Which of the following injuries are considered limb-threatening?

Limb-threatening injuries are those that pose a significant risk to the viability and function of a limb, often requiring urgent surgical intervention or aggressive management to prevent permanent damage or loss. Open fractures and compartment syndrome are examples of such injuries.

Open fractures, where there is a break in the bone that penetrates through the skin, can lead to infection and significant bleeding, compromising the limb's viability. The exposure of bone and soft tissues creates a pathway for bacteria, heightening the risk of complications like osteomyelitis.

Compartment syndrome is another serious condition characterized by increased pressure within a closed muscle compartment, which can restrict blood flow to the tissues. This lack of blood supply can result in irreversible muscle and nerve damage if not treated promptly. The swelling or bleeding that causes this increased pressure can occur due to various injuries, including fractures.

In contrast, contusions and sprains, minor dislocations, soft tissue injuries, infections, and even simple fractures are generally not considered limb-threatening. While they can be painful and may require medical attention, they typically do not pose the same immediate risk to limb viability as open fractures and compartment syndrome do. Recognizing these significant injuries is crucial in emergency settings to ensure proper and timely treatment.
