Any fracture to the leg or arm should be considered a medical emergency. The arm or leg should not be moved until help arrives. Don't try to straighten or adjust the bone. This can damage the bone and injure nearby blood vessels and nerves. If an open wound is present, cover it with a clean cloth to keep it from getting dirty and to help prevent infection.

Here is what will happen in the ER: 

• A healthcare provider will ask about your injury and examine you carefully.

• Any wounds you have will be cleaned.

• X-rays of the injured area will be taken.

Treatment depends on where the bone is broken and whether there is an open wound. If you have an open wound, you may receive IV antibiotics and have the wound flushed with sterile water. Most fractures are treated in two stages:

• Reduction. The bone is put back into its proper position, if needed.

• Immobilization. The bone is held in place so it doesn't move as it heals. For many arm or leg fractures, this is done with a splint or cast. Serious or compound fractures may need surgical repair. In that case, you will be referred to a bone specialist (orthopedic surgeon).

Here is what to look for:

• The leg or arm is crooked

• A joint looks out of place

• A bone sticks out (protrudes) from the skin

• Weight can't be put on the leg or arm

• The limb swells or is very painful

• The limb is numb or tingles

• A popping or snapping was heard during the injury

• Bruising
