Femoral neck modularity: A bridge too far—Opposes

Femoral neck modularity in total hip arthroplasty has met with variable success over the years. Following the rise and fall of large metal heads, greater attention has been paid to the effects of trunnion corrosion and modular femoral neck failure. Fretting, galvanic corrosion, and mechanically assisted crevice corrosion challenge all modular junctions. Nonetheless, there are substantial clinical benefits with the use of modularity. Proper design is essential. When well implemented, modularity is an important tool that can contribute to successful total hip arthroplasty.
