Elbow dislocations are very common, particularly in the posterolateral variety. Closed reduction is usually easy. However, an irreducible elbow dislocation without associated fracture is rare. We report the case of a 21-year-old patient who presented with an isolated posterolateral irreducible elbow dislocation. Open reduction revealed the buttonhole radial head in the capsule and the complex ligaments. A significant protrusion of the radial head associated with a closed reduction failure is highly suspicious of an irreducible dislocation.
