What are vertebral endplates?

Vertebral body endplates are anatomically-discrete structures that form the interface between the vertebral bodies and the adjacent intervertebral discs. They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer.

What is a vertebral body lesion?

Lesion is a general term for tissue that has been injured, destroyed, or otherwise has a problem. Spinal lesions affect the nervous tissue of the spine. They may be due to: Cancerous or noncancerous tumors. Trauma.

What is the current evidence on vertebral body osteonecrosis?

Evidence on vertebral body ON (VBON) is inconsistent and fragmented and mainly limited to post-traumatic cases, with a considerable overlap with nonunion and pseudoarthrosis. The actual incidence of this entity remains unknown. An idiopathic etiology for VBON has been usually reported.

What is vertebral body wedging?

The vertebral wedging angle (ɑ) is the angle between the upper endplate and lower endplate of the vertebra. The intervertebral disc wedge (β) is defined as the angular difference between the inferior endplate of the upper vertebra and superior endplate of the lower vertebra.

Can you walk with a fractured vertebrae?

Depending on how severe your injury is, you may experience pain, difficulty walking, or be unable to move your arms or legs (paralysis). Many fractures heal with conservative treatment; however severe fractures may require surgery to realign the bones.

What causes loss of vertebral body height?

Vertebral compression fractures (VCFs) occur when the bony block or vertebral body in the spine collapses, which can lead to severe pain, deformity and loss of height. These fractures more commonly occur in the thoracic spine (the middle portion of the spine), especially in the lower part.

How do you treat a spinal lesion?

The best chance for recovery of function following spinal cord injury is through prompt treatment. Early surgical decompression and stabilization leads to better recovery. Aggressive physical therapy and rehabilitation after surgery also maximizes recovery.

Are spinal lesions serious?

Treatment and Prognosis For example, lesions of the spine are referred to as central lesions because of their impact on the central nervous system. Treatment is key for spinal tumors, as any damage they cause can be made more severe (or even permanent) if treatment is not sought soon enough.

Can AVN affect the spine?

While AVN can affect any bone, it rarely occurs in your spinal bones (thoracic vertebrae). AVN of the spine is also known as vertebral osteonecrosis or Kummel disease.

What is Kummel disease?

Kummel disease is the eponym for avascular necrosis of the vertebral body after a vertebral compression fracture. As our population ages, the prevalence of osteoporosis, its most common fragility fracture (vertebral compression fracture), and Kummel disease will increase.

What causes vertebral wedging?

When an external force is applied to the spine, such as from a fall or carrying of a sudden heavy weight, the forces may exceed the ability of the bone within the vertebral body to support the load. This may cause the front part of the vertebral body to crush forming a wedge shape.

Can wedged vertebrae be fixed?

Surgery is indicated when the loss exceeds 50%. Spinal instrumentation and/or fusion can be utilized to restore lost height. Surgically treating wedge fractures includes restoration of vertebral height and providing spinal column stability using instrumentation and fusion.

How are vertebral endplate changes redefined with MRI?

Vertebral endplate changes were redefined with the advent of MRI, which enabled visualization of previously unrecognized alterations in marrow signal. Modic et al. proposed a formal classification of these changes in 1988. 1 Two types of endplate changes were originally described, with a third type subsequently added in a later publication: 2, 3

What are the two types of vertebral endplate changes?

Type 1: Decreased signal intensity on T1-weighted images and increased signal intensity on T2-weighted images. Type 2: Increased signal intensity on T1-weighted images and isointense to marrow or mildly increased signal intensity on T2-weighted images.

Which is part of the bone is involved in metaphysis?

Metaphyses are radiographically irregular with cystic changes across the entire width of the bone. Composed of stalk, marrow, and cortex; all continuous with normal underlying bone Lesion may be sessile (broad-based), mimicking undertubulation of metaphysis

What are the anomalies of vertebral body shape?

One neonatal presentation as a result of intrauterine osteoporosis is collapse of many vertebral bodies. Osteoporosis. Multiple fractures and healing or healed fractures elsewhere in the skeleton. Pear shaped vertebral bodies with significant decrease in height, kyphoscoliosis, and irregular epiphyses. Short trunk.
