A Virtual Method for Establishing Femoral Stem Position in Total Hip Arthroplasty
… joint. Despite the success of these procedures, femoral stem misalignment remains an area that influences THA success. The relationship between the femoral stem geometry and implanted femoral stem size and orientation is underreported due to limitations in the collection of radiographic data used …

An articulated drill and hybrid tracking navigation system for orthopaedic surgery
… acetabular cup positioning and orientation, and femoral stem positioning. However, in robotic orthopaedic surgery with tracking and navigation system, the femoral stem insertion depends on hand-rasping method and confirmation of position by placing tracking marker at the neck shaft of femoral …

The adoption of laser melting technology for the manufacture of functionally graded cobalt chrome alloy femoral stems
… towards the premature loosening of the femoral stem. In order to improve the stress shielding characteristics of metallic femoral stems, stiffness configurations that offer more flexibility should be considered. This research has investigated the potential of more flexible and …

An Investigation on the Corrosion Susceptibilities of Multi-Alloy Total Hip Replacements.
… applications of the titanium alloy for the femoral stem and a cobalt alloy for the femoral head have been established.

Delamination-fretting wear failure evaluation at HAp-Ti-6Al-4V interface of artificial hip implant
… at HAp-Ti-6Al-4V interface of hip implant femoral stem component to formulate maximum wear depth predictive equation as a novel and fast failure prediction tool. Three simple finite element contact configuration models subjected to different mechanical and tribological properties consist of …

Numerical simulation of implant-bone interaction following cementless joint replacement
… with a central peg and a PCA (Howmedica, Inc.) femoral stem. Although many factors influence interfacial tissue development, mechanical loads are assumed to be dominant. In the short term, the relationship between micro-motion and interface tissue response has been shown. However, long term …

Validation of numerical prediction of bone ingrowth into cementless implants
… ingrowth of bone into the porous coating of the femoral stem of a hip implant. A side plate was incorporated to mimic 3-dimensional characteristics. The evaluation was achieved by comparing the predictions of the numerical model with plane X-ray images of seven patients with Zimmer Anatomic …
