➢ Tribocorrosion, the degradative process between metallic modular junctions, is more commonly seen with larger prosthetic femoral heads, longer neck lengths, and higher-offset stems.
➢ The use of recalled modular femoral stems should raise suspicion for tribocorrosion in patients with hip pain.
➢ Fretting corrosion is the predominant source of failure at modular junctions.
➢ The literature is unclear regarding the clinical utility of measuring serum levels of cobalt and chromium.
➢ Reconstructive surgical procedures can be difficult as local pseudotumors can lead to destruction of the abductor musculature.
