Ruedi-Allgower Classification Flashcards

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.
