While emerging evidence has elucidated its pathophysiological roles in oncology, neurodegenerative disorders, and metabolic diseases, its mechanistic involvement and therapeutic potential in musculoskeletal disorders-including osteoarthritis, rheumatoid arthritis, osteoporosis, intervertebral disc degeneration, ankylosing spondylitis, bone tumors, skeletal muscle atrophy, and osteonecrosis of the femoral head (ONFH)-remain largely unexplored. This comprehensive review synthesizes current knowledge on the molecular mechanisms underlying cuproptosis in musculoskeletal pathophysiology, its potential as a disease-modifying factor, and the translational challenges that must be addressed before its clinical application. Furthermore, we highlight critical knowledge gaps and propose novel research directions that may help advance this emerging field.<\/jats:p>","DOI":"10.3389\/fcell.2026.1790043","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T05:48:59Z","timestamp":1779256139000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Musculoskeletal disorders: does cuproptosis hold the key?"],"prefix":"10.3389","volume":"14","author":[{"given":"Chenglong","family":"Wang","sequence":"first","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dengshang","family":"Liu","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Ye","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liqiang","family":"Cui","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuangquan","family":"Gong","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongjun","family":"Liu","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiming","family":"Xie","sequence":"additional","affiliation":[{"name":"Spinal Surgery Department, Mianyang Orthopaedic Hospital","place":["Mianyang, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,5,20]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"407","DOI":"10.1007\/s12011-011-9109-7","article-title":"Plasma selenium, zinc, copper and lipid levels in postmenopausal Turkish women and their relation with osteoporosis","volume":"144","author":"Arikan","year":"2011","journal-title":"Biol.
