acetabular notch

The acetabular notch is a deep notch in the acetabulum of the hip bone.

An acetabular notch on the ischium (a groove in the hip socket)

It has a small groove, or foeva, connected through the round ligament to the sides of the acetabular notch.

The obturator crest extends from the pubic tubercle to the acetabular notch.

The acetabular notch is narrow or closed and on the femoral head the fovea is absent.

The acetabular branch of the obturator artery supplies the acetabulum through the acetabular notch.

It consists of strong, flattened fibers, which cross the acetabular notch, and convert it into a foramen through which the nutrient vessels enter the joint.

The intracapsular ligament, the ligamentum teres, is attached to a depression in the acetabulum (the acetabular notch) and a depression on the femoral head (the fovea of the head).

At the lower part of the acetabulum is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the acetabulum.

The acetabulum is also home to the acetabular notch, an attachment site for the ligamentum teres, a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the fovea capitis femoris.

The acetabular notch is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apertures, and lodges a mass of fat.

In contrast to the thick and smooth surrounding lunate surface, the pelvis' articulation with the head of the femur, the acetabular fossa is rough and thin, often transparent, and continuous with the acetabular notch below.

It also supplies an articular branch which enters the hip-joint through the acetabular notch, ramifies in the fat at the bottom of the acetabulum and sends a twig along the ligamentum teres to the head of the femur.
