I was surfing the web trying to find info how therapy benefits post op fusion patients for my ins. appeal. Did not find anything exciting. I did come across something that said if you have instrumentation with your spinal fusion that you should check about taking antibiotics before dental work. No one ever mentioned that before. I already taking them before dental work due to two minor heart problems. I take 600mg of Clindamycin an hour before. It usually kills my stomach but have to do it. It is solely to prevent bacteria from attacking your heart. The gums are related to the heart believe it or not. Not sure why you would need with fusion instrumentaion. Very strange.
