Harrison's groove

Harrison's groove

A Harrison's groove is a horizontal line at the lower margin of the thorax where the diaphragm attaches to the ribs. It appears in rickets because the patients lack the mineralized calcium in their bones necessary to harden them; thus the diaphragm, which is always in tension, pulls the softened bone inward.

It is named for Edward Harrison. [WhoNamedIt|synd|2437] [E. Harrison. Remarks upon the different appearances of the back, breast and ribs in persons affected with spinal diseases. London Medical and Physical Journal, 1820.]
