Obese patients undergoing anterior cervical discectomy and fusion have higher complication rates, but the procedure remains effective in this population. The aim of this study was to determine the safety and efficacy of CDA in appropriately selected obese patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>This single-institution retrospective cohort study included adult patients who underwent CDA from July 2015 to December 2020. Patients were included if they had baseline and at least 4-year postoperative patient-reported outcome measures (PROMs), including the Neck Disability Index (NDI), numeric rating scale (NRS) for neck pain and arm pain, EQ-5D, and North American Spine Society patient satisfaction questionnaire. Demographic, intraoperative, and postoperative characteristics were collected.

Obese patients were more likely to have diabetes mellitus and a higher American Society of Anesthesiologists class. There were no significant differences in the operative duration, hospital length of stay, estimated blood loss, 90-day readmission rate, 90-day return to the operating room rate, or time to return to work. The mean follow-up duration was 5.6 years in the nonobesity group and 5.1 years in the obesity group. Both groups significantly improved across all PROMs postoperatively (p &lt; 0.001). There were no significant differences in preoperative or postoperative NDI, NRS neck pain, NRS arm pain, or EQ-5D scores. There were no significant differences in patient satisfaction with surgery (89.8% satisfied in nonobesity group and 85.3% satisfied in obesity group; OR 1.52, 95% CI 0.40\u20135.71).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>CDA is a safe and effective motion-sparing procedure for cervical radiculopathy and myelopathy in appropriately selected obese patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2026.4.focus2611","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T00:01:07Z","timestamp":1782259267000},"page":"E7","source":"Crossref","is-referenced-by-count":0,"title":["Cervical disc arthroplasty as a safe and effective procedure for obese patients"],"prefix":"10.3171","volume":"61","author":[{"given":"Daniel","family":"Zeitouni","sequence":"first","affiliation":[{"name":"Atrium Health Neurological Surgery, Charlotte;"},{"name":"Carolina Neurosurgery & Spine Associates, Charlotte; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Landon M.","family":"Burton","sequence":"additional","affiliation":[{"name":"Wake Forest School of Medicine, Wake Forest University, Charlotte, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trent","family":"VanHorn","sequence":"additional","affiliation":[{"name":"Atrium Health Neurological Surgery, Charlotte;"},{"name":"Carolina Neurosurgery & Spine Associates, Charlotte; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Pfortmiller","sequence":"additional","affiliation":[{"name":"Atrium Health Neurological Surgery, Charlotte;"},{"name":"Carolina Neurosurgery & Spine Associates, Charlotte; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul K.","family":"Kim","sequence":"additional","affiliation":[{"name":"Atrium Health Neurological Surgery, Charlotte;"},{"name":"Carolina Neurosurgery & Spine Associates, Charlotte; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"4","key":"b1","series-title":"Neurospine","first-page":"296","article-title":"The option of motion preservation in cervical spondylosis: cervical disc arthroplasty update","volume":"15","author":"Chang CC","year":"2018","unstructured":"Chang CC, Huang WC, Wu JC, Mummaneni PV.
