The pathophysiology of spinal cord injury can be categorized as acute impact or compression. Acute impact injury is a concussion of the spinal cord. This type of injury initiates a cascade of events focused in the gray matter, and results in hemorrhagic necrosis.
What is spinal cord pathology?
Spinal cord injury (SCI) is a severe, often life threatening, traumatic condition leading to serious neurological dysfunctions. The pathological hallmarks of SCI include inflammation, reactive gliosis, axonal demyelination, neuronal death, and cyst formation.
What is the pathophysiology of paraplegia?
Paraplegia often involves loss of sensation (of pain, temperature, vibration, and position) as well as loss of motion. It may also include paralysis of the bladder and bowel. Paraplegia may be caused by injury to or disease of the lower spinal cord or peripheral nerves or by such brain disorders as cerebral palsy.
What is spinal cord damage?
A spinal cord injury (SCI) is damage to the tight bundle of cells and nerves that sends and receives signals from the brain to and from the rest of the body. SCI can be caused by direct injury to the spinal cord itself or from damage to the tissue and bones (vertebrae) that surround the spinal cord.
What is the most common cause of paraplegia?
Paraplegia happens when there is damage below the neck. The most common cause is trauma, such as from a sports injury or car accident. Other causes are: Stroke.
What are the complications of paraplegia?
Complications resulting from paraplegia may include:
- Pressure sores (decubitus)
- Bladder and bowel incontinence.
- Circulation disorders.
- Autonomic dysreflexia.
- Loss of muscle tone.
What is the difference between paraplegia and paraparesis?
Paraparesis occurs when you’re partially unable to move your legs. The condition can also refer to weakness in your hips and legs. Paraparesis is different from paraplegia, which refers to a complete inability to move your legs.
What is the difference between spinal injury and spinal cord injury?
SCI is very different from back injuries such as ruptured disks, spinal stenosis or pinched nerves. A person can “break their back or neck” yet not sustain a spinal cord injury if only the bones around the spinal cord (the vertebrae) are damaged, but the spinal cord is not affected.
What are the symptoms of spinal cord problem?
Symptoms of a Spinal Cord Disorder
- Weakness or paralysis of limbs.
- Loss of sensation.
- Changes in reflexes.
- Loss of urinary or bowel control.
- Uncontrolled muscle spasms.
- Back pain.
What are the two types of spinal cord injuries?
Spinal cord injuries can be divided into two types of 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.
