Early Failure of a Nonmodular Titanium Femoral Stem After Primary Hip Arthroplasty

Early Failure of a Nonmodular Titanium Femoral Stem After Primary Hip Arthroplasty

Abstract Fully porous-coated cementless implants have a low failure rate and excellent survivorship in primary and revision surgery. Failure secondary to implant fracture is extremely rare with modern implant designs. We report an early fracture of a fully porous-coated femoral stem after primary to...

Zusammenfassung:Abstract Fully porous-coated cementless implants have a low failure rate and excellent survivorship in primary and revision surgery. Failure secondary to implant fracture is extremely rare with modern implant designs. We report an early fracture of a fully porous-coated femoral stem after primary total hip arthroplasty. The implant failed because of a filling mismatch between the proximal and distal femur.
