There was this test they used to do for TB so once the result came back negative there was no need for any treatment. The result only took a couple of days to come through.

TB of the spine used to be much more common as recently as the 1950s. So as many A.S. sufferers were first seen by a orthopedic surgeons the first possible diagnoses was quite often TB spine.

I came across several sufferers of TB spine. Even after antibiotics became available as a cure for TB these patients still had a long way to go if the TB had spread to the spine. They often had to have major spinal surgery.
