Traumatic instability of the elbow - anatomy, pathomechanisms and presentation on imaging. Current concepts in elbow fracture dislocation. The article describes the radiological findings and outlines the management principles in complex elbow fracture-dislocation injuries. In trans-olecranon fracture-dislocation, there is significant disruption of the greater sigmoid notch and the olecranon, with various involvement of the coronoid and the proximal ulna. The latter are commonly associated with radial head fractures and lateral ligamentous injury, and have a worse prognosis. These can be divided into apex anterior or apex posterior variants. Monteggia fracture-dislocation injuries demonstrate proximal ulnar fracture (with possible involvement of the olecranon and the coronoid) and radial head dislocation. In posteromedial fracture-dislocation, there is a fracture of the anteromedial facet of the coronoid, typically with proximal avulsion of the lateral collateral ligaments (± injury to the posterior bundle of the ulnar collateral ligament). A posterolateral fracture-dislocation with radial head and coronoid anterolateral facet fractures is termed a terrible triad injury. Posterolateral fracture-dislocation is characterized by a radial head fracture (± anterolateral coronoid fracture) and typically capsuloligamentous disruption (lateral collateral ligaments injury is the most common). The most common types are posterolateral, posteromedial, Monteggia type (and variants), and anterior trans-olecranon fracture-dislocations. Surgical intervention is guided towards restoring joint stability, allowing early mobilization and preventing long-term joint stiffness. Elbow fracture-dislocation is a complex injury which can lead to significant bony and soft tissue damage.
