Open reduction and fixation with a locking plate without bone grafting is a reasonable and safe option for treating proximal humerus nonunion.

Aim Of The Study: The aim of this study was to evaluate union rate and clinical outcome in patients with proximal humeral nonunions treated by open reduction and locking plate fixation without bone grafting.

Methods: From 2011 to 2016, nine patients were treated using open reduction and locking plate stabilization without bone grafting. They were examined both clinically and radiologically, with a mean follow-up period of 31 months.
