Terrible triad injuries of the elbow
- 51 Downloads
Terrible triad injury of the elbow is a complex injury that is classically defined as elbow dislocation along with fractures of the coronoid process of the ulna and the radial head. The injury is usually associated with typical soft-tissue disruptions (with common involvement of the lateral collateral ligament complex, elbow joint capsule, as well as the common extensor and flexor–pronator tendons) that are best understood in the context of injury mechanism as well as the role and relevance of the various elbow stabilizers. The goals of this article are to review the pertinent anatomy, mechanism of injury, classification and imaging of terrible triad injuries of the elbow with brief descriptions of treatment, and complications of this complex injury.
