<wrap hi>**C2 Vertebral Body Fracture Classification (Benzel)**</wrap>

<WRAP column 60%>

<wrap lo>
The Benzel classification divides fractures of the C2 (axis) vertebral body into three types based on the fracture plane and the associated stability.
</wrap>

<tabs>

<tab>🟩 Type I – Coronal Plane Fracture</tab>
  * Fracture line runs anterior to posterior.
  * Generally **stable**.
  * May include mild anterior compression.
  * Common treatment: **rigid cervical collar** or **halo vest**.

<tab>🟨 Type II – Sagittal Plane Fracture</tab>
  * Parasagittal fracture, often separating a **superior articular facet**.
  * Potentially **unstable**, especially if displaced or facet-involved.
  * May require **anterior C2–C3 fusion** or posterior instrumentation.
