What are the main types of soft-tissue injuries?

The main types of soft-tissue injuries include lacerations, abrasions, avulsions, puncture wounds, and contusions, making this the correct choice.

Lacerations are tears in the skin that can vary in depth and severity, often resulting from sharp objects. Abrasions are shallow injuries to the outer layer of the skin, commonly occurring from friction against a rough surface. Avulsions involve the tearing away of skin or tissue from its normal position and can be particularly serious since they may expose underlying tissues. Puncture wounds are deep, narrow wounds caused by pointed objects penetrating the skin, leading to a higher risk of infection. Contusions, or bruises, occur when blood vessels are damaged due to impact, causing localized bleeding under the skin.

The other options contain injuries that either do not classify as soft-tissue injuries or include additional types of injuries that fall outside this category. For instance, fractures and dislocations pertain to bone injuries, while strains and sprains focus on muscle and ligament injuries, respectively. Thus, they do not align with the primary types of injuries classified under soft tissues.
