How Do You Get Schmorl’s Nodes? Most can form after a heavy loading incident or trauma which forces the nucleus part of the disc through the endplate instead of the outer part of the disc. The outer part of the disc is normally more resistant to sudden forces than the endplate, especially in young individuals.
What causes Schmorl’s node?
The exact cause of Schmorl’s node is not completely understood. However, it is thought that some Schmorl’s nodes may occur when vertical forces (e.g., walking, standing straight, landing from a high jump, etc.) are transmitted through a weakened vertebral endplate, causing the protrusion of the intervertebral disc.
What is a Schmorl’s node herniation?
In most spinal disc herniations, the herniated disc slips laterally to either side of the spine, causing an intervertebral disc herniation. With Schmorl’s node, however, the herniated disc slips downwards or upwards into the adjacent vertebrae through a defect of the vertebral endplate, causing an intravertebral disc herniation .
What are Schmorl's nodes and how can they be treated?
Schmorl's nodes, also known as Schmorl's nodes syndrome, is a deformity of the vertebrae. The condition can occur through sudden or repeated trauma to the back or as vertebrae degenerate over time. Certain exercises may help ease the condition. These exercises should be undertaken only under the supervision of your doctor or physical therapist.
What are Schmorl's nodes and a discs?
A disc sits between each bone of the vertebrae as a shock absorber to cushion jolting movements. Schmorl's nodes occur when discs break through the vertebral wall, enabling the soft tissue within the discs to penetrate between the vertebrae. Schmorl's nodes are generally found in the middle and lower spine.
Are Schmorl's nodes caused by trauma?
Conclusion: Schmorl's nodes do occur acutely as the result of a single traumatic episode, and are almost always associated with other acute spinal injury. The frequency and occurrence of acute Schmorl's nodes in motorcyclists suggest that axial loading is an important mechanism.

What is a Schmorl's nodule?
Introduction. First described in 1927, a Schmorl's node (SN) is the herniation of nucleus pulposus (NP) through the cartilaginous and bony end plate into the body of the adjacent vertebra. SNs are common findings on imaging, and although most SNs are asymptomatic, some have been shown to become painful lesions.
What is an acute Schmorl's node?
Schmorl nodes, also known as intravertebral disc herniations, refer to protrusions of the cartilage of the intervertebral disc through the vertebral body endplate and into the adjacent vertebra. The protrusions may contact the marrow of the vertebra, leading to inflammation.
Does endplate cause pain?
Vertebral endplates are much more nerve-dense than spinal discs, which means they're more susceptible to pain than discs. Vertebral endplate nerve dysfunction is when the endplate and the nerves within it become compressed, causing a great deal of pain.

Where do Schmorl's nodes occur?
Although Schmorl’s nodes can develop anywhere on the spinal column, they primarily occur on the upper lumbar spine. The nodes typically affect the lower, or inferior, endplate of thoracic vertebrae and the upper, or superior, endplate of lumbar vertebrae.
What is the difference between acute and chronic Schmorl's nodes?
On the other hand, acute Schmorl’s nodes have a sudden onset and are often related to a recent trauma or injury. Acute Schmorl’s nodes can be distinguished from chronic Scmorl’s nodes on an MRI by the presence of inflammation of the surrounding vertebral bone.
Can Schmorl's nodes cause pain?
More rarely, Schmorl’s nodes can become infected or cause irritation of the nerves that run down the spine, which may lead to pain radiating down the leg, numbness, or muscle weakness.
Is Schmorl's node common?
Schmorl’s nodes are fairly common in the general population, affecting both young and older individuals. Their clinical significance is still not clear, but several studies suggest they could be indicative of the natural degeneration of the spine that occurs over time.
How do Schmorl's nodes form?
Another mechanism through which a Schmorl’s nodes is characterized by is extrusions of the spinal disc. In a Schmorl’s Node, the spinal disc, extrude into the vertebral body either cranially (towards the head or top), or caudally (towards the feet or bottom) or both, in rare instances. These extrusions into the body of a vertebra are through a narrow aperture in the end-plate. Other mechanisms through which Schmorl’s nodes form is unclear, but possibly as the result of trauma, tumors and congenital weaknesses of the cartilage, arising from the failure to heal spaces occupied by blood vessels during development.
Does Schmorl's node occur in later life?
However, they are thought to predispose the disc to degeneration in later life. Schmorl himself attributed these lesions to foci degeneration in the cartilaginous end-plate.
What is a Schmorl's node?
By definition, a Schmorl’s Node (also known as Schmorl’s nodules) is either a downward or upward notching or protrusions (pushing) of the spinal disc cartilaginous structures, and bony surfaces of spinal bones called vertebrae. Schmorl’s Node is a common occurrence of degenerative changes with aging, detected in routine spine x-rays.

Therefore, you should take steps to avoid the complications of additional spinal disorders as you age if you have Schmorl’s Nodules.
Are Spinal Nodes Painful?
A Schmorl’s node is not painful, but they interfere with transferring nutrients from the spinal vertebrae to the spinal disc. The spinal disc does not have a direct blood supply and, as such, is considered avascular. However, they still require a constant flow of blood, which brings in the needed nutrients. The nutrient-rich blood to the spinal disc is obtained through the process of diffusion or soaking up. So, the spinal discs are dependent on the blood vessels within the vertebrae to give them nutrition. Without the needed nutrient, your spinal disc becomes weak, wearing, slipping, and tearing prematurely. So, while a Schmorl’s Node does not cause pain by itself, it can lead to other conditions.

However, there is literature that indicates in about a year and a half, about 26% will increase in size and about 13% will show modic type 1 changes surrounding the node. It is also indicated that these active nodes may increase the risk of vertebral fractures by about 10%.
What is the treatment for acute node fracture?from necksolutions.com
An acute node that is symptomatic can be treated similar to compression vertebral fractures. Initial conservative measures often consist of pain and/or anti-inflammatory medications, bed rest and external lumbar and/or thoraco-lumbar bracing. Heat and ice can be used accordingly and after the initial inflammation has subsided, some find spinal traction devices beneficial.
Why does my node hurt?from necksolutions.com
If a node is not painful, it can produce symptoms if the nucleus keeps herniating more into the bone marrow. Once there is contact of the nucleus with the blood, an inflammatory immune reaction can result in pain and further structural damage to the bone itself as well as the disc.
Where is Schmorl's disease most commonly found?from radiologykey.com
They reportedly occur more frequently in males and more commonly near the thoracolumbar junction. The “classic” Schmorl’s occurs in the middle one third of the vertebral endplate and is most commonly located slightly posterior to the central axis of the vertebral endplate ( Fig. 64-6 ) .
Pathophysiology
Significance
- A Schmorls node is typically found in the thoracic or lumbar spine (mid or lower back) and is most often not a major finding, as they are fairly common. However, after a decade, we are still trying to learn the significance of these Schmorls nodes. These nodes are usually noted as a long-term finding without any symptoms and are found in about 30% of the population.
Causes
- The location of most nodes indicate axial loading (vertical forces) are a major cause. When there is an injury that affects the spine in these up and down directions, nodes can occur. They will sometimes show edema (swelling) or a light area around the node. The edema may resolve in as little as 6 months, or may persist for some years. In some cases they are factors which can mak…
Symptoms
- There are studies which indicate that Schmorls nodes that produce symptoms can be very painful, with high pain levels reported by patients as well as significant effects on quality of life.
Clinical significance
- Damage to the endplate can result in a loss of pressure to the inner part of the disc and placing more stress on the outer part, therefore, damage to the endplate can cause a series of mechanical and biochemical events that lead to degeneration and chronic back pain. It appears that higher levels of spinal loading; higher BMI (e.g., weight gain during pregnancy), lifting heavy objects, an…
Effects
- Even without infection, the inner part of the disc, when in contact with the blood supply of the inside of the bone can cause a significant immune response resulting in high levels of swelling, pain producing chemicals called cytokines, and high levels of pain which can follow a pattern of inflammation related pain of worse in the morning, better at noon, getting bad again in the aftern…
Prognosis
- When doing follow-up imaging studies, most nodes are stable. However, there is literature that indicates in about a year and a half, about 26% will increase in size and about 13% will show modic type 1 changes surrounding the node. It is also indicated that these active nodes may increase the risk of vertebral fractures by about 10%. Like modic changes, the invasion into the b…
Epidemiology
- A 2016 study in Osteoarthritis & Cartilage found an association between lumbar spine Schmorls Nodes and Disc Degeneration in a large scale population based study using MRI. The authors found there are typical and atypical nodes with distinct characteristics. The atypical nodes appear either rectangular or irregular in shape, while typical are round. They found typical nodes were a…
Prevention
- The authors recommend health care professionals be aware of the connection between these nodes and stenosis. They recommend lumbar stabilization exercises may be useful in preventing or delaying stenosis as a consequence of Schmorls nodes.
Research
- A 2018 study in the journal Biomed Research International found nodes associated with lower disc height, degenerative spinal stenosis, osteophytes, vacuum phenomenon (radiographic description of gas in the vertebral body), smoking and higher bone height. A 2019 study in the journal Neuroradiology used guided percutaneous vertebroplasty in the management of painful …
Treatment
- An acute node that is symptomatic can be treated similar to compression vertebral fractures. Initial conservative measures often consist of pain and/or anti-inflammatory medications, bed rest and external lumbar and/or thoraco-lumbar bracing. Heat and ice can be used accordingly and after the initial inflammation has subsided, some find spinal traction devices beneficial. Chiropr…
Medical uses
- A 2017 study and follow up in Pain Physician Percutaneous Vertebroplasty, often used to treat painful compression fractures, is a safe and effective procedure for Schmorls nodes that are symptomatic. The authors note it can be used for those who have not responded to conservative therapies or nerve/disc blocks. It is a procedure done under local anesthesia, where a type of ce…
Diagnosis
- A 2017 retrospective study in Medical Science Monitor found those with nodes that are symptomatic may have pain similar to an acute compression fracture. MRI is indicated when CT and x-rays are unremarkable. MRI can show inflammation around painful nodes.
Benefits
- In the study, the authors found significant improvements for PKP, stabilizing vertebral integrity and maintaining functional improvements at 5 year follow up. They concluded PKP to be both safe and effective in those not responding to conservative therapy.
