TRABECULAR BONE 1
2
 
  Trichrome stain of undecalcified bone biopsy shows the interconnected pattern of trabecular bone producing a lattice work that allows for structural support and compressive strength. Trabeculae are typically connected from cortex to cortex. Perforations of the connecting trabeculae lead to loss of scaffolds available for formation of new bone. Most of the bone appears normal in this field, but a few small button shaped forms indicate focal bone loss.
