I am 63 years old with severe osteoprosis, fell and had burst fracture of t12. My MRI after six weeks shows : there is further compression of central and superior and inferior endplates. There is further retropulsing of the bone posteriorly 8 mm. How close it is to spinal cord? There is effacement of the thecal sac with compression of anterior aspect of of the spinal cord. There is abutement of the transverse nerve roots bilaterally. I do not understand. Am I going to need surgery. I do not have much pain. I am clinically improving. Walking short distances with brace and walker.
