V44: Car occupant injured in collision with heavy transport vehicle or bus

The V44 group of conditions refers to various forms of injuries suffered by occupants of cars during a collision with a heavy transport vehicle or bus. These accidents can result in a multitude of injuries that can range from minor abrasions to severe, life-threatening injuries. The accident's impact force, site and angle, in conjunction with factors like the car's speed, occupant's age, health, and seatbelt use, determine the extent of injuries. Commonly observed injuries include whiplash, fractures, head injuries including traumatic brain injuries, injuries to the spine, internal organ damage, soft tissue injuries, and psychological trauma. The condition's severity and progression largely depend on the specific injuries incurred and their immediate management. The system primarily affected would depend on the specific injury type but can include the skeletal, nervous, and cardiovascular systems, and the integumentary system (skin, hair, nails).
