Sanders classification
Sanders Classification
The Sanders Classification (pronunciation: /ˈsændərz klæsɪfɪˈkeɪʃən/) is a medical classification system used to categorize fractures of the calcaneus, or heel bone, based on the number and location of fracture lines seen on computed tomography (CT) scans. It was developed by Dr. Richard Sanders, an orthopedic surgeon, in the late 20th century.
Etymology
The term "Sanders Classification" is named after its creator, Dr. Richard Sanders. The word "classification" (pronunciation: /klæsɪfɪˈkeɪʃən/) comes from the Latin classis, meaning "class", and facere, meaning "to make".
Classification System
The Sanders Classification system is divided into four types:
- Type I: Non-displaced fractures
- Type II: Fractures involving two parts, typically the anterior process and the posterior facet
- Type III: Fractures involving three parts, typically the anterior process, the posterior facet, and the calcaneocuboid joint
- Type IV: Fractures involving more than three parts
Each type is further subdivided based on the specific location and extent of the fracture.
