Tribology of total hip arthroplasty prostheses
Although total hip arthroplasty (THA) has provided good results for over forty years, the choice of the optimal bearing surface still remains controversial. Tribology is defined as “the branch of science and technology that deals with the study of friction, wear, and lubrication”.1 Tribology is fundamental to the function and long-term survival of orthopaedic implants. With the development of h...
متن کاملTribology and total hip arthroplasty implants.
Define tribology and discuss its effect on total hip arthroplasty (THA). Tribology is defined as the science of interacting surfaces in relative motion and includes the principles of friction, lubrication, and wear of implant materials. Tribology of the articulating materials in THA is the most important issue for long-term survival of the implants because the fixation of implants either with o...
متن کاملTribology in Total Hip Arthroplasty: Historical Development and Future Trends
Arthritis is a common disease in the elderly population. The most frequent treatment of arthritis is a total joint replacement. Approximatively 1.100.000 hip endoprostheses are implanted per year worldwide. This procedure is very successful in more than 90 % of the patients with good results after up to 10-year follow-ups. Unfortunately, due to the body’s reaction against the wear particles, th...
متن کاملShort-stem prostheses in primary total hip arthroplasty
BACKGROUND Short-stem (SS) prostheses require less resection of the femoral neck, produce a more physiological load pattern in the proximal femur, reduce stress shielding, and aid bone conservation and are, therefore, beneficial for young patients. Conventional cementless implants in total hip arthroplasty (THA) have shown excellent clinical results; however, it is unclear whether SS prostheses...
متن کاملMedium-term Outcomes of Cemented Prostheses and Cementless Modular Prostheses in Revision Total Hip Arthroplasty
There is an increasing trend towards cementless modular femoral prostheses for revision hip replacement surgery, especially in patients with severe proximal femoral bone defects. However, for minor femoral bone defects, the benefit of cementless modular is not clear. We designed a retrospective cross-sectional study to compare outcomes of the two femoral implant designs. There were no significa...
