A parametric numerical analysis of femoral stem impaction Open
Press-fitted implants are implanted by impaction to ensure adequate seating, but without overloading the components, the surgeon, or the patient. To understand this interrelationship a uniaxial discretised model of the hammer/introducer/im…

A model of uniaxial implant seating by impaction Open
Implants anchored by press-fit are predominantly implanted by impaction. This method allows sufficiently high forces to be generated easily by the surgeon. Suitable impaction should provide adequate implant seating without damaging the pat…

Maximizing the fixation strength of modular components by impaction without tissue damage Open
Objectives Taper junctions between modular hip arthroplasty femoral heads and stems fail by wear or corrosion which can be caused by relative motion at their interface. Increasing the assembly force can reduce relative motion and corrosion…

Corrosion of the Head-Stem Taper Junction—Are We on the Verge of an Epidemic? Open
Background The modular head taper junction has contributed to the success of total hip arthroplasty (THA) greatly. Taper corrosion and wear problems reported for large and extra-large metal-on-metal bearings as well as for bi-modular THA s…

Influence of trabecular bone quality and implantation direction on press‐fit mechanics Open
Achieving primary stability of uncemented press‐fit prostheses in patients with poor quality bone can involve axial implantation forces large enough to cause bone fracture. Radial implantation eliminates intraoperative impaction forces and…
