The transverse ligament of the atlas (TLA) is a thick, strong band of approximately 20mm in length which arches across the ring of the atlas and maintains the odontoid process in contact with the anterior arch. It is concave in front, convex behind and broader at the middle than at the ends.

In anatomy, the transverse ligament of the atlas is a broad, tough ligament which arches across the ring of the atlas (first cervical vertebra) posterior to the dens [1] to keep the dens (odontoid process) in contact with the atlas.

2024年10月27日 · Atlas fractures and transverse ligament injuries are traumatic injuries usually caused by high-energy trauma with axial loading in young patients (Jefferson fracture) or low-energy falls in the elderly.

2023年12月6日 · The transverse ligament holds the dens of the axis against the anterior arch of the atlas and divides its vertebral canal into two parts. The anterior 1/3 is occupied by the dens. The posterior 2/3 contains the spinal cord, which occupies 1/3 of the total vertebral canal space.

2023年10月30日 · Transverse ligament of atlas: the transverse ligament of atlas is a strong, broad ligament that runs transversely between the lateral masses of the atlas, attaching to tubercles on their medial aspects.

The transverse ligament of the atlas is a strong horizontal band that extends across the atlantal ring between its two lateral masses. Its anterior aspect is in contact with the posterior aspect of the dens. Together with the longitudinal bands, it forms the cruciate ligament of the atlas.

The transverse ligament is the strongest and thickest ligament of the CCJ, which runs around the dens’ posterior aspect and attaches to the atlas’s lateral tubercles. 1 One of its key functions is to maintain the CCJ’s stability by locking the dens anteriorly, restricting posterior movement within the atlas, and inhibiting pathological ...

2013年4月4日 · Both the transverse ligament of the atlas and the alar ligaments are located within the spinal canal (canalis vertebrali s). The ligaments are clearly distinguishable and visible as stiff structures having a silvery hue (Figure 1). Craniocervical junction in a silver fox. Dorsal view of atlantooccipital and atlantoaxial joints.

thick, strong, centrally flattened band spanning the vertebral foramen of the atlas as it extends from the medial aspect of one lateral mass to the other, passing dorsal to the dens with which it articulates; it forms the dorsal portion of the opening for the dens, tightly embracing its neck.

Objective: This study seek to establish the prevalence of calcification of the transverse ligament of the atlas (TLA) and of crowned dens syndrome (CDS) in patients with articular chondrocalcinosis. It also seeks to assess the main computed tomography appearances of these calcifications.

One of the most crucial ligaments in the body, the transverse ligament of the atlas is a critical part of the cruciform ligament. Its usual height/thickness is 6–7 mm, making it the largest, strongest, and thickest craniocervical ligament. The transverse ligament maintains stability at the CCJ by locking the odontoid process anteriorly ...

2013年10月1日 · In order to diagnosis a transverse ligament rupture in the cervical spine, clinicians normally measure the atlas–dens interval by using CT scan images. However, the impact of this tear on the head and neck complex biomechanics is not widely studied.

Tears of the transverse ligament of the atlas. A clinical and biomechanical study J Bone Joint Surg Am. 1974 Dec;56(8):1683-91. Authors J W Fielding, G van B Cochran, J F Lawsing 3rd, M Hohl. PMID: 4434037 No abstract available. MeSH terms Adolescent Adult ...

Transverse ligament of the atlas: what is it? Le ligament transverse de l ' atlas is a ligament essential to support the weight of the head on the spine. This fibrous and strong band crosses the ring of the atlas and attaches to the odontoid process.

The transverse ligament of the atlas is a thick, strong band, which arches across the ring of the atlas, and retains the odontoid process in contact with the anterior arch. It is concave in front, convex behind, broader and thicker in the middle than at the ends, and firmly attached on either side to a small tubercle on the medial surface of ...

The second is the transverse ligament of the atlas, locking the dens axis against the anterior arch of C1. Together with the thin longitudinal fascicles, the transverse ligament forms the cruciform ligament of the atlas. Click an image to remove the cruciform ligament and see the dorsal surface of the dens axis covered with the cartilage.

2018年12月15日 · Objective: The aim of this study was to assess the prevalence and natural course of calcification of the transverse ligament of the atlas (TLA) in healthy subjects and to investigate the relationship between the calcified lesion and clinical factors.

Just below the medial margin of each superior facet is a small tubercle, for the attachment of the transverse atlantal ligament which stretches across the ring of the atlas and divides the vertebral foramen into two unequal parts: ... Accessory transverse foramen of the atlas is present in 1.4–12.5% across the population. [7]

2023年10月30日 · Similar to most typical joints, the vertebral column is associated with various ligaments. These ligaments serve to strengthen and stabilize the articulating bones and structures that form the joints of the vertebrae, as well as resist …

The transverse ligament arises from the tubercle on the atlas (C1) and holds the chondral surface of the odontoid process firmly against the anterior arch. The transverse ligament is the primary stabilizer that prevents abnormal anterior translation of C1 on C2 (Yoganandan et al., 2001).
