Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

Advanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

Massive Femoral Osteolysis Secondary to Loosening of a Cemented Roughened Long Stem: A Case Report

Case Reports in Orthopedics, 2014
The surface finish of a femoral stem plays an important role in the longevity of cemented total hip arthroplasty. In efforts to decrease the rate of aseptic loosening, some prostheses have been designed to have a roughened surface that enhances bonding ...

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.
