Safety Issues in the Use of THR Ceramic Heads and Cups
The safety of ceramic bearings are depending not only on the design and characteristics of the ceramic components, but also on the characteristics of the metallic tapers used for their connection to the stem and to the metal back in THRs. The modularity of today’s THRs offer the advantage of selecting the implant size that better suits the patient’s anatomy, but in this selections of the coupling several pitfalls have to be avoided. This paper is aimed to reviews the characteristics of the ceramic-metal interfaces and their influence on the behavior of the components of ceramic bearings.
