Go do the course. Even if you don't like it and don't want to do bunions that way you'll learn something.
I did zero distal osteotomies in residency. I branched out and tried them over the past few years. Some went well, some less so. I thought it would make my life better, but it just made my life different. Then I started doing them MIS. They have their own new issues, but there really is something funny about having post-op visits where there is no incision to manage. It jokingly takes the first 3 weeks of the recovery out of the picture. You start asking yourself questions like why is the patient here and how many visits does someone really need.
