- Measure the specimen.
- Decalcify, after bisection of visibly affected areas if needed for penetration of the solution.
- Sample from:
- Visibly affected areas
- Proximal surgical bony margin, if present, inked and as a longitudinal section.
The main sign of acute osteomyelitis is the presence of numerous neutrophils in the stroma. It may also have lymphocytes, plasma cells, bone necrosis,' capillary proliferation and fibrosis.
For toe amputations, determine its extent, particularly compared to the bony surgical or articular margin. Start at the margin and scan the bone at at least intermediate magnification until significant inflammation is seen. Preferably make a mark there and measure the distance from the mark to the margin.

Toe with ulcer and osteomyelitis. Osteomyelitis involves the distal phalanx, middle phalanx and proximal phalanx.
