Scintigraphy in postoperative follow-up of osteosynthesis of the femur with a bridge plate associated with an intramedullary pin in rabbits
The objective of this work was to monitor the consolidation of the femur after osteosynthesis with a bridge plate associated with the intramedullary pin using scintigraphy. We used seven New Zealand breed male rabbits, at 4 months of age, with a mean weight of 3.5 kg. We performed a three-phase bone...

| description | The objective of this work was to monitor the consolidation of the femur after osteosynthesis with a bridge plate associated with the intramedullary pin using scintigraphy. We used seven New Zealand breed male rabbits, at 4 months of age, with a mean weight of 3.5 kg. We performed a three-phase bone scintigraphy with technetium-labeled methylene diphosphonate (99mTc-MDP) before and after surgery, and 20, 50 and 90 days postoperatively. The activity index (AI) was calculated by dividing the average number of uptake counts in the region of the osteotomy by the average number of counts in the corresponding region in the contralateral limb. Radiography was performed before surgery, after surgery, and 15, 30, 45, 60 and 90 days postoperatively. We found a direct relationship between the activity index and progress of bone scintigraphy in the evaluation sequence over the period of observation. Scintigraphy allows monitoring of bone metabolism and measurement of vascularization and/or bone or tissue perfusion. The images obtained in the blood pool and static phases are the most appropriate for assessing bone metabolism in the context of this study. The bridge plate associated with the intramedullary pin promotes osteosynthesis with sufficient stability to allow bone consolidation. |
