This individual has ankylosing spondylitis (FA2020 p469)
Ankylosing spondylitis is a seronegative spondyloarthritis (meaning not associated with rheumatoid factor) more common in men which has symmetric involvement of the spine and sacroiliac joints. Symptoms include inflammatory lower back pain which improves with exercise and is worsened by immobility. X-rays of the sacroiliac joint would help confirm the diagnosis by showing ankylosis (joint fusion) characteristic of this disorder.

goooooseThat^ and RA typically involves the symmetric MCPs and PIPs, there's also no mention of morning stiffness that improves with use. Ankylosing spondylitis is more common in young males too+
