Can version of the proximal femur be used for CT planning uncemented femoral stems?

•PFV is highly variable, when using an uncemented, single-wedge, straight femoral stem.•Native version of the proximal femur (NFV) is not a useable guide for planning the achieved version of an uncemented straight-tapered femoral stem (PFV).•Further work should focus on using the internal bony anatomy and the influence of stem design when planning uncemented femoral stems.
