Two studies, a cohort study and a case\u2013control study, were conducted using registry data on everyone who was residing in Sweden on December 31, 2005, and who was 50\u2009years of age or older at the time (n =\u20093,523,912). In the cohort study, individuals prescribed a BSD during the period 2006\u20132017 (n =\u2009217,387) were 1:1 matched with nonusers on birth year, sex, hip fracture status, and Swedish or foreign origin. In the case\u2013control study, individuals diagnosed with osteonecrosis during 2006\u20132017 (n =\u200912,614) were 1:1 matched with individuals without a diagnosis of osteonecrosis on birth year, sex, and Swedish or foreign background. In the cohort study, osteonecrosis was diagnosed in 983 BSD users and 214 nonusers (adjusted hazard ratio [aHR] 4.02; 95% CI, 3.32\u20134.87), during a mean treatment time of 2.8\u2009years. A similar association was observed in a subcohort where all individuals diagnosed with cancer (HR 4.82; 95% CI, 2.52\u20139.22). The greatest difference in incidence between BSD users and nonusers was observed in patients with a femoral neck fracture that was not treated with total hip arthroplasty or hemiarthroplasty (incidence rate difference, 77.8 cases per 10,000 person-years, p &amp;lt;\u2009.05). The risk of osteonecrosis was higher in users of denosumab (HR 1.93; 95% CI, 1.33\u20132.79) and users of zoledronic acid (HR 1.95; 95% CI, 1.31\u20132.91) than in users of other BSDs. The increased risk of osteonecrosis decreased after the end of therapy (p &amp;lt;\u2009.001 for time trend). The results were confirmed in the case\u2013control study. In summary, use of BSDs, especially more potent BSDs, is associated with increased risk of osteonecrosis of sites other than the jaw. This increased risk decreases after the final dose of BSD. \u00a9 2020 American Society for Bone and Mineral Research.<\/jats:p>","DOI":"10.1002\/jbmr.4040","type":"journal-article","created":{"date-parts":[[2020,5,7]],"date-time":"2020-05-07T10:48:10Z","timestamp":1588848490000},"page":"1703-1710","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Bone-Specific Drugs and Osteonecrosis of Sites Other Than the Jaw: A Nationwide Cohort Study"],"prefix":"10.1093","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2924-508X","authenticated-orcid":false,"given":"Peter","family":"Nordstr\u00f6m","sequence":"first","affiliation":[{"name":"Unit of Geriatric Medicine, Department of Community Medicine and Rehabilitation Ume\u00e5 University Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1904-6140","authenticated-orcid":false,"given":"Jonathan","family":"Bergman","sequence":"additional","affiliation":[{"name":"Unit of Geriatric Medicine, Department of Community Medicine and Rehabilitation Ume\u00e5 University Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcel","family":"Ballin","sequence":"additional","affiliation":[{"name":"Section of Sustainable Health, Department of Public Health and Clinical Medicine Ume\u00e5 University Ume\u00e5 Sweden"},{"name":"Unit of Geriatric Medicine, Department of Community Medicine and Rehabilitation Ume\u00e5 University Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabine","family":"Bj\u00f6rk","sequence":"additional","affiliation":[{"name":"Section of Sustainable Health, Department of Public Health and Clinical Medicine Ume\u00e5 University Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Nordstr\u00f6m","sequence":"additional","affiliation":[{"name":"School of Sports Science UiT The Arctic University of Norway Troms\u00f6 Norway"},{"name":"Section of Sustainable Health, Department of Public Health and Clinical Medicine Ume\u00e5 University Ume\u00e5 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,5,7]]},"reference":[{"issue":"25","key":"2024031419593541600_jbmr4040-bib-0001","doi-asserted-by":"crossref","first-page":"2407","DOI":"10.1056\/NEJMoa1808082","article-title":"Fracture prevention with zoledronate in older women with osteopenia","volume":"379","author":"Reid","year":"2018","journal-title":"N Engl J Med"},{"issue":"16","key":"2024031419593541600_jbmr4040-bib-0002","doi-asserted-by":"crossref","first-page":"3150","DOI":"10.1200\/JCO.2003.04.105","article-title":"Zoledronic acid versus placebo in the treatment of skeletal metastases in patients with lung cancer and other solid tumors: a phase III, double-blind, randomized trial\u2014the Zoledronic Acid Lung Cancer and Other Solid Tumors Study Group","volume":"21","author":"Rosen","year":"2003","journal-title":"J Clin Oncol"},{"issue":"18","key":"2024031419593541600_jbmr4040-bib-0003","doi-asserted-by":"crossref","first-page":"1799","DOI":"10.1056\/NEJMoa074941","article-title":"Zoledronic acid and clinical fractures and mortality after hip fracture","volume":"357","author":"Lyles","year":"2007","journal-title":"N Engl J Med."},{"issue":"9041","key":"2024031419593541600_jbmr4040-bib-0004","doi-asserted-by":"crossref","first-page":"1535","DOI":"10.1016\/S0140-6736(96)07088-2","article-title":"Randomised trial of effect of alendronate on risk of fracture in women with existing vertebral fractures.
