BACKGROUND: Conventional embalming relies on arterial cannulation, which may be difficult when vessels are diseased, inaccessible, or damaged. Intraosseous (IO) vascular access, widely used in emergency medicine, provides a rapid and reliable route into the medullary venous system. This technical note describes a simple IO embalming protocol and assesses its feasibility and performance in human cadavers.
MATERIALS AND METHODS: IO access was established in cadavers using bone-marrow needles inserted into the proximal tibia, distal femur, sternum and iliac crest. Standard formaldehyde-based embalming solution was infused using a low-pressure pump. Outcomes were assessed qualitatively by evaluating perfusion patterns, fixation quality, tissue handling, and presence of leakage.
RESULTS: IO access was quick and dependable, requiring no arterial dissection. The proximal tibia provided the easiest insertion, while the iliac crest allowed the broadest diffusion, particularly toward thoraco-abdominal regions. All specimens demonstrated adequate firmness, coloration, and structural preservation suitable for anatomical education.
CONCLUSIONS: IO injection is a practical and minimally invasive alternative to arterial cannulation for cadaver embalming. It reduces procedural complexity, limits exposure to biological fluids, and provides adequate fixation for teaching and research.
