Obturator artery

from Wikipedia, the free encyclopedia
Schematic representation of the arteries of the thigh

The obturator artery ("hip-hole artery ") is an artery of the lower extremity. It arises from the internal iliac artery and runs through the obturator foramen or the obturator canal - together with the vein of the same name and the obturator nerve - to the inside of the thigh . It then divides behind the pectineus muscle into an anterior and posterior branch ( ramus anterior and posterior, respectively ). They supply the adductors of the thigh and, via the ligamentum capitis femoris, also the hip joint head of the thigh bone ( arteria capitis femoris ). The ramus anterior anastomoses with the arteria circumflexa femoris medialis , the ramus posterior with the arteria glutaea inferior .

Clinically, the obturator artery is of particular importance because of its proximity to the acetabulum . Especially in the use of hip endoprostheses they can be easily injured and lead to stronger bleeding.
