Biolox® Delta ceramic has been optimized with nano-sized, yttria-stabilized tetragonal
zirconium and strontium oxide to help limit cracking propagation. Although its mechanical …

In replacement surgery of the hip joint, an implant is replaced into the natural femur which
recreates the articulation and functionally of a natural joint. Total hip replacement is …

Background Positioning of total hip bearings involves tradeoffs, because cup orientations
most favorable in terms of stability are not necessarily ideal in terms of reduction of contact …

Background Lewinnek's recommendation for orienting the cup in THA is criticized because it
involves a static assessment of the safe zone and because it does not consider stem …

Advanced neuroimaging provides new opportunities to enhance head injury models,
including the incorporation of white matter (WM) structural anisotropy. Information from high …

The revision rate of large head metal-on-metal and resurfacing hips are significantly higher
than conventional total hip replacements. The revision of these components has been linked …

Edge loading causes clinical problems for hard‐on‐hard hip replacements, and edge
loading wear scars are present on the majority of retrieved components. We asked the …

Background Large-diameter femoral heads for metal-on-metal THA hold theoretical
advantages of joint stability and low bearing surface wear. However, recent reports have …

Wear is one of the main reasons for failure of modular total hip replacements. Recent
evidence suggests that fretting wear occurs at the taper junction which provides fixation …

Finite element (FE) simulation plays a major role in computing stress and predicting the
failure of biomedical components. Normally in past, researchers focused on developing a …
