Non union of bone
He performed limb lengthening surgery every day 1mm increased in tibia bone now for 3 months he increased overall 5cm. Now he is worried that callus is not there in his xray (attached which is taken after exactly after increasing 5cm) and they had given bone marrow transplant as well but not gave any result. Now what are the options does he have bone grafting and what is the success rate or in the cray callus is forming? Please suggest
