Yes. Adult scoliosis can be linked to spinal stenosis, a narrowing of the spaces around the spinal cord or nerves. The two conditions may develop together as age-related changes affect the spine, and a curve can also contribute to pressure on nerves. Not everyone with scoliosis has stenosis or symptoms. A clinician considers symptoms and imaging to understand whether the conditions are connected.
How Are Adult Scoliosis and Spinal Stenosis Connected?
Adult scoliosis is a sideways curve of the spine that may have started during childhood or developed later in life. When scoliosis develops in adulthood, it is often associated with changes in the discs and joints that support the spine. Spinal stenosis occurs when the space available for the spinal cord or spinal nerves becomes narrower.
According to UChicago Medicine, adult degenerative scoliosis is often accompanied by spinal stenosis and nerve compression. These problems can occur together because changes in the spine affect its shape and the space available for nerves. However, having an abnormal spinal curve does not automatically mean that nerve compression is present.
Age-related wear and tear may contribute to both conditions. As spinal discs lose height and joints develop arthritis, the spine can become less stable and its alignment may change. Bone spurs and thickened ligaments can also reduce the space around nerves. MedlinePlus identifies scoliosis and arthritis among conditions that can contribute to spinal stenosis.
Can Scoliosis Make Spinal Stenosis Worse?
In some adults, the shape and rotation of a scoliotic spine can affect the openings through which nerves leave the spinal column. Degenerative changes may narrow these openings further, putting pressure on nearby nerve roots. Narrowing can also occur within the central spinal canal, where the spinal cord or nerve structures pass.
The effect depends on the location of the curve, the areas of narrowing, and whether the nerves are affected. Some people have noticeable scoliosis on an X-ray but little discomfort. Others experience back pain, leg symptoms, or difficulty walking when stenosis and nerve compression are also present. The degree of spinal curvature alone does not establish how much nerve pressure exists.
What Symptoms Can Occur When Both Conditions Are Present?
Adult scoliosis and spinal stenosis can cause overlapping symptoms, which can make the source of discomfort difficult to identify without an assessment. The following are examples of symptoms that may occur when spinal nerves are affected:
- Lower back pain or stiffness, particularly during standing or movement.
- Pain that travels from the lower back or buttocks into one or both legs.
- Tingling, numbness, burning sensations, or weakness in the legs or feet.
- A feeling of heaviness in the legs or reduced walking distance.
- Symptoms that become more noticeable during standing or walking and ease when sitting or leaning forward.
- Changes in posture, such as leaning forward or having difficulty standing upright comfortably.
Mayo Clinic notes that lumbar spinal stenosis may cause leg pain, cramping, numbness, or weakness, with symptoms often changing according to posture and activity. These patterns can help guide an evaluation, but they do not confirm that stenosis is responsible for a person's symptoms.
Scoliosis may also cause back discomfort or changes in posture without significant nerve compression. Conversely, nerve-related symptoms may occur even when the spinal curve does not appear especially pronounced. The timing of symptoms, how they affect everyday activities, and the findings on examination help clinicians distinguish between these possibilities.
How Do Doctors Determine Whether Scoliosis Is Linked to Stenosis?
Evaluation usually begins with a review of medical history and symptoms, followed by a physical examination. A healthcare professional may ask when the discomfort began, whether it affects one or both legs, what makes it worse, and whether walking or standing has become more difficult. The examination may include an assessment of posture, movement, walking, muscle strength, sensation, and reflexes.
Imaging tests can help establish whether a spinal curve and narrowing are present in the same region. According to the American Academy of Orthopaedic Surgeons, X-rays can show changes in spinal bones and alignment, while magnetic resonance imaging (MRI) helps show discs, ligaments, nerves, and the spinal cord. A CT scan may be useful when more detailed views of bone are needed or an MRI is unsuitable.
These tests provide different kinds of information. X-rays can help measure the curve and assess alignment, whereas MRI can show whether the spinal canal or nerve openings are narrowed and whether nearby nerves may be compressed. Clinicians interpret these findings alongside symptoms and examination results because an imaging abnormality does not necessarily explain every symptom.
What Treatment Options May Help?
Treatment depends on the symptoms, the location and extent of stenosis, the spinal alignment, and how much daily activity is affected. The goal may be to reduce pain, improve walking and movement, maintain function, or relieve pressure on nerves. A spinal curve by itself does not mean surgery is necessary.
Nonsurgical care
Many adults begin with nonsurgical treatment. Depending on their needs, a care plan may include physical therapy, exercises selected for strength and flexibility, adjustments to activities that aggravate symptoms, and medication when appropriate. Some people may be offered an injection around irritated nerves to help relieve pain. The benefits and risks of medicines and injections should be discussed with a healthcare professional.
Mayo Clinic's guidance on spinal stenosis treatment describes physical therapy, medicines, injections, and surgery as possible options, depending on the person's condition. Nonsurgical treatments may improve symptoms and function, but they do not necessarily reverse the underlying narrowing.
When might surgery be considered?
Surgery may be discussed when symptoms remain disabling despite nonsurgical care, walking becomes substantially limited, or nerve compression causes significant weakness or other concerning problems. One procedure, called decompression, removes or reduces tissue that is pressing on nerves to create more space. In selected cases, spinal fusion may also be considered to stabilize the spine, particularly when instability or deformity affects the surgical plan.
When scoliosis and stenosis occur together, the surgical approach may need to address both nerve pressure and spinal alignment. The appropriate procedure depends on the location of the narrowing, the shape and stability of the spine, overall health, and the expected benefits and risks. Surgery is not required for everyone with either condition.
When Should You Seek Medical Attention?
Arrange a medical assessment if back or leg symptoms persist, worsen, interfere with daily activities, or are accompanied by new numbness, weakness, or difficulty walking. A clinician can determine whether scoliosis, spinal stenosis, another spinal condition, or a combination of factors may be contributing.
Seek emergency medical care if you develop new loss of bladder or bowel control, difficulty passing urine, numbness around the groin or inner thighs, or rapidly worsening leg weakness. These symptoms can indicate severe pressure on nerves in the lower spine, including a rare emergency called cauda equina syndrome. Prompt assessment is essential.
Adult scoliosis and spinal stenosis can be related, particularly when age-related changes affect spinal alignment and narrow the space around nerves. Understanding which changes are present and how they relate to symptoms helps guide a treatment plan suited to the person's needs.
