Cast Care: Why You Need a Cast
Bones can break anywhere in the body. Casts are often used for fractures in the hands, arms, legs, or feet. There are many types of fractures. But all fractures heal the same way: New bone grows to connect the broken pieces. A cast holds broken bones in place while they heal.
How Bones Break
Depending on the injury, bones can break in different ways. These are the most common types of fractures. (You may have a fracture that's not shown here.)
Bone fragments (pieces) are lined up.
Bone fragments are not lined up.
The bone is broken into three or more pieces.
The bone breaks through the skin. (A fracture that doesn't break through the skin is a closed fracture.)
The bone bends, but may not break all the way. This happens most often in children, whose bones are softer and still growing.
