Introduction: The success of ceramic implants is attributed to the excellent properties of this material associated with superior wear rates and a chemically inert nature which grants it biocompatibility and greater longevity compared with the traditional metal-on-polyethylene bearing surface. However, there have been an increasing number of reports on audible noises that seemed linked to these hard bearing surfaces, leading some to believe the implant material or design was still to blame.
Case report: In this paper is presented the case of an unusual noise which occurred in a 73 year old woman 6 years after THA implant.
Discussion: We hypothesized that the possible cause of this “click” was the impingement of the neck of the stem against the acetabulum ream or as an other possibility some sort of movement.. View More»
