Histological Analysis of Bone Callus in Delayed Union Model Fracture Healing Stimulated with Pulsed Electromagnetic Fields (PEMF)

Figure 1

PEMF device representation scheme consisting of Helmholtz coil, pulse generator, and user interface. The PEMF waveform used in experiments consisted of a pulsed burst (burst cycle: 50%, duty cycle: 90%, frequency: 50 Hz). The peak magnetic field intensity within the Helmholtz coil was measured to be approximately 1.6 mT. The cage was placed between the Helmholtz coil.
