An example case of a right proximal humerus fracture in a 54-year-old woman treated with intramedullary nail fixation. (A) X-ray image showing the fractures in the anatomical neck of the right humerus and the greater tuberosity, as well as valgus cottage and greater tuberosity displacement; (B) CT scan of the fracture and displacement; (C) Postoperative anteroposterior X-ray image showing good reduction of the anatomical neck and greater tuberosity fracture. The proximal and distal interlocking screws satisfactorily positioned; (D) Anteroposterior X-ray image of the right humerus anatomical neck and greater tuberosity showed good healing, no loosening of internal fixation, and no displacement of fracture at one year postoperatively.
