Standard Radiographs Pelvis
Other Names
- Standard Radiographs Pelvis
- Normal Pelvic Xray
- Pelvis Xray
Introduction
- This page reviews standard xrays of the pelvis
- These are most commonly obtained in trauma, but can be used to answer specific clinical questions
Standard Views
Anterior-Posterior
- Pelvic Rings: carefully tracer the inner cortex of the pelvic ring, two obturator foramina
- Acetabulum
- Sacraol Foramina
- Proximal Femur
- Aligment
- Sacroiliac Joint: symmetrical, joint space ranges from 2-4 mm
- Pubic Symphysis: should be ≤5 mm

Reference lines and angles used to evaluate in DDH[2] -
![The acetabular angle is a plain film measurement used when evaluating developmental dysplasia of the hip (DDH) which is measured between Hilgenreiner's line and a line parallel to the acetabular roof. At birth it should be less than 28 degrees, and should progressively reduce with maturation of the hip.[3]](/w/images/thumb/c/c5/Acetabular_angle_DDH.jpg/120px-Acetabular_angle_DDH.jpg)

![Frontal pelvic xray demonstrates lateral subluxation of the left hip. The acetabulum has a sloping roof and is shallow. Asymmetry of the femoral head, particularly the medial portion of the head with flattening. Associated widening of the femoral metaphysis.[5]](/w/images/thumb/2/2b/DDH_hip_subluxation.jpeg/120px-DDH_hip_subluxation.jpeg)
