Crush injuries of the upper extremity.

Massive open wounds are treated conservatively to preserve all viable tissue. Closed crush injuries may require extensive fasciolysis and debridement to treat compartment syndrome. Meticulous cleansing is the primary treatment for open injuries. Compartment syndrome occurs when intracompartmental pressure impairs capillary function and jeopardizes tissue viability. Rhabdomyolysis associated with crush injuries may lead to renal failure.
