The acetabulum (/ ˌ æ s ɪ ˈ t æ b j ə l ə m /; [1] pl.: acetabula), also called the cotyloid cavity, is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint. [2] [3]

3 days ago · The acetabulum is a large socket on the lateral face of the hip bone that articulates with the head of the femur to form the hip joint. Anatomically, the acetabulum is formed by the fusion of the three pelvic bones: the ilium, ischium, and pubis.

Oct 8, 2021 · What is an acetabular fracture? An acetabular fracture is a break in your hip socket. Your hip is a “ball-and-socket” joint. Your acetabulum, which is part of your pelvis, forms the socket. Your femoral head, which is the upper end of your femur (thigh bone), forms the ball.

Jan 7, 2025 · 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. All three bones of the pelvis (the ilium, ischium, and pubis) together form the acetabulum.

Oct 6, 2017 · Fractures of the acetabulum are challenging orthopedic injuries to repair, at times leaving multiple small fragments of fractured bone and cartilage. Compounded by the location in a region challenging in which to work and fraught with risk, these "puzzle pieces" must be brought back together to restore hip function and mobility.

Acetabulum fractures are pelvis fractures that involve the articular surface of the hip joint and may involve one or two columns, one or two walls, or the roof within the pelvis.

An acetabular fracture occurs when a force drives the head of the femur against the acetabulum. This force can be transmitted: From the knee (such as hitting the knee against the dashboard in a head-on car collision) From the side (such as falling off a ladder directly onto the hip).

May 22, 2016 · 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 ...

We describe a method to quantify, average, and apply data gathered from normal human specimens to create a standard representation of the ilium and ischium. One hundred healthy hemipelves from 50 human skeletons were evaluated. We measured angles and distances between major anatomic landmarks in the pelvis.

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 ...
