FEMUR

Question 1

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)

RP: Midfemur

CR: ┴

SS: Femoral neck & hip joint (10-15o); knee joint (5o)

Answer 1

AP PROJECTION

Question 2

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

RP: Midfemur

CR: ┴

SS: ¾ of femur & adjacent joints

Answer 2

LATERAL PROJECTION

Mediolateral

Question 3

PP: Dorsal decubitus; IR placed vertically against medial/lateral surface of femur;

RP: Medial side of midfemur

CR: Horizontal

SS: Entire femur & knee joint

ER: For patient who can’t tolerate routine lateral position because of fractures or destructive disease

Answer 3

TRANSLATERAL PROJECTION

CROSSTABLE LATERAL
