[Methods to measure blood supply and detect the viability of the osteomyocutaneous flap]

This article presents three kinds of atraumatic methods to detect the viability of revascularized bone grafts by microvascular anastomoses. Fluorescent assay during operation, 99mTc-MDP bone scan and semiconductor probe measurement and periodical pantomogram postoperatively were used. All the results were analysed quantitatively. The authors conclude that it is effective to detect the viability of the grafted bone with the integration of the three methods mentioned above.
