• Transilial bone biopsy confirmed heparin-induced osteopenia in a 23-year-old postpartum patient. Histomorphometric measurements during the reversible stage of bone disease that followed discontinuation of the heparin sodium therapy revealed signs of recovery; these were superimposed on a loose trabecular structure typical of osteoporosis. The histomorphometric evidence of recovery correlated well with signs of clinical improvement. In the majority of patients, heparin therapy during pregnancy is innocuous; however, discontinuation of treatment is recommended at the earliest signs of osteoporosis.
