- Discussion:
    - occurs after age 10;
    - mechanism: shear or avlusion with angular force;
    - cartilage failure on the tension side;
    - petaphyseal failure on the compression side;
    - w/ type II frxs, there is a division between epiphysis & metaphysis except for a flake of metaphyseal bone is carried w/ epiphysis, 
           (Thurston Holland sign)
    - healing is rapid, and growth is rarely disturbed;
    - note: Type II frx of distal femur and tibia may result in growth deformity
