Summary
Metal-on-metal hip resurfacing can cause pseudotumours, but this review explains their cause and prevention. Appropriate patient selection and surgeon training can ensure continued safe use of this hip resurfacing method.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Tissue engineering
Background:
- Metal-on-metal hip resurfacing has seen widespread use over the past decade.
- Recent concerns have arisen regarding destructive soft tissue reactions, termed pseudotumours, associated with these implants.
- This has led to significant controversy within the orthopedic community.
Purpose of the Study:
- To elucidate the mechanisms underlying pseudotumour formation after metal-on-metal hip resurfacing.
- To outline strategies for preventing these adverse soft tissue reactions.
- To advocate for the appropriate use of hip resurfacing in selected patient populations.
Main Methods:
- This study is a review of existing literature and clinical data.
- Analysis of reported cases of pseudotumour formation.
- Evaluation of surgical techniques and patient selection criteria.
Main Results:
- Pseudotumours result from adverse reactions to metal debris generated by articulating metal-on-metal surfaces.
- Specific patient factors and surgical technique influence the risk of pseudotumour development.
- Preventive measures focus on optimizing implant positioning and patient selection.
Conclusions:
- Pseudotumours are a known complication of metal-on-metal hip resurfacing, linked to tribocorrosion and ion release.
- Understanding the etiology allows for targeted prevention strategies, including careful patient selection and surgical expertise.
- Metal-on-metal hip resurfacing remains a viable option for specific patients when performed by adequately trained surgeons, minimizing complication risks.
