Celebrating 50 years of spondyloarthritis

It is 50 years since the original spondyloarthritis concept was proposed by Moll and Wright, and in November 2025, rheumatologists (and other health and research professionals in rheumatology and dermatology) gathered in Leeds, the birthplace of spondyloarthritis, to celebrate the milestone. Here, we report on the proceedings of the meeting, which looked back over the last 50 years, noted the current state of the art, and had a look at what might develop in the next 50 years.
