spinal canal, so are more prone to spinal stenosis (American Academy of Orthopaedic Surgeons, n.d.; Sherwood Forest Hospitals NHS Foundation Trust, 2025). In most people, the canal gets narrower with age, as wear-and-tear changes (arthritis) in the discs and joints of the spine leave less room for the nerves; arthritis is the most common cause (American Academy of Orthopaedic Surgeons, n.d.; Sherwood Forest Hospitals NHS Foundation Trust, 2025). Changes in the position of the vertebrae, such as slippage of a vertebra, and disc problems such as a large disc prolapse can also narrow the spinal canal. Rarer causes include a growth such as a tumour or cyst.
