Comprehensive Analysis of a Recalled Modular Total Hip System and Recommendations for Management

Conclusions:
Early failures of modular total hip arthroplasty occur due to fretting and corrosion at the neck-stem junction, resulting in ALTR. Surveillance utilizing metal ion levels and MRI may be indicated for all patients regardless of symptoms, as the early survivorship is poor and the ultimate failure rate may be catastrophically high.

Level of Evidence:
Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.
