• A survey of more than 17,000 women (10,981 met the analysis criteria), led by Jocelyn Wittstein, MD, an orthopedic surgeon at Duke University School of Medicine, compared frozen-shoulder (adhesive capsulitis) rates in hormone-therapy users vs non-users: 47% were using hormone therapy and 53% were not.
• 3.2% of women using hormone therapy reported a frozen-shoulder diagnosis after starting it, vs 26.8% of women not using hormone therapy – frozen shoulder was about eight times more common among non-users. The association stayed statistically significant after accounting for race, diabetes, and thyroid disease.
• The study is a self-reported survey, not a review of medical records; it did not capture hormone-therapy formulation or dose, and at the time of the interview had been presented at the American Orthopaedic Society for Sports Medicine annual meeting (July 2026) but not yet published in a peer-reviewed journal. It shows a strong association, not proof that hormone therapy prevents frozen shoulder.
• Wittstein on mechanism: estrogen has anti-inflammatory effects on the lining of the shoulder joint, and appears to help regulate fibroblasts in the joint lining; as estrogen declines those cells may become overactive, contributing to inflammation, thickening, and stiffness. There is basic-science support, but more research is needed to quantify the hormonal role. Frozen shoulder is likely multifactorial, and women on hormone therapy can still get it.
• Among women who started hormone therapy after a frozen-shoulder diagnosis but before their symptoms resolved, 57% (445 women) reported improvement after starting hormone therapy – explicitly not interpretable as proof of effect, because they may also have had a steroid injection or physiotherapy, or the condition may already have been improving on its own.
• 44% of women in the study reported hot flashes, night sweats, or both (27% mild, 63% moderate, 10% severe); women with severe menopausal symptoms scored significantly worse on general physical-function measures, though not specifically on frozen-shoulder function. Women with a history of breast cancer were excluded because of distinct risk factors (chemotherapy-induced earlier menopause; aromatase-inhibitor musculoskeletal syndrome).
