Hip avascular necrosis in a healthy pregnant woman: A case report and review of literature.

Abstract

BackgroundHip pain during pregnancy is very common, but hip avascular necrosis represents a very rare entity.Case reportWe report a rare case of a healthy30-year-old female patient pregnant with twins, that suffered right hip avascular necrosis in the peripartum period, her symptoms were initially neglected as a benign cause of hip pain, this led to aggressive treatment at a young age.DiscussionWith less than 100 cases reported in the literature, pregnancy is not a well-known risk factor for femoral head avascular necrosis and it should be differentiated from one of the more common hip pathologies in pregnancy which is the so-called “Pelvic pain syndrome” and transient osteoporosis of the hip.ConclusionHaving a high index of suspicion and low threshold for MRI imaging in a pregnant woman with hip pain is a must to prevent such complications.
