Fig. 3.

Representative three-dimensional reconstructed micro-CT scans from a sheep of the main study group revealing ectopic bone growth on the posterior side of the femur. (A) Sagittal plane showing the posterior ectopic bone with a trabecular-like structure. The anterior cortical wall demonstrated no obvious signs of a bone response. (B) Transverse plane similarly revealing that the ectopic bone has a trabecular-like structure with a cortical shell. Note the smooth periosteal response on the lateral side as well as the bone loss adjacent to the Si beads.
