Sue, Seven gave you a pretty decent description of Osteophytosis. The anterior is just an adjective pertaining to location. Anterior means front, where posterior (like we sometimes refer to our rear ends) means back.
I'm a little confused as to why, with multiple osteophytes and non-responsive tendonitis, he'd tell you that you no longer need follow up with him. This seems to me to be a part of AS, after all, gradually enlarging osteophytes is what leads to the fusion that we are all hoping to avoid. I'd think that these osteophytes in someone your age would be considered to be far more than "normal wear and tear" and if I were you, I'd be looking for a second opinion.
Something to look into further for your possible Reymaud's is sympathectomies. This provedure is usually done by a Pain Mgmt Specialist and the purpose is to "numb" the sympathetic nerves into relaxation thereby increasing the circulation into the affected limb. My Mom has very poopr circulation to her legs and has a sympathectomy to each side of her lumbar side every Fall. The improvement is near to miraculous. Our PM DOc has told us that he gives his cell # out to his Reynaud's patients so that they can call him directly in the event that they have a crises and need to be seem immediately.
I hope you get some answers and relief soon.
