Hormone therapy and SERMs bone health menopause reduce postmenopausal bone loss and fracture risk; systemic estrogen in randomized trials (Women’s Health Initiative) was associated with about a 30–35% lower hip fracture rate, while early postmenopausal bone loss commonly averages 1–2% of bone mineral density per year. These therapies have different targets: systemic estrogen prevents both vertebral and nonvertebral fractures, whereas selective estrogen receptor modulators such as raloxifene primarily prevent vertebral fractures and improve spine BMD. Use is individualized by age, time since menopause, and baseline fracture risk assessed by DXA and FRAX; systemic estrogen is typically recommended for women within 10 years of menopause for symptom control and bone protection.

Mechanistically, systemic estrogen reduces menopause bone loss by decreasing osteoclast-mediated resorption through modulation of the RANKL/osteoprotegerin pathway and by preserving spine and hip bone mineral density; estrogen therapy bone mineral density gains of 2–4% over one to two years are commonly observed on DXA. Selective estrogen receptor modulators such as raloxifene act as estrogen agonists in bone and antagonists in breast and uterus, reducing vertebral fracture risk without increasing endometrial cancer risk. Clinicians use DXA scans and FRAX risk assessment, and interpret trials such as the Women’s Health Initiative and MORE to balance fracture prevention against safety endpoints including venous thromboembolism and lipid effects. Bone turnover markers (CTX, P1NP) can aid early response assessment.

A common clinical pitfall is using relative risk reductions without converting to absolute risk or NNT. For example, for a woman with a 10‑year major osteoporotic fracture risk of 20%, a 30% relative reduction with systemic estrogen translates to a 6 percentage‑point absolute reduction (20% to 14%), an NNT of about 17 over ten years; that framing changes the HRT risks benefits bone density trade-off. Treating 'HRT' as a single entity also misses important differences: oral estrogen elevates venous thromboembolism risk more than transdermal formulations, and selective estrogen receptor modulators osteoporosis data show clear vertebral protection but no consistent hip fracture benefit, as seen with raloxifene bone fractures analyses, clinically. Decisions should integrate comorbidities, life expectancy, and patient preferences.

Practical application: assess baseline 10‑year fracture risk with FRAX and obtain DXA before initiating therapy; present absolute risk reductions and NNT when discussing options. For symptomatic women within ten years of menopause, systemic estrogen—preferably transdermal if venous thromboembolism risk factors exist—provides broad fracture prevention and symptom control. For women with vertebral fracture risk or increased breast cancer concerns, raloxifene offers vertebral protection without endometrial stimulation but not reliable hip fracture prevention. Ongoing monitoring of BMD, reassessment of fracture risk, and shared decision documentation are essential.
