Volkmann's ischaemia

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

This describes threatened tissue ischaemia and necrosis due to increased swelling within an unyielding osteofascial compartment in the arm or leg. It may result from a fracture, from infection, from prolonged immobilisation in a tight plaster cast or from muscle hypertrophy in athletes; arterial damage is not necessary.

Untreated, a vicious circle soon arises in which tissue swelling results in reduced tissue perfusion and in turn, tissue ischaemia. This results in further swelling, a further increase in pressure, and a further reduction in capillary blood flow. Necrosis develops within about 12 hours - nerve function may be recoverable in time but infarcted muscle is damaged permanently. Eventually, the dead muscle fibroses and shortens, and an ischaemic contracture results.

Note that a compartment syndrome may complicate up to 15% of open fractures.
