Painful pelvic joints induced by a levonorgestrel‐releasing intrauterine system

The normally occurring loosening of the pelvic joints with separation of the symphysis during pregnancy may give rise to pain over the symphysis pubis or/and over the sacroiliac joints. In contrast, increased mobility between the pubic bones and pelvic pain without any direct connection with pregnancy is rare and its etiology is unclear. The following is a report of a patient who experienced symphysiolysis‐like pelvic pain following the use of a levonorgestrel‐releasing intrauterine system.
