I think I had something similar done to my left clavicle. I don’t remember the exact name of the surgery, but they certainly used suture.
The fracture was right at the end of the clavicle and not healing.
They didn’t mention drilling a hole, which isn’t to say they didn’t.
My shoulder healed well but I had to wear a sling night and day for six weeks, arm strapped to me, with strict instructions to not remove it. Wasn’t as stinky as you might expect.
There is a fairly large vertical scar so not keyhole in my case.
Now I come to think of it (was over 20years ago) the consultant mentioned something about fishing rod eyes, no clue. I assumed they kind of bound it together, but the drilling a hole thing makes more sense.
