Which articulation is commonly linked to neurovascular compromise in the elbow region?

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

Answer: (C)

Neurovascular compromise at the elbow is typically tied to injuries of the elbow joint itself. The elbow hinge is formed where the distal end of the humerus meets the proximal ulna, with important structures like the brachial artery and median nerve passing close to this area. When a fracture or dislocation occurs at this distal humerus–proximal ulna articulation, these vessels and nerves are at risk, leading to changes in pulse, sensation, or motor function in the forearm or hand. The other options involve joints not located at the elbow (shoulder or knee) or parts of the forearm joint that don’t directly affect the elbow’s neurovascular contents. So the articulation between the distal humerus and proximal ulna is the one commonly linked to elbow neurovascular compromise.
