The Tile classification is a system of categorizing pelvic fractures based on fracture pattern,[1] allowing judgment on the stability of the pelvic ring.
| Tile Classification | 1 | 2 | 3 |

| B - rotationally unstable/vertically stable | Open-book external rotation injury | Young-Burgess lateral compression type internal rotation injury | Bilateral |
| C - rotationally and vertically unstable | Unilateral with intact contralateral side | Unilateral with incomplete contralateral side | Bilateral |
