Aim One of the major problems for systemic sclerosis ( SS c) patients is suggested to be articular involvement. Mostly involved joints in SS c were reported as wrist, carpometacarpal‐interphalangeal, foot, knee, hip and shoulder; however, there has been little knowledge on the sacroiliac joint. Our aim was to evaluate sacroiliac joint involvement in SS c. Methods Fifty‐seven SS c patients, 54 rheumatoid arthritis patients and 64 healthy subjects were included. Anteroposterior pelvic radiographs were obtained and graded twice by three blinded rheumatologists. One competent radiologist has re‐evaluated the X ‐ray results. The ASAS ( A ssessment of S pondylo A rthritis I nternational S ociety) scoring method was applied for grading sacroiliac involvement. Inflammatory back pain was also evaluated. Other clinical and laboratory data were collected as proposed by the E uropean S tudy G roup. Results In the SS c group sacroiliitis was found in 13 patients (23%) and was significantly different from RA patients (two patients, 4%), P = 0.003; and the healthy control group (one participant, 2%), P < 0.001. The frequency of inflammatory back pain in SS c patients with sacroiliitis (8/13 patients, 62%) was significantly higher in SS c patients without sacroiliitis (4/44 patients, 9%), P < 0.001. The SS c patients with sacroiliitis and with inflammatory back pain (8/57 patients, 14%) were regarded as axial spondyloarthritis overlap. Male gender, diffuse subtype, inflammatory back pain and high C ‐reactive protein levels (odds ratio: 1.069, 1.059, 1.059 and 3.698, respectively) were found to be the significant risk factors for sacroiliitis. Conclusion We suggest that, sacroiliitis may be a concern to be considered in SS c practice.
