Intraoperative complications were present in 24 patients (8.9%). The overall 6-week complication rate after surgery was 35% (<jats:italic>n<\/jats:italic>\u2009=\u200995). The following variables were independently associated with 6-week complications: higher Genant grading of a present vertebral fracture (OR 1.41; 95% CI 1.04\u20131.95; <jats:italic>p<\/jats:italic>\u2009=\u2009.031), receiving intramuscular or intravenous steroids within a week prior to surgery (OR 3.97; 95% CI 1.79\u20139.06; <jats:italic>p<\/jats:italic>\u2009=\u2009.001), decompression surgery without fusion (OR 6.53; 95% CI 1.30\u201336.86; <jats:italic>p<\/jats:italic>\u2009=\u2009.026), higher creatinine levels (OR 2.18; 95% CI 1.19\u20135.60; <jats:italic>p<\/jats:italic>\u2009=\u2009.014), and lower calcium levels (OR 0.58; 95% CI 0.37\u20130.88; <jats:italic>p<\/jats:italic>\u2009=\u2009.013). A secondary surgery was indicated for 53 patients (20%), of which 13 (4.8%) took place within two weeks after the initial surgery. We additionally discovered factors associated with retreatments, which are elucidated within the manuscript.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The goal of surgical treatment for MM bone disease is to enhance patient quality of life and reduce symptom burden. However, postoperative complication rates remain relatively high after spine surgery in patients with MM, likely attributable to both inherent characteristics of the disease and patient comorbidities. The risk for complications and secondary surgeries should be explored and a multidisciplinary approach is crucial.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00586-023-07903-1","type":"journal-article","created":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T15:28:55Z","timestamp":1694705335000},"page":"4335-4354","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Analysis of complications and revisions after spine surgery in 270 multiple myeloma patients with spinal involvement"],"prefix":"10.1007","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3962-6871","authenticated-orcid":false,"given":"H.","family":"Zijlstra","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0885-1750","authenticated-orcid":false,"given":"R.
