Figure 3: Multiple views of a bone model, percutaneous progressive derotator applied with a crossing angle of 50° between epiphyseal and metaphyseal screws. (a) Lateral, frontal and medial views, (b) Axial view with the guidewires left inside the screws, crossing angle is pointed. (c) Sequence of rotational changes during physeal distraction, (d) Upper view comparing, initial and final appearance of the lower-extremity bone model, before and after the simulated percutaneous progressive derotator guided growth. There is a 41° rotational change
