Terrible Triad Elbow Injuries

Terrible Triad injuries of the elbow, a complex traumatic condition involving a posterior elbow dislocation, radial head fracture, and coronoid process fracture. They explain the anatomy of the elbow, highlighting the roles of bones and ligaments in maintaining stability. The texts detail the mechanism of injury, often a fall on an outstretched arm leading to a posterolateral rotatory force, and emphasize the progressive nature of ligamentous and osseous disruption from lateral to medial. Diagnosis relies on clinical examination and advanced imaging techniques like X-rays and CT scans, often guided by classification systems like Mason for radial head and Regan and Morrey or O'Driscoll for coronoid fractures. While non-surgical management is rare, surgical intervention is typically required to restore joint stability and facilitate early mobilization, with approaches involving fixation or replacement of fractured components and ligament repair(especially the lateral collateral ligament, and sometimes the medial collateral ligament). The sources also address common complications such as stiffness, heterotopic ossification, and instability, underscoring the importance of a multidisciplinary approach and timely surgical repair for optimal patient outcomes.
