Discrepancies abound in the literature regarding the anatomy and incidence of the C1 dorsal roots, ganglia, and rami. The present study was performed to elucidate further the detailed anatomy of these structures and to review their clinical relevance. Thirty-adult cadavers were used for this study. The mean age for this group was 72 years. C1 and C2 spinal nerves were identified in 100% of the specimens examined. In 46.6% of specimens, C1 dorsal rootlets were identified and of these, 28.5% had an associated dorsal root ganglion. In 50% of specimens, the spinal accessory nerve joined with dorsal rootlets of C1. C1 in these cases did not possess a dorsal root ganglion. There were no significant differences between left sides, gender, and age (P > 0.05). Additional knowledge regarding the C1 dorsal roots, ganglia, and rami may be of use to the clinician who treats various pain syndromes including medically and surgically intractable occipital neuralgia.
关于C1背根、神经节和分支的解剖结构及发生率，文献中存在诸多差异。本研究旨在进一步阐明这些结构的详细解剖，并探讨其临床意义。本研究使用了30具成年尸体。该组的平均年龄为72岁。在100%的检查标本中均识别出了C1和C2脊神经。在46.6%的标本中识别出了C1背根丝，其中28.5%伴有背根神经节。在50%的标本中，副神经与C1的背根丝相连。在这些病例中，C1没有背根神经节。左侧、性别和年龄之间无显著差异（P>0.05）。关于C1背根、神经节和分支的更多知识可能对治疗各种疼痛综合征（包括药物和手术治疗棘手的枕神经痛）的临床医生有用。
