  Spinal stenosis can be caused by congenital or acquired etiologies. Only 9% of the cases result from congenital etiologies. Some common congenital causes include achondroplasia, shortened pedicles, osteopetrosis, apical vertebral wedging, spinal dysraphism, segmentation failure early vertebral arch ossification, thoracolumbar kyphosis, morquio syndrome, and osseous exostosis. […] Acquired stenosis occurs primarily from trauma, degenerative changes, iatrogenic causes, and systemic processes. Trauma usually affects the vertebral canal acutely with a mechanical force. Degenerative changes occur when there is a narrowing of the central canal and lateral recess from posterior disk herniation, ligamentum flavum hypertrophy, and spondylolisthesis. Laminectomy, fusion, and discectomy surgeries can cause iatrogenic spinal stenosis.

  https://www.mayoclinic.org/diseases-conditions/spinal-stenosis/symptoms-causes/syc-20352961

  Spinal stenosis happens when the space inside the backbone is too small. […] The most common cause of spinal stenosis is wear-and-tear damage in the spine related to arthritis. […] As the spine ages, bone spurs or herniated disks are more likely to happen. These problems can shrink the amount of space available for the spinal cord and the nerves that branch off of it. […] Some people are born with a small spinal canal. But most spinal stenosis occurs when something happens to reduce the amount of open space within the spine. Causes of spinal stenosis include: […] Bone spurs. Wear-and-tear damage from arthritis can cause extra bone to grow on the spine. This creates bone spurs that can push into the spinal canal. […] Herniated disks. Disks are the soft cushions that act as shock absorbers between the spinal bones. If part of the disk’s soft inner material leaks out, it can press on the spinal cord or nerves.

  Pagets disease. With this condition, your bones grow abnormally large and brittle. This results in a narrowing of the spinal canal and nerve problems. […] Thickened ligaments. When the cords that hold your bones together get stiff and thick, they can bulge into your spinal canal and make it smaller. […] The main risk factor for spinal stenosis is being over 50. Women (and those assigned female at birth) as well as people who’ve had spinal surgery are at higher risk. […] Some people are born with spinal stenosis or diseases that lead to it, such as scoliosis (curvature of the spine). For them, the condition usually starts to cause problems between the ages of 30 and 50. An injury to your spine can also put you at risk for stenosis at a younger age.

[…] But people with other types of arthritis and related conditions that affect the spine may develop spinal stenosis. […] Younger people with a spine injury or a narrow spinal canal or people with scoliosis (an abnormal curve of the spine) are also at risk. […] A back or neck injury, a spinal tumor or having too much fluoride or calcium in the body can also make someone more likely to develop spinal stenosis.

• #1 Spinal Stenosis: What It Is, Causes, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/17499-spinal-stenosis

  Spinal stenosis has several causes. Many different changes or injuries in your spine can cause a narrowing of your spinal canal. The causes are split into two main groups: […] Acquired spinal stenosis is more common. It usually happens from wear and tear changes that naturally occur in your spine as you age. Only 9% of cases result from congenital causes. […] Causes of acquired spinal stenosis include: Bone overgrowth: Osteoarthritis is the wear and tear condition that breaks down the cartilage in your joints, including your spine. […] Acquired spinal stenosis means you develop it later in life (after birth) most commonly after the age of 50. These cases usually happen from an injury or changes in your spine that occur as you age (degenerative changes). […] Congenital spinal stenosis affects babies and children. It can happen due to: Issues with spine formation during fetal development.

• #1 Lumbar Spinal Stenosis – OrthoInfo – AAOS

  https://orthoinfo.aaos.org/en/diseases–conditions/lumbar-spinal-stenosis/

  Lumbar spinal stenosis is a common cause of low back and leg pain, or sciatica. […] As we age, the normal wear-and-tear effects of aging can lead to narrowing of the spinal canal, which houses the spinal nerves and spinal cord. This condition is called spinal stenosis. […] Degenerative changes of the spine are seen in up to 95% of people by the age of 50. Spinal stenosis most often occurs in adults over 60. […] A small number of people are born with back problems that develop into lumbar spinal stenosis. This is known as congenital spinal stenosis. […] Arthritis is the most common cause of spinal stenosis. Arthritis refers to degeneration of any joint in the body. […] In the spine, arthritis can result as the disk degenerates and loses water content. […] As the spine settles, two things occur. First, stress is transferred to the facet joints. Second, the tunnels through which the nerves exit (the foramen) become smaller. […] As the facet joints experience increased pressure, they also begin to degenerate and develop arthritis, similar to that occurring in the hip or knee joint. […] The combination of bone spurs and thickened ligaments crowds the space for the nerves, resulting in stenosis.

  https://mayfieldclinic.com/pe-sten.htm

  Spinal stenosis is a degenerative condition that happens gradually over time and refers to: narrowing of the spinal and nerve root canals […] Stenosis can also be caused by other degenerative conditions such as spondylosis or spondylolisthesis; traumatic injury, vertebral fracture, and dislocation; skeletal conditions such as rheumatoid arthritis or ankylosing spondylitis; or metabolic conditions such as Paget’s disease or fluorosis, an excessive level of fluoride in the body. […] Osteoarthritis is the most common cause of spinal stenosis. The cushioning disc between your vertebrae dries out and shrinks. You lose bone mass. Bone spurs develop. Your facet joints can enlarge because of strain and stress. This is the body’s attempt to spread stress over a larger area. The larger a facet joint becomes, the less space is available for the spinal nerve as it exits the nerve root canal.

• #1 Lumbar Spinal Stenosis Causes and Diagnosis

  https://www.spine-health.com/conditions/spinal-stenosis/lumbar-spinal-stenosis-causes-and-diagnosis

  Degenerative changes in the spinal tissues associated with aging result in the vast majority of lumbar spinal stenosis diagnoses. […] Aging-related degeneration may affect the spinal joints, ligaments, and/or the intervertebral discs, causing the following changes: […] Arthritic degeneration may cause the facet joints to become arthritic and grow bone spurs (overgrown bone) that may impinge on spinal nerve roots and/or the spinal cord. […] Thickening of the short bands of ligament that connects the inner surface of the spinal canal may compress the spinal cord. […] Degeneration can cause a decrease in the height of intervertebral discs, reducing the disc space and narrowing the bony openings for spinal nerves (intervertebral foramen). […] Age-related degeneration may cause spinal instability, leading to vertebral body slippage. […] Rarely, tumors may compress the spinal cord or cauda equina. […] The risk of lumbar spinal stenosis typically increases with age. Risk factors also include genetic predisposition, being overweight, and occupations involving heavy physical labor.

  Lumbar spinal stenosis occurs when the space around the spinal cord narrows. This puts pressure on the cord and nerves that travel through the lower back into the legs. It is due to various causes such as spinal discs becoming less spongy with age or the growth of bone spurs, among others. […] Arthritis, or degeneration of a joint, is the most common cause of spinal stenosis. […] As the water content in our discs dry out with age, this leads to settling, or collapse, of the disc spaces and loss of disc space height. As a result, there is increased pressure on the facet joints and the protective layer of cartilage gets worn away. […] Other factors that contribute to lumbar spinal stenosis include: Bony growths or bone spurs, which form in response to the wear and tear from osteoarthritis, which grow into the spinal canal. A condition called Pagets disease can also lead to bony growths. Herniated discs when discs crack, allowing its contents to escape and press on the spinal cord. Thickening of ligaments, which happens over time, can bulge and intrude on the spinal canal. Abnormal growths in the spinal cord, including cancer though this is rare. Spinal injuries from accidents and other forms of trauma such as dislocations or fractures, and swelling that accompanies such injuries. […] You face a higher risk of developing lumbar spinal stenosis if you: Are a woman, Are born with a narrow spinal canal, Are older than 50 years, Have had a past injury to the spine, Have a congenital or genetic disease that affects bone and muscle development.

• #1 5 Causes of Spinal Stenosis | Integrity Spine & Orthopedics

  https://www.integrityspineortho.com/post/5-causes-of-spinal-stenosis/

  Spinal stenosis is narrowing of the open spaces within the spine. Narrowing can occur in the vertebral passageway that protects the spinal cord or in the bony passageways where spinal nerves exit the spine and travel to other areas of the body. […] Some people with spinal stenosis are born with a small spinal canal. But in most cases, spinal stenosis develops when degenerative changes narrow the open spaces within the spine. Below are 5 of the primary factors that contribute to spinal narrowing: […] Osteoarthritis. In the spine, osteoarthritis affects the facet joints that connect adjacent vertebrae. […] Herniated disc. Disc herniation occurs when a spinal disc tears or ruptures, causing the discs inner, jelly-like material to leak into the spinal canal. […] Degenerative disc disease. As we age, our spinal discs naturally deteriorate. […] Thickened ligaments. Age and degenerative changes from arthritis cause the ligaments that support vertebrae to become thicker and stiffer over time. […] Spinal deformity. A spinal deformity like scoliosis increases the risk of developing spinal narrowing.

• #1 Spinal Stenosis Risk Factors | MVMT Physio & Chiro

  https://stalbertphysiotherapy.com/spinal-stenosis-risk-factors/

  Spinal stenosis is a condition where the spinal canal starts to narrow. The narrowing causes pain and a host of other problems. […] Many medical professionals relate spinal stenosis with aging, especially people in their 50s. As we age, our bones undergo changes such as thickening ligaments, bone spurs, bulging or herniated discs, and compression fractures in the spine. All these are risk factors of spinal stenosis. […] Injuries Falls where your back hits a hard surface that could fracture and damage your spine. Inflammation arising from that injury can narrow and tighten the spinal canal. […] Tumors Cancerous growths can occur and grow inside your spine, thus narrowing the spinal canal and increasing likelihood of stenosis. […] Genetics Those born with structural deformities in their spine also have the tendency of the spinal canal to narrow, and thus lead to spinal stenosis. Other spinal stenosis risk factors associated with genetics are inherited conditions like Pagets disease.

• #1 What Causes Spinal Stenosis? | Premia Spine

  https://premiaspine.com/what-causes-spinal-stenosis/

  Spinal stenosis is a common source of chronic back pain. It develops when the spinal canal narrows, often due to age-related changes in the spine. […] You develop spinal stenosis either from age-related wear and tear on the spine or genetic factors. The former is known as degenerative spinal stenosis, and the latter is known as congenital spinal stenosis. […] The main cause of spinal stenosis is age-related spinal changes. More specifically, osteoarthritis is the primary cause of this spinal condition. Osteoarthritis develops gradually as people age, causing joint inflammation from the breakdown of protective cartilage. […] Both physical and psychological stress can cause spinal stenosis. Physical stress gradually contributes to spinal degeneration, which can lead to spinal stenosis. However, people often overlook the fact that psychological stress can also trigger spinal stenosis, for a few different reasons.

• #1 Spinal Stenosis Risk Factors | MVMT Physio & Chiro

  https://stalbertphysiotherapy.com/spinal-stenosis-risk-factors/

  Aside from age and genetics, another risk factor for spinal stenosis is lifestyle. […] A diet without the necessary nutrients for proper bone growth and regeneration can lead to spinal stenosis. Being obese is also another risk factor as the additional weight subjects the spine and vertebrae to more stress and pressure. […] Smoking, alcoholism, along with other vices, make the body susceptible to all types of diseases and conditions due to its effects on the immune system and the degeneration of cells.

  https://my.clevelandclinic.org/health/diseases/17499-spinal-stenosis

  Spinal stenosis has several causes. Many different changes or injuries in your spine can cause a narrowing of your spinal canal. The causes are split into two main groups: […] Acquired spinal stenosis is more common. It usually happens from wear and tear changes that naturally occur in your spine as you age. Only 9% of cases result from congenital causes. […] Causes of acquired spinal stenosis include: Bone overgrowth: Osteoarthritis is the wear and tear condition that breaks down the cartilage in your joints, including your spine. […] Acquired spinal stenosis means you develop it later in life (after birth) most commonly after the age of 50. These cases usually happen from an injury or changes in your spine that occur as you age (degenerative changes). […] Congenital spinal stenosis affects babies and children. It can happen due to: Issues with spine formation during fetal development.

• #2 Spinal Stenosis Causes | Inherited vs. Acquired

  https://www.bonati.com/conditions/spinal-stenosis/causes/

  Spinal stenosis is characterized by a narrowing of the spinal canal either in the lumbar (lower back) thoracic (mid-back) or cervical (neck) regions of the spine. This narrowing causes compression of the spinal cord or spinal nerve roots and drives the negative symptoms associated with the condition. […] Patients who suffer from spinal stenosis can be separated into those who have spinal stenosis hereditary and those who have acquired it over time. […] Patients who have inherited spinal stenosis are often born with a spinal canal that is narrower than the average person’s, and often experience the negative effects of the condition earlier in life. […] Most patients seeking spinal stenosis treatment suffer from the acquired version of the condition, as the narrowing of the spinal canal is a natural part of the aging process. Degeneration of the cartilage that provides a cushion for spinal joints exposes the bone to friction and may result in bone spurs. As this bone on bone friction continues, spinal stenosis symptoms become more pronounced and the condition worsens. Degeneration also can lead to bulging discs or herniated discs, which put pressure on the spinal nerves.

  Spinal stenosis can be caused by congenital or acquired etiologies. Only 9% of the cases result from congenital etiologies. Some common congenital causes include achondroplasia, shortened pedicles, osteopetrosis, apical vertebral wedging, spinal dysraphism, segmentation failure early vertebral arch ossification, thoracolumbar kyphosis, morquio syndrome, and osseous exostosis. […] Acquired stenosis occurs primarily from trauma, degenerative changes, iatrogenic causes, and systemic processes. Trauma usually affects the vertebral canal acutely with a mechanical force. Degenerative changes occur when there is a narrowing of the central canal and lateral recess from posterior disk herniation, ligamentum flavum hypertrophy, and spondylolisthesis.

  https://resources.healthgrades.com/right-care/spine-conditions/6-things-to-know-about-spinal-stenosis

  6. Spinal stenosis usually is caused by degenerative spine changes. Most of the time, spinal stenosis is caused by age-related changes to the spine, including wear-and-tear. Repetitive bending, twisting, and straining of the spine over a lifetime can cause a herniated disc or prompt bone spurs to grow in the vertebrae. Excess weight can intensify the problem. Other causes of spinal stenosis include trauma, such as a dislocated vertebra from a car accident and, occasionally, a spinal tumor. Some bone diseases and conditions, like Paget’s or scoliosis, can contribute to the development of stenosis, as well. Usually, though, spinal stenosis is a degenerative condition that occurs in people over age 50. […] 3. Spinal stenosis may have a genetic component. Recent research has identified potential genetic links to spinal stenosis. While stenosis itself likely cannot be inherited, researchers have found that some people’s genes may put them at higher risk of developing a narrow spinal canal or vertebral foramina. Because this research is new and ongoing, doctors cannot yet use any of this data to identify your potential risk for developing spinal stenosis or to develop new treatments that might prevent narrowing of the spinal canal before it starts.
