Blue frames indicate most common fracture patterns
| Classification | Description | Notes |
| Posterior Wall | Tectum intact, post wall fracture | Associated with posterior hip dislocations |
| Transverse/Posterior Wall | Sagittal tectum, post wall fractures | Associated with posterior hip dislocations |
| Transverse | Sagittal tectum fracture | |
| T-type | Sagittal tectum, obdurator ring fractures | |
| Both Column | Coronal tectum, obdurator ring fractures | Often quite complex
|
| Anterior Column/posterior Hemitransverse | Coronal with posterior sagittal tectum fractures, intact obdurator ring |
Account for most of the remainder of fractures |
| Posterior Column/Posterior Wall | Coronal tectum, obdurator ring, posterior wall fractures |
