The elbow joint, although non–weight-bearing, is among the most complex articulations in the human body (see Image. Ligamentous Anatomy of the Left Elbow, Anterior View). The primary articulation in this synovial hinge joint is between the distal humerus and proximal ulna, supplemented by connections between the proximal radius and humerus and between the proximal radius and ulna. The resulting 3 components—the ulnohumeral, radiohumeral, and proximal radioulnar joints—function together to permit flexion, extension, pronation, and supination. Numerous muscles from both the arm and forearm cross or attach to at least 1 element of the elbow complex, contributing to the high frequency of injuries observed in athletic activities. After the shoulder, the elbow is the 2nd most commonly injured joint in sports-related trauma.[1] A broad spectrum of conditions affects the elbow, including medial collateral ligament (MCL) tears, medial epicondylitis, distal biceps tendon ruptures, osteochondritis dissecans, olecranon bursitis, and pediatric radial head subluxation. The elbow also holds substantial surgical significance, with procedures such as ligament reconstruction, tendon reinsertion, arthroscopic debridement, osteochondral fixation, and bursectomy frequently employed to restore function or address persistent pathology. A deeper understanding of elbow anatomy, joint mechanics, and functional biomechanics allows clinicians to recognize injury patterns accurately, optimize diagnostic evaluation, and select appropriate therapeutic interventions.
