Spinal Cord Injury

Spinal Cord Injury

What is spinal cord injury?

The spinal cord is an elongated and cylinder-shaped collection of nerves that arise from the end of the brain and extends into the neck and back region. It forms a primary communication channel between the brain and the body.

Injury to the delicate spinal cord or its surroundings is known as a spinal cord injury.

What is the prevalence of spinal cord injury?

The World Health Organization estimates that about 2-5 lakh people suffer a spinal cord injury every year, primarily attributed to accidents or trauma. A spinal cord injury increases the risk of death by 2-5 folds in the general population, making it a serious medical issue.  The prevalence of spinal cord injuries is estimated to be about 1.5 million in India, with an increase of 20,000 cases, year on year.

What causes spinal cord injury?

The most common cause of spinal injury is trauma owing to,

  • Vehicular or road accidents
  • Falls
  • Violence
  • Sports injury

Causes of spinal injury, other than trauma include:

  • Cancers
  • Arthritis
  • Infections
  • Deterioration of the spine
  • Congenital disabilities
  • Injury during birthing

Who are at risk of spinal cord injury?

Anyone who is at a higher risk for of injury is at high risk for spinal cord injuries.

  • People who have smaller than regular spinal cords are also at a higher risk for spinal cord injury
  • Engaging in risky behaviour, sportspersons and presence of a bone disorder may also increase the risk of spinal cord injury

What are the types of spinal cord injury?

Based on severity

  • Complete: A result of a severe injury leading to complete loss of sensation and movement below the site of injury
  • Incomplete: A result of injury leading to a partial loss of sensation and movement below the site of injury

Based on the part of the body affected

  • Tetraplegia: A severe type of spinal cord injury wherein there is a loss of sensation, function or movement in the head, neck, arms, hands, shoulders, upper chest or legs, impacting daily functions.
  • Paraplegia: Loss of sensation, function or movement in the legs or lower parts of the body.
  • Triplegia: Loss of sensation and movement in one arm and both legs, and is usually seen in incomplete spinal cord injury.

types of spinal cord injury

The American Spinal Injury Association (ASIA) classifies spinal cord injuries into the following types

  • ASIA A: A complete spinal cord injury with complete loss of movement and sensation
  • ASIA B: A complete spinal cord injury with complete loss of movement
  • ASIA C: An incomplete spinal cord injury with limited movement preserved, with less than half muscles are unable to lift extremities
  • ASIA D: An incomplete spinal cord injury with limited movement preserved, with more than half muscles are unable to lift extremities
  • ASIA E: Normal movement and sensation preserved

Spinal concussions: A trauma to the spinal cord leading to temporary dysfunction of the spinal cord. They can be complete or incomplete and generally resolve in 24 to 48 hours. Football players are prone to head collisions, leading to neck injuries and hence may be frequent victims to spinal concussions.

What are the symptoms of spinal cord injury?

The symptoms of spinal cord injury depend on the type, degree and level of injury and hence can be extremely variable. However, some of the common symptoms that suggestion a spinal cord injury include:

  • Loss of movement
  • Loss or tingling sensation, including the ability to feel heat, cold and touch
  • Loss of bowel or bladder control
  • Exaggerated muscle movement or spasms
  • Changes in sexual function, sexual sensitivity and fertility
  • Pain or an intense stinging sensation
  • Difficulty breathing or coughing
  • Balance issues

How is spinal cord injury diagnosed?

The symptoms of a spinal cord injury may not be evident immediately post the damage and hence needs immediate medical attention to identify the problem and its extent.

The immediate step is the assessment of breathing and pulse rate, to ensure the patient is stable. Commonly, a comprehensive medical history and physical examination help identify the areas of movement and sensation loss. The area of the spinal cord injury is generally immobilised using medical equipment like collars.

Moreover, a few tests help take pictures of the site of injury and confirm the condition. They help in identifying fractures, abnormalities, blood clots and masses among others.

The routine assessments include:

  • Blood test
  • X-Ray
  • CT scan
  • MRI scan

When to seek emergency care?

Overall, spinal cord injury is a critical medical emergency and begins at the site of the accident. Any damage to the head and neck region need immediate medical attention to check for spinal cord injuries. Immobilisation is the key to the overall management and is taken care of by the emergency personnel with the help of a neck collar.

to seek emergency care

It is essential to evaluate for spinal cord injury at the earliest because:

  • The symptoms may manifest later on and worsen the injury
  • The damage may get severe with every passing second, exacerbating the injury
  • Immediate treatment may help reduce the possibility of a complication and expected early recovery

The treatment in the hospital begins with:

  • Maintaining and stabilisation breathing and heart function
  • Preventing shock
  • Immobilisations
  • Avoiding complications like breathing failure and heart damage

How is spinal cord injury treated?

The overall treatment plan depends on:

  • Age, overall health, and medical history
  • The extent of the spinal cord injury
  • Type of spinal cord injury
  • The extent of the spinal cord injury

The nature of treatment for spinal cord injuries is aggressive and long-lasting. It includes a long duration of ICU care, surgeries, use of bladder catheters, ventilator care, feeding tubes, among others.

The first step to treatment includes immobilization of the spine to avoid any further injury to the spinal cord. It is primarily carried out at the accident site by paramedics. Vitals, like breathing and heart health, is checked and managed.

The person is also checked for the possibility of other injuries and is generally taken care of in the intensive care unit (ICU). Traction or collars are used to align and uphold the spine. The other essential of care includes blood pressure stabilization, heart function, lung function, preventing infections, maybe in the treatment plan.

Surgeries are also an important treatment option for spinal cord injuries. It is dependent on the type, extent and degree of the injury. It also dictates the possible outcome during recovery. Sometimes, surgery may not reverse the damage but helps in preventing worsening of the injury.

Follow-ups are generally a part of the treatment plan to monitor progress and prevent complications. Complete spinal cord injuries may not lead to the recovery of functions when compared to incomplete spinal cord injuries. However, it is imperative to know that full recovery is rare with spinal cord injuries and often associated with a lifelong physical and emotional impact. It is also known to be fatal.

What are the complications of spinal cord injury?

Spinal cord injuries are associated with multiple complications. Hence, long term treatment may be required post fixing of the damage. Some of them include:

  • Urinary tract infections
  • Loss of bladder control
  • Loss of bowel control
  • Pressure ulcers due to long term immobilization
  • Pneumonia
  • Chronic pain
  • Depression
  • Loss of skin sensation
  • Development of blood clots
  • Life-threatening rise of blood pressure
  • Swelling of extremities
  • Muscle problems
  • Impact on sexual health

Complete tetraplegia increases the risk of complications such as pneumonia, pressure ulcers and clots in the extremities.

What is the role of rehabilitation in managing spinal cord injury?

The process of recovery after a spinal cord injury is long and draining. Early rehabilitation helps optimize recovery and support physical and physiological health. The program generally includes a team of healthcare professionals, along with the family members to ensure the well-being of the patient.

  • Electrical stimulation devices: These are advanced products that use electrical stimulators to control hand or leg functions, helping people regain some ability to walk, hold on to items, etc.
  • Robotic gait training: A robotic instrument used to help regain walking 
When to expect recovery?

The nature of the injury makes it difficult to provide duration to recovery. However, depending on the condition, recovery starts 1 week to 6 months after the injury. However, this can extend up to 2 years or more, and still have unfavourable outcomes
