Did Ortho Kinematic Imaging For Spine. Preparing For A Spinal Fusion. Have Arthritis. Have White Spots. Suggestions?

I recently had ortho kinematic imaging of my lumbar spine. I am only 27 and after 2 years of every treatment possible, I am preparing for a spinal fusion and they are using it to see the stress the basic movements cause on my body. I have arthritis in my lumbar facet joints, mild spinal stenosis at l4/ through s1 and a central herniated disc at l5 s1. Flat back syndrome, Major sciatica and muscle spasms.....ortho kinematics was done under floroscopy and they noticed that since my mri, my lumbar spine is now curved, there were a lot of white spots on my left femoral head area as well as my facet joints and on my vertebrae. what are these white spots. I won't know my results till I see my specialist next month!! I will be getting a discogram soon as well. Please give me some insight!!
