Polyetheretherketone implants with hierarchical porous structure for boosted osseointegration

Biomaterials Research, 2023
Background Good osseointegration is the key to the long-term stability of bone implants. Thermoplastic polyetheretherketone (PEEK) has been widely used in orthopedics; however, its inherent biological inertia causes fibrous tissue to wrap its surface ...

Extramedullary Osseointegration—A Novel Design of Percutaneous Osseointegration Prosthesis for Amputees

Frontiers in Bioengineering and Biotechnology, 2022
The percutaneous osseointegrated (OI) prostheses have greatly improved the overall quality of life for amputees. However, the long-term maintenance of the OI prostheses is still challenging. A major problem is bone resorption around the bone-implant-skin interface, which might cause implant loosening or osteomyelitis. Another problem is the breakage of

Implantation of heat treatment Ti6al4v alloys in femoral bone of Wistar rats

Journal of Materials Science: Materials in Medicine, 2022
Two heat treatments were carried out at below (Ti6Al4V800) and above (Ti6Al4V1050) the beta-phase transformation temperature (T TRANSUS  = 980 °C), to study the effect of microstructural changes on osseointegration.

Review on Corrosion, Tribocorrosion and Osseointegration of Titanium Alloys as Biomaterials

Corrosion and Materials Degradation, 2023
When introduced into the body, the implant interacts with biological environment and may suffer corrosion. In addition, when this implant is submitted to friction, it may degrade by tribocorrosion due to the simultaneous action of corrosion by the body ...
