Ruedi-Allgower Classification (Tibial Pilon Fracture)
The Ruedi-Allgower classification of tibial pilon (plafond) fractures, by articular displacement and comminution, types I/II/III.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Ruedi-Allgower type
- II - displaced, minimal comminution
Result: Ruedi-Allgower type II: significant displacement of the articular surface with minimal comminution.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Type I
- Cleavage fracture of the articular surface without significant displacement.
- Type II
- Significant articular displacement, but minimal comminution.
- Type III
- Comminution and impaction of the distal tibial articular surface.
What you enter
- Ruedi-Allgower type
