I Recently Had A Broken Femur And Had Surgery With

I recently had a broken femur and had surgery with a rod placed in it with screws, in which I did a follow up progress x-ray. I was told one of the screws had broken. I asked the doctor if it would be a problem later on, and he said it should not be a problem...however, I am concerned that it could be a problem later on and they might have to do another surgery later. I am 69 year of age and pretty active and I don't want to have a problem now or in the future. Please let me know what I should ask and talk about with my doctor on my next visit
