The classification system used most commonly for pediatric hip fractures is that of Colonna. In this classification, the fracture prognosis is dependent on the location of the injury and its interference with the blood flow to the femoral head.

  • Type I: Transepiphyseal fractures, account for 8% of pediatric hip fractures, AVN rate approaches 100%

  • Type II: Transcervical fractures, account for 45% of pediatric hip fractures, 80% are displaced, AVN rate approaches 80%

  • Type III: Cervicotrochanteric fractures, account for 30% of pediatric hip fractures, AVN rate of 20-30%

  • Type IV: Intertrochanteric fractures, account for 10-15% of pediatric hip fractures, fewer complications than types I-III
