Osteointegration of hydroxyapatite-coated collars in cemented massive endoprostheses following revision surgery

open access: yesBone & Joint Open, 2021
Aims: Hydroxyapatite (HA)-coated collars have been shown to reduce aseptic loosening of massive endoprostheses following primary surgery. Limited information exists about their effectiveness in revision surgery.

Stress shielding at the bone-implant interface: influence of surface roughness and of the bone-implant contact ratio [PDF]

open access: yes, 2020
Short and long-term stabilities of cementless implants are strongly determined by the interfacial load transfer between implants and bone tissue. Stress-shielding effects arise from shear stresses due to the difference of material properties between bone and the implant.

Nervous System-Driven Osseointegration

open access: yesInternational Journal of Molecular Sciences, 2022
Implants are essential therapeutic tools for treating bone fractures and joint replacements. Despite the in-depth study of osseointegration for more than fifty years, poor osseointegration caused by aseptic loosening remains one of the leading causes of ...

The limit of tolerable micromotion for implant osseointegration: a systematic review

open access: yesScientific Reports, 2021
Much research effort is being invested into the development of porous biomaterials that enhance implant osseointegration. Large micromotions at the bone-implant interface impair this osseointegration process, resulting in fibrous capsule formation and ...

An in vivo evaluation of bone response to three implant surfaces using a rabbit intramedullary rod model

open access: yesJournal of Orthopaedic Surgery and Research, 2010
Our study was designed to evaluate osseointegration among implants with three surface treatments: plasma-sprayed titanium (P), plasma-sprayed titanium with hydroxyapatite (PHA), and chemical-textured titanium with hydroxyapatite (CHA).

A novel implant surface modification mode of Fe3O4-containing TiO2 nanorods with sinusoidal electromagnetic field for osteoblastogenesis and angiogenesis

open access: yesMaterials Today Bio, 2023
Implants made of Ti and its alloys are widely utilized in orthopaedic surgeries. However, insufficient osseointegration of the implants often causes complications such as aseptic loosening.
