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 are Judet views?
(zhū-dā’), view consisting of two oblique radiographic projections centered on the hip in question, tilted 45° medially or laterally from a true anteroposterior direction; useful for fractures or deformities of the acetabulum.
Which radiographic method is useful to diagnose fractures of the acetabulum?
In the current diagnostic procedure, generally, both plain radiographs and 3D-CT scans are used for the diagnosis of acetabular fractures.
What is a radiographic imaging to characterize an acetabular fracture?
The Judet and Letournel system for acetabular fractures is the most widely used classification system in clinical practice. It classifies fracture based on oblique pelvic view on plain radiographs. Additional classification systems include: Orthopedic Trauma Association classification (primarily for research)
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.
What is obturator oblique view?
Obturator oblique view is obtained on a supine patient with the injured side of the pelvis rotated anteriorly at 45°. The x-ray beam is directed vertically toward the affected hip. It is useful to assess the obturator ring, anterior column (iliopectineal line), and posterior wall of the acetabulum.
How does the Judet view the pelvis?
- patient is supine.
- the affected side is rotated roughly 45° anterior, generally aided by a 45° sponge.
- central beam directed vertically toward the affected hip.
- ensure the patient is central on the table and at no risk of over rolling.
Is acetabular fracture a hip fracture?
An acetabular fracture is a break in the socket portion of the “ball-and-socket” hip joint. These hip socket fractures are not common — they occur much less frequently than fractures of the upper femur or femoral head (the “ball” portion of the joint).
Where is acetabular located?
hip joint
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.
How do you get obturator oblique view?
Where is the iliopectineal line?
The iliopectineal line is a curvilinear line running from the sacroiliac joint along the medial border of the iliac wing and the superior border of the superior pubic bone up to the symphysis and delineates the inner margin of the pelvic ring 1-4.
Which radiographic findings are characteristic of an acetabular fracture?
(b) The inner view of the in-nominate bone. The initial radiographic evaluation of an acetabular fracture typically includes an anteroposterior (AP) X-ray of the pelvis obtained in a patient complaining of inguinal (“groin”) or lateral hip pain following injury or as part of a trauma imaging protocol in a multiply injured or obtunded patient.
Why is it important to classify acetabular fractures?
Correct recognition, description, and classification of acetabular fractures is essential for efficient patient triage and treatment. Acetabular fractures may result from high-energy trauma or low-energy trauma in the elderly.
What is the goal of acetabular imaging?
The goal of acetabular imaging is to depict the fracture and provide necessary information to the surgeon, who ultimately determines whether surgical repair is indicated and how it should be performed ( 42 ).
Which CT image shows a transverse fracture extending across the acetabulum?
(a) Lateral 3D surface-rendered CT image shows a transverse fracture extending across the acetabulum (arrows). (b) Medial 3D surface-rendered CT image shows the fracture extending across the quadrilateral plate (arrows).
