Symptomatic intrauterine retention of fetal bones

Four patients with symptomatic intrauterine retention of fetal bones are discussed. Presenting complaints included infertility, irregular vaginal bleeding, vaginitis, and spontaneous passage of fetal bones. Two patients had uterine anomalies; 1 patient had a retained twin pregnancy. Pelvic ultrasound and x-ray films of the pelvic cavity are helpful in making a diagnosis. Hysteroscopy is invaluable both in confirming the diagnosis and in achieving successful removal of fetal bone.
