| closed (simple) fracture | Fracture with skin intact |
| open (compound) fracture | Skin integrity is interrupted. Higher chance of infection. |
| Oblique fracture | Fracture line is at a 45 degree angle to the bone. |
| Spiral fracture | Fracture that curves around the bone. |
| Avulsed fracture | Fracture pulls bone and other tissues away from the point of attachment. |
| Comminuted fracture | The bone breaks into many pieces. |
| Compressed fracture | The bone is crushed. |
| Impacted fracture | The broken bone ends are forced into each other. |
