Effects of electromagnetic fields treatment on rat critical-sized calvarial defects with a 3D-printed composite scaffold.

This animal and in vitro study evaluated electromagnetic fields (EMF) treatment combined with a 3D-printed PLA/HA scaffold seeded with rat bone marrow mesenchymal stem cells (BMSCs) for cranial defect repair. The authors report that EMF enhanced BMSC proliferation and osteogenic differentiation and was partly…

Fabrication and physicochemical characterization of a novel magnetic nanocomposite scaffold: Electromagnetic field effect on biological properties.

This in vitro study fabricated PCL nanofibrous scaffolds containing cobalt-zinc ferrite nanoparticles and evaluated physicochemical/mechanical properties and cell-related outcomes. The abstract reports improved hydrophilicity, biodegradation, and stress at break with CZF-NP incorporation, and improved L929 cell…

[Effects of 1.8 mT sinusoidal alternating electromagnetic fields of different frequencies on bone biomechanics of young rats].

This randomized animal experiment exposed 32 young female rats to 1.8 mT sinusoidal alternating electromagnetic fields at 10, 25, or 40 Hz for 90 minutes per day. The 10 Hz and 40 Hz groups had higher BMD and improved femur and lumbar vertebra biomechanical properties compared with controls, and micro-CT suggested…

Pulsed electromagnetic field treatment enhances healing callus biomechanical properties in an animal model of osteoporotic fracture

This animal study evaluated whether daily pulsed electromagnetic field (PEMF) treatments improve delayed fracture healing in skeletally mature ovariectomized (OVX) rats. By 6 weeks, PEMF-treated rats showed improved hard callus elastic modulus and radiographic evidence of better callus bridging compared with sham…
