WebExternal (femoral retroversion): Knees pointing in opposite directions. At birth, internal torsion can be as much as 40 ° and still be normal. External torsion can also be prominent at birth and still be normal. Femoral torsion is recognized by laying the child prone on the examining table. The hips are rotated externally and internally. WebSep 30, 2024 · Background: The EOS imaging system is an advanced piece of equipment for full-body imaging, but its reliability and reproducibility should be further verified.
