What is Volkmann's ischemia?

Volkmann's ischemia refers to a condition that results from a lack of blood flow to the forearm muscles, usually following an injury that compresses the blood vessels, particularly the brachial artery. This situation can lead to severe muscle ischemia and potential necrosis if not addressed quickly.

The correct answer highlights the mechanical blockage of the brachial artery, which is crucial because the obstruction prevents adequate blood flow. This blockage can occur due to various factors, such as swelling, tight bandaging, or fracture displacement, and if the pressure remains high, it can result in irreversible muscle damage.

Understanding this condition emphasizes the importance of recognizing symptoms and the need for prompt intervention to restore blood circulation and prevent long-term complications like muscle contractures or permanent dysfunction.
