The denticulate ligaments, also known as dentate ligaments, are triangular shaped ligaments that anchor the spinal cord along its length, at each side, to the dura mater. The bases of the ligaments arise in the pia mater and they are firmly attached to the arachnoid mater and dura mater at the apex. They have 21 attachments per side. Their tooth-like appearance originates the word which derives from Latin denticulatus, from denticulus ‘small tooth’. The denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column.

- Le ligament dentelé ou ligament denticulé est une structure anatomique située dans le canal vertébral du rachis. C'est une expansion de pie-mère reliant la face latérale de la moelle épinière à la dure-mère spinale, au niveau de son extrémité latérale. Le ligament dentelé se trouve donc dans l'espace sous-arachnoïdien. Il est dit dentelé car il est partiellement interrompu au niveau de la réunion des racines ventrale et dorsale de chaque métamère, latéralement à la moelle. (fr)

| - The denticulate ligaments, also known as dentate ligaments, are triangular shaped ligaments that anchor the spinal cord along its length, at each side, to the dura mater. The bases of the ligaments arise in the pia mater and they are firmly attached to the arachnoid mater and dura mater at the apex. They have 21 attachments per side. Their tooth-like appearance originates the word which derives from Latin denticulatus, from denticulus ‘small tooth’. The denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column. From a clinical standpoint, denticulate ligaments do not play a significant role in lumbar spinal stenosis when compared to issues such as disc herniations, facet hypertrophy, shape of spinal canal, size of spinal canal, ligamentum flavum hypertrophy, or degenerative joint disease resulting in bony osteophyte formation.
