4. The hip joint is synovial joint formed
by the articulation of the rounded head
of the femur and the cup-like
acetabulum of the pelvis.
It forms the primary connection
between the bones of the lower limb
and the axial skeleton of trunk and
pelvis.
8. INTRODUCTION:
The anterio-
posterior(AP)projection is a
general image used as a first
assessment of the pelvic bones
and hip joint
PATIENT POSITION:
Patient supine on the table, arms
at side or across upper chest
Cushion for patients head
Internally rotate foot and leg
15° to 20° (do not attempt to
internally rotate if fracture or
dislocation suspected), sandbags
may be used to maintain this
position.
9. IR SIZE & ORIENTATION:14x17 inches
(landscape)
GRID: Yes
EXPOSURE:70 kVp:20 mAs
FFD / SID:100cm
CENTRAL RAY:
The collimated vertical beam is centred
over the midline midway between the upper
border of the symphysis pubis and ASIS for the
pelvis.

11. INTRODUCTION:
The (AP)pelvis view is part of a
pelvic series examining the illiac
crest,sacrum proximal.
Patient is supine lower limbs are
internaly rotated 15-25 degree
from the hip
PATIENT POSITION:
The patient is positioned as
described for the basic pelvics
and basic bilateral hip projection.
To avoid pelvic rotation the
anterior superior iliac spines must
be equidistant from the tabletop
The affected limb is internally
rotated to bring the neck of femur
parallel to the tabletop,supported
by sandbags if necessary
12. IR SIZE&ORIENTATION: 14x 17
inches( Landscape)
GRID: Yes
FFD/SID:100cm
EXPOSURE:70 kv;20mAs
CENTRAL RAY:
The collimated vertical beam is
centered 2.5cm distally along the
perpendicular bisector of a line joining the
ASIS and the symphysis pubis over the
femoral pubis.
16. This projection is useful
for demonstration of a
non-trauma hip or
developmental dysplasia of
hip(DDH)and congenital
hip dislocation(CHD)
17. PATIENT POSITION:
The knee joint its
flexed 30-40 degree
in a supine
position.while the
hip externally
rotated by 45 degree
so that the image is
taken toward the
middle of line
conecting the upper
symphysis pubis.

ORIENTATION:14X17inches(Landscape)

CENTER RAY:
3 inches below the level of ASIS and
minimum 1 inches symphysis pubis.
20. INTRODUCTION:
Our study shows that cross table
radiography provides acceptable
information for clinical use, but has
limited use for precise analysis of
acetabular cup version.
21. Positioning for the cross
table lateral view. a lower
extremity is internally
rotated by 15°-20° in
supine position and then
the hip an knee joints on
the other side are flexed
to prevent interference in
radiographic projection.
Cassette is positioned on
the side of the hip at
right angle relative to
incidence angle there by
projection toward the
groin region at 35°-45° of
incidence parallel to
longitudinal axis of
femur.

neck
24. INTRODUCTION:
The flash profile radiographic view of the
hip has traditionally been used to measure
acetabular coverage in the setting of
femoroacetabular impigment but some belive
it can also be useful in assessing the
morphology of the femoral head-neck
junction.
25. Patient in orthostatic position.
Affected hip against the
cassette.
Pelvis rotated 65°anteriorly in
relation to the cassete.
The femur of the affected side
should be perpenducular to the
floor.
The patient should not be
leaning and the knee should be
locked on the affected side.
The degree in oblique will vary
from patient to patient.
The foot of unaffected side
should be abducted and/or
perpendicular to the image
receptor.

standing behind the x-ray tube to assess
centering. too much collimation light seen
lateral to affected side will indicate off
centering .
28. INTRODUCTION:
Judet’s views are standard radiographic
projections which are employed in patients
with acetabulum fractures.
This projection may be used to assess the
acetabulum when a fracture is suspected
29. ILIAC OBLIQUE
Patient is supine,the
unaffected side is rotated
roughly
45°anterior,generally
aided with a 45° sponge.it
is advisable the patient is
central on the table and at
no risk of over rolling.
OBTURATOR OBLIQUE
Patient is supine,the
a affected side is rotated
rougly 45°
anterior,generally aided
with a 45°sponge.ensure
the patient is central on
the table and at on risk of
over rolling.
