I had a herniated disc that they said needed operated on in high school. Saw a chiropractor, avoided surgery....got back to wrestling and lifting with the help of his advice and recommendations. So yes, I say see a chiropractor. Healed fractures can still be checked out by them as it can effect the overall bio-mechanics of your spine.
On another note you may check out this guys stuff. Its about making exercise easier on the joints and support structures to avoid injuries in strength training.....
