The current surgical standard of care, anterior cervical discectomy and fusion (ACDF), allows for adequate decompression with good outcomes; however, this alters biomechanical stability and can eventually lead to adjacent segment disease and reoperation. By preserving motion at the pathological level, CDR might reduce the development of adjacent segment disease and the associated morbidity of reoperation. The aim of this study was to evaluate long-term functional outcomes with CDR compared with ACDF using a large federated electronic health record network.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>The TriNetX database was queried for all patients \u2265 18 years of age who underwent CDR or ACDF for degenerative indications. Propensity score matching based on demographic and clinical characteristics was performed using a 1:1 ratio. Cohorts were evaluated by calculating relative risk of functional and clinical outcomes at multiple time points from 6 months to 5 years. Kaplan-Meier survival curves were used to examine reoperation and adjacent segment disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>After matching, 9458 patients (mean age 48 years) were included in both the ACDF and CDR groups. At all follow-up time points, there was a significantly lower risk of anterior reoperation (RR 0.62, 95% CI 0.52\u20130.74; p &lt; 0.001) and new-onset cervical pain (RR 0.64, 95% CI 0.55\u20130.73; p &lt; 0.001) among patients who underwent CDR compared with those who underwent ACDF. At the 1-, 2-, and 5-year follow-ups, there was significantly lower risk of surgical site infection (RR 0.62, 95% CI 0.48\u20130.78; p &lt; 0.001) in the CDR group. After 2 years, there was no difference in codes for acquired kyphosis or lordosis of the cervical spine between the two groups (p &gt; 0.05), and after 5 years, there was significantly lower risk of opioid use (RR 0.66, 95% CI 0.54\u20130.82; p &lt; 0.001) among patients who underwent CDR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>These propensity-matched results suggest that CDR offers superior long-term outcomes compared with ACDF. While these findings suggest potential advantages associated with motion-preserving surgery, the results should be interpreted cautiously given the inherent limitations of retrospective electronic health record\u2013based analyses. As the US population continues to age and technologies continue to improve, CDR should be considered as a viable alternative to motion-sacrificing procedures for the treatment of degenerative cervical spine pathologies. Future studies should investigate long-term clinical and radiographic outcomes to further elucidate the findings of this study.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2026.3.focus2631","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T00:01:02Z","timestamp":1782259262000},"page":"E5","source":"Crossref","is-referenced-by-count":0,"title":["Outcomes after cervical disc replacement compared with anterior cervical discectomy and fusion at medium- to long-term follow-up: a propensity score\u2013matched TriNetX analysis"],"prefix":"10.3171","volume":"61","author":[{"given":"Omar","family":"Sbaih","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, Georgetown University Medical School, Washington, DC;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Meade","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, New England Baptist Hospital, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nithin","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"DiCiurcio","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruchir","family":"Nanavati","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blake","family":"Delgadillo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hunter","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Middleton","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shannon","family":"Fehr","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Jefferson Health, Stratford, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rohin","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Rochester, New York; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan J.","family":"Stone","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Rochester, New York; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory","family":"Schroeder","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, Rothman Orthopedic Institute, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher K.","family":"Kepler","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, Rothman Orthopedic Institute, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barrett","family":"Woods","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, Rothman Orthopedic Institute, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"4","key":"b1","series-title":"J Neurosurg Spine","first-page":"569","article-title":"Comparison of anterior cervical discectomy and fusion versus artificial disc replacement for cervical spondylotic myelopathy: a meta-analysis","volume":"37","author":"Chang CJ","year":"2022","unstructured":"Chang CJ, Liu YF, Hsiao YM,  Comparison of anterior cervical discectomy and fusion versus artificial disc replacement for cervical spondylotic myelopathy: a meta-analysis.
