What is the acetabulum of the pelvis?
What is the acetabulum of the pelvis?
The acetabulum is the “socket” of the “ball-and-socket” hip joint. In a healthy hip, the ball fits securely inside the socket and rotates easily within the smooth cartilage lining.
Where is your acetabulum bone located?
pelvis
On each side of the pelvis (hip) bone is the acetabulum, or socket, of the ball-and-socket joint. The surface of the acetabulum is the only part of the pelvis replaced in either hip replacement. The labrum is a ring of fibrocartilage that circles the rim of the acetabulum, deepening the socket.
Where does a acetabular fracture occur?
The hip joint is a ball and socket joint. The socket part is lined with smooth cartilage and is called the acetabulum, which is part of the pelvis. When the socket is fractured, it is called an acetabular fracture. Such fractures are far less common than fractures to the ball part of the joint.
What are the columns of the acetabulum?
The anterior column of the acetabulum includes most of the iliac wing, the anterior acetabulum, and the superior pubic ramus. The posterior column begins at the sciatic notch and includes the posterior portion of the acetabulum and the ischium.
Why is it called acetabulum?
History. The word acetabulum literally means “little vinegar cup”. It was the Latin word for a small vessel for serving vinegar.
Is acetabulum part of pelvic girdle?
The ilium forms the upper boundary, while the pubis, near the midline, forms the rest. The acetabulum is, therefore, a feature of the pelvic girdle.
How do you fracture your acetabulum?
Acetabular fractures most commonly occur due to high-energy injuries. These injuries include car and motorcycle accidents and falls from significant heights. Acetabular fractures occur due to weakened bones, too. Some older people with osteoporosis get acetabular fractures after simple falls.
What is the anterior acetabulum?
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.
What 3 bones make up the acetabulum?
As indicated above, the acetabulum is formed from parts of the ilium, ischium, and pubis. The acetabulum is the cup-shaped socket on the lateral aspect of the pelvis, which articulates with the head of the femur to form the hip joint.
What is the function of acetabulum?
The acetabulum is a cup like socket formed by the connection of the three bones that make up our hip. This socket meets with the femoral head of the femur bone to form the hip joint. Together, these two parts of anatomy allow us to walk, run and move freely.
Which bones form the pelvic girdle 6?
Pelvic Girdle Bones and Parts: Coxal, Ilium, Ischium, Pubis and Acetabulum.
