Femur Flashcards
Examinations for the FEMUR
AP PROJECTION
LATERAL PROJECTION
Mediolateral
TRANSLATERAL PROJECTION
CROSSTABLE LATERAL
Patient Position for the AP PROJECTION of the femur
PP: Supine
Distal femur (knee included): leg rotated 5o inward ( places limb in true anatomic position)
Proximal femur (hip included): leg
rotated 10-15o inward (places femoral neck in profile)
Patient Position for the LATERAL PROJECTION Mediolateral of the femur
PP: Lateral recumbent; affected side against IR
Distal femur (knee included): unaffected
limb draw forward; pelvis in true lateral
position; affected knee flexed 45o; femoral epicondyles ┴ to IR;
Proximal femur (hip included):
unaffected limb draw posteriorly; pelvis
rolled 10-15o posteriorly
Patient Position for the TRANSLATERAL PROJECTION CROSSTABLE LATERAL of the femur
PP: Dorsal decubitus; IR placed vertically against medial/lateral surface of femur
Reference Point of the AP PROJECTION of the femur
RP: Midfemur
Reference Point of the LATERAL PROJECTION Mediolateral of the femur
RP: Midfemur
Reference Point of the TRANSLATERAL PROJECTION CROSSTABLE LATERAL of the femur
RP: Medial side of midfemur
Centray Ray for the AP PROJECTION of the femur
CR: ┴
Centray Ray for the LATERAL PROJECTION Mediolateral of the femur
CR: ┴
Centray Ray for the TRANSLATERAL PROJECTION CROSSTABLE LATERAL of the femur
CR: Horizontal
SS: Femoral neck & hip joint (10-15o); knee joint (5o)
AP PROJECTION
SS: ¾ of femur & adjacent joints
LATERAL PROJECTION
Mediolateral
SS: Entire femur & knee joint
ER: For patient who can’t tolerate routine lateral position because of fractures or destructive disease
