Which view is best for acetabulum?
The ‘Judet view’ is a two-part view of the acetabulum, the collimation of the Judet views is departmentally dependent.
What is Dunn view X-ray?
The Dunn view is a radiographic projection of the hip that demonstrates and examines the hip joint, femoral head, acetabulum, and particularly the relationship of the femoral head and acetabulum.
Is the acetabulum anterior or posterior?
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.
How do you describe acetabular fractures?
Acetabular fractures are a type of pelvic fracture, which may also involve the ilium, ischium or pubis depending on fracture configuration.
How do you classify an acetabular fracture?
The Letournel and Judet acetabular classification [4–6] is widely used and accepted for classifying acetabular fractures, communicating with others, selecting surgical approach, and reporting results [7–10, 12]. This classification, based on plain radiographs, is associated with high interobserver (κ = .

What is the location of acetabulum?
hip joint
The acetabulum is the deep, cup-shaped structure that encloses the head of the femur at the hip joint (Fig. 9.4). It is interesting to note that the acetabulum is formed by a combination of all three bones of the pelvis: the ilium, pubis, and ischium.
What is acetabulum in the hip?
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.
What is alpha angle of hip?
The alpha angle was defined by a line between the center of the femoral head and the point where the distance from the center of the femoral head to the peripheral contour of the femoral head exceeds the radius of the femoral head and by a second line in the axis of the femoral neck.
What is the acetabulum of the hip?
Dr Craig Hacking ◉ ◈ and Dr Masaki Bannai et al. 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.
What is an X-ray of the hip?
X-ray is the basic tool for the study of the hip1,2,3. The method of choice to assess the bone marrow, acetabular labrum, cartilage and peri-articular soft tissue, is magnetic resonance imaging (MRI).
What is a bi-bilateral examination of the hip?
bilateral examination allows for better visualization of the hip joints and femoral neck. It is almost exclusively used in the pediatric population to assess for slipped upper femoral epiphysis (SUFE) and Perthes disease.
Where does the anterior rim of the acetabulum begin?
The anterior rim, or border, (orange line) of the acetabulum begins at the superior lateral aspect of the radiological roof (green dot). It descends caudally and medially to meet the superior border of the obturator foramen (dashed line).
