Types
There are
many types of catastrophic injuries, and they might affect one's quality
of life. Common ones include :

Traumatic
Brain Injuries (TBI):
when there is a violent jolt or blow to the head, it may cause traumatic
brain injury that one suffers from temporary brain function damage and
hence has developed certain disablements that include speech, memory,
and motor function
Spinal cord injuries(SCI): Spinal cord injuries usually result in a loss of limbs or sensation within the body part below the injury site. SCIs very often cause partial or complete paralysis, which hugely impacts personal independence.
Amputations: These are when a limb is removed entirely or partially due to serious trauma or medical necessity. Amputations can have a disastrous physical and psychological impact on an individual, which may make it hard for him to carry out his daily activities and enjoy things he used to enjoy.
Severe
Burns:
These can result in long-term physical and emotional scarring. They may
damage skin, underlying tissues, and even organs, thus requiring
countless surgeries, skin grafts, and reconstructive surgeries.
Multiple
Fractures:
In cases where severe fractures affect the major bones in one's body, it
may result in permanent loss of functionality and a reduction of
mobility and strength for long periods.
