Antegrade Unreamed Locked Intramedullary Nailing in Open Fractures of Shaft of Humerus.

Abstract

Open fractures of shaft of humerus have been treated conservatively as well as operatively. Plate osteosynthesis has been considered as the gold standard treatment. Intramedullary nailing also has same success rate in closed fractures. The results of 30 open fractures of shaft humerus fixed with locked unreamed antegrade intramedullary nailing were evaluated. The purpose of the study was to evaluate the role of locked intramedullary nailing in open fractures of shaft humerus in terms of bone union, secondary procedure required, complication, shoulder dysfunction and infection. Of consecutive 365 humeral shaft fractures, 63 fractures were open. Thirty-two patients were operated with plate osteosynthesis, while 31 patients who were treated with locked unreamed intramedullary nails fulfilling the inclusion criteria entered the study. Twenty eight of thirty patients united in mean duration of 10.5 weeks. There were two non-unions both of them united with bone grafting and plate osteosynthesis. Seven patients had superficial infection which healed with antibiotic course, while two patients had deep infection, which healed with repeat debridement. Eleven patients had preoperative radial nerve palsy, nine of which healed completely in average of six months. Twenty eight patients had excellent functional outcome at final follow-up while two patients had good outcome. Antegrade nailing is associated with good union rates and low infection rates and is a good option in open fractures and in polytrauma patients.
