Leg Length Discrepancy Test

It is diagnosed through physical examinations, measurements of leg lengths from hip to ankle, and imaging tests like X-rays or MRIs to confirm the extent of the discrepancy.

Radiographic measurements are generally considered the most precise method to assess leg length discrepancies accurately.

The best imaging modality for accurately assessing leg length discrepancy (LLD) is full-length standing anteroposterior radiography, also known as a scanogram or orthoroentgenogram. Compared to other imaging modalities like CT or MRI, scanograms provide the necessary full-length visualization of the lower limbs while minimizing radiation exposure and cost.
