title: 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 total hip arthroplasty. The implant failed because of a filling mismatch between the proximal and distal femur.
