Volkmann's canals

Volkmann's canals, also known as perforating canals, are microscopic structures found in compact bone. They are named after the German pathologist Alfred Volkmann, who first described them.

Etymology[edit | edit source]

The term "Volkmann's canals" is derived from the name of Alfred Volkmann, a German pathologist who made significant contributions to the understanding of human anatomy.

Volkmann's canals are small channels in the bone that transmit blood vessels from the bone's surface to the Haversian canals within the bone. They also facilitate the exchange of nutrients and waste materials between the blood and bone cells.

Function[edit | edit source]

The primary function of Volkmann's canals is to provide a pathway for blood vessels, nerves, and lymphatic vessels to reach the osteocytes, or bone cells. This ensures that the bone receives adequate nutrients and oxygen, and that waste products are efficiently removed.

Clinical Significance[edit | edit source]

Changes in the structure or function of Volkmann's canals can have significant clinical implications. For example, blockage of these canals can lead to bone death due to lack of blood supply. This condition is known as osteonecrosis.
