Discussion & Conclusion

The two major problems regarding the utilization of alumina on alumina bearing surfaces in hip arthroplasty is a higher risk of dislocation of the implant and a higher theoretical risk of breakage of the liner or the head. The introduction of a new ceramic with improved mechanical properties permitting larger head size should minimize these risks. This fact, associated to the low production of debris of the alumina bearing surfaces open new prospective in performing THR and revision surgery on failed THR.
