What is the most common cause of a spinal cord injury?
The leading causes of spinal cord injury are road traffic crashes, falls and violence (including attempted suicide). A significant proportion of traumatic spinal cord injury is due to work or sports-related injuries.
What are two types of spinal cord injuries *?
Most cases can be divided into two types of spinal cord injury – complete spinal cord injury vs. incomplete: A complete spinal cord injury causes permanent damage to the area of the spinal cord that is affected. Paraplegia or tetraplegia are results of complete spinal cord injuries.
Who is at risk for spinal cord injury?
Young adults – more than half of spinal cord injuries happen to people age 16-30. Elderly people – usually from falls. People active in sports – high-risk athletics, in particular. People with bone or joint conditions – for example arthritis, osteoporosis.
What are the 4 sections of the spine?
What are the spine segments?
- Cervical (neck): The top part of the spine has seven vertebrae (C1 to C7).
- Thoracic (middle back): The chest or thoracic part of the spine has 12 vertebrae (T1 to T12).
- Lumbar (lower back): Five vertebrae (L1 to L5) make up the lower part of the spine.

What is the most common level of spinal cord injury SCI?
The percentage of spinal cord injuries as classified by the American Spinal Injury Association (ASIA) is as follows: Incomplete tetraplegia: 29.5% Complete paraplegia: 27.9% Incomplete paraplegia: 21.3%
What is the most common causes of spinal cord injuries?
What are 5 parts of the spine?
Sections. The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What are lesions of the spinal cord?
Lesions of the spinal cord Spinal cord lamination Complete spinal cord transection (Transverse myelopathy) All acsending tracts from below the level of the lesion and all descending tract from above the level of lesion interrupted.
What is the pathophysiology of bilateral spinal cord lesions at C5?
As an example, a bilateral spinal cord lesion at C5 disrupts the corticospinal tracts at that level, and creates UMN signs in both lower limbs, as well as in the distal upper limbs, since those affected muscles are not innervated by the C5 anterior horn cells or ventral motor roots.
How do you know if you have a lesion on your spine?
You may not be able to pinpoint where your pain is coming from. But if the lesion affects the spinal nerve roots or spinal cord, you are likely to have nerve symptoms, which can include weakness, numbness, tingling, or electrical shock-like feelings going down one leg or arm.
Do MRI features of spinal cord infarction and aqp4-ab positive NMOSD overlap?
The MRI features of spinal cord infarction and AQP4-Ab positive NMOSD can overlap,18with no significant differences in lesion length, cross-sectional area and cord expansion. However, 62% of AQP4-Ab positive NMOSD cases have lesions located within 7 cm of the foramen magnum, compared with no cases of spinal cord infarction.
