Posterior olecranon fracture dislocation

Apex posterior fractures of the proximal ulna that enter the ulnohumeral joint typically feature fracture of the coronoid that is usually multifragmentary, an associated radial head fracture and posterior subluxation of the radial head, and about half have avulsion of the origin of the lateral collateral ligament from the lateral epicondyle.
