The Gehweiler classification divides fractures of the first cervical vertebra into five types. Type III is also refered to as Jefferson fracture. The classical Jefferson fracture is a four part fracture, where both the anterior and the posterior arch is fractured twice, but fractures with two or three fracture parts may also occur.
Type | Description |
---|---|
Type I | fracture of the anterior arch |
Type II | fracture of the posterior arch |
Type III | combined fracture of both the anterior and the posterior arch = Jefferson fracture |
Type IV | fracture of massa lateralis |
Type V | fracture of the transverse process |
