volkmann’s ischaemic contracture cause
damaged brachial artery
volkmann’s ischaemic contracture
The patient is unable to extend the hand at the wrist even when extensors are activated.
effect of volkmann’s ischaemic contracture on flexor compartment
Forearm muscles in the
flexor compartment become
short and fibrotic
