Broke my right collarbone (and a host of other injuries) in a high speed motorcycle accident, had a plate and screws inserted as it was a complete break in the middle and ends overlapping by about 2 inches which made leaving it to heal naturally not an option. Plate was literally a pain as when the bone reknitted, the screws holding it in place protruded out the other side of the bone by about 1/2 inch causing tearing and brusing to the tissue around it. Once I got the all clear from the osteo surgeon about 6 months later, got the thing and troublesome screws taken out.
Only real issue is that you're recovering from 2 surgeries as opposed to 1, in my case 3 as midway through the healing process I happened to drop a large metal toolbox on my collarbone snapping the thing again and putting a 45 degree bend in the plate requiring replacement.
Your osteo surgeon will advise based on how well the bone has healed whether its advised to remove the plate, if you can why wouldn't you.
