Spinal Cord Injury

World Health Organization

The term ‘spinal cord injury’ refers to damage to the spinal cord resulting from trauma (e.g. a car crash) or from disease or degeneration (e.g. cancer). There is no reliable estimate of global prevalence, but estimated annual global incidence is 40 to 80 cases per million population. Up to 90% of these cases are due to traumatic causes, though the proportion of non-traumatic spinal cord injury appears to be growing.

Symptoms of spinal cord injury depend on the severity of injury and its location on the spinal cord. Symptoms may include partial or complete loss of sensory function or motor control of arms, legs and/or body. The most severe spinal cord injury affects the systems that regulate bowel or bladder control, breathing, heart rate and blood pressure. Most people with spinal cord injury experience chronic pain

Spinal cord injury is associated with a risk of developing secondary conditions that can be debilitating and even life-threatening—e.g. deep vein thrombosis, urinary tract infections, muscle spasms, osteoporosis, pressure ulcers, chronic pain, and respiratory complications. Acute care, rehabilitation services and ongoing health maintenance are essential for prevention and management of these conditions.

Spinal cord injury may render a person dependent on caregivers. Assistive technology is often required to facilitate mobility, communication, self-care or domestic activities. An estimated 20-30% of people with spinal cord injury show clinically significant signs of depression, which in turn has a negative impact on improvements in functioning and overall health.

Misconceptions, negative attitudes and physical barriers to basic mobility result in the exclusion of many people from full participation in society. Children with spinal cord injury are less likely than their peers to start school, and once enrolled, less likely to advance. Adults with spinal cord injury face similar barriers to economic participation, with a global unemployment rate of more than 60%.

Existing data do not allow for global cost estimates of spinal cord injury, but they do offer a general picture.

The level and severity of the injury have an important influence on costs--injuries higher up on the spinal cord (e.g. tetraplegia vs. paraplegia) incur higher costs.

Direct costs are highest in the first year after spinal cord injury onset and then decrease significantly over time.

Indirect costs, in particular lost earnings, often exceed direct costs.

Much of the cost is borne by people with spinal cord injury.

Costs of spinal cord injury are higher than those of comparable conditions such as dementia, multiple sclerosis and cerebral palsy.

Prevention

The leading causes of spinal cord injury are road traffic crashes, falls and violence (including attempted suicide). A significant proportion of traumatic spinal cord injury is due to work or sports-related injuries. Effective interventions are available to prevent several of the main causes of spinal cord injury, including improvements in roads, vehicles and people’s behaviour on the roads to avoid road traffic crashes, window guards to prevent falls, and policies to thwart the harmful use of alcohol and access to firearms to reduce violence.
