External dynamic fixation in fractures of the humerus: can it still be considered treatment of second choice?
The authors report 40 patients affected with diaphyseal fracture of the humerus treated by dynamic axial fixator (FAD Orthofix). Minimum follow-up was 2 years. A clinical and radiographic retrospective study was conducted with the purpose of verifying the validity of external fixation as treatment of choice in diaphyseal fractures of the humerus. The results were evaluated considering healing time, extent and type of complications, long-term clinical, radiographic and functional findings. Results were: excellent: 35; good: 2; fair: 2; poor: 1. Complications were: nonunione: 1; reimplantation of FAD screws: 1; 4 infections of the screw holes, 3 realignments due to secondary displacement, 1 re-fracture after removal of the implant. There were no iatrogenic lesions of the radial nerve, or infections of the fracture site. The authors conclude that this semi-invasive, versatile and well-tolerated method, may be considered a valid alternative to conservative treatment, or to internal fixation even in cases of single trauma, despite limits related to the degree of collaboration of the patient, particularly with regard to debridement of the screw holes and periodical clinical and radiographic monitoring.
