I fell this year mid-August. I fractured my right clavicle in two places and 8 ribs as well. The clavicle was displaced about an inch and there were also some bone fragment in there. I spoke with 3 orthopedic doctors and none of them recommended surgery. Apparently the clavicle is not that important of a bone, one of them said it's kind of like your appendix, you don't need it. They all said it is a very dangerous surgery and they rarely operate on them in the case of open wounds and problems with the nerve bundle that runs under the clavicle.
My ribs are about 99% now but still have a little pain in the clavicle. I'm not a dr but have been a nuclear medicine tech for over a decade now. I decided to do a bone scan on myself as they are much more sensitive at picking up bone problems. I did a bone scan at 2 weeks post and there was no metabolic activity in the clavicle (that means no active healing) but the one I just did at 7 weeks shows active healing. You could ask your doctor if he could refer you to a bone scan if you want to check. They usually just stick with xrays but bone scans are much more sensitive.
Matter of fact, the original xray only picked up one rib fracture. We found the rest on the bone scans. I will try to post the images so you can see when I get home later.
I would recommend increasing your calcium uptake, but in the end, if you wait long enough the clavicle will heal 99 times out of 100.
