Well, Im gonna weigh in on this one a bit. FIrst of all, I would like to point out that the stigma attached to osteopathic medicine is much much harsher in premed circles than amongst actual physicians and laypeople. I have shadowed ER docs, family practice physicians, and orthopedic surgeons, and in all of these fields I found the same thing: MDs and DOs practicing together, with equal status. Believe me, the MD vs DO thing is pretty much just a premed issue. The only realistic consideration that you need to make when you choose whether to apply DO or not is: do you want an extremely competitive residency?
DOs do have a very tough time matching into some programs because there few osteopathic programs out there. Keep in mind, I am talking only about VERY competitive residencies, such as derm, neurosurgery, plastic surgery, ENT, etc. Moderately competitive residencies are very realistic for motivated DO students, especially ER and anesthesiology. General surgery also has a fair number of DO spots, so I wouldnt go so far as to say that DO route=impossible to match surgery. Also, keep in mind that DOs have their own residencies and hospitals, so it is not like they are constantly being discriminated against when applying for jobs or residency.
My strategy when I applied this year was this: If I got accepted MD, I would have gone for that, but if not, I would have no problem going DO route (much better than waiting another year for the same thing). I got into MSU College of Osteopathic medicine, and that is where I am going. I have had no problems with stigma so far, besides when I am talking to other premeds who dont know much about DO route. Laypeople do not know, or care about the difference between MD and DO. In fact, I dont even bring it up anymore, I just say I am going to be going to med school at MSU (which is a completely true statement). Hope this helps, good luck.
