Complete vs. Incomplete Spinal Cord Injury: What the Difference Means for Recovery and Your Claim
What Is the Difference Between a Complete and Incomplete Spinal Cord Injury?
A complete spinal cord injury means no motor or sensory function remains below the level of the injury. An incomplete spinal cord injury means some movement or feeling is still present below the injury. Because some function remains, incomplete injuries have a wider range of possible recovery outcomes. That same uncertainty is why they are often harder to value in an injury claim.Key Takeaways about Complete and Incomplete Spinal Cord Injuries
- A complete spinal cord injury involves no motor or sensory function below the injury level, including in the lowest part of the spinal cord.
- An incomplete spinal cord injury involves some preserved movement or sensation below the injury level.
- Doctors classify spinal cord injuries using the ASIA Impairment Scale, which runs from A, a complete injury, to E, normal function.
- Incomplete quadriplegia affects all four limbs to some degree, while incomplete paraplegia affects the legs and lower body.
- Insurers often dispute the future-care costs in incomplete spinal cord injury claims because recovery is harder to predict.
What Is a Complete Spinal Cord Injury?
A complete spinal cord injury means there is no preserved movement or feeling below the level of the injury. Doctors confirm this by testing the lowest segments of the spinal cord, known as S4 and S5, near the base of the spine. When no sensation or muscle control remains, even at that lowest level, the injury is classified as complete. The National Institute of Neurological Disorders and Stroke explains that the level of the injury largely determines which parts of the body are affected. Early classification can change. In the first days after an injury, swelling and a temporary condition called spinal shock can hide function that returns later, so doctors often repeat the exam over time.What Is an Incomplete Spinal Cord Injury?
An incomplete spinal cord injury means some function below the injury level remains. A person may be able to feel parts of the body they cannot move, or may have some movement with reduced strength. Incomplete injuries vary widely. Two people with the same diagnosis may have very different abilities, and each person’s recovery can follow its own path.Common Types of Incomplete Spinal Cord Injuries
Doctors often describe incomplete injuries by the pattern of function that remains:- Central cord syndrome: The arms and hands are usually weaker than the legs. It often follows a neck injury from a fall or a rear-end crash.
- Brown-Séquard syndrome: One side of the body loses strength, while the other side loses the ability to feel pain and temperature.
- Anterior cord syndrome: Movement and pain sensation are affected, while the sense of touch and body position may remain.
- Posterior cord syndrome: Balance and position sense are affected, while strength may be preserved.
The ASIA Impairment Scale Explained
Doctors use the ASIA Impairment Scale, created by the American Spinal Injury Association, to grade how severe a spinal cord injury is. The grade comes from a detailed exam of strength and sensation at specific points on the body. The scale has five grades:- ASIA A (complete): No motor or sensory function is preserved in the lowest sacral segments.
- ASIA B (sensory incomplete): Sensation is preserved below the injury, but there is no motor function.
- ASIA C (motor incomplete): Some motor function is preserved, but most key muscles below the injury are too weak to move against gravity.
- ASIA D (motor incomplete): At least half of key muscles below the injury can move against gravity.
- ASIA E (normal): Sensation and motor function test as normal.
Incomplete Quadriplegia: What It Means
Incomplete quadriplegia, also called incomplete tetraplegia, results from an injury to the neck portion of the spinal cord. It affects the arms, hands, trunk, and legs to some degree, but some function remains below the injury. A person with incomplete quadriplegia might have limited hand function but some ability to stand, or might have sensation throughout the body with weakness in all four limbs. The higher the injury in the neck, the more of the body it may affect. Care needs can include physical and occupational therapy, adaptive equipment, home changes, and help with daily tasks. These needs often change as recovery progresses. Neck injuries of this kind often come from high-speed crashes on roads like I-275 and I-4, from motorcycle collisions, or from diving accidents. They can also follow falls, especially for older adults, whose spines may already have age-related narrowing.Incomplete Paraplegia: What It Means
Incomplete paraplegia results from an injury to the middle or lower part of the spinal cord. Arm and hand function are usually preserved, while the trunk, legs, and sometimes bladder and bowel control are affected. Some people with incomplete paraplegia regain the ability to walk with assistance, while others use a wheelchair for longer distances. The MedlinePlus spinal cord injury overview from the National Library of Medicine offers more background on treatment and rehabilitation. Every case is different. A rehabilitation team can explain what a specific diagnosis may mean for daily life. Why Incomplete Spinal Cord Injury Claims Are Often Disputed
Incomplete spinal cord injury claims are often contested because nobody can say for certain how much function will return. That uncertainty affects how medical costs, lost income, and future care needs are valued. A complete injury tends to have a more predictable long-term picture. With an incomplete injury, the insurer may argue that improvement is likely, while your doctors may see lasting limits and ongoing needs.The Role of a Life Care Plan
A life care plan is a detailed report, usually prepared by a medical or rehabilitation professional, that estimates the care someone will need over their lifetime. It can include therapy, equipment, medications, home changes, and attendant care. Florida law also shapes how medical costs are presented. Section 768.0427 of the Florida Statutes, passed in 2023, limits the evidence juries can see about medical expenses, which makes careful documentation of future care even more important.Lost Earning Capacity
Incomplete injuries also raise hard questions about work. A person may be able to return to some kind of job, but not the one they had, or not full-time. Lost earning capacity means the income a person can no longer earn over their working life because of the injury. Vocational consultants and economists often help show what that loss looks like in real numbers. A Tampa spinal cord injury lawyer works with treating doctors and life care planners to build a clear, supported picture of what recovery will require.How Do Insurers Challenge Future-Care Costs?
Insurers often challenge future-care costs by arguing the injured person will recover more than expected. Before representing injured people, Mickey Keenan represented insurance carriers, so we know how these arguments are built. Common tactics include:- Hiring their own medical reviewer to predict a better recovery.
- Pointing to early progress in therapy as proof that future care is not needed.
- Challenging the cost of home health aides, equipment, or home changes.
- Arguing that care could be provided more cheaply or by family members.
- Delaying settlement talks in hopes that recovery will reduce the claim.
What Affects Spinal Cord Injury Settlement Value?
Spinal cord injury settlement value depends on the specific injury, the losses it causes, and the insurance available. No two cases are the same, and no honest lawyer can promise a number at the start. Factors that often matter include:- The level of the injury and its ASIA grade.
- The cost of medical treatment, both past and future.
- Lost wages and reduced ability to work.
- The effect on daily life, independence, and relationships.
- The available insurance coverage and who was at fault.
Spinal Cord Injuries and Other Injuries That Often Occur With Them
The same force that damages the spinal cord can injure other parts of the body. A car crash, fall, or boating accident may also cause fractures, internal injuries, or a traumatic brain injury. Brain injuries can be missed at first when doctors focus on the spine. Memory problems, mood changes, or trouble concentrating after a crash deserve a closer look. Documenting every injury matters. Each one adds to the care needed and the losses the injured person faces.
