AI Article Synopsis
- The article provides an update on trunnionosis, a complication that impacts about 2% of total hip arthroplasty revisions.
- Thinner and shorter trunnions, along with factors like high offset implants and large heads, may increase the risk of mechanically assisted corrosion.
- Recognizing the specific causes of trunnionosis is difficult due to its complex, multifactorial nature.
Article Abstract
Aims: To present a surgically relevant update of trunnionosis.
Materials And Methods: Systematic review performed April 2017.
Results: Trunnionosis accounts for approximately 2% of the revision total hip arthroplasty (THA) burden. Thinner (reduced flexural rigidity) and shorter trunnions (reduced contact area at the taper junction) may contribute to mechanically assisted corrosion, exacerbated by high offset implants. The contribution of large heads and mixed metallurgy is discussed.
Conclusion: Identifying causative risk factors is challenging due to the multifactorial nature of this problem. Cite this article: 2018;100-B(1 Supple A):44-9.
