Medullary new bone fraction (a) and cortical defect fraction (B) as a function of months of healing for the five patients with more than one serial CT scan. Note that progressive improvement in medullary NB formation (incorporation) occurred in all of the five patients (a) and progressive decrease in cortical defect fraction (defect graft incorporation) occurred in four out of the five patients (b).
