The outcome of interlocking nailing of humeral shaft fractures, a one year hospital based study

Abstract

Background: The outcome of interlocking nailing of humeral shaft fractures is controversial Variations in implants, operative technique and follow-up parameters hinder comparative studies. The aim of this investigation was to evaluate the humeral nailing system according to clinical results, and to recognise advantages and disadvantages of interlocking. Methods: A total of 30 humeral shaft fractures were treated with an Antegrade interlocking humeral nail. Results: At 12-month follow-up, bone consolidation was present in 30 cases; in 1 case complications developed. Constant shoulder score, mean Morrey elbow score, SF-12 physical score or SF-12 mental score. Conclusion: Antegrade interlocking nailing of humeral shaft fractures can result in good functional outcome and unimpaired quality of life. Compression interlocking can minimise the fracture gap and increase the biomechanical stiffness. Potential disadvantages of compression interlocking include possible bending or loosening of the locking screw in the dynamic oblong hole.
