Abstract:

BACKGROUND: As a noninvasive physical factor, magnetic fields have been investigated for many years, and have been applied in clinic for bone biological field. However, their biological effect, underlying mechanism and model of application need to be studied in depth. 

OBJECTIVE: To review the research progress and trend of magnetic fields in bone biology from four aspects: animal models, cells, mechanism and clinical application.
METHODS: The first author searched the literature in PubMed, WOS, CNKI and WanFang databases from 2012 to 2018. The keywords were “magnetic fields, bone fracture, osteoporosis/osteopenia, bone healing, bone growth, arthritis, osteoblasts, mesenchymal stem cells” in English and Chinese, respectively. Totally 103 articles were firstly acquired and finally 51 eligible articles were selected for analysis.
RESULTS AND CONCLUSION: Magnetic fields can affect the balance between osteoblasts and osteoclasts, regulate bone metabolism and osteogenesis, enhance bone biomechanical properties, as well as accelerate the repair of osteoporosis, non-union fractures, osteoarthritis and soft tissue injuries. The combination of magnetic field and other methods such as materials, drugs, or exercise can improve the curative efficiency. Wnt, RANK, MAPK and other signaling pathways play critical roles in magnetic field-mediated osteogenesis. However, the best conditions for magnetic field to promote osteogenesis and the detailed mechanism require to be further studied. The potential or long-term effects of magnetic field on the human body are not yet fully understood. Importantly, the magnetic field parameters should be carefully chosen in clinical practice.
