Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Trauma is the commonest logical cause of a vertebra being pushed back on to the next one, being strongly connected to each other.
However, as in your case, if there is a likelihood of disease infiltration (by myeloma
) of the vertebra, it does not remain as strong and can cause retropulsed appearance even without or with slightest trauma.
So, I do agree with the radiology impression. And they are reporting a film. A clinician is the person who examines and knows the patient and gives opinion on its importance.
Please be guided by your treating doctor.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries.
Please ask for any clarifications before closing and rating this answer.
