Radiology of the Hip:
- Discussion:
- obtain view w/ 15 deg of internal rotation;
- draw a line at level of, & parallel to, ischial tuberosities and intersecting
the lesser trochanter on each side;
- compare 2 points of intersection & measure difference to determine the
amount of limb shortening;
- draw horizontal at level of proposed neck cut which may be used as a reference
point during surgery;
- draw a horizontal line at the level of the greater trochanter & see where
it intersects on head of femoral component;
- significant leg length descrepancies can partially be adressed w/ changing prosthetic
offset and partially w/
femoral neck cut;
