Ceramic Surface Engineered Metal-on-Metal Hips system for Total Hip Arthroplasty and Resurfacing Hip Arthroplasty

components for the reconstruction of the acetabulum and metal femoral head components for conventional THA and RHA. The ACCIS®metal components are made of a chrome-cobalt-molybdenum alloy, but are different from other metal-on-metal prostheses. The surfaces of the metal components are engineered with the ceramic Titanium-Niobium-Nitride (TiNbN) in order to minimize metal particulate wear, to pr...

Painful Hips In Children

The clinical challenge in paediatric hip pain is to distinguish urgent conditions such as infection of the hip joint from the more common irritable hip. Transient synovitis is one of the most common causes in children over 3 years of age but it has similar early symptoms to septic arthritis. This article offers a guide to assessment, an overview of common causes, and clarity around which childr...

Advanced Work on the Hips

Bonding and structure of ceramic-ceramic interfaces.

Quantum molecular dynamics simulations of α-Al2O3(0001)/3C-SiC(111) interfaces reveal profound effects of thermal annealing for producing strong interfaces consisting solely of cation-anion bonds and their consequence on interfacial structures. A Si-terminated SiC surface and Al2O3 form a stronger interface (Si-interface) with a Si-O bond density of 12.2  nm(-2), whereas the C interface has an ...
