Background: Mechanical failure of femoral stems at the modular junction of revision hip
arthroplasty systems has been reported only infrequently. In the current study, the cause of …

Background Total hip arthroplasty (THA) presents as an excellent treatment for the
osteoarthritic hip, demonstrating good survival rates. However, aseptic loosening and …

Evidence supporting modular, tapered stems for severe proximal metaphyseal and
diaphyseal bone loss is limited. We report our clinical experience with its use for severely …

We report on two patients with fracture of a modular, tapered and distally fixed, uncemented
titanium revision hip stem, not previously described. A failure analysis revealed that the …

In recent years, hip prosthesis stem revision by means of modular revision systems has
reached an essential role in revision prosthetics. It is an extremely successful technique …

Aims We evaluated a large database with mechanical failure of a single uncemented
modular femoral component, used in revision hip arthroplasty, as the end point and …

Distally fixed modular implants have seen a recent increase in use, to manage proximal
femoral bone loss often encountered during revision total hip arthroplasty (THA). Forty-three …

The fatigue strength, effects of a notch on the fatigue strength, and fatigue crack growth rate
of Ti-15Zr-4Nb-4Ta alloy were compared with those of other implantable metals. Zr, Nb, and …

Background Fractures of modular revision stems at the taper junction are rare but severe
clinical problems. The purpose of this study was the estimation of taper loading to identify …

Purpose: Modular fluted tapered stems are one of the most commonly used implants in
femoral revision surgery. Due to the relative lack of studies on the Restoration modular fluted …
