Model	Figure	Comment
Normal model	—	The original model, representing a healthy patient with no AS.
AS, no fracture	—	Model with elements representing the ossification of parts of the intervertebral discs. This model represents the nonfractured AS patient.
AS, fracture (at C6C7 disc level)	—	Model with removed elements in the disc ossification at the C6C7 disc level, representing a fracture.
