femur

Question 1

• Pt in supine
• Rotate the limb internally to place it in true anatomic position
• Bottom of IR 2 inches below the knee joint
• CR ⊥ to the mid femur and center of the IR
• shows AP projection of the femur, including the knee joint and hip

Answer 1

AP Projection of Distal Femur

Question 2

• Pt in supine
• Place the top of IR at level of the ASIS
• Rotate limb internally 10 to 15 deg to place the femoral neck in profile
• CR ⊥ to the mid femur and center of the IR
• shows AP projection of the femur, including the knee joint and hip

Answer 2

AP Projection of Proximal Femur

Question 3

• draw the pt uppermost limb forward
• Adjust the pelvis in a true lateral position
• Flex the affected about 45 deg
• IR projects approx. 2 inches beyond the knee to be included
• CR⊥ to the mid femur and center of the IR
• shows lateral projection of the femur

Answer 3

LATERAL PROJECTION Mediolateral
Projection of the distal femur

Question 4

• Place the top of IR at level of ASIS
• Draw the upper limb posteriorly
• Adjust the pelvis so that it is rolled
  posteriorly 10 to 15 deg from the lateral position is sufficient
• CR⊥ to the mid femur and center of the IR
• shows lateral projection of the femur

Answer 4

LATERAL PROJECTION Mediolateral
Projection of proximal femur
