Abstract:
INTRODUCTION:Lower limbs anatomical and biomechanical parameters are essential in several paediatric orthopaedic disease, which makes their exact measurement necessary. AIM:The aim of the author was to evaluate the reliability of the EOS 2D/3D System, a 3D reconstruction capable imaging device in children. METHOD:3D reconstructions were performed in 523 cases aged between 2 and 16 years in whom no abnormality influencing lower limbs biomechanics was observed. For statistical analysis intraclass correlation, paired-samples t-test, Spearman-correlation and Welch-test were used. RESULTS:Excellent results were found for all parameters in reliability test used by the operator. The step-forward position used during the examination influenced the sagittal tibiofemoral angle only. All examined parameters showed significant correlation with age and gender. Height correlated with neck-shaft angle, hip-knee shift, femoral and tibial torsion only. CONCLUSIONS:The EOS technology proved to be an appropriate method to measure lower limbs anatomical parameters in children. Changes in these parameters during development correlated with age and gender. :Bevezetés: Az alsó végtag anatómiai és biomechanikai paraméterei számos gyermekortopédiai betegség kulcstényezői, így pontos mérésük elengedhetetlen. Célkitűzés: A szerzők célja a rendelkezésükre álló 3D rekonstrukcióra képes képalkotó eszköz, az EOS 2D/3D System gyermekkori alkalmazhatóságának vizsgálata volt. Módszer: A 2–16 éves korcsoportba tartozó 523 egyén 3D modellezését végezték el, akiknél az alsó végtag biomechanikáját befolyásoló eltérés nem igazolódott. Az adatok statisztikai feldolgozásához intraclass korrelációs vizsgálatot, páros t-próbát, Spearman-korrelációt, illetve Welch-tesztet alkalmaztak. Eredmények: A megbízhatósági vizsgálat során az operátor minden paraméter esetében kiváló eredményt ért el. A képalkotás során alkalmazott előrelépett pozíció egyedül a sagittalis tibifemoralis szögnél okozott eltérést. A szerzők által vizsgált összes paraméter összefüggést mutatott a korral és a nemmel. Ezzel szemben a magassággal nem mutatott összefüggést a collodiaphysealis szög, a csípő-térd eltolódás és a femoralis és tibialis torzió. Következtetések: Az EOS-technológia alkalmas módszernek bizonyult az alsó végtag anatómiai paramétereinek mérésére gyermekkorban. Ezek változása összefügg a nemmel és a korral egyaránt.
