Osteocyte enhancement function of bisphosphonates in prosthetic replacement
Journal Title: Pakistan Journal of Pharmaceutical Sciences - Year 2015, Vol 28, Issue 3
Abstract
aseptic loosening after prosthetic replacement is the primary cause of shortened service life and lowered stability of prosthesis, and increased revision rate after joint replacement. Factors of causing the loosening of joint prosthesis include mechanical factors and biological factors. The mechanical effect of bisphosphonates (BP) is quite obvious, which can enhance osteocyte function, accelerate the generation of new bone and lower bone resorption activity of osteoclast and macrophage. In animal experiment and adjuvant therapy of patients after joint replacement, BP also shows up the functions of reducing osteolysis induced by wear debris, preventing stress shielding and interface fretting and enhancing bone density. This paper elaborated the mechanism of BP adjusting bone metabolism, and analyzed the action principle and the vital function of it in prosthetic replacement. It has proved that BP can effectively reduce the early peri-prosthesis bone absorption after total hip replacement and improve bone mass peri-prosthesis. It is currently the significant choice of preventing bone lose of peri-prosthesis after operation.
