Final answer:
The typical injury that happens at the elbow joint is a distal humerus fracture, which can occur from a fall onto the tip of the elbow. Immediate concern with these injuries is possible compression of the artery to the forearm due to swelling of the surrounding tissues.
Step-by-step explanation:
The typical injury that happens at the elbow joint is a distal humerus fracture. This occurs when a child falls onto the tip of the elbow, causing the olecranon of the ulna to be driven upward and resulting in a fracture across the distal humerus. These fractures can occur above both epicondyles (supracondylar fracture) or between the epicondyles, separating one or both of the epicondyles from the humerus (intercondylar fracture). Immediate concern with these injuries is possible compression of the artery to the forearm due to swelling of the surrounding tissues.
