| Closed Fracture | simple fracture. a break in a bone but no open wound in the skin. |
| Open Fracture | compound fracture. a break in a bone, as well as an open wound in the skin. |
| Compression Fracture | caused by bone surfaces being forced against each other, as in the compression of one vertebra against another. |
| Impacted Fracture | occurs when a direct force causes the bone to break, forcing the broken end of the small bone into the broken end of the larger bone. |
