Frakturen

Typ 1A simple separation of the posterior rim of the vertebra. (...) the fragment appears to be an arcuate structure in the spinal canal. (...) there is no osseous defect in the posterior part of the vertebral body because so little bone is present in the fragment.
  
Typ 2An avulsion fracture of the posterior rim of the vertebra body, including the overlying cartilage of the anulus fibrosus. The fragment is not arcuate and is rather thick compared with that in a Type-I fracture. (..)
  
Typ 3A small fracture, posterior to an irregularity in the cartilage of the end-plate. (...) there is a round defect in the bone adjoining the fracture site. The osseous defect in the vertebral body represents fragment and the cartilaginous irregularity.
