What makes an injury catastrophic is the severity of its lasting effects on work, independent living, and ordinary daily activities, rather than the diagnosis alone.
Ohio does not use one universal catastrophic-injury label to determine eligibility in all personal injury claims, and even a severe diagnosis does not establish liability by itself.
Instead, the relevant evidence concerns the injury’s cause, prognosis, functional effects, future care needs, and legally recoverable losses.
Common types of catastrophic injuries include:
- Traumatic brain injuries: Brain damage involving lasting cognitive, behavioral, physical, or communication difficulties.
- Spinal cord injuries: Damage causing paralysis, impaired mobility, altered sensation, or other significant functional losses.
- Amputations: Loss of a limb requiring prosthetics, rehabilitation, and adaptation to daily activities.
- Severe burns: Injuries involving scarring, permanent disfigurement, contractures, or repeated surgery.
- Crush injuries and multiple fractures: Extensive damage that may cause chronic pain, impaired movement, or permanent disability.
- Other injuries with permanent effects: Neurological or orthopedic conditions that substantially limit independence or employment, even without one of the diagnoses above.
Traumatic Brain Injuries and Cognitive Changes
A traumatic head injury caused by a fall, blow to the head, or car crash can affect memory, concentration, judgment, communication, mood, sleep, and the ability to manage ordinary responsibilities.
The CDC identifies falls and other blows or jolts to the head as common causes of traumatic brain injury, while the National Institute of Neurological Disorders and Stroke describes effects that can persist after severe trauma.
A person may regain physical mobility yet continue to struggle with planning, attention, decision-making, or the demands of their previous occupation.
Neurological examinations, imaging, neuropsychological testing, rehabilitation records, and observations from family members may document those changes.
The extent of a brain injury should be evaluated through the person’s actual symptoms and functional limitations rather than an assumption that every concussion causes permanent damage.
Spinal Cord Injuries and Paralysis
Spinal cord damage can affect movement and sensation, as well as bladder, bowel, respiratory, or other bodily functions.
The effects vary according to the location and severity of the injury, and some people retain substantial movement while others experience permanent paralysis.
The National Spinal Cord Injury Statistical Center estimates more than 18,000 new traumatic spinal cord injuries each year in the United States.
According to NINDS, rehabilitation may involve physical and occupational therapy, adaptive technology, mobility equipment, and vocational support.
Medical and rehabilitation records can help establish the likely duration of limitations, including whether the person needs recurring treatment, personal assistance, or accessible transportation.
Amputations, Severe Burns, and Other Permanent Injuries
An amputation may require prosthetic devices, replacement equipment, physical therapy, treatment for residual-limb complications, or modifications to the person’s home or vehicle.
Severe burns caused by fires, explosions, or other hazards can produce lasting scarring, painful contractures, limited range of motion, and psychological distress.
A 2024 study commissioned by the Amputee Coalition estimated approximately 465,000 annual limb-loss cases using 2016–2021 insurance claims, including amputations caused by disease rather than accidents.
Multiple fractures, significant nerve damage, and crush injuries may also cause chronic pain or permanent restrictions on movement and employment.
Treatment histories, specialist opinions, rehabilitation progress, and functional assessments can establish the specific long-term consequences without assuming that everyone with the same diagnosis needs identical care.
