Table 2 Non-AO-type classification of major spinal injuriesa

From: Earthquake-related versus non-earthquake-related injuries in spinal injury patients: differentiation with multidetector computed tomography

Types of fractures Earthquake-related vertebral injuries (%) Non-earthquake-related vertebral injuries (%)
Teardrop 4 (13.33) 13 (27.08)
Occipital condyle 2 (6.67) 1 (2.08)
Jefferson fractures 1 (3.33) 5 (10.42)
Odontoid processes 5 (16.67) 10 (20.83)
Hangman's fractures 4 (13.33) 8 (16.67)
Lateral mass or anterior arch 4 (13.33) 3 (6.25)
Posterior arch or laminar fractures 10 (33.33) 8 (16.67)
Total 30 (100) 48 (100)
  1. aNon-AO-type classification represents classifications of major spinal injuries that cannot be classified by the grid 3-3-3 scheme of the AO fracture classification established by Magerl [6, 10].
