Tomography of the sacroiliac joints (SIJ) was performed in 72 patients with rheumatoid arthritis (RA) and in 50 controls. Twenty-seven rheumatoid patients (38%) showed typical sacroilitis with predominantly severe intraarticular ankylosis and subchondral erosions. Fourteen patients (19%) had a probable sacroilitis with mild erosions and intraarticular ankylosis and concomitant degenerative changes. Fifteen patients (21%) showed predominantly degenerative changes and 16 RA patients (22%) had no radiological manifestation of the SIJ. There was no relation between typical sacroilitis and age of patients, duration of disease, rheumatoid factor, Steinbrocker's stage and frequency of HLA B27.
对72例类风湿性关节炎（RA）患者和50名对照者进行了骶髂关节（SIJ）断层扫描。27例类风湿患者（38%）表现出典型的骶髂关节炎，主要为严重的关节内强直和软骨下侵蚀。14例患者（19%）可能患有骶髂关节炎，有轻度侵蚀和关节内强直以及伴随的退行性改变。15例患者（21%）主要表现为退行性改变，16例RA患者（22%）骶髂关节无放射学表现。典型骶髂关节炎与患者年龄、病程、类风湿因子、Steinbrocker分期及HLA B27频率之间无关联。
