The purpose of this study is to characterize the MRI changes of the sacroiliac joints (SIJs) during pregnancy and following labor and to correlate them with clinical symptoms. Ninety-three pelvic and hip MRIs of pregnant and  <=6 months postpartum @entity1 were retrospectively evaluated (Berlin method), for the presence of acute and structural SIJ changes. A telephone questionnaire focusing on @entity158 characterization, co-morbidities, and clinical outcome was conducted with 52 subjects. Findings were correlated with pregnancy week/postpartum time and clinical parameters. SIJ-bone @entity236 (BME) and @entity2001 were a prevalent peripartum finding (46/26 % subjects, respectively), and their frequency increased with pregnancy age. Also, BME, joint fluid, @entity2585 , and @entity4932 total score were correlated with pregnancy age/postpartum time (r   =   0.2-0.31, P   =   0.013-0.036). Significant correlation was noted between BME and @entity2001 scores (r   =   0.485, P   <   0.0001). A sizable proportion of @entity1 showed diffuse SIJ BME (7.6 %) and this correlated with slower resolution of symptoms. Indeed, in half of the cases in which MRI was performed due to pregnancy-induced @entity1643 ( @entity1643 ) and diffuse BME was found- @entity5145 ensued. In conclusion, pregnancy and puerperium are associated with a host of acute findings in and around the SIJ, including BME, @entity2585 , and @entity4932 , reflecting most probably, mechanical load and hormonal changes. While the vast majority of symptoms abate within weeks to several months postpartum, 3.8 % of @entity1 go on to develop @entity5145 . Diffuse SIJ BME and the presence of risk factors for @entity5145 are predictive of a chronic course.
