Acute Spinal Cord Injury (SCI)
What is an acute spinal cord injury?
Your spine is made of many bones called vertebrae. Your spinal cord runs downward through a canal in the center of these bones. The spinal cord is a bundle of nerves that carries messages between the brain and the rest of the body for movement and sensation.
Acute spinal cord injury (SCI) is a traumatic injury that bruises, partially or completely tears the spinal cord. SCI is a common cause of permanent disability and death in children and adults.
What causes an acute SCI?
Many things can cause SCI. The more common injuries occur when the area of the spine or neck is bent or compressed, as in the following:
Motor vehicle accidents, such as automobiles, motorcycles, and being struck as a pedestrian
Violence, such as gunshot or stab wounds
Infections that form a collection of pus (abscess) on the spinal cord
Birth injuries. These typically affect the spinal cord in the neck area.
Who is at risk for acute SCI?
Some people are at higher risk for SCI than others. The average age at the time of injury has increased over the past few decades and is currently 42 years. Most people who suffer SCIs are male. Non-Hispanic whites are at higher risk for SCI than any other ethnic group.
What are the symptoms of an acute SCI?
Symptoms of an acute SCI can vary widely. The location of the injury on the spinal cord determines what part of the body is affected and how severe the symptoms are.
Right after a spinal cord injury, your spine may be in shock. This causes loss or decrease in feeling, muscle movement, and reflexes. As swelling eases, it will be easier for your healthcare provider to find out the extent of injuries.
Generally, the higher up the level of the injury is to the spinal cord, the more severe the symptoms. For example, an injury to the neck, the first and second vertebrae in the spinal column (C1, C2), or the mid-cervical vertebrae (C3, C4, and C5) affects the respiratory muscles and the ability to breathe. A lower injury, in the lumbar vertebrae, may affect nerve and muscle control to the bladder, bowel, and legs, and sexual function.
The extent of the damage to the spinal cord determines whether the injury is complete or incomplete.
A complete injury means that there is no movement or feeling below the level of the injury.
An incomplete injury means that there is still some degree of feeling or movement below the level of the injury.
These are the most common symptoms of acute spinal cord injuries:
Loss of voluntary muscle movement in the chest, arms, or legs
Loss of feeling in the chest, arms, or legs
Loss of bowel and bladder function
The symptoms of SCI may look like other health conditions or problems.
How are acute SCIs diagnosed?
Acute SCI is a medical emergency. Emergency evaluation is needed anytime there is a suspected injury to the spinal cord.
The effects of an SCI may not be clear at first. A full health evaluation and tests are needed. During the exam, the healthcare provider will ask about your health history and how the injury occurred. A spinal cord injury can cause ongoing nerve problems that require more medical follow-up. Sometimes, surgery is needed to stabilize the spinal cord after acute SCI.
Diagnostic tests may include:
X-ray. This test uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
CT scan. An imaging test that uses X-rays and computer technology to make detailed images of the body. A CT scan shows images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
MRI. This test uses large magnets, radiofrequencies, and a computer to make detailed images of organs and structures within the body.
How is an acute SCI treated?
SCI requires emergency medical attention on the scene of the accident or injury. After an injury, your head and neck will be immobilized to prevent movement. This may be very hard when you are frightened after a serious accident.
There is currently no way to repair a damaged or bruised spinal cord. But, researchers are actively seeking ways to stimulate spinal cord regeneration. The severity of the SCI and the location determines if the SCI is mild, severe, or fatal.
Surgery is sometimes needed to assess the injured spinal cord, stabilize fractured backbones, release the pressure from the injured area, and to manage any other injuries that may have been a result of the accident. Your treatment may include:
Observation and management in the intensive care unit (ICU)
Medicines, such as corticosteroids to help decrease the swelling in the spinal cord
Breathing machine (mechanical ventilator), to help you breathe
Bladder catheter, a tube that is placed into the bladder. This helps to drain urine into a collection bag.
Feeding tube. This is put through the nostril to the stomach. Or it is put directly through the abdomen into the stomach. The tube provides extra nutrition and calories.
Recovery from a SCI often requires long-term stay in a hospital and rehabilitation. You will be cared for by a team of healthcare providers from many fields. The team will include nurses, therapists (physical, occupational, or speech), and other specialists. They will work to control your pain and to monitor your heart function, blood pressure, body temperature, nutritional status, bladder and bowel function, and attempt to control involuntary muscle shaking (spasticity).
Can acute SCIs be prevented?
There is no sure way to prevent SCI, but there are many steps you can take that might lower your risk. These include:
Don’t drive when you are under the influence of alcohol or drugs.
Always wear a seat belt while in a vehicle.
Take precautions to prevent falls around your home.
Keep firearms unloaded and locked away.
Wear a helmet when riding a motorcycle or taking part in any sports or activities that may result in head injury. These include bike riding, skiing, hockey, and football.
Living with an acute SCIs
Physical therapy will likely be a very important part of your rehabilitation. In this treatment, specialists will work with you to prevent muscle wasting and shortening (contractures), and to help you retrain other muscles to aid in mobility and movement. Another type of therapy is occupational therapy. It helps you learn new ways of doing everyday tasks in spite of your new physical limitations.
A traumatic event that results in a SCI is devastating to both you and your family. The healthcare team will help educate your family after your hospital stay and rehabilitation on how to help care for you at home. They will also help you understand the specific problems that need medical attention right away.
You will need frequent medical evaluations and testing after your hospital stay and rehabilitation to monitor your progress.
It’s important to focus on maximizing your capabilities at home and in the community.
You may feel sad or depressed after your injury. If this happens to you or a loved one, your healthcare provider may recommend that you see a mental health professional. Antidepressants and talk therapy (psychotherapy)can help treat depression.
When should I call my healthcare provider?
Depending on the severity of the injury, some people might recover some of their lost function, but others might continue to have long-term problems. Be sure to talk with your healthcare provider about when you would need to call them.
Your healthcare provider will likely advise you to call them if any problems you are having become worse, including weakness, numbness or other changes in sensation, or changes in bladder or bowel control.
People who have serious long-term effects from a spinal cord injury can also develop a number of other complications. Your healthcare provider might advise you to call them if you have problems such as:
Skin sores or infections
Fever, cough, or other signs of infection
Not urinating regularly or having severe diarrhea or constipation
Severe muscle cramps or spasms
An acute spinal cord injury is caused by trauma to the spinal cord. It is a medical emergency that needs to be treated right away.
The severity of symptoms (such as weakness, paralysis, and loss of feeling) depends on how badly the spinal cord is damaged and where on the cord the injury occurs. Damage to the cord in the middle of the back might affect only the legs, whereas damage to the spinal cord in the neck might also affect the arms and even the breathing muscles.
Treatment might include surgery, medicine , and other treatments as needed. Some people might recover some function over time, but others might continue to have long-term problems. Physical and occupational therapy can help you adapt to new ways of doing things.
