An Unusual Variant of a Floating Forearm Injury: A Case Report and Review.

Abstract

"Floating forearm" injuries, perilunate injuries, with an elbow dislocation, are rare and challenging to treat. We present the case of an unusual variant of a floating forearm injury, trans-scaphoid perilunate fracture dislocation and elbow dislocation, with a concomitant open both-bone forearm fracture after a fall from a ladder. Treatment involved irrigation and debridement of the forearm wound, open reduction and internal fixation of the forearm and perilunate injury, and closed reduction of the elbow. At final follow-up, he had returned to his previous occupation. Radiographs demonstrated fully healing fractures without evidence of osteonecrosis or degeneration. A review of the presentation, evaluation, and management of this rare injury pattern is provided.
