Spinal stenosis is a degenerative condition that causes the narrowing of the spinal canal, leading to pressure on the spinal cord and nerves. This can result in various symptoms, including back or neck pain, tingling in the arms or legs, and in severe cases, difficulty controlling the bowel and bladder. While the condition can occur in any part of the spine, it is most commonly found in the lower back, known as lumbar spinal stenosis. A common symptom of spinal stenosis is muscle weakness, which can lead to disability. Studies have found a strong correlation between spinal stenosis and multifidus muscle atrophy, suggesting that the compression of nerve roots and degenerative changes may contribute to muscle atrophy.

Multifidus muscle atrophy and lumbar spinal stenosis
Spinal stenosis is the narrowing of the spinal canal, which can occur in any part of the spine but is most common in the lower back (lumbar area). This can cause pressure on the spinal cord or the nerves that lead to the muscles, resulting in pain and tingling in the arms or legs. Lumbar spinal stenosis can cause cauda equina syndrome, which requires immediate medical attention.
Multifidus muscles are small yet powerful triangular muscle bundles located on either side of the spinal column, stabilising the lumbar spine. The atrophy of these muscles has been strongly associated with low back pain (LBP), with an incidence of >80% in patients diagnosed with LBP.
Degenerative lumbar spinal stenosis (DLSS) is a common degenerative condition in older adults that can cause LBP. Muscle atrophy (MA) is a leading cause of muscle weakness and disability in individuals with spinal stenosis. A study investigated the correlation between MA and the grade of spinal stenosis in patients with DLSS. The severity of MA was found to positively correlate with the severity of spinal stenosis.
One possible explanation for the severe multifidus atrophy in the stenotic segments is that the compression of the nerve root in the stenotic segment may result in the atrophy of the multifidus muscle. Another possible explanation is that the inflammatory and immune responses produced during degeneration of the intervertebral disc will first affect the multifidus muscle. Although there is still controversy about the causal relationship between multifidus atrophy and spinal stenosis, multifidus atrophy has been demonstrated to strongly correlate with spinal stenosis.

The severity of spinal stenosis and muscle atrophy
Spinal stenosis is a narrowing of the spinal canal, which contains the spinal cord and its nerve branches. This condition can be congenital or acquired through degeneration of the joints in the spine. Spinal stenosis can lead to pressure on the spinal cord and nerves, causing a range of symptoms, including muscle atrophy.
Muscle atrophy is a common complication of spinal stenosis and is characterised by a loss of muscle mass and weakness. The severity of muscle atrophy in spinal stenosis patients has been the subject of several studies. One study found that the severity of multifidus atrophy was positively correlated with the severity of spinal stenosis. The multifidus muscles are a series of small but powerful triangular muscle bundles located on either side of the spinal column, stabilising the lumbar spine.
The study found that the symptomatic sides of the spine had more atrophic multifidus muscles than the contralateral sides. This indicates that the severity of muscle atrophy may be influenced by the specific region of the spine affected by stenosis. Another possible explanation for the severe multifidus atrophy in stenotic segments is the compression of the nerve root, which may result in the atrophy of the multifidus muscle.
The severity of muscle atrophy can be assessed through imaging techniques such as MRI scans, which can calculate the ratio of TFCSA to TCSA (TFCSA/TCSA). A smaller TFCSA/TCSA ratio indicates more severe muscle atrophy due to increased fat infiltration. This ratio was found to be smaller on the symptomatic sides of the spine, confirming the greater severity of atrophy in these regions.
In summary, spinal stenosis can lead to muscle atrophy, and the severity of atrophy is positively correlated with the severity of spinal stenosis. The side of the spine experiencing symptoms tends to exhibit more severe atrophy than the contralateral side. Treatment options for spinal stenosis and associated muscle atrophy include physical therapy, weight loss, medications, and in some cases, surgery.

Causes of spinal stenosis
Spinal stenosis is a condition characterised by the compression of nerve roots by several pathologic factors, leading to pain, weakness, and numbness. Spinal stenosis can be congenital (present from birth) or acquired. Congenital stenosis is caused by a small spinal canal, which can be attributed to conditions such as achondroplasia, osteopetrosis, apical vertebral wedging, and morquio syndrome. However, congenital cases are relatively rare, accounting for only about 9% of all spinal stenosis cases.
Acquired stenosis, which is far more common, is primarily caused by degenerative changes in the spine, including wear and tear, arthritis, and spondylosis. Osteoarthritis, a common contributor to acquired stenosis, causes the cartilage covering the facet joints between vertebrae to wear away, leading to bone-on-bone friction and the formation of bone spurs. These bone spurs protrude into the spinal canal, narrowing the space available for nerves. Thickened ligaments due to age and degenerative changes can also press against nerves or the spinal cord, contributing to spinal stenosis.
In addition to degenerative changes, acquired stenosis can also result from trauma, iatrogenic causes, and systemic processes. While spinal stenosis typically affects the lumbar (lower back) and cervical (upper neck) areas, it can also occur in the thoracic spine, usually due to disk herniation.

Diagnosis and treatment options
Spinal stenosis is typically diagnosed during a patient history and orthopedic exam. If spinal stenosis is suspected, an MRI or CT myelography can be ordered to confirm the diagnosis. X-rays of the lumbar spine may also be taken to look for bone growths that could be pushing on spinal nerves.
Treatment options for spinal stenosis depend on the location of the issue and the severity of the symptoms. For mild cases, at-home care may be recommended first. This can include applying heat or cold to the affected area, exercising, and maintaining good posture. Losing weight, quitting smoking, and learning how to safely lift heavy objects can also help.
If symptoms worsen or do not respond to at-home care, physical therapy may be recommended. Physical therapists can help patients develop an exercise program to strengthen the muscles supporting the spine and improve flexibility and balance. They can also teach patients how to walk in a way that opens up the spinal canal and eases pressure on the nerves.
Medications can also be used to treat spinal stenosis. Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) can help relieve inflammation and provide pain relief. Prescription medications with pain-relieving properties, such as antiseizure medication or tricyclic antidepressants, may also be recommended. Muscle relaxants may be prescribed for patients experiencing muscle cramps or spasms.
Injections and surgery are typically considered only if other treatment options have not worked. Steroid injections can be used to reduce inflammation, pain, and irritation around pinched spinal nerves. Laminectomy, or decompression surgery, is the most common type of surgery for spinal stenosis and involves removing a portion of the vertebra to create more room for the spinal cord and nerves.

Managing spinal stenosis
Spinal stenosis is the narrowing of the spinal canal, which puts pressure on the spinal cord and nerves, causing pain and other symptoms. While there is no cure for spinal stenosis, there are several treatment options available to help manage the condition and its symptoms.
Nonsurgical Treatments
Nonsurgical treatments are aimed at symptomatic relief and can include:
- Oral medications: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can help relieve inflammation and provide pain relief. Prescription medications with pain-relieving properties, such as antiseizure medications (e.g., gabapentin) or tricyclic antidepressants (e.g., amitriptyline), may also be recommended. Muscle relaxants may also be used to potentiate NSAID analgesia.
- Physical therapy: A physical therapist can help develop an exercise program to improve strength, balance, flexibility, and spine stability. Exercises such as bends, pelvic tilts, and standing squats can help ease symptoms and improve everyday function.
- Alternative treatments: Complementary and alternative treatments such as manipulation of the spine and nearby tissues may also help relieve pain.
Injections
Injections can be used to provide temporary pain relief and reduce inflammation. These include:
- Epidural steroid injections: Corticosteroids can be injected directly into the area around the spinal cord to reduce inflammation and pain.
- Nerve blocks: Anesthetics can be injected near the damaged nerves to provide relief.
- Facet injections: These injections may provide temporary relief from pain.
Surgery
Surgery is typically recommended when significant radiculopathy, myelopathy, neurogenic claudication, or incapacitating pain is present. Surgical procedures for spinal stenosis include:
- Laminoplasty: This procedure creates space in the spinal canal in the neck by placing a metal hinge on the lamina.
- Discectomy: The injured part of a bulging or herniated disc is removed to ease pressure on the nerves or spinal cord.
- Spinal fusion: Vertebrae are joined together to reduce movement within the spine.
- Foraminotomy: The portion of the vertebrae where nerve roots branch out is expanded.
- Minimally invasive surgery: Removes parts of the lamina or disc without damaging healthy tissue.
- Laminectomy: Removes part of the vertebra that is putting pressure on the nerve to relieve pressure and open up space.

Frequently asked questions
Spinal stenosis is the narrowing of one or more spaces within the spinal canal, which contains the spinal cord and its nerve branches. It can be congenital or acquired due to degeneration of the joints in the spine.
Spinal stenosis can cause back or neck pain, tingling in the arms or legs, and in more severe cases, trouble controlling the bowel and bladder. It may also lead to muscle weakness and disability.
Treatment options include at-home care, physical therapy, medications, injections, and surgery. The least invasive surgery involves placing an interspinous spacer device called "XSTOP" between the spinous processes to indirectly decompress the thickened ligaments of the spine.
While there is a strong correlation between spinal stenosis and muscle atrophy, the causal relationship is still a subject of controversy. One possible explanation is that the compression of the nerve root in the stenotic segment may result in the atrophy of the multifidus muscle.
