Strength of the taper junction of modular revision hip stems : the influence of contamination of the taper junction and the joining condition on the relative motion and pull-off force between the stem and neck part of the MRP prosthesis

In revision surgery, modular implant components allow the surgeon to tailor the characteristics of the implant to the bone situation. Relative motion can occur at the tapered modular connection, leading to fretting corrosion and subsequent biological reactions, particularly due to poor assembly and contamination of the tapered connection. The aim of this study was to demonstrate whether incomplete assembly and inadvertent contamination of the modular taper causes a change in junction strength.
