摘要：
The alar ligament is one of the two strongest ligaments stabilizing the craniocervical junction. The literature describes many variations of the attachment, insertion, shape, and orientation of the alar ligament and an understanding of these variations is vital as they can lead to altered biomechanics or misinterpretation on imaging. Herein, we report, to our knowledge, the first case of duplication of the alar ligaments and discuss the anatomical variations present in the literature.
