Five radiographs show the range of deformity and cortical thickness in lower extremity long bones with decreasing clinical severity. i) Anteroposterior view of femur in severe type III (OIC B) patient showing extreme diaphyseal and cortical thinness with marked deformity and ii – v) type III (OIT A) patients with ii) lateral tibia with marked cortical thinness; iii) and iv) lateral tibia radiographs with improved cortical thickness; and v) lateral femur with marked deformity but reasonably good cortical thickness.
