Final answer:
The greater trochanter should be visible laterally, the head of the femur should align with the acetabulum, and the lesser trochanter should not appear exaggerated, indicating the feet were rotated correctly on the proximal femur.
Step-by-step explanation:
When assessing whether the feet were rotated correctly on a proximal femur, there are three important landmarks that should be visible:
The greater trochanter should be visible laterally indicating correct lateral rotation of the femur.
The head of the femur should be aligned properly with the acetabulum showing that it is properly seated within the hip joint.
The lesser trochanter should not be overly prominent; if it appears exaggerated, this may indicate excessive internal rotation of the hip.
When these three landmarks (the greater trochanter, the head of the femur, and the lesser trochanter) are in the correct alignment, it suggests that the femur has been properly rotated. Medical professionals use this information during physical examination or in radiographic analysis to ensure proper leg positioning and diagnose potential issues.
