2025年2月4日 · Anatomically, the acetabulum is formed by the fusion of the three pelvic bones: the ilium, ischium, and pubis. The ilium forms the upper boundary of the acetabulum, the ischium contributes to the posterior wall, and the pubis forms the anterior wall. In addition, the acetabulum is divided into an anterior and posterior column.

It is bounded by a prominent uneven rim, thick and strong on top, which serves as the point of attachment for the acetabular labrum. The acetabular labrum reduces the size of the opening of the acetabulum and deepens the surface of the hip joint.

2016年5月22日 · The acetabulum is the socket of the ball-and-socket hip joint. Although simplicity is suggested in its most basic understanding as a containing device for the femoral head, the acetabulum in reality is a complex and elegantly designed structure; together with the labrum it is responsible for both the high stability of the hip joint and the ...

2020年6月13日 · The acetabulum, which lies in the “concavity of the arch” created by the two columns, transmits load superiorly via this arch. The two columns connect at an angle of about 60° anteroinferior to the sacroiliac joint and just superior to the greater sciatic notch.

The hip joint, or acetabulum, is responsible for many movements including walking, bending and crouching. It is a ball and socket joint, with the femur (top of the leg bone) sitting inside the acetabulum (hip socket).

Acetabulum, located on the lateral surface of the hip bone, is a deep, cup-shaped hemispherical socket. Its orientation is lateral, downward, and forward. It plays a crucial role as is it articulates with the femur’s head to form the hip joint. Within the acetabulum, we can observe two distinct regions: 1) acetabular fossa, and 2) lunate surface.

2022年4月1日 · Adjacent to the columns and extending over the femoral head are the anterior and posterior walls of the acetabulum. The femoral head articulates with the acetabulum. Letournel’s lines are key radiographic identifiers of acetabular anatomy.

2025年1月7日 · The acetabulum (plural: acetabula) is the large cup-shaped cavity on the anterolateral aspect of the pelvis that articulates with the femoral head to form the hip joint. Gross anatomy All three bones of the pelvis (the ilium , ischium , and pubis ) …

2024年7月4日 · acetabulum. The posterior column is characterized by the dense bone at the greater sciatic notch and follows the dotted line distally through the center of the acetabulum, the obturator foramen, and the inferior pubic ramus. The anterior column extends from the iliac crest to the symphysis pubis and includes the entire anterior wall of the ...

2018年8月8日 · The acetabulum is a large cup-shaped hollow cavity for articulation with the head of the femur on the lateral surface of the pelvic bone, where the fusion ilium, pubis, and ischium.
