A member asked:

How is ankylosing spondylitis differentiated from ddd? have diagnosis of ddd&psoriatic arthritis. leg weakness for years. new med for psa has eliminated. as?

A doctor has provided 1 answer

One is part of other: As is a inherited condition that results in calcification of the disk spaces throughout the spine. This gives the term "bamboo spine". This is a form of ddd. The leg weakness can come from canal or foraminal stenosis related to this. Ddd is a part of as. Imaging can help with the diagnosis and surgery is the last option. Surgery for ddd with as is more complicated.
