Abstract

During pregnancy, some women suffer from low back pain due to pelvic ring instability. While pelvic ring instability is generally investigated by using x-ray image, this is not a suitable examination for pregnant women due to the risk of irradiation. Consequently, a study investigating the effectiveness of ultrasound in the diagnosis of pelvic ring instability was performed. Using ultrasound, the difference in front and back displacement of the pubic tubercle can be seen by having pregnant women lie on their back or changing position of their legs by flexing their hip joint. Furthermore, symphyseolysis can be seen as an area of high density. These findings show that the ultrasound examination is suitable for the diagnosis of pelvic ring instability. Since it is, however, not yet an established method, further study is necessary for selecting the best method to diagnose these pathologic findings.
