My ortho dr. Says I have a 40 degree curve, a radiologist say 56 degree curve. The radiologist is stoping me from becoming a fireman who do I lisite?

Ortho and rad agree. The orthopedic surgeon and radiologist have to come to an agreement as to the degree of curvature. Is there a limit set by you were fireman’s organization?
Less difference. Measuring scoliosis depends on landmarks used to measure curvature. Interobserver variation should be about 5 degrees. The orthopedic physician usually determines curvature that is used for clinical decisions, surgery etc. The same curvature is on image viewed by both physicians. Agreement should be closer as to severity of curve.
Communicate. Have the orthopedic surgeon call the radiologist. I am sure they can discuss the case and settle on curvature.
