A new study has reported an increased risk of spine fractures for women with knee osteoarthritis. Researchers think this may be because of an overall weakness of bone in people with osteoarthritis. This effect of osteoarthritis is also present in the spine, but it is "latent," meaning it occurs much later.

Your doctor is wise to take a baseline measure of your spine for future use. This can help plan treatment for your osteoarthritis and prevent future problems.
