[Rheumatic spondylodiscitis in spondylarthropathies]. / Spondylodiscite rhumatismale au cours des spondylarthropathies.

The involvement of enthesis like disc space is the typical lesion of spondylarthropathies. Out of 240 patients with spondylarthropathies, 10 (7 M, 3 W; mean age: 37 years) have spondylodiscitis, affecting a total of 13 disc spaces: 1 cervical, 2 thoracic, 10 lumbar. The mean duration of spondylarthropathy at the time of diagnosis of spondylodiscitis is 10 years. Spondylodiscitis has a variable clinical presentation: painful (6 cases), asymptomatic (4 cases). Its coexistence with typical radiographic signs of spondylarthropathy added to the exclusion of bacterial origin, permit to link it to spondylarthropathy. Its evolution is generally favourable.
