We performed a 5-year propensity scoring-matched analysis of 276 patients undergoing anterior versus posterior cervical surgery at one institution. Methods: We performed propensity score matching on financial data from 276 patients undergoing 1–3 level anterior versus posterior cervical fusions for degenerative disease (2015–2019). Results: We found no significant difference between anterior versus posterior approaches for hospital costs ($42,529.63 vs. $45,110.52), net revenue ($40,877.25 vs. $34,036.01), or contribution margins ($14,230.19 vs. $6,312.54). Multivariate regression analysis showed variables significantly associated with the lower contribution margins included age (β = −392.3) and length of stay (LOS; β = −1151). Removing age/LOS from the analysis, contribution margins were significantly higher for the anterior versus posterior approach ($17,824.16 vs. $6,312.54, P = 0.01). Conclusion: Anterior cervical surgery produced higher contribution margins compared to posterior approaches, most likely because posterior surgery was typically performed in older patients requiring longer LOS.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/08a794ab-b6fc-4bca-91ad-44c30a3a81cd/featured/hero-1781561171819.png","publishDate":"2022-07-15T00:00:00.000Z","doi":"10.25259/SNI_497_2022","categories":["Spine","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/07/11723/SNI-13-300.pdf"}
