Radiological signs of a true lunate dislocation

Perilunate dislocations are high-energy injuries that are uncommon. The literature suggests that up to 25% of cases may be missed.1 ,2 Here we present an acute lunate dislocation in a young man who fell from a height of 12 feet onto an extended, outstretched right hand. Plain radiographs demonstrated classical signs of a perilunate dislocation (figures 1 and 2). He also sustained fractures of the radial and ulnar styloid, indicating a variant of a greater arc injury.3 Following a failed closed reduction the patient proceeded to open reduction and …
