  • Summary
  • Epidemiology
  • Etiology
  • Anatomy
  • Letournel Classification
    • Judet and Letournel
      • most common referenced classification system
        • classifed as 5 elementary and 5 associated fracture patterns
      • most common fracture patterns
        • younger
          • posterior wall
          • transverse fracture "family"
            • transverse
            • T-type
            • transverse + posterior wall
        • elderly
          • anterior column (e.g., quadrilateral plate fractures)
          • anterior column, posterior hemitransverse
          • assoicated both column fractures
        • Elementary patterns
        • Illustration
        • AP
        • Obturator ob.
        • Iliac ob.
        • CT
        • Comments
        • Posterior wall
        • Most common
        • "gull sign" on obturator oblique view
        • Check for injury to superior gluteal NV bundle
        • Posterior column
        • Check for injury to superior gluteal NV bundle
        • Anterior wall
        • Very rare
        • Anterior column
        • More common in elderly patient with fall from standing
        • Axial CT shows anterior to posterior fx line
        • Only elementary fx to involve both columns
        • Associated patterns
        • Illustration
        • AP
        • Obturator ob.
        • Iliac ob. 
        • CT
        • Comments
        • Associated Both Column
        • Characterized by dissociation of the articular surface from the innominate bone
        • "spur sign" on obturator oblique
        • Transverse + Post. Wall
        • Most common associated fx
        • Associated with the highest incidence of nerve injury
        • T-type
        • May need combined approach
        • Anterior column or wall + Post. hemitransverse
        • Most common in elderly patients
        • Post. column + Post. wall
        • Only associated fracture that does not involve both columns
