Conclusions
The objective of the study was to examine the characteristics of bone quality and its microarchitecture in retrieved metal-on-metal HR by a specific quantitative histomorphometry and μCT method. The results showed that the morphometric parameters considered were crucial for a good understanding of the mechanical properties of HR and may be of significant and essential importance in the pathogenesis of HR failure particularly in the development of late fractures. Although there are several good reports on the survival rate of HR at mid-term follow up, the biological changes of the femoral head underlying the implant over time should always be considered. It remains to be seen whether other late failures will occur. HR is still a good indication for young and active patients; nevertheless good bone quality remains the crucial element to support the implant at longer follow-up.
