Rare arm fracture…

This patient presented with arm pain after a fall.  The radiographs obtained showed a distal radius fracture along with a radial head fracture (irregularity and bone fragment seen at the radial head).

I haven’t seen this fracture pattern before.  I’m not sure if it can be classified as an Essex-Lopresti fracture (radial head fracture accompanied by dislocation of the radioulnar joint).  In looking at the radiographs I believe the radioulnar joint is still intact.  However, I’m wondering if the clinical principle of the Essex-Lopresti fracture is maintained:  is there a disruption of the interosseous membrane between the radius and ulna.  This disruption can lead to serious long-term disability including pain, loss of pronation, supination and extension range-of-motion (1).

Has someone out there seen this before?  Any pearls of wisdom regarding this fracture pattern?
