Simultaneous bilateral "floating arm" of the humeri: an uncommon presentation of a rare complex injury and review of the literature.

The timing of definitive fixation for simultaneous fractures of the humerus in polytrauma patient is controversial. We report on the management of a patient that sustained bilateral "floating arm" fractures of the humeri. When dealing with such injury patterns, it is important to always carry out stabilization of the humeral diaphysis first and afterwards to treat the sub-injury or over-injury fractures. Our patient healed after twelve weeks in both humeri. After seven years MEPS showed excellent and good results in the right and left arms, while UCLA scores proved excellent in both sides. We encountered no intraoperative and postoperative complications.
