What type of bone is 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 acetabulum and where would you locate it?

Acetabulum: The cup-shaped socket of the hip joint. The acetabulum is a feature of the pelvis. The head (upper end) of the femur (thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint.

Is the acetabulum an articular surface?

The acetabulum has a ‘C’-shaped articular surface (Fig. 6.50), the lunate surface, which is lined by hyaline cartilage. The deeper part of the acetabulum is non-articular and is occupied by the Haversian pad of fat. The head of the femur is mostly covered by articular cartilage (hyaline).

What is the function of the acetabulum?

Lesson Summary 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.

Why is it called acetabulum?

The word acetabulum is formed by the combination of the Latin root [acetum], meaning “vinegar”, and the Latin suffix [-abulum] a diminutive of [abrum], meaning a “cup”, “holder”, or “receptacle”. Thus formed, the word acetabulum means “a small vinegar cup”.

The acetabulum refers to the part of the pelvis that meets the upper end of the thigh bone (the femoral head to form the hip joint. In a healthy hip, these two bones fit together like a ball and cup, in which the ball rotates freely in the cup.

Can you walk with a acetabular fracture?

How serious is a fracture of the acetabulum?

Fractures of the acetabulum portion of the hip can be quite serious due to its location and formation. Most fractures of the acetabulum are due to severe traumatic injuries, such as a car accidents or falls. The head of the femur bone is usually pushed into the acetabulum socket, creating serious damage.
