Regarding stem stability, the diameter of the stem should be considered in relation to the intramedullary canal; canal fill ratio (the stem diameter divided by the diameter of the intramedullary canal) should be > 0.85 to obtain a stable construct. WebA straight stem, in combination with a medially directed reaming, would result in a femoral component that overhangs medially, but an offset stem can re-center the femoral component and maintain the desired alignment. We hypothesized that diaphyseal fit plus this reaming technique can control limb coronal alignment and provide fixation. it henry bowers fanart
