X-RAY OF HIP JOINT
X-ray Hip Joint A/P View
Hip Joint AP (Bilateral Hip)
Region: hip joint, acetabulum, femoral head, femoral neck
Pathology: fracture, arthritis and dislocation of femoral neck
SID: 100 cm (40 inches)
Central Ray: perpendicular beam directed at the point 2.5 cm (1 inches) superior to the pubic symphysis
Respiration: suspended
Position:
1. The patient is placed in a supine
position.
2. Place the spot of 2.5 cm above pubic
symphysis at the center of image receptor (IR).
3. Place the arm outside the clinical intent and place gonadal shielding within
the extent of not interfering with the radiographic examination.
4. Immobilize pelvis in
true antero-posterior projection image to prevent rotation and synchronize the
distance between the bilateral anterior
superior Iliac Spines (ASIS)
5. Invert both feet 15°.
Collimation: Include proximal portion of femur and hip joint.
Evaluation:
1. Bilateral ischial
spines and obturator
foramen should be shown symmetrically.
2. Femoral
neck and greater
trochanter should be shown symmetrically.
3. Lesser
trochanter must not be seen.

Hip Joint Lateral (Unilateral Hip, Cleaves)
Region: hip joint, acetabulum, femoral head, femoral neck
Pathology: fracture, arthritis and dislocation of femoral neck
SID: 100 cm (40 inches)
Central Ray: perpendicular beam directed at the femoral neck
Respiration: suspended
Position:
1. The patient is placed in a supine
position.
2. Place femoral
neck at the center of the image receptor (IR).
3. Maintain the filming femur in abduction of 45°.
Collimation: Include 1/3 proximal portion of femur, hip joint and pelvic bone.
Evaluation:
1. The greater
trochanter must overlap with the femoral
head.
2. The lesser
trochanter should be observed below the greater trochanter.
