What are the locations that spinal cord injuries can occur?

What are the locations that spinal cord injuries can occur?

Damage to nerve fibers A chest (thoracic) or lower back (lumbar) injury can affect your torso, legs, bowel and bladder control, and sexual function. A neck (cervical) injury affects the same areas in addition to affecting movements of your arms and, possibly, your ability to breathe.

Which region of the spinal cord if injured can cause paralysis of the arms and legs?

Thus, the body at and below the level of injury is affected. For example, in an injury to the spinal nerves in the neck area (C1 through C8), messages are stopped in the neck area. This usually results in at least some paralysis of the chest, arms, and legs (tetraplegia, also known as quadriplegia).

Which reflex is absent in spinal cord injury?

Reflexes above the level of the spinal cord injury remain unaffected while those below the level of injury are either depressed (hyporeflexia) or absent (areflexia).

What is the most common location of all spinal injuries?

The most common sites of injury are the cervical and thoracic areas. SCI is a common cause of lifelong (permanent) disability and death in children and adults. The spine has 33 vertebrae.

Is neurogenic shock temporary?

Neurogenic shock results from damage to the spinal cord above the level of the 6th thoracic vertebra. It is found in about half of people who suffer spinal cord injury within the first 24 hours, and usually persists for one to three weeks. Neurogenic shock may be caused by severe brain injury.

Why does the location of an injury to the spinal cord affect what the results are of the injury?

The most common is loss of motor, sensory and slowing of some of the body’s internal organs (autonomic nerve function) below the level of the injury. In general, the higher in the spinal cord an injury occurs, the more function, sensation and internal body functions will be affected.

What is the difference between spinal and neurogenic shock?

Spinal shock occurs in phases (I–IV) that are temporally distributed over a period of weeks to months, whereas neurogenic shock tends to have sudden onset that requires more urgent management.

What are the symptoms of a C4 spinal cord injury?

Symptoms of a spinal cord injury corresponding to C4 vertebrae include: Damage to the spinal cord at the C5 vertebra affects the vocal cords, biceps, and deltoid muscles in the upper arms. Unlike some of the higher cervical injuries, a patient with a C5 spinal cord injury will likely be able to breathe and speak on their own.

How does spinal cord injury affect upper arm?

A C5 spinal cord injury directly affects sensation around the outer area of the upper arm. Additionally, the C5 spinal nerves connect to the deltoids (which are responsible for shoulder movement), biceps, and brachioradialis (which are responsible for elbow flexion and upward rotation of the forearm).

How does spinal cord injury affect your fingers?

C8 – The C8 nerve roots affect sensation at the ring and pinky fingers. The myotomes at the C8 level affect the ability to bend your fingers and grab objects. After the cervical region is the thoracic region.

How does spinal cord injury affect elbow flexion?

The C6 myotomes affect elbow flexion and wrist extension. C7 – The C7 nerve roots affect sensation at the middle finger. It affects the ability to straighten out your elbows and bend your wrists. C8 – The C8 nerve roots affect sensation at the ring and pinky fingers.

What happens when spinal cord injury level is below C5?

As it sounds, an incomplete injury at C5, for example, may result in partial motor or sensory below the level of C5. If the injury was complete, motor or sensory below C5 would be absent. What is the ASIA scale? The ASIA scale stands for the American Spinal Injury Association scale and is used to describe the level of a person’s spinal cord injury.

Where does cervical spinal cord injury usually occur?

Injuries to C1 and C2 are very rare and most injuries to the cervical spinal column occur near the C4 / C5 levels. While no two spinal cord injuries are the same, early treatment is critical to the long-term prognosis of any injury to the cervical spinal column.
