Abstract
We report a case of lumbar compression fracture due to post-pregnancy osteoporosis. The patient was a 24-year-old female, who complained slight low back pain after her first delivery.
About two months after the delivery, an attack of low back pain occured. Plain X-ray showed fracture (compression type) of the L2 vertebral body. Double energy X-ray absorptiometry (DEXA) showed a reduction of bone mineral density (BMD) to 0.692g/cm2.
The patient was treated with four weeks bed rest followed by bracing and rehabilitation. She refrained from nursing her baby, and calcium, vitamin D, and hormonal agents were administered. She recovered uneventfully and four months later, BMD had increased to 0.802g/cm2 on DEXA.
The cause of her fracture might have been bone demineralization due to pregnancy, child birth and nursing her baby. Another reason was the small volume of her peak bone mass which may have been due to other aspects of her life style.
