Sanders classification system for the Calcaneal fracture
The Sanders classification is used for the intraarticular calcaneal fractures evaluations affecting the posterior facet of the calcaneus.
This Sanders classification is based on the number and location of the intraarticular fractures using the semicoronal CT images as follow:
| Description | Detail | Image | |
|---|---|---|---|
| Type 1 | No-displaced | ||
| Type 2 | Two part fracture | A- Lateral third |  |
| B- Central third |  | ||
| C- Medial Third |  | ||
| Type 3 | Three part fracture | AB- Involvement of the lateral and central apsects of the posterior facet of the calcaneus, |  |
| AC- Involvement of the lateral and medial apsects of the posterior facet of the calcaneus. |  | ||
| BC- Involvement of the central and medial apsects of the posterior facet of the calcaneus |  | ||
| Type 4 | more than three part fracture (four or more fragments) |
