PEMF Therapy

Latest PEMF Study 2019 for Bone Fractures

Bone Fracture

Mandible fractures are the second most frequent of the facial bone fractures. The common treatment of mandibular fractures has various disadvantages, including obviation of hospitalization, surgical morbidity, relatively high cost, long period of immobilization and delay of rehabilitation. Therefore, a safe and non-invasive way to accelerate the healing of the broken bone has been the topic of numerous studies.

Pulsed electromagnetic fields (PEMF) therapy is a natural and drug-free method of electrical stimulation and has been used for several years to supplement bone fractures. In 1979, PEMF therapy was approved by the FDA for the healing of nonunion fractures. Since then, more and more researchers have turned their focus to PEMF for bone fractures.

In this blog, we will introduce you to a study conducted by researchers at Shahid Beheshti University of Medical Sciences and Bushehr University Of Medical Sciences. The study was published in the Journal of Stomatology, Oral and Maxillofacial Surgery on March 2, 2019. These researchers conducted a randomized trial to see the effect of pulsed electromagnetic field on mandibular fracture treatment.

Method

This research was a randomized control trial study. The sample for this trial consisted of patients with a mandibular fracture who were hospitalized in order to receive closed reduction treatment. The participants were randomly selected and then sequentially divided into two groups. Sixteen participants each in control group and case group.

The 16 patients in the control group received conventional therapy without any extra treatment, while the other 16 patients in the case group received PEMF therapy in addition to conventional therapy.

First, 16 patients in the case group received immediate post-surgery PEMF therapy for 6 hours. Then, they received 3 hours of PEMF treatment for the next 6 days. Finally, the same process was repeated for 1.5 hours from day 8 to day 13 after surgery. The maxillomandibular fixation (MMF) device was removed four weeks after the surgery. However, the other 16 patients in the control group did not receive any additional treatment.

To evaluate the efficiency of PEMF treatment for bone fractures, the researchers need to analyze the data from this clinical trial and radiographical assessment. They employed a direct digital panoramic machine to calculate the computerized density of the bone. Those measurements were used for comparison of the results between the control group and the study patients.

Results

Compared with the control group, the percentage of changes in bone density of the two groups revealed that the case group had insignificant decreases 14 days after the surgery and a significant increase 28 days after the surgery . After releasing the MMF, a bimanual mobility test of the fractured segments showed the stability of the segments in all 32 patients. In the case group, the mouth opening was significantly more stable than that of the control group.

Conclusion

The search has shown that PEMF therapy postoperatively leads to increased bone density, faster recovery, increased formation of new bone, a further opening of the mouth, and decreased pain.

These results are exciting! It provides a new idea for the treatment of Mandible fractures and other bone fractures. Based on the results of this research, we would recommend daily use of a PEMF device to relieve pain and accelerate the repairment of broken bone.
