Minor crush injuries can usually be treated with basic first aid, such as cleaning and bandaging the wound. Medical treatment is needed for a more serious crush injury. This treatment is needed to prevent loss of function, restore circulation to the injured area, and prevent infection. An example of a minor crush injury is getting a finger caught in a door. A crush injury is more serious when it involves a large force, such as a foot being run over by a car.

The crush injury is cleansed with soap and water. If there is bleeding, pressure is applied to control the bleeding. Ice is applied. An x-ray is required to determine if the bone was damaged.

A tetanus shot should be given if the person has not had one in the past 10 years. Antibiotics may be given to prevent infection.

A severe injury may need surgery and even removal of the body part.
