Figure 2

Histologic H&E sections revealed maintenance of the PMMA/BC microspheres without migration beyond the lamellar injury. Healing of the annular defect occurred with early signs of the formation of new collagen without an inflammatory response. Most of the microspheres were lost during histologic preparation, and blue material observed within the voids is likely proteinaceous fluids or retained collagen from the injected PMMA/BC. There is a minor amount of fibrous tissue smoothing the internal layer of the voids.
