A
Olecranon fracture
B
Coronoid process fracture
C
Medial epicondyle avulsion
D
Distal humerus intercondylar fracture
Explanation:The correct option is 'b'. The terrible triad of the elbow involves a posterior elbow dislocation associated with fractures of both the radial head and the coronoid process. This injury pattern is highly unstable as it disrupts primary static stabilizers (ulnohumeral joint/coronoid, radiocapitellar joint/radial head) and the lateral collateral ligament complex, requiring meticulous surgical repair to restore stability.
