Case of retained fetal femur acting as inert intrauterine device

Abstract

Introduction: Retention of fetal bones is a rare but documented complication after dilation and curettage (D and C). Previous case reports have described instances of retention of multiple fetal bones or bony fragments. Case Report: We are presenting a case of a female with 1.5 years of secondary infertility due to retention of a single, intact, fetal femur bone following a therapeutic abortion 13 years prior. The bone was incidentally identified on follicle check ultrasound and was removed via hysteroscopy. The patient conceived one year later, which progressed to a full-term pregnancy. Conclusion: Retained bony fragments or intact bones should be considered as a possible cause of secondary infertility following therapeutic abortions, emphasizing the importance of ultrasound imaging in preliminary secondary infertility workup.
