Strontium-modified porous polyetheretherketone with the triple function of osteogenesis, angiogenesis, and anti-inflammatory for bone grafting
Source abstract
Abstract
Polyetheretherketone (PEEK) is a potential bone repair material because of its stable chemical and good mechanical properties. However, the biological inertness of PEEK limits its clinical application. Sr2+ has multi biological functions, including promoting bone formation and blood vessel regeneration and inhibiting inflammation. In this paper, PEEK was modified with Sr2+ with the purpose to construct PEEK bone graft material with triple functions of osteogenesis, angiogenesis, and anti-inflammatory. The results showed that Sr-modified PEEK could stably release Sr2+ for a long time in the PBS solution, and indeed could promote the proliferation and differentiation of osteoblasts, promote angiogenesis, and inhibit inflammation. Therefore, it is believed that this multifunctional PEEK with Sr2+ should show great promise for clinical applications in bone repair.
