This investigation prospectively studied a consecutive series of 22 proximally cemented, distal cementless, femoral components with a minimum follow-up time of 24 months. The prosthesis was a titanium, proximally cemented, femoral component with a distal press-fit fluted design. Five hips (23%) developed aseptic mechanical loosening at an average of 46.2 months and required revision. The technique required excessive removal of cancellous bone leading to a suboptimal bone-cement interface. The early failure rates of this prosthesis are unacceptably high for a contemporary hip design. To the best of our knowledge, no clinical studies have reported on the stability and longevity of this new proximal cementing technique incorporated with a distal press-fit femoral design.
