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

Figure 3

Comparison images of bone callus histology between the control and PEMF groups on days 5, 10, 18, and 28 after fracture. SOFG staining shows cartilage as orange and bone as blue. The PEMF group on day 5 showed less fibrous tissue than the control group. Image magnification ×100. Scale bar: 1 mm.
