What is the definition or description of: humerus fracture?

Broken arm bone: The humerus is the bone of the upper arm that goes from your shoulder to your elbow. A fracture is a break in the bone, which may or may not involve one of the joints (shoulder or elbow). An orthopaedic surgeon can look at x-rays of humerus fracture to determine whether it needs surgery. Some fractures of the humerus heal well on their own, while others do much better with an operation.

Arm bone break: It is a fracture (bone break) of the upper arm bone. The humerus is the bone that connects to the shoulder (through part of the shoulder blade) at one end, the elbow (through the two bones of the forearm, the ulna and the radius) at the other. The humerus can be fractured anywhere along its length.
