AbstractThis level IV case series study prospectively evaluated patients with atrophic proximal humerus nonunions stabilised with a locking 90 degree blade plate. All patients were women with an average age of 69 years (range 56-78). Time from trauma to nonunion treatment averaged 23 months. Five patients had had previous surgical treatments. Two patients had a history of infection and one patient with active infection was reconstructed in two stages. Follow-up averaged 22 months (range 18-36); union was achieved in all seven cases after an average of 5.85 months. The DASH score at the last follow-up averaged 25 points and Constant score averaged 72.7 points. No patient required additional procedures. At the last follow-up all patients were free of infection, and there were no cases of avascular necrosis. The results with locked 90 degree blade plates in atrophic nonunions of the proximal humerus in adults were favourable in this series.
