Spine Universe features multiple photographs of ankylosing spondylitis patients on its website, including a 66-year-old woman showing a forward head position and a forward posture. The site also features X-ray images of spine deformities caused by the condition.
Ankylosing spondylitis is a specific type of arthritis that results in swelling between the vertebrae of the spine and in the joints in between the spine and the pelvis, according to MedlinePlus. Symptoms of ankylosing spondylitis include continuous pain and stiffness in the lower back, reports WebMD. In some cases, spinal vertebrae fuse together, causing a rigid spine. Depending on the severity of changes to the spine, some patients develop a stooped-over posture. Systematic symptoms may include fatigue, loss of appetite and fever.
