Osteoinduction, osteoconduction and osseointegration [PDF]

European Spine Journal, 2001
Osteoinduction is the process by which osteogenesis is induced. It is a phenomenon regularly seen in any type of bone healing process. Osteoinduction implies the recruitment of immature cells and the stimulation of these cells to develop into preosteoblasts.

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

Novel functionalized Ti6Al4V scaffold for preventing infection and promoting rapid osseointegration

Materials & Design, 2023
Total hip arthroplasty (THA) is the most common and radical treatment for end-stage hip disease. Prosthesis loosening and periprosthetic infection are the most serious complications after THA, which may lead to prosthetic dysfunction.
