Hi Chris,
There are actually quite a few Michigan patients within this community.
This post may answer some of your questions, but please search and you'll find more. You can & should also search for Michigan members. But in Sandra's post, you'll find surgeons' names & phone numbers. You can also call the Synthes reimbursement line to get doctors names, 1-800-895-7764.
I also tried the Depuy Spine surgeon locator (for the Charite, Discover, et al), but the surgeon locator utility is not working.
