Abstract：
In 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.
The 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.
During 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.
In a Hispanic Puerto Rico population, the most prevalent operated degenerative cervical disc levels were C5-C6 and C4-C5.

摘要：
背景：在文献中，退行性颈椎间盘突出症被认为在C5-C6和C6-C7水平更常见。这项研究旨在评估西班牙裔波多黎各人群中退行性颈椎间盘突出症患者的手术颈椎水平患病率。
方法：波多黎各大学神经外科数据库用于确定在2006年1月1日至2020年12月31日的15年期间因退行性颈椎间盘突出而接受前路颈椎间盘切除术的患者。分析每位患者的手术宫颈水平。
结果：在研究期间，409例患者接受了退变性颈椎间盘突出症手术治疗。在663个治疗水平中，有88名患者（50.8％）在一个以上的颈椎水平出现椎间盘突出症。该西班牙裔人群中最普遍的宫颈水平是C5-C6（34.8％）和C4-C5（28.1％）。C6-C7水平涉及18.9%的手术水平，C3-C4水平为17.3%。C7-T1水平仅占手术水平的0.6％，C2-3水平为0.3%。该队列包括51.3%的男性和48.7%的女性，男女比例为1.05:1。女性的中位年龄为56.5岁（26-82岁），男性为59.0岁（31-85岁）。无论男女，手术后的颈椎间盘在48至66岁之间最常见。
结论：在西班牙裔波多黎各人口中，最普遍的手术退行性颈椎间盘水平是C5-C6和C4-C5。
