Study Notes

Ruedi-Allgower Classification Overview

  • Pilon fractures are classified as intraarticular fractures.
  • The classification is based on the degree of articular comminution and the displacement of fragments.

Ruedi-Allgower Types

  • Type 1: Non-displaced and non-comminuted intraarticular fracture.
  • Type 2: Displaced but not comminuted intraarticular fracture.
  • Type 3: Comminuted and displaced intraarticular fracture.

Pilon Fractures Explained

  • A pilon fracture refers to an intraarticular fracture of the weight-bearing dome of the distal tibia.
  • These differ from ankle fractures which involve the malleoli and typically do not affect the weight-bearing surface.

Diagnostic Imaging

  • Plain x-rays are insufficient for diagnosing pilon fractures; advanced imaging techniques are required.

Surgical Goals for Pilon Fractures

  • Focus on maintaining fibular length and stability.
  • Restore the integrity of the articular surface.
  • Stabilize the distal tibia and consider bone grafting when necessary.
  • Use of internal fixation is not universally applicable; circular frames may be considered.

Surgical Products for Pilon Fractures

  • Various products available include:
    • Evos Small
    • Evos Mini
    • 4.0 Cannulated Screws
    • Small Cannulated Screws
    • Taylor Spatial Frame
    • Jet-X Large
    • Jet-X Mini
    • ILIZAROV system
