Patient selection: acute compartment syndrome of a lower extremity


Outcome: presence of necrotic muscle at fasciotomy


Frequency of muscle necrosis in study: 14%


Risk factors for muscle necrosis:

(1) open fracture (OR 2.8)

(2) crush injury (OR 3.1)

(3) soft tissue injury other than crush or blunt trauma (electrocution, burn, infection, hemorrhage) (OR 2.8)
