The Essex-Lopresti injury pattern is the lesser known of the triad of forearm injuries (Monteggia & Galeazzi).
It follows the “rule of the ring” aka the life saver candy rule: You can’t break a life saver in just one place.
These injury patterns are frequently missed because our eyes are drawn to the fracture and miss the associated dislocation.
The Essex-Lopresti fracture pattern involves a fracture of the radial head with concomitant dislocation of the distal radio-ulnar joint (DRUG)
-With associated interosseous membrane disruption
Think of it as the Maisonneuve fracture of the forearm.
Mechanism: fall from height/high energy forearm trauma.
PE: Suspect if patient has significant tenderness at the DRUG with a radial head fx.
Patients have worse outcomes if injury is missed on initial presentation due to radial migration and instability.
Take home point: Remember the rule of the ring. Remember to exam the elbow with wrist injuries and the wrist with all elbow injuries
