As a start I would get your vitamin D-3 levels checked. Get a good, bioavailable multi mineral/magnesium supplement, and check your urine PH 3X/day.
If you're eating the SAD diet (standard american diet) you'll probably find you're on the acidic side of neutral (7). If so, you're loosing minerals from your bones to buffer that acidic PH which makes it hard for you to repair the fracture.
