LBP disproportionately impacts postmenopausal women relative to age-matched men, suggesting a role for sex-specific biological factors. Although the mechanisms underlying this disparity are not fully understood, hormonal imbalance during menopause may contribute to LBP pathophysiology. This narrative review aimed to elucidate the impact of menopause on LBP, with emphasis on hormonal effects on spinal tissues and systemic processes. A literature search was conducted, followed by screening of titles, abstracts, and full texts of original clinical studies, preclinical research using human or animal samples, and relevant reviews. Rigour and reproducibility were evaluated using the ARRIVE Guidelines and the Modified Downs &amp; Black Checklist. Evidence indicates that menopause is associated with changes in intervertebral discs, facet joint, ligamentum flavum, skeletal muscle, sympathetic innervation, and systemic systems such as the gut microbiome. However, most findings are correlational rather than causal. Evidence supporting hormone replacement therapy for LBP remains inconclusive, whereas exercise and other treatments, including parathyroid hormones, show more consistent benefits. Future studies should focus on causal mechanisms and adhere to rigour guidelines to improve translational potential.<\/jats:p>","DOI":"10.3390\/cells15020148","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T11:01:14Z","timestamp":1768388474000},"page":"148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Impact of Menopause and Associated Hormonal Changes on Spine Health in Older Females: A Review"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5183-7658","authenticated-orcid":false,"given":"Julia","family":"Chagas","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, PA 15213, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9039-4183","authenticated-orcid":false,"given":"Gabrielle","family":"Gilmer","sequence":"additional","affiliation":[{"name":"Medical Scientist Training Program, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gwendolyn","family":"Sowa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, PA 15213, USA"},{"name":"Department of Physical Medicine and Rehabilitation, University of Pittsburgh, Pittsburgh, PA 15213, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1265-8921","authenticated-orcid":false,"given":"Nam","family":"Vo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, PA 15213, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,14]]},"reference":[{"key":"ref_1","first-page":"105","article-title":"Low Back Pain\u2014From Definition to Diagnosis","volume":"58","author":"Vrbanic","year":"2011","journal-title":"Reumatizam"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"777","DOI":"10.1016\/j.mcna.2014.03.005","article-title":"Acute and Chronic Low Back Pain","volume":"98","author":"Patrick","year":"2014","journal-title":"Med.
