Traumatic dislocation of epiphysial plate of femur occurs -a) Mediallyb) Laterallyc) Posteriorlyd) Rotationallye) Anteriorly
Traumatic separation of distal femoral Epiphysis 

Overall this injury is rare; However, of all the injuries of epiphysis, injuries of the distal femoral epiphysis have the highest incidence of post-traumatic growth arrest.
These injuries are described according to the direction of displacement of the epiphysis and the corresponding Salter-Harris classification.


Most common is medial or lateral displacement with a fracture of the adjacent metaphysic (a Salter-Harris type II injury). Such injuries reflect a marked valgus or varus stress.
Posterior displacement of the femoral epiphysis is uncommon but can occur as a result of a direct blow to the flexed knee.

Separation of proximal femoral epiphysis (SCFE) occurs postero-medially.
