Technetium-99m Methylene Diphosphonate (Tc-99m MDP) has often been used to assess revascularisation of bone, because positive uptake of Tc-99m MDP reflects patent anastomoses and viability of the grafted bone. However, the sequential evaluation of bone scintigraphy has seldom been reported, especially in clinical cases. We carried out sequential evaluation in 17 patients with revascularised bone grafts. In this series, intense or maximal uptake in the grafted bone was observed in the early days after surgery (1-2 weeks postoperatively), with considerable reduction after 4 weeks. Furthermore, it was found that there was no uptake of Tc-99m MDP when the anastomosed vessels were occluded, even after 6 weeks, and these three cases all developed fracture or sequestrum. We therefore believe that bone scintigraphy is reliable in the postoperative monitoring of revascularised bone for at least 4 or 6 weeks postoperatively.
锝-99m亚甲基二膦酸盐（Tc-99m MDP）常被用于评估骨的血管重建，因为Tc-99m MDP的阳性摄取反映了移植骨吻合口通畅及存活情况。然而，骨闪烁显像的连续评估鲜有报道，尤其是在临床病例中。我们对17例血管重建骨移植患者进行了连续评估。在该系列中，术后早期（术后1-2周）在移植骨中观察到强烈或最大摄取，4周后摄取显著减少。此外，发现吻合血管闭塞时，即使在6周后Tc-99m MDP也无摄取，且这3例均发生骨折或死骨形成。因此，我们认为骨闪烁显像在术后至少4或6周对血管重建骨的监测中是可靠的。
