External fixation for the treatment of open fractures of the proximal humerus caused by firearms

Abstract

Nine patients with open fractures of the proximal humerus were treated using an external fixation device. All of them had grade III open fractures resulting from high-velocity missile and explosive injuries with massive foreign body contamination. Radial nerve injury was present in five and two multiply injuried patients with thoracic wall and abdominal viscera were present. There were no major arterial injuries. Chronic osteitis with fistula and sequestra developed in one. There were no nonunions and no refractures. Minor painless limitation of shoulder and elbow motion presented in all patient. Upper-third humeral open fractures due to firearms are a unique type of open fractures. They are usually highly comminuted therefore, stable fixation is difficult or impossible to achieve. On the other hand, the risk of infection is high following plate fixation. External fixation allows adequate management of the soft tissue wounds, provides stable bone fixation and allows early mobilization of the shoulder and elbow.
