Scintigraphy of human autologous rib transplants to a partially resected mandible

The 99Tcm-DP accumulation in split ribs grafted to six cases of partially resected mandibles was examined by scintigraphy at different time intervals after operations and found to be higher than in normal facial bones. The accumulation was highest around one month after the grafting procedure, and later decreasing. Differences between bone chips, split ribs and unsplit ribs are described. Bone scintigraphy is assumed to be of value in following the metabolic state of bone grafts.
