In 12 patients with corticalization and hypertrophic pseudarthrosis were present after dynamization, the old nail was removed and nail exchange was performed with a longer and larger diameter nail to pass the region formed in the cortex approximately 2-3cm inferior from the old nail.
Corticalization is cortex-like sclerosis in the distal of the nail and it may indicate the early sign of dynamization treatment failure in hypertrophic nonunion after femoral transverse diaphyseal fractures. When corticalization is seen during follow-up after dynamization is performed because of non-union of a femoral transverse fracture, nail exchange should be performed without further delay. More rigid fixation should be applied with a longer and thicker nail crossing the area of corticalization.
