Limb length

MAP the LLD

A step-by-step radiographic method for identifying and calculating total limb-length discrepancy.

Practical method

Draw a pelvic reference line between points placed at the inferior margins of both sacroiliac joints.
Identify the limb that appears shorter on this radiograph: a ball imagined on the pelvic line would roll toward that side.
Mark both femoral-head centers, then project equal vertical lines from the pelvic line to a shared horizontal grid line.
Measure both lines. Assign the longer measurement to T_Short as a positive value and the shorter measurement to T_Long as a negative value.
Add any block or lift height: positive beneath the apparent short limb and negative beneath the apparent long limb.

Calculation

Total LLD = T_Short + T_Long + block height

Example: +20 cm + (-16 cm) + 0 cm = +4 cm. The positive result means the limb labelled T_Short is 4 cm shorter.
