当院で経験した妊娠後骨粗しょう症の１例

Abstract

Post-pregnancy osteoporosis, which was reported for the first time by Nordin in 1955 originates from back pain and vertebral compression fracture during pregnancy or delivery. This disease is so rare that only a few reports are available in the literature. According to these reports, subjects as young as 20-30 years at the onset are predominant and about 80% of them develop the osteoporosis following their first experience of pregnancy. There is a strong correlation with lactation, which is, however, not always responsible for the present disease. The disease is self-limiting, and interruption of lactation and conservative treatment lead to remission within several months with a favorable prognosis.Recently, we experienced a 32-year-old woman who developed back pain 2 months after delivery of her second child and had a lumbar compression fracture, which, however, was relieved by conservative treatment. We would like to report the present case with particular emphasis on the change in bone mineral density, as measured using Dual energy X-ray Absorptiometry and a review of the relevant literature.
