If you have the choice, I’d go surgery.
I’m not a Doc or in the medical profession, but I did break both collarbones 11 years ago (multiple fractures in each, all at the same time) and they were too busy keeping me alive to consider surgery. Instead they used a ‘figure 8’ elastic brace-thingie (arms go thru the holes, it crosses in the back, tension pulls the shoulders backwards to kinda align them). By the time I was stabalized the broken bone ends got ‘sticky’ and started to heal (takes about a week from what I remember) so the collarbones were left to heal on their own.
I have ‘overlaps’ (which makes ‘bumps’) and one shoulder droops noticeably (makes my neck look like it’s tilting to the other side), but it’s only noticable if one looks. I get some ‘clicks’/etc. now and then when using the arms/shoulders. Nothing painful or the like.
I lift weights normally (but comparatively light compared to average T-Nationers, tho that’s because of my age - 54 - and years of inactivity after the accident, which means a long time to acclimate my old and damaged frame to lifting heavy).
The only problem I’ve noticed is when I started to ramp up my lifting after about 4 months of acclimating, I got an ache where one of the broken spots healed with an overlap. The best explanation I have is that the bone healing point was being stressed (my muscles got in shape faster than the bone healing point) so I backed off for a few weeks then slowly increased the weights/activity.
That was a year ago and no problems since, so I think the bone caught up with the soft tissue strength-wise. I could be wrong with my self-diagnosis, but a lifetime of moderately hard physical jobs has taught me pretty well how to listen to my body and figure out what’s wrong, and it didn’t seem like a muscle/tendon/etc. problem). It also seems logical.
You only have a week or so (if my memory serves me) before your bone ends get ‘sticky’ and start to heal on their own, so don’t take too long to decide. I have no idea if it’s feasible for surgery after the bones start to heal on their own. If you find anything out on this, let me know please.
Good luck, and if you have further questions let me know.
