Term
Volkmann's ischemia
Definition
occurs secondary to supracondylar fracture

a compartment syndrome
increased pressure due to swelling from the fracture leads to a lack of blood flow to the forearm

ischemia can be caused by edema within a fascia-surrounded compartment or by acute elbow flexion that compresses an artery against bone

IMMEDIATE ACTION: peripheral nerves can withstand 2-4 hours without blood flow - still regenerate

muscles can withstand 6 hours but can't regenerate

don't cast until 3-4 days to reduce swelling
