Pregnancy-related osteoporotic vertebral compression fractures in two patients treated with low-molecular-weight heparin during pregnancy: case reports.

Pregnancy-related osteoporosis (PRO) is an uncommon metabolic bone disease that can result in vertebral fragility fractures. Here we report two cases of young women who had been previously treated with LMWH-enoxaparin and were diagnosed with PRO with vertebral fragility fractures after delivery. In first case report, a 33-year-old primigravid woman who was treated with 40 mg/day of enoxaparin for eight months to prevent venous thromboembolism was presented.
