[Osteoscintigraphy in the evaluation of a bone transplant in cranioplasty in children]

Scintigraphy of the skeleton with 99mTc-methylene diphosphonate was performed before operation and 3.6 and 12 mos. after allocranioplasty in 15 children aged 3 to 15 with posttraumatic defects of the bones of the cranial vault. Scintigraphic results were compared with x-ray and clinical findings. The interrelationship of the time course of a scintigraphic picture of an affected zone with x-ray findings of graft readjustment at different time after operation was established. In the authors opinion, combined x-ray and scintigraphic investigations of the cranial bones can be used for objective assessment of the morphofunctional state of a graft after allocranioplasty.
