Abstract
Proximal humerus fracture-dislocation is a rare condition that occurs mostly in young adults due to high energy trauma and about 60-79 percent of misdiagnosis is occurred in the first diagnosis. In this article, we present two patients with proximal humerus fracture-posterior dislocation the fractures of whom were diagnosed, but after the radiographic studies including x-ray and computer tomography (CT) scan, the posterior dislocation was misdiagnosed. In addition, complications, management, and avoidance of this misdiagnosis were discussed.
