Ankylosing spondylitis is also known as Marie-Strumpell disease or Bechterew’s disease. It’s a form of inflammatory arthritis that primarily affects your spine.
In cases where arm pain is caused by a cervical disc bulge or herniation or from degenerative changes producing osteophytic spurs (aka “bone spurs”), the pain is called cervical radiculopathy.
An artificial disc (also called a disc replacement, disc prosthesis or spine arthroplasty device) is a device that is implanted into the spine to imitate the functions of a normal disc (carry load and allow motion).
