Brief summary

There are numerous ways to measure limb length discrepancy in the clinical practice, although their reliability and accuracy are not well known. In our prospective diagnostic study we aimed to test the most popular methods and compare their results to EOS 3D reconstructions data.

Interventions

DIAGNOSTIC_TESTEOS

EOS Micro Dose imaging will be done. SterEOS lower limb alignment reconstruction will be performed measuring the lim length.

DIAGNOSTIC_TESTClinical limb length measurements

Clinical measurement of both lower limbs' length, 3 times in 3 different days by 3 observers. * bony markers position (heel contour, patella and medial malleolus) in resupinate and side position also * tape measuring: * Spina iliaca anterior superior - medial malleolus * umbilicus - medial malleolus * greater trochanter - lateral malleolus * in standing, sitting, resupinate and side position
