What is the anterior acetabular column?
What is the anterior acetabular column?
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.
Where is the anterior acetabulum?
The os acetabuli, the epiphysis of the pubis, forms the anterior wall of the acetabulum; the acetabular epiphysis, the epiphysis of the ilium, forms a major part of the superior wall of the acetabulum; and a third small epiphysis in the ischium is also formed.
Where is the acetabular located?
The socket is formed by the acetabulum, which is part of the pelvis. The ball is the femoral head, which is the upper end of the femur (thighbone). The acetabulum is the “socket” of the “ball-and-socket” hip joint.
What is a both column acetabular fracture?
Abstract. Purpose of the study: Both column fractures, defined as an acetabular fracture with no articular fragment in connection with the axial skeleton account for approximately 20% of all acetabular fractures. The typical type of a both column acetabular fracture is the C1.
What is sciatic buttress?
The sciatic buttress is the confluence of the anterior and posterior columns of the acetabulum. Together, the columns form a lowercase lambda (λ) shape, with a longer anterior column and a shorter posterior column (Fig 2) (5,14,15).
What is the acetabulum of the hip bone?
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. The margin of the acetabulum is deficient inferiorly. An additional fibrocartilaginous margin of the acetabulum is referred to as the acetabular labrum.
What is one of the functions of the transverse acetabular ligament?
Function. The transverse acetabular ligament prevents inferior displacement of head of femur.
Which ligament secures the femur into the acetabulum?
Ligament of head of femur
In human anatomy, the ligament of the head of the femur (round ligament of the femur, ligamentum teres femoris, or the foveal ligament) is a ligament located in the hip….

What is OS Acetabuli?
Acetabular rim fractures, or os acetabuli, are an intra-articular condition characterized by formation and separation of an osseous fragment originating from the anterolateral acetabular rim.
