The Delicate Nature Of Spinal Cord Injuries

Spinal CordEach year in the United States, over 10,000 people suffer a spinal cord injury, also called SCI: any damage to the spinal cord that results in loss of function or mobility. Such injuries can be caused by trauma or disease and can result in temporary or permanent loss of sensation, loss of movement (paralysis), or loss of bowel or bladder control.

Pathways for the Central Nervous System

The spinal cord itself is one of the bodies' most important systems, vital to the transfer of neural signals between the brain and the rest of the body. What many people forget is that the spinal system itself consists not just of lumbar vertebrae, but also major components of the central nervous system. It is divided into 31 different parts, segmented into three main sections - "upper back", "mid back" and "lower back". This is important to note because each one of these 31 parts controls various sensations in the body through spinal nerves. In addition to the nerves, there are major arteries running through the back as well, including the left and right posterior arteries.

But, let's focus on the nerves that run through the spine for a moment, because in most cases where an injury is involved to the spine, that is where they occur. The upper section of nerves in the spine, called cervical spinal nerves, exit through the various openings in the bones or vertebrae. Each vertebra has a numbered location, with those in the cervical area being labeled C-1 through C-7. The middle section, or thoracic spine, are labeled T-1 through T-12. In the lower back, the lumbar vertebrae are represented by L-1 through L-5. Each nerve exiting these areas control different pathways in the body, and in turn, injuring any one of them could cause sensations to occur in different areas.

Long Term Effects of Trauma

For example, the L-4 and L-5 lumbar spinal nerves control the pathways that end up reaching the toes and the foot. So, if you are involved in say a car accident where this part of your back has been injured, that could lead to further pain running down into your feet and toes. Even though the toes themselves were not subject to trauma, it is the damaged nerves leading from the spine which will cause them to feel this way. The nature of the injury depends entirely on whether the spinal cord and nerve root itself were damaged and the subsequent inflammation that occurs.

Typically, in today's age spinal cord injures are usually suffered in motor vehicle accidents, sports injuries, and slip & falls. Damaged nerves can lead to a loss of sensation, weakened muscles, a "buzzing" electrified feeling in affected areas, or even paralysis.

There are two types of injury - complete and incomplete. A complete injury is one in which the victim has no sensation or voluntary motor movement on either side of the body below the level of the injury. If the victim has some feeling or partial movement, it is called an incomplete injury.

Afferent and Efferent Nerves

The nerves that branch out from the spine form a closed loop from the spinal column to the muscles and skin with the following steps - #1 "Sensation", the body feels a feeling and the message is relayed to the spinal cord - #2 "Decision", the message is sent from the spinal cord to the brain and then - #3 "Reaction", where the brain relays the message back through the spinal column to the nerve. Damage caused to either end of these loops can lead to entirely different issues and losses of sensation.

When a sensation is felt in the body, that feeling is picked up by a nerve located near the skin. In order for this feeling to be "felt" though, it must first travel to the spinal column via what is called an afferent nerve. The spinal column then transmits any messages that the nerve may have been sending back up to the brain - such as "ouch, that hurts". Any messages sent back to the nerve by the muscles near the skin are then sent through what are called efferent nerves, which allow the person to then respond to the sensation. All of this happens nearly instantly, seamlessly to us as the feelings are felt and then reacted upon. But, when those messages the brain is sending and receiving from other parts of the body are relayed through damaged neurons, the messages themselves can become muddled or diluted. This is what leads to the differing sensations resulting to injuries to these nerves, whether it is from a car accident or any other type of trauma.

How Insurance Handles Spinal Injuries

Frequently, insurance companies will delay spinal cord treatment to seek a cheaper option. Time is of the essence, especially when a nerve itself has been damaged, and the quicker it is acted upon, the higher the chances are for a successful recovery. That's why it's very important that, if you have suffered a spinal cord injury, you contact a qualified attorney who can make sure you are getting the proper treatment needed.

A spinal cord injury usually involves swelling of the spinal cord which affects the whole body. When the swelling goes down, the patient may regain function months or years after the injury but it is rare for all functioning to be recovered. Treatment presently consists of stabilizing any broken vertebrae, maintaining the patient, preventing movement to the injured area, and reducing swelling.
