Abstract
Introduction: Recent evidence suggests that antibiotics exert direct effects on bone at a cellular level, disrupting mitochondrial function and cell activity. This comprehensive literature review aims to evaluate evidence for the effects of antibiotics and antimicrobials on bone and discuss the clinical implications.
Areas covered: A literature search was conducted on electronic databases covering a period from 1969 to 2010. Studies were included if they reported in vivo and in vitro experimental findings regarding the use of antibiotics and synthetic antibacterials in both animals and humans, focusing on bone cell function and especially fracture repair.
Expert opinion: Current research suggests that these negative results could be due to direct effects of antibiotics on mitochondrial physiology within mammalian cells. Treatment doses of antibiotics, especially those released from topical delivery systems such as bone cements, result in antibiotic concentrations thousands of times higher than those required to inhibit bacterial growth. Our findings suggest a need to develop current antibiotic delivery systems to elute sufficient doses to inhibit bacterial growth without negative effects on bone physiology and fracture repair processes.
