Yea of course, if you're doing procedures and/or surgery.
Could you really not figure this out on your own?
Would you want your surgeon to be clumsy? "Whoops, just accidentally cut the abdominal aorta!! Dang I'm so clumsy." Or the ER doc stitching up the gash on your forehead?
Obviously you're going to be practicing and learning techniques so at some point you'll have it down, but it depends on how "clumsy" you are--e.g., if you have trouble holding a pencil there's not a lot of hope for you.
I'm guessing you are pretty bad since you specifically made a thread about this.
However, there are plenty of specialties where it won't matter. Psychiatry, diagnostic radiology, and a lot of others. Again, it's dependent on what exactly you mean by clumsy.
