BackgroundIn the literature, degenerative cervical disc herniation is considered to occur more frequently at the C5-C6 and C6-C7 levels. This study aimed to evaluate the operated cervical level prevalence among patients with degenerative cervical disc herniation in a Hispanic Puerto Rico population.MethodsThe University of Puerto Rico Neurosurgery database was used to identify patients who underwent anterior cervical discectomy for degenerative cervical disc herniation during a 15-year period from January 1, 2006 until December 31, 2020. Operated cervical levels for each patient were analyzed.ResultsDuring the study period, 409 patients were operated on for degenerative cervical disc herniation. Two hundred-eight patients (50.8%) had disc herniations at more than 1 cervical level for 663 treated levels. The most prevalent cervical levels in this Hispanic population were C5-C6 (34.8%) and C4-C5 (28.1%). The C6-C7 level was involved in 18.9% of the operated levels, and the C3-C4 level in 17.3%. The C7-T1 level was involved in only 0.6% of the operated levels, and the C2-3 level in 0.3%. The cohort included 51.3% of men and 48.7% of women, with a men-to-women ratio of 1.05:1. The median age of females was 56.5 (range 26-82) and 59.0 (range 31-85) for males. Operated cervical discs were most common between the ages of 48 and 66 years for either sex.ConclusionsIn a Hispanic Puerto Rico population, the most prevalent operated degenerative cervical disc levels were C5-C6 and C4-C5.Copyright © 2023 Elsevier Inc.
