ANTERO-POSTERIOR –PELVIS (basic projection) AND BOTH HIPS (basic projection) FOR RADIOLOGY STUDENTS

1.  ANTERO-POSTERIOR –PELVIS (basic
projection) AND BOTH HIPS (basic
projection)

2.  Antero-posterior –pelvis (basic projection)
and both hips (basic projection)

3. Position of patient and cassette
The patient lies supine and symmetrical on the X-ray
table, with the median sagittal plane perpendicular
to the tabletop.
The midline of the patient must coincide with the
centered primary beam and table Bucky
mechanism.
If the patient remains on a trolley, ideally they should
be positioned down the midline and adjusted to
achieve an optimum projection dependent on their
degree of mobility.

4. To avoid pelvic rotation, the anterior superior iliac
spines must be equidistant from the tabletop.
A non-opaque pad placed under a buttock can be used
to make the pelvis level.
The coronal plane should now be parallel to the
tabletop
The limbs are slightly abducted and internally rotated
to bring the femoral necks parallel to the cassette.
Sandbags and pads are placed against the ankle region
to help maintain this position.
