Obturator foramen

Obturator foramen is a large opening created by the ischium and pubis bones of the pelvis. The structure serves as a passageway for nerves and blood vessels.

Anatomy

The obturator foramen is a large aperture situated in the anterior region of the pelvic bone. It is formed by the ischium and pubis bones. The foramen is covered by a membrane, known as the obturator membrane, which leaves a small opening for the passage of the obturator nerve, obturator artery, and obturator vein.

Function

The primary function of the obturator foramen is to provide a passageway for important blood vessels and nerves. The obturator nerve passes through this foramen to innervate the medial thigh. The obturator artery and obturator vein also pass through this foramen, supplying blood to and from the medial thigh.

Clinical significance

In medical practice, the obturator foramen is an important landmark for certain surgical procedures and in the diagnosis of certain conditions. For example, in obturator hernia, a part of the intestine protrudes through the obturator foramen. This condition is rare but can cause serious complications if not treated promptly.
