Ankylosing spondylitis is a type of arthritis in which there is long-term inflammation of the joints of the spine.

Other forms of arthritis may sometimes also lead to ankylosis, including rheumatoid arthritis and reactive arthritis
Osteoarthritis usually confers osteophyte formation, which may eventually fuse across joints.
Osteoarthritis is believed to be caused by mechanical stress on the joint and low-grade inflammatory processes.

Arthrodesis is the intentional creation of ankylosis in a joint.

Noma—a gangrenous disease still widespread among malnourished children living on the borders of the Sahara desert—can cause ankylosis of the maxilla and mandible, impairing the ability to speak and eat.
