TOTAL hip replacementHIP jointARTIFICIAL jointsThe purpose is to analyze the influence of the elastic characteristics of the materials of the tribological pair: acetabular-femoral head on the maximum pressures in the hip joint endoprosthesis. The paper analyzes the impact of elasticity characteristics (...

With the insertion of a shoulder (12) of the inner shell (2) into the outer shell (1), a preliminary centring of a bevelled counter-surface (11) on a cylindrical centring surface (8), into which a slightly projecting plastic ring (9) is embedded, is carried out. Before the shoulder ...
hip replacements per ormed worldwide each year. Wear over time o the plastic components in hip replacement has traditionally been the limitation in the durability o these implants, especially in young patients. Improved weight-bearing sur aces such as ceramic-on-ceramic and metal-on-metal were ...
Conventional total hip replacements (THRs) are composed of a metal femoral head which articulates against a polyethylene (plastic) cup or liner2. The lifespan of these so-called metal on polyethylene (MoP) prostheses may be limited in younger, more active patients. This is because during activi...

Different cup inclination angles and head lateral microseparation were modelled and their effect on the contact mechanics of the modular MoP hip replacement were examined. The results showed that lateral microseparation caused loading of the head on the rim of the cup, which produced substantial ...
used to replace steel devices by incorporating simple design modifications. This report provides a foundation for polymer selection and documents a complete metal-to-plastic conversion of a retractor used in total hip replacement (THR). The case study focuses on both single-use and reusa...
In Europe these concerns have led to calls to ban metal-on-metal hip replacement devices. Writing in March in the journalThe Lancet, British researchers concluded that "metal-on-metal stemmed articulations give poor implant survival compared with other options and should not be implanted." Metal-...
