Nonunion-Malunion of Proximal Humerus Fracture

Fractures may not heal correctly for a variety of reasons, ranging from smoking and poor nutrition to improper early activity and infection. This condition may occur with or without surgical intervention. A nonunion indicates a lack of healing while a malunion is healing of the fracture in improper alignment. Without intervention, a majority of nonunions and some malunions will continue to cause pain and physical limitations.
