Consequently, titanium has been replaced by cobalt-chrome (Co-Cr). However, four cases of Co-Cr modular neck breakage have been reported in the literature. In the present paper, two cases of Co-Cr modular neck fractures are described together with a literature review. The aim of this work is to discuss the risk factors and characteristics of this rare complication. We described two cases of fracture of long varus Co-Cr modular femoral neck connected with cementless press-fit stem. Some risk factors, such as long varus type of modular neck, overweight and/or high demanding physical activity, might have contributed to implant failure.</p>}, number={12-S}, journal={Acta Biomedica Atenei Parmensis}, author={Murena, Luigi and Maritan, Guido and Concina, Chiara and Scamacca, Veronica and Ratti, Chiara and Canton, Gianluca}, year={2019}, month={Dec.}, pages={187–191} }
