Causes
Any fracture in elbow region or upper arm may lead to Volkmann's ischemic contracture but commonly caused due to supracondylar fracture of the humerus.
Volkmann's contracture results from acute ischaemia/necrosis of the muscle fibres of the flexor group of muscles of the forearm, especially flexor digitorum profundus and flexor pollicis longus which becomes fibrotic and short.
It is caused by obstruction on the brachial artery near the elbow, possibly from improper use of a tourniquet, improper use of a plaster cast, or compartment syndrome. It is also caused by fracture of forearm bones which cause profuse bleeding from major blood vessels of forearm.
