Osteoporosis and biomaterial osteointegration [PDF]

Biomedicine and Pharmacotherapy, 2004
Biomaterial osteointegration depends not only on the properties of the implanted material but also on the characteristics and regenerative capability of the host bone. For this reason, researchers involved in biomaterial evaluation now place great importance on the various pathologies often present in orthopaedic patients which can negatively affect ...

Titanium alloys for orthopedic applications: A review on the osteointegration induced by physicomechanical stimuli [PDF]

Journal of Materials Research and Technology
Titanium (Ti) alloys have been widely applied clinically due to their good biocompatibility, corrosion resistance and mechanical stability. However, how to improve the weak osteointegration caused by their intrinsic bio-inertness has been a long-standing

Reducing the prosthesis modulus by inclusion of an open space lattice improves osteogenic response in a sheep model of extraarticular defect

Frontiers in Bioengineering and Biotechnology, 2023
Introduction: Stress shielding is a common complication following endoprosthetic reconstruction surgery. The resulting periprosthetic osteopenia often manifests as catastrophic fractures and can significantly limit future treatment options.
