Can you tell me what a chronic 20% anterior compression deformity of t11 and t12 with no significant dorsal displacement the posterior wall.

Spine changes: Compression deformities are very common, but you might want to get your bone density checked. Osteoporosis is very common in women, and spinal compressions are one of the warning signs. Generally, you should get 1200 mg of calcium from your diet, or supplements, in small doses with vitamin d and c.

Compression fracture: I hope you're not reading your own xray report because it suggests an old osteoporotic fracture, at least if you don't recall injuring yourself. I say this because 34yo is kinda young for osteoporosis. Best to get a DEXA (dxa) scan to evaluate bone mineral density of your spine & hips. Then go to http://www.Shef.Ac.Uk/frax/ to calculate your risk for another fracture given known risk factors.
