Abstract:
Objective:To study the effects of pulse electro-magnetic fields (PEMFs) on the healing of tibial condylar osteochondral in rabbits.Methods:Sixteen rabbits were divided into two groups,and osteochondral fractures of left tibia condyle were created,internal fixation was performed with steel wire.Group 1 was constantly treated with PEMFs six hours per day;group 2 was not treated.The results were studied by gross morphology,light microscopy and elect ro-microscopy.Results:75% and 13% fractures were repaired by hyalin-like cartilage in group 1 and in group 2 respectively.Conclusion:PEMFs are essential to facilitation of the cartilage repair.
