Neurovascular compromise is often associated with injury to which articulation?

• A. Articulation of the distal radius with the proximal ulna
• B. Articulation of the knee joint
• C. Articulation of the distal humerus with the proximal ulna
• D. Articulation of the shoulder joint

Answer: (C)

Neurovascular compromise occurs when a fracture or dislocation injures the blood vessels and nerves supplying a limb. The elbow is a key area because the major neurovascular bundle—the brachial artery and several important nerves (including the median nerve)—runs very close to the distal humerus. When there is a fracture-dislocation at the distal humerus with proximal ulna involvement, these structures are at high risk of being damaged, which can lead to a weak or absent pulse, cool or pale hand, numbness, or motor weakness. Other joints can have nerve or vessel injury, but the elbow’s anatomy places the brachial artery and nearby nerves in immediate danger with this type of injury, making neurovascular compromise a classic concern here.
