The nurse should be concerned about the Compartment syndrome which requires emergency measures.
When adjacent bones are separated from the joint, their normal use is disturbed and their shape is distorted.
Trauma can disrupt the local blood supply to structures such as articular cartilage, causing degeneration, chronic pain, and limited movement.
Compartment syndrome is a condition in which structures such as tendons and nerves are compressed in an enclosed space. Fractures of the humerus can also be displaced, but are not the result of a circulatory disorder.
Muscle cramps can occur around the fracture site but do not cause circulation problems.
The humerus is the shoulder bone located between the elbow and shoulder. Its main function is to support shoulder and various arm movements.
