title: Scapholunate dissociation from a fall on the elbow.
abstract: We report an undescribed mechanism of injury that caused scapholunate dissociation. Scapholunate dissociation has been previously described as resulting from a fall on the outstretched hand. In this case injury was caused by a fall on the elbow. The mechanism is compared to that of an axe head that is repositioned by butting the handle of the axe on the ground. Recognition of this mechanism may help in the diagnosis of this injury.
