spondolosis with myelopathy, i had 2 spinal fusions, what does 30 flexion mean?

Answer 1

It refers to the angle/extension

Dynamic factors may be important in that normal flexion and extension of the cord may aggravate spinal cord damage, initiated by static compression of the cord. During flexion, the spinal cord lengthens, which stretches it over ventral osteophytic bars. During extension, the ligamentum flavum may buckle into the cord, pinching the cord between the ligaments and anterior osteophytes

Answer 2

30 flexion?? 30 what? 30%? 30 degrees? There's not enough information given to answer the question.
My best guesses would be either 30% of normal flexion or 30 degrees of flexion, either of which would indicate significant limitation of motion forward of the spine. That would be an expected result from 2 spinal fusion surgeries.
