Abstract: The objective of this study was to evaluate the role of three-phase bone scintigraphy (TBS) as a guide to implant removal in patients with femoral shaft fractures treated with bridging-plate (BP) or interlocking nail (IN), since this decision is based on non-confident criteria. Thirteen patients were studied, six with IN and seven with BP. They were imaged on a camera- computer system after the intravenous injection of 740 MBq of 99mTc-MDP. Implant removal was performed, on the average, 42.2 months after the fracture, in four patients (two with BP and two with IN). Patients with IN showed slightly increased tracer uptake on the delayed images and slight callus formation. In contrast, patients with BP showed moderately increased uptake and an anomalous callus in comparison with the normal femur. The slightly increased uptake of the tracer in patients with IN may be related to the fact that this implant does not allow movement of the bone fragments. In contrast, patients with BP had more bone remodeling in the fracture site, probably due to movement of the bone fragments. This hypothesis was confirmed by CT which showed bony callus similar to the normal femur in the two patients with IN, but not in the two patients with BP implant.
