[edit] Discussion of Slipped capital femoral epiphysis

  • Slipped capital femoral epiphysis (SCFE) is a Salter-Harris type 1 fracture through the proximal femoral physis.
  • Unlike typical Salter-Harris type I fractures, SCFE has a high propensity for morbidity.
  • Stress around the hip causes a shear force to be applied at the growth plate.
  • The almost exclusive incidence of SCFE during the adolescent growth spurt indicates a hormonal role.
  • Obesity is another key predisposing factor in the development of SCFE.
  • Stress on the hip causes the epiphysis to move posteriorly and medially.
  • Because the physis has yet to close, the blood supply to the epiphysis still should be derived from the femoral neck; however, this late in childhood, the supply is tenuous and frequently lost after the fracture occurs.
  • Manipulation of the fracture frequently results in and chondrolysis because of the tenuous nature of the blood supply.
  • Clinical presentation often is misleading, with only 50% of patients presenting with hip pain and 25% presenting with knee pain.

[edit] Imaging Findings

  • Salter-Harris type 1 fracture of the proximal femoral physis with posterior-medial displacement of the proximal femoral epiphysis.
