DC electrical stimulation does not improve fusion mass bone quality .
Fusion mass bone quality after uninstrumented spinal fusion in older patients
Euro Spine Journal; 2010; 19; 2200-220898 patients, aged 60 or above, with spinal stenosis to undergo posterolateral spinal fusion using fresh frozen allograft were randomized to receive no electrical stimulation or 40 or 100 microA DC stimulation for a period of at least 6 months. The results of the study indicate that at 1-year follow-up, DC electrical stimulation did not improve fusion mass bone quality. It was observed that smokers and women had lower fusion mass bone mineral density (BMD).
