Objective:
The aim of this study was to investigate the effect of electromagnetic fields (EMFs) at 900 MHz frequencies on bone fracture healing.
Methods:
The study included 30 adult male Wistar albino rats (average weight: 256 g) divided into two equal groups. Transverse fracture was created manually by pressing a finger on the right tibias of all rats and fractures were fixed intramedullary using a K-wire. Rats in Group 1 were exposed to EMF at 900 MHz frequency 30 minutes a day, 5 days a week for 8 weeks. Group 2, the control group, was kept under the same experimental conditions without EMF exposure. Radiological, mechanical and histological examination of tibial fracture healing was performed.
Results:
There was a significant difference between radiological, histological and manual biomechanical scores of the study and control groups (p=0.020, p=0.006 and p=0.032, respectively). All scores were lower in the study group than the control group.
Conclusion:
Results of this study demonstrate that EMF at 900 MHz of frequency emitted from cellular phones has a significantly negative effect on bone fracture healing in a rat tibia model.
