Body was changed:

Pierre Delbet was a French surgeon who operated on neck of femur fractures1. He classified these fractures into four types in adults, which is now known as Delbet's classification of fractures of proximal femur2. This was later adopted by Collona for fractures of the femoral neck in children without changes. This classification helps predict the risk of AVN (avascular necrosis) of the femoral head as well as determine operative vs non-operative management. 

  • Type I: Trans-epiphyseal separation - fracture through proximal femoral physis, and represents Salter Harris-Harris Type I fractures of the proximal femur (<10%). 
    • IA: without dislocation
    • IB: with dislocation 
  • Type II: Transcervical fracture - fracture extending through mid-portion of femoral neck. This is the most common type of paediatric hip fracture (40-50%).
  • Type III: Cervicotrochanteric fracture - fracture though base of femoral neck (25-35%).
  • Type IV: Intertrochanteric fracture between the greater and lesser trochanters (6-15%). This type of fracture has the best outcome.
