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
