Laboudie P, El Masri F, Kerboull L, et al. - A prospective matched paired study was conducted to compare the in vivo migration patterns applying Ein Bild Roentgen Analyze femoral component of shortened vs standard-length stems cemented line-to-line in primary total hip arthroplasty (THA) at 2-year follow-up. The first 50 consecutive primary cemented THAs were prospectively included in 50 patients applying a 12% shortened stem (AmisK group) of which design was derived from the original Charnley-Kerboull femoral components. This research exhibited that a shortened highly polished double-tapered stem cemented line-to-line provided similar outcomes including minimal subsidence as its standard-length counterpart, with a significantly less distal femoral cortical thickening. Nevertheless, longer-term survival analysis still requires to be ascertained.
