    on L2)

  • Click highest point on right femur head (have
    computer place dot there)
  • Click on the highest point of the left femur head
    (place dot)
  • Draw line connecting dots femoral head line

  • Click the highest point on right iliac crest
    (have computer place dot there)
  • Click the lowest point on right ischial
    tuberosity (have computer place dot there)
  • Click the highest point on left iliac crest (have
    computer place dot there)
  • Click the lowest point on left ischial
    tuberosity (have computer place dot there)
  • Would like to be able to click and drag the dots
    to adjust their position and/or select the dot
    and use the arrow keys to nudge it into the
    desired position

    the femoral head line.

  • Need to measure distance between the iliac crest
    line and ischial tuberosity line 90 degrees/
    perpendicular to the femoral head line, not from
    point to point, and not true vertical.
  • Complete for left and right side
  • Measurements ( must be mm) need to be displayed
    on screen (if possible just caudal to the femur
    head dots)
  • Do not need to display these vertical measurement
    lines
  • (having the computer automatically compute the
    measurement would be a plus)

  • Place dot on S2 tubercle (or S1if preferred/
    visualized).
  • Place a dot in the center of the pubic symphysis.

  • Draw line perpendicular to the FHL through the S1
    tubercle to be displayed adjacent to the
    symphysis pubis
  • Measure between pubic symphysis dot and resultant
    line (mm) display just caudal to the pubic
    symphysis dot.
  • (having the computer automatically compute the
    measurement would be a plus)

  • Place a dot on the most lateral aspect of the
    right and left sacral wing
  • Lines perpendicular to the femur head line should
    be drawn extending from these dots, as well as
    the S2 dot, to contact the sacral base line
  • The distance between each of these intersections
    on the sacral base line should be measured (left
    to S2, right to S2).
  • Display measurements just medial to the left and
    right sacral dots.

  • Calculate the Measured Deficiency (m.d.)
  • Extend a line horizontally from most superior
    aspect of the higher of the two femur heads to
    overly the lower femur head. This line would be
    best represented by a short line above the lower
    femur head.
  • Measure the true vertical distance from the most
    superior aspect of the lower femur head to the
    line (from the previously placed dot to the
    line).
  • Record the measurement adjacent to the end of the
    horizontal line with the label MD (as pictured)

  • Place a dot on the most lateral aspect of the
    right iliac wing
  • Place a dot on the most medial aspect of the
    posterior superior iliac spine
  • Lines perpendicular to the femur head line should
    be drawn through these dots
  • Measure perpendicular distance between the
    resultant lines
  • Display measurement just medial to the lateral
    dot
  • Repeat for the left side
