different methods have been evaluated for manufacturing the porous ti6al4v alloys according todecreasing stress shielding phenomenon and increasing mechanical compatibility between themetallic components and the host tissue. for this purpose, in this work ti6al4v alloy chips werepressed under 400 mpa pressure and then samples were categorized and heated into two groups at1000 and 1150℃ under a ...

Implant-related infection is a difficult problem in orthopaedics as it not only leads to failure internal fixation, but also increases the financial burden and perioperative risk on patients. In past, orthopaedic implants were designed mechanical fixation devices simply maintain biological properties, regulate surrounding microenvironment. More recently, antimicrobial biocoatings have been inco...

Joint replacement is a major orthopaedic procedure used to treat joint osteoarthritis. Aseptic loosening and infection are the two most significant causes of prosthetic implant failure. The ideal implant should be able to promote osteointegration, deter bacterial adhesion and minimize prosthetic infection. Recent developments in material science and cell biology have seen the development of new...

Orthopaedic implant technology is heavily based on the development and use of biomaterials. These are non-living materials (e.g. metals, polymers and ceramics) that are introduced into the human body as constituents of implants that fulfill or replace some important function. Examples would be prosthetic joint replacements and fracture fixation implants. For orthopaedic biomaterials to succeed ...

Implants are widely used for orthopaedic applications such as fixing fractures, repairing non-unions, obtaining a joint arthrodesis, total joint arthroplasty, spinal reconstruction, and soft tissue anchorage. Previously, orthopaedic implants were designed simply as mechanical devices; the biological aspects of the implant were a byproduct of stable internal/external fixation of the device to th...

Metallic orthopaedic implants have been successfully used for decades but they have serious shortcomings related to their osseointegration and the fact that their mechanical properties do not match those of bone. This paper reviews recent advances in the fabrication of novel coatings to improve implant osseointegration and in the development of a new generation of hybrid organic-inorganic impla...

INTRODUCTION: Orthopaedic prostheses implantation is an invasive surgical procedure, with an increased risk for post-operative infections. Since the life span and quality of these implants is improving and more prostheses are implanted every year, the incidence of post-operative infections will increase. Most implants are based on titanium or nickel-chromemolybdenum alloys, while their overall ...

The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009...

10 Statistical shape analysis techniques have shown to be efficient tools to build pop11 ulation specific models of anatomical variability. Their use is commonplace as prior 12 models for segmentation, in which case the instance from the shape model that 13 best fits the image data is sought. In certain cases, however, it is not just the most 14 likely instance that must be searched, but rather...
