Researchers have reported a mortality rate of 47% for acute compartment syndrome of the thigh. [62] A study showed the fasciotomy rate for acute compartment syndrome ranges from 2% to 24%. [19] The key factor in acute compartment syndrome is the time to diagnosis and fasciotomy. [12] A missed or late diagnosis may require limb amputation to ...
