Surgical neck fracture of the humerus is a common injury in elderly people and usually successfully unites following adequate conservative or surgical treatments. Thus, the nonunion of the proximal humerus is not very common, but is difficult to treat once it develops.
We present a case of surgical neck nonunion of the left humerus for which prosthetic replasement was performed. Although she was unable to hold anything in her left arm or elevate left shoulder due to a severe pain before prosthetic replacement, she could hold a one kg dumbbell five months after the operation without pain.
