A crushing injury of the arm can occur when an external object applies an excessive force to the arm, such as a heavy weight, a sharp object, or a blunt object.
A crushing injury of the arm is diagnosed by a physical examination and imaging studies, such as x-rays and MRI. The physical examination may reveal tenderness, swelling, deformity, and muscle atrophy.
The differential diagnosis includes fractures, dislocations, contusions, and ligamentous injuries.
Treatment depends on the severity of the injury and may include immobilization, surgical repair of fractures, and physical therapy.
The prognosis for a crushing injury of the arm depends on the severity of the injury and the promptness of treatment. Generally, the prognosis is good with prompt treatment.
