A Judet pelvis view is a pair of AP oblique X‑ray projections of the acetabulum taken with the patient rotated about 45° to profile the anterior and posterior columns and walls. These two oblique views—one highlighting the anterior column/obturator region and the other the posterior column/iliac wing—help detect and characterise acetabular fractures and guide management and surgical planning.

The iliac oblique view is an oblique pelvic radiograph obtained by rotating the patient about 45° to profile the iliac wing and posterior column of the acetabulum. It separates overlapping pelvic structures to show the posterior acetabular rim and iliac bone, aiding detection of fractures, dislocations, and joint pathology. Used alongside the obturator oblique view for comprehensive acetabular assessment.

The Judet view is also called an oblique pelvic radiograph (Judet oblique view) — specifically the iliac oblique and obturator oblique views. These specialized oblique projections of the pelvis are used to evaluate acetabular fractures and pelvic column injuries by visualizing the iliac and obturator columns separately. They complement standard AP pelvis radiographs and help identify anterior or posterior column involvement.

Standard pelvis X‑ray views include an anteroposterior (AP) pelvis with both hips internally rotated, AP/oblique views of each hip, and dedicated trauma projections: inlet and outlet views for pelvic ring alignment, Judet oblique views (iliac and obturator obliques) for acetabular assessment, and lateral hip projections (frog‑leg or cross‑table/axiolateral) for femoral neck evaluation.

For Judet views, place the patient supine. For the iliac oblique, rotate the patient 45° with the affected side elevated (up) to show the iliac wing and posterior column. For the obturator oblique, rotate 45° with the affected side down to profile the anterior column and obturator foramen. Keep the pelvis centered, legs extended, and the beam perpendicular to the table over the hip.

The adult pelvic girdle on each side is formed by three fused bones: the ilium, ischium and pubis. The ilium is the broad upper blade forming the iliac crest and supporting abdominal organs; the ischium makes the posterior, weight‑bearing part you sit on; the pubis is the anterior portion that meets at the pubic symphysis and helps form the hip socket (acetabulum).
