  1. DETERMINING 'PI' VS. 'AS'
    • -Place dots:
    • 1. Top of femur heads.
    • 2. Superior aspect of iliac crests.
    • 3. Inferior aspect of ischial tuberosities.
    • -Draw Lines:
    • 1. Femur Head Line.
    • 2. Superior Crest Line (#4 on picture).
    • 3. Inferior Ischial Line (#5 on picture).
    • Measure from the Superior Crest Line to the Inferior Ischial Line on both sides.
    • Record findings in the iliac crests in mm.
  2. Misalignment determination:
    • On the side of LL body rotation.
    • Record in iliac fossa.
  3. PI Listing:
    • Increased measurement.
    • Increased obturator size.
    • Increased lumbar curve (hyperlordosis).
    • Shorter LL.
    • Larger measurement on side of body rotation.
  4. AS Listing:
    • Decreased measurement.
    • Decreased obturator size.
    • Decreased lumbar curve (hypolordosis).
    • Longer LL.
    • Shorter measurement on side of body rotation.
  5. DETERMINING 'IN' VS. 'EX'
    • -Place dots:
    • 1. Center of 1st sacral tubercle (#6 on picture).
    • 2. Center of pubic symphysis (#7 on picture).
    • -Draw Lines:
    • 1. Sacral Center Line: with your rolling ruler perpendicular to the FHL, draw a line through the 1st sacral tubercle towards your dot in the pubic symphysis.
    • -Measure:
    • With your rolling ruler perpendicular to the SCL, measure from the SCL to the center of the pubic symphysis.
    • Record findings in the pubic symphysis in mm.
  6. Misalignment Determination:
    • Pubic symphysis deviates to side of IN.
    • On side of LL body rotation.
    • Written in iliac fossa in mm.
  7. EX Listing:
    • Mimics PI.
    • Decreased ilium width.
    • Increased obturator size.
    • Increased lumbar curve (hyperlordosis).
    • Shorter LL.
    • Pubis crosses SCL. (IN is IN).
  8. IN Listing:
    • Mimics AS.
    • Increased ilium width.
    • Decreased obturator size.
    • Decreased lumbar curve (hypolordosis).
    • Longer LL.
    • Pubis does not cross the SCL.
  9. MD, AD, & HEEL LIFTS. O MY!
  10. MEASURED DEFICIENCY (MD) LINE:
    • 1. Align ruler with top of film.
    • 2. Roll ruler to higher femur head.
    • 3. MD Line: draw line above LOWER femur head.
  11. MD MEASUREMENT:
    • Measure distance perpendicular from FHL to MD line.
    • Record findings above lower femur head, in mm.
    • MD: misalignment before adjustment.
  12. RULES FOR CORRECTION:
    • For every 5 mm of AS or IN: the femur head height is lowered by 2 mm.
    • For every 5 mm of PI or EX: the femur head height is raised 2mm.
    • -For every 1mm multiply by 0.4.
  13. ACTUAL DIFFERENCE (AD):
    • Combines measured difference with correction.
    • Signifies anatomical short leg.
    • Signifies need for heel lift.
    • Written above lower femur head in mm.
    • AD = MD +/- correction.
