Volkmann's canals, also known asperforating holes or channels, are anatomic arrangements incortical bones that allow blood vessels to enter the bones fromperiosteum. They interconnect theHaversian canals (running insideosteons) with each other and the periosteum. They usually run at obtuse angles to the Haversian canals (which run the length of the bone) and containanastomosing vessels between haversian capillaries. They were named after German physiologistAlfred Volkmann (1800–1878).
The perforating canals, with the blood vessels, provide energy and nourishing elements for osteons.
