Electromagnetic stimulation as coadjuvant in the healing of diaphyseal femoral fractures: a randomized controlled trial.

Introduction: There is controversy in medical literature regarding the use of electromagnetic fields to promote bone healing.

Methods: After designing and building devices capable of generating an electromagnetic field for this study, their safety was confirmed and the electromagnetic therapy was randomly allocated and compared to placebo in patients with fracture of the femoral diaphysis. Treatment began six weeks after the fracture and it was administered once a day, during 1 h, for eight consecutive weeks.

Computational 3D model of in-vitro cell stimulated by electric and magnetic fields.

This work presents the development of 3D computational models that represent two studies about in-vitro cellular experimentation of cell stimulated by magnetic and electric field. The development considered the construction of the stimulation devices, the cell seeding, and the creation of the 3D computational models representing the arrangements. The models and their electromagnetic analysis were done in the ANSYS program.

Magnetic stimulation for fracture consolidation--clinical study.

This paper presents a randomized clinical design for evaluating magnetic fields in the consolidation of femoral shaft fractures. The study involved the design and construction of 20 devices (stimulators and placebos) and the development of 3D computer models of stimulated patient's thighs. A total of 64 patients were included in the study.

Computation electrical variables induced by magnetic stimulation in 3D thigh model.

This paper presents the changes in the electrical variables induced in a 3D thigh model with femoral diaphyseal fracture when it is magnetically stimulated. Three cases with particular geometries of the models were considered: skin, muscle, cortical bone (CB), bone marrow, metal pin, and fracture shape. Fracture shape included electric properties for blood, cartilage, trabecular bone (TB), and cortical bone (CB), to represent the consolidation process.
