Orthopedic implant failure as a consequence of metal intolerance

Publication

Abstract

Meeting abstract - XXVI SICOT Triennial World Congress, combined with the 46th Brazilian Congress of Orthopedics and Traumatology - CBOT. In medicine, implants are widespread used mainly as orthopedic and dental implants.

Although the majority of implants is well accepted, significant minority of implants is not accepted from unclear reasons. In patients in whom other causes of implant failure were excluded it is therefore appropriate to determine if they tolerate the material from which their implant is made.

For evaluation of metal intolerance the Melisa test was used. Aim of the study: To minimize the risk of implantation failure after orthopedic surgery in patients after not exactly successful implantation therapy with need of reimplantation or in patients with increased risk of implantation failure due to polyvalent allergy.

Material and methods: Nineteen patients were examined. In concordance with Helsinki declaration and after signature of informed consent every examined patient underwent blood sample collection for Melisa test performance.

Results: In this group of patients, intolerance to nickel was the most common (68%). Intolerance to chromium was found in 58% of patients, to iron and gold in 47% of patients, to molybdenum in 37% of patients, to titanium, aluminium and cobalt in 21% of patients.

Few case studies will be presented. Conclusion: On the basis of immunologic examination results more suitable implant material from available materials regarding to individual susceptibility of the patient was selected for reimplantation.
