Bone Scintigraphy of Experimental Composite Bone Grafts Revascularized by Microvascular Anastomoses

In these experiments the reliability of bone scintigraphy with 99mTc diphosphonate, to assess anastomotic patency and the viability of revascularized composite fibular grafts, was studied. It was shown that bone scintigraphy is very useful for the diagnosis of anastomotic patency, but only in the first postoperative weeks. Bone scintigraphy gives no information on the viability of bone grafts.
