Implant-Bone Interface of Sacroiliac Joint Fusion Using iFuse Implant System
Figure 2
The two images show the SI joints at different levels at the same time point. SPECT/CT visualized no tracer uptake along the implant in the left SI joint with no signs of instability of the fused joint (arrows). Along the right SI joint, persisting tracer uptake is visible as a sign of yet incomplete ingrowth.
