title: Nonunion of the humerus.
abstract: Under certain circumstances, fractures of the humerus may not heal. Some fractures experience delayed union and some develop nonunion despite improved methods of treatment. This chapter discussed nonunion and fracture fixation methods in the proximal, middle, and distal thirds of the humerus. Special circumstances were discussed, such as infection, nerve palsy, comminution, and electrical stimulation.
