Sanders classification

Sanders classification is a system used in the medical field to categorize fractures of the calcaneus, or heel bone. This classification system is based on the number of fracture lines that are present in the posterior facet of the calcaneus, as seen on a CT scan. The Sanders classification system is widely used due to its ability to predict functional outcome and guide treatment.

Overview

The Sanders classification system divides calcaneal fractures into four types:

• Type I: Non-displaced fractures
• Type II: Fractures with two parts
• Type III: Fractures with three parts
• Type IV: Fractures with more than three parts

Each type is further divided into subtypes A, B, and C, depending on the location of the fracture lines.

Clinical Significance

The Sanders classification system is important in guiding the treatment of calcaneal fractures. Non-displaced fractures (Type I) are typically treated non-operatively, while displaced fractures (Types II-IV) may require surgical intervention. The number of fracture parts also correlates with the prognosis, with more parts generally indicating a worse outcome.
