Abstract

Abstract: Femoral neck fractures resulting from pregnancy‐associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy‐associated osteoporosis in a 38‐year‐old primiparous patient with pre‐existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post‐partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip. Based on our experience, we propose that pregnancy‐associated osteoporosis might be present in femoral neck fractures attributed to transient osteoporosis of the hip in pregnancy. Conversely, bone status should be carefully and accurately estimated in cases of potential transient osteoporosis of the hip in pregnancy to reduce future fracture risk.
