The distal humerus features several important bony landmarks, including the medial and lateral epicondyles, the trochlea, and the capitulum, all of which play key roles in elbow function. The epicondyles serve as attachment points for the forearms flexor and extensor muscles, while the trochlea articulates with the ulna and the capitulum with the radius to form the hinge and pivot components of the elbow joint. These structures help guide the movement of the forearm and allow both flexion-extension and rotation. Their exposed location makes them vulnerable to fractures and provides clear reference points in orthopedic assessment.
