Hysteroscopic detection of heterotopic intrauterine bone formation

The diagnosis and management of heterotopic intrauterine bone formation was performed hysteroscopically in nine patients. The presenting symptom was secondary infertility in seven, pelvic pain in one and passage of bone fragments in one. All nine patients had a history of spontaneous and therapeutic abortion. Hysteroscopy was more accurate than hysterosalpingography in detecting the condition. Four pregnancies occurred in the seven infertile patients following removal of the bone. In four of nine cases there was clear evidence of remaining bone fragments after the initial removal.
