I broke my collarbone and 6 ribs in a cycling accident 2 years ago on Christmas Eve.

The collarbone took 10 months to heal enough that I could get back on the bike again. After 5 months there was some calcification between the 2 broken bones - enough to be holding it together although a very tenuous hold. My ortho surgeon didn't want to operate and insert plate as she avoids surgery as much as possible - infection, starting again from scratch etc. [The break should have been plated straight after the accident, but that just proves that you do not go to hospital on Christmas Eve and hope for decent medical attention.] The surgeon increased physio and general exercise like walking with light arm weights. I was happy to avoid surgery - I had been so sore for months after the accident that I didn't want to go there again. Within a month the calcification had increased and the physio again increased.

I still have a lump where the bones knitted crookedly, but it will gradually realign itself I am told. But it doesn't worry me day to day.

Give the injury time to heal and unless there is no knitting at all, you will be able to avoid surgery.
