Pediatric ankle injuries: utilizing the Dias-Tachdjian classification

Area of Science:

• Orthopedic Surgery
• Pediatric Radiology
• Skeletal Growth Research

Background:

• Pediatric ankle injuries can affect long bone growth due to distal tibial physis involvement.
• Understanding injury patterns is crucial for timely diagnosis and management.
• The distal tibial physis's closure influences adolescent fracture types.

Purpose of the Study:

• To present a simplified algorithm for applying the Dias-Tachdjian classification in routine radiographic interpretation of pediatric ankle injuries.
• To correlate injury patterns with foot position and force direction.
• To examine the impact of distal tibial physis closure on specific adolescent fractures like Tillaux and triplane fractures.

Main Methods:

• Review and simplification of the Dias-Tachdjian classification system for pediatric ankle fractures.
• Analysis of injury patterns based on foot position and force direction.
• Examination of radiographic features of Tillaux and triplane fractures in relation to physeal closure.

Main Results:

• The Dias-Tachdjian classification, adapted for a completely open physis, identifies four major injury patterns.
• A simplified algorithm aids in routine radiographic interpretation.
• Physeal closure significantly affects adolescent fracture patterns, including Tillaux and triplane fractures.

Conclusions:

• A simplified Dias-Tachdjian classification algorithm enhances the interpretation of pediatric ankle physeal injuries.
• Radiologists can better identify subtle physeal injuries and nondisplaced fractures.
• Accurate classification aids in determining appropriate surgical or conservative management for pediatric ankle fractures.
