Crush injuries can lead to which condition?

• A. Ischemia
• B. Compartment Syndrome
• C. Hypovolemia
• D. Gangrene

Answer: (B)

Crush injuries can cause swelling and bleeding inside a closed muscle compartment. The fascia around the muscles doesn’t stretch much, so this swelling raises the intracompartmental pressure. When pressure becomes high enough, blood flow to the muscles and nerves is reduced, leading to ischemia. This pressure-driven injury is known as compartment syndrome. It’s the best answer because it specifically describes the rapid, pressure-related complication that crush injuries can cause; if not treated promptly, ischemia from the rising pressure can progress to muscle necrosis and, eventually, gangrene. Early signs include severe, out-of-proportion pain and pain with passive movement, with numbness or weakness developing later. In management, remove constrictive devices, immobilize the limb, monitor neurovascular status, and transport urgently for possible fasciotomy.
