title: Open fractures of the humerus treated with external fixation.
abstract: Twenty-three patients with open fractures of the humerus who had been treated with immediate external fixation were reviewed retrospectively. Eighteen patients had adequate followup and were included in this study. Four patients (22%) had Gustilo and Anderson Grade I injury; 1 (5%), Grade II; and 13 (72%), Grade III (1 IIIA, 2 IIIB, and 10 IIIC). Fourteen patients (78%) had associated neurologic injury, of which 9 involved multiple nerves. A unilateral external fixation frame with half pins proximal and distal to the fracture site was used in all but 1 case. In 8 patients (44%) with distal humerus fractures, the external fixator crossed the elbow joint. All upper extremities in this series were salvaged. The duration of external fixation averaged 11 weeks. Complications included 3 malunions, 1 delayed union, 8 (44%) pin tract infections, 2 pin tract sequestrum formation, and 2 late fractures after removal of the external fixator. At followup (average, 34 months), function was rated as good or excellent in 12 patients (70%). There were 1 fair and 4 poor results. External fixation of complicated fractures of the humerus allowed associated injuries to the nerves, arteries, and soft tissues to be treated adequately while maintaining skeletal stability.
