Simplified diagnostic algorithm for Lauge-Hansen classification of ankle injuries

Area of Science:

• Orthopedic surgery
• Radiology
• Biomechanics

Background:

• Ankle injuries follow a predictable pattern.
• Recognizing the injury mechanism is crucial for classification and treatment.
• The Lauge-Hansen classification system is a widely used method.

Purpose of the Study:

• To explain the Lauge-Hansen classification system based on trauma mechanisms.
• To demonstrate the sequence of ligament rupture and bone fractures.
• To provide a logical framework for understanding and treating ankle injuries.

Main Methods:

• Utilizing three-dimensional (3D) movies to visualize injury sequences.
• Analyzing the mechanism of trauma, including foot position and deforming force direction.
• Requiring specific radiographic views: anteroposterior, mortise, and lateral.

Main Results:

• The Lauge-Hansen system classifies injuries based on the mechanism of trauma.
• Understanding the sequence of events aids in accurate classification.
• Specific radiographic views and criteria are essential for classification.

Conclusions:

• The Lauge-Hansen classification provides a logical approach to ankle injuries.
• Mechanism of trauma is fundamental to understanding and classifying ankle injuries.
• 3D visualizations enhance comprehension of injury sequences and guide treatment.
