Pulsing electromagnetic fields (PEMFs) in spinal fusion: preliminary clinical results.

Pulsing electromagnetic fields (PEMFs) were used during the postoperative management of 31 patients submitted to lumbosacral posterolateral fusion (PLF). The fusions were stimulated with PEMFs during the first 2 of the 4 months of postoperative immobilization. Consolidation of PLF was obtained in 20 of the 31 patients after 2 months of stimulation, thus, healing time was cut in half. After 4 months, fusion was observed in 30 out of the 31 cases submitted to stimulation (96%).
