Anatomical terminology

In the human body, the lateral sacrococcygeal ligament is a bilaterally paired ligament extending between the transverse process coccyx, and the inferolateral angle of the sacrum.[1] The ligament forms a foramen for[2][1] an anterior ramus[1] of the fifth sacral nerve (S5).[2][1] The ligament may become ossified.[1] There may be up to three lateral sacrococcygeal ligaments on either side of the sacral hiatus.[3]

Function

[edit]

Together with the anterior, posterior, and intercornual sacrococcygeal ligaments, the lateral sacrococcygeal ligaments stabilize the sacrococcygeal symphysis (i.e. the joint between the sacrum and the coccyx).[2]
