Prothesis cement envelope in femoral component total hips.
Loading tests showed wide stem-thin cement envelope systems in valgus orientation placed with distal plug to be significantly more stable at higher loads. Narrow stem-thick cement envelope systems in varus without plug were unstable within a marginal factor of safety for cyclic loading. Four cement failures occurred within the thin stem-thick cement system on the upper lateral aspect of the prosthesis cement envelope.
