A catastrophic injury is one that causes permanent, disabling, or life-altering harm. Examples can include traumatic brain injuries, spinal cord injuries, severe fractures, amputations, chronic pain conditions, or injuries requiring multiple surgeries and long-term care. These cases often involve future medical expenses, reduced earning capacity, and loss of normal life, so they require detailed evidence and careful damages planning.
