Understanding Spinal Cord Injuries
Spinal cord injuries can be very devastating. First we will discuss the spinal cord's structure and function. Then we will tell you how the spinal cord is most commonly injured, along with some statistics involved and some signs of spinal cord injury. We will explain some changes to the body after spinal injuries. Finally we will talk about some of the research in helping spinal cord injury victims. The spinal cord is the final common pathway from the brain to the muscles. It controls all the sensory inputs received from different locations throughout the body. The spinal cord also controls voluntary muscle responses. Some elementary reflexes are local to the spinal cord, but voluntary muscle

Nerves from each segment of the spinal cord connect to specific regions of the body. The cervical region or neck are referred to as C1 through C8; they control signals to the neck, arms, and hands. The segments in thoracic or upper back region T1 through T12 relay signals to the torso and some parts of the arms. The segments in the upper lumbar or mid-back region just below the ribs, L1 through L5, control signals to the hips and legs. Last, the sacral segments S1 through S5 lie just below the lumbar segments in the mid-back and control signals to the groin, toes, and some parts of the legs. The effects of spinal cord injury at different segments reflect this organization.(SC-Basic Anatomy of Spine-http://www.goes.com/billr/html/_anatomy_of_a_spinal_cord.html) Injuries to the spinal cord may be caused indirectly, as by a blow to the head or a fall; by traffic accidents, sports injuries, or violence. The consequences depend on the amount of damage the cord sustains and where the damage occurs. Although spinal injuries are only a small fraction of all injuries; accidents cause an estimated 10,000 spinal cord injuries each year. Each year, more than two million Americans suffer a
* Following a SCI, the first priority is often to help the patient develop as much possible strength in the
Movement of the deltoid begins in the cerebrum of the brain, but more specifically: in the frontal lobe, the premotor cortex is relaying instructions to the primary motor cortex. The primary motor cortex contains the upper motor neurons whose axons will travel down the pyramids of the medulla oblongata and synapse on lower motor neurons in the anterior gray horns of spinal cord segments C5-C6. From there, the ventral rami of spinal nerves C5-C6 form the superior trunk of the brachial plexus, which splits into two divisions. We will follow the posterior division that supplies to extensor muscles. This posterior division then runs into the posterior cord from which the axillary nerve is derived. The axillary nerve’s motor end innervates the deltoid through its neuromuscular junction.
The cervical spinal nerve C3-5 innervate the phrenic nerve. These are the lower motor neurons.
The spine is one of the most important structures in the human body. The spine is located in the dorsal cavity and consists of 24 bones, called vertebrae. These vertebrae play a crucial role in protected the body’s command center, the spinal cord. But what happens when a disorder prevents the spinal column from functioning correctly? Scoliosis is a musculoskeletal disorder that causes abnormal lateral curvature of the spine and it effects millions of people in the US per year. I have chosen this disorder because I am aspiring to become a chiropractor and scoliosis is a typical condition that chiropractors help treat on a daily basis.
Now that I have shared a brief overview of the spinal cord and some statistics about spinal cord injuries, we will look at the past research that has led to the treatments most commonly used today. In 1990, a steroid called dexamethasone was discovered in human trials to preserve some motor and sensory function if administered at high doses within 8 hours of injury. Surgery used to remove fluid, tissue, or bone fragments, or to stabilize fractured vertebrae by fusing bones or inserting hardware has also proven to be one of the most thorough measures to prevent further harm. I received both of these treatments after my accident, and they are the same that have been used for the past decade. Until recently, doctors had no way of limiting such disabilities, aside from stabilizing the cord to prevent added destruction, treating infections, and prescribing rehabilitative therapy to maximize any remaining capabilities.
A Spinal Cord Injury is damage to any part of the Spinal Cord nerves at the end of the Spinal Canal. Every Year, 17,000 Spinal Cord Injuries are reported in the USA alone. The Most Frequent age for Spinal Cord Injuries is 19. Almost 200 Spinal Cord Injuries were reported for High School Football. People who suffer from SCI (Spinal Cord injuries) can experience muscle weakness, poor coordination, and overactive reflexes.There is many
Continuing on we as a class learned about the spinal cord, which is a column of nerves lining our back, as well as the central nervous system, which is the human body’s main processing unit. Chapter two focuses primarily on these two aspects of the body. The central nervous system is the brain and spinal cord, the brain, hindbrain, and midbrain are in charge of the senses. Hearing and sight for example are dealt with in the forebrain. The nervous system includes many different working pieces that control the body. Such as Dendrites; these are the hairs on the neurons. Ions have both negative and positive neurons which each has three, included with the soma in the cell body. Axon is the long tube of it, and the terminal button is the end of the tube.
This essay is not intended to criticize any emergency medical or hospital staff. I am writing this essay out of concern for patients who come into the emergency room that may have a jeopardized spinal cord resulting from an injury or suspected injury to their cervical spine. I am a certified emergency medical technician, farm-medic instructor and currently a medical diagnostic student doing clinicial's. In the United States each year there are approximately 10,000 reported cervical spine injuries that come into emergency rooms. Motor vehicle accidents account for approximately 45%, falls approximately 30%, the remaining 25% from sports and miscellaneous. Although only a small amount of
Spine injuries hurt a lot for example your spine can pop outback this up. 2-100,000 get spine injuries.
The central nervous system is what connects the brain to the muscles of the body. When a patient has an injury to the spinal cord, movements in certain parts of the body will be affected based on the location of the injury. If the injury affects hand motion then many day to day tasks are affected. This literature review seeks to understand how an injury to the spinal cord impacts movement, and what has been done so far to help those affected by spinal cord injuries.

Spinal injuries can happen to anyone. There are less than 200,000 cases in the US each year, and most of the time this injury can not be completely cured. The spinal cord is about 18 inches long, it is a bundle of nerves which contains neurons that carry signals between the brain and body. The spinal cord has sections, C1-C8, T1-T12, L1-L5, the sacrum, and the coccyx. The C stands for Cervical, the T for Thoracic, and the L stands for Lumbar. Injuring different sections signifies different problems and diagnosis. The spinal cord controls the body. It controls sensory messages which include sense of touch, pain, pressure, temperature, and body position. It controls motor messages which tell the body what to do. For example, legs, arms, hands,
The limited space within the vertebrae actually plays an important roll in spinal cord injury. Once the initial injury occurs the body, as with every other part of the body, tries to protect the injured area with swelling. But the swelling occurs within the small confines of the spinal column and causes further damage to the surrounding tissue. It has only recently been discovered how much of an impact this secondary damage has. One of the areas of crucial ongoing research is on what kind of window of opportunity medicine has in treating these types of injuries and still attaining the best recovery.
Spinal cord injuries are characterized by two distinct injury phases. The primary injury phase is represented by all the tissue directly damaged at the time of injury. The damage seen in this phase is primarily shearing of cells, destruction of local vasculature, and severe disruption of spinal cord function. The secondary injury phase is characterized by inflammation of the injury site, immune-mediated tissue destruction, and edema formation at the lesion site. The nature of spinal cord injuries makes the damage done by the primary injury irreversible. The majority of therapeutic research is done with the intention of lessening the damage done during the secondary injury phase. One major complication faced by researchers trying to control the secondary injury phase is the localized destruction of vasculature. Without a constant supply of oxygen and nutrients, many of the cells in the spinal cord will begin to die rapidly, oftentimes releasing biological signals that encourage other cells to die as well. The uncontrolled movement of fluid into the lesion site causes the tissue to swell, further complicating the processes of rebuilding vasculature. The movement of immune
A review of the literature regarding spinal immobilisation has been undertaken using databases for PubMed, MEDLINE, CINAHL, OVID and Cochrane EBM. Reviews were electronically searched using the subject headings “spinal injuries”, “spinal immobilisation” and “management of spinal injuries”. The results generated by the search were limited to English language articles and reviewed for relevance to the topic. The aim of this literature review is to compare and contrast the views on spinal immobilisation and to achieve a better knowledge of evidence based practice.
