The aim of this letter is to make public an unusual skeletal remain with classic features of ankylosing spondylitis (AS). Furthermore, human leucocyte antigen (HLA)-B27 sequences have been studied.
In the National Historical Museum in Stockholm there is a male skeleton (inventory no 14549). It was found during the excavation of St Clemens, a church ruin from the Middle Ages in Visby, Sweden. The preserved parts form a block, with smooth, continuous calcifications of the long ligaments and bony ankyloses of the intervertebral joints. Several ribs are fixed to the thoracic vertebrae through ankyloses of the costovertebral joints (fig 1). Also the sacroiliac joints are fused. The man lived sometime between 900 and 1300 AD. The details of this excavation were published in Swedish in 1911,1 and are therefore not generally known.
