The tectorial membrane is the rostral continu-ation of the posterior longitudinal ligament. Am Fam Physician. CT and MR imaging studies should always include this region when the mechanism of trauma is suggestive of craniocervical junction injury. It joins the axis body to the clivus on the anterior half of the foramen magnum, and ascends as high as the spheno-occipital synchondrosis and laterally extends to the hypoglossal canal. Continuation of the Posterior Longitudinal ligament. The ligament is more narrow at the vertebral bodies and wider at the intervertebral disc space which is more pronounced than the anterior longitudinal ligament. DDC klassifikationskod (Dewey Decimal Classification) The ALL and PLL have similar tensile properties (Przybylski et al., 1996). ... cartilage of the vertebral end plates, and the margins of the vertebrae. Limits flexion of the vertebral column and reinforces the intervertebral disc[1]. Tectorial membrane connects which structures? Car or sports accidents along with falls are the leading cause of injuries or trauma to the ligaments of the spine. D: Tectorial membrane of atlanto-axial joint It is a broad, strong band which covers the dens of the axis, and its ligaments, and appears to be a prolongation upward of the posterior longitudinal ligament of the vertebral column. Tectorial Membrane of Atlanto Axial Joint This is situated within the vertebral canal. The twin alar ligaments attach from the lateral aspect of the odontoid process (dens of C2) to the medial occipital condyles on either side. Spinal cord. Churchill Livingstone, ed. Here’s the cruciform ligament consisting of the transverse ligament of the atlas, the superior band, and the inferior band, and here are the two alar ligaments. 2010 Jan 1;81(1):33-40. Pain and dysesthesia in patients with spinal cord injury: a postal survey. The posterior longitudinal ligament is situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebrae, from the body of the axis, where it is continuous with the tectorial membrane of atlanto-axial joint, to the sacrum. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). Titel och upphov : Atlas of craniocervical junction and cervical spine surgery ; Utgivning, distribution etc. MR imaging is more sensitive than CT and allows thorough evaluation of craniocervical junction ligaments in better detail. It is a thick ligamentous broad band that extends from the body of C2 to the occipital bone at the ante-rior margin of the foramen magnum. 1/5/2015 6 ... test for tectorial membrane using MRI on 16 normal volunteers. With the head and neck in neutral position, the clinician gently distracts the head. What Causes Ligament Injuries? The TM is a 1 mm thick, superiorly directed extension of the posterior longitudinal ligament (PLL) located ventral to the spinal cord. The radiologist should be aware of these kinds of injuries in the pediatric population. Forming the anterior wall of the vertebral canal, this strong ligament spans from the body of the Axis (C2) to the posterior surface of the sacrum. Cruciform Ligament. As it enters the cranial cavity it becomes continuous with the dura mater. The Posterior Longitudinal Ligament extends up and down behind the spine and inside the spinal canal. When refering to evidence in academic writing, you should always try to reference the primary (original) source. To get a different view of it we’ll look at a specimen that’s been divided in the mid-line. PCovers the dens and its ligaments, goes up to the basilar grove of occipital bone. Tectorial membrane injuries and REH are typically seen in young children who sustain a high-speed head and neck injury.

Also near this cephalic bony attachment, there is an increase in the number of elastic fibers, which is found running parallel with the surrounding Type III collagen fibers. This ligament is composed of smooth, shining, longitudinal fibers, denser and more compact than those of the anterior ligament, and consists of superficial layers occupying the interval between three or four vertebrae, and deeper layers which extend between adjacent vertebrae. The major subaxial ligaments include the anterior and posterior longitudinal ligaments and the posterior … Posterior longitudinal ligament. From posterior side of C2 body to anterior edge of foramen magnum - continuous with posterior longitudinal ligament. ... Like its anterior counterpart the anterior longitudinal ligament, its deep fibers are intersegmental while the more superficial fibers can span up to four vertebral levels. Contributes to the stability of the upper cervical spine. It is a broad, strong band which covers the dens and its ligaments, and appears to be a prolongation upward of the posterior longitudinal ligament of the vertebral column. Flexion of the head makes the tectorial membrane fully taut at 15 degrees and extension makes it fully taut at 20 degrees; however, there occurs a buckling effect (redundant tectorial membrane) noted at the level of the odontoid process in extension. Continuous with the Posterior longitudinal ligament and found on the internal surface of the vertebral canal. It’s much broader and thicker here in the neck, than it is lower down the spine. With the alar and transverse ligaments cut and with flexion of the head, the middle portion of this membrane stretched over the odontoid process, thus acting as a "hammock" that inhibited the odontoid process from moving posteriorly. 1173185.

Arising at the superior margin of one vertebra they span to the inferior margin of the vertebra that they attach to.Forming the anterior wall of the vertebral canal, this strong ligament arises from the body of the axis (C2) body and travels downward and posterior to the vertebral bodies (attached loosely) and intervertebral discs (firmly attaching to the posterior annulus), attaching to the back of the sacrum. In most cases Physiopedia articles are a secondary source and so should not be used as references. OPLL can also cause dysesthesia, an unpleasant sensation that accompanies touch[5]. Like its anterior counterpart, the Anterior longitudinal ligament, its deep fibres are intersegmental while the more superficial fibres can span up to four vertebral levels. Histologically, parallel collagen fibers with spindle-shaped fibrocytes are observed within this membrane and near its attachment to the posterior axis, the collagen fibers are noted to be more homogenous with larger non-spindled fibrocytes. Tectorial membrane of cervical vertebral column: represents the superior continuation of the posterior longitudinal ligament. When refering to evidence in academic writing, you should always try to reference the primary (original) source. The posterior longitudinal ligament extends from the tectorial membrane of the basion to the posterior surface of each vertebra and disc, down to the coccyx. It is broader above than below, and thicker in the thoracic than in the cervical and lumbar regions. This is the posterior longitudinal ligament. Reproduction of symptoms suggests upper cervical ligamentous instability,particularly implicating the tectorial membrane.

Anteriorly lies the cruciform ligament. Forming the anterior wall of the vertebral canal, this strong ligament spans from the body of the Axis (C2) to the posterior surface of the sacrum. It is sandwiched between the alar ligaments and the cruciate ligament complex. The mean thickness of this membrane is about 1 mm. The tectorial membrane is found to be attached much more superiorly than previously described. Finnerup NB, Johannesen IL, Sindrup SH, Bach FW, Jensen TS. At the cranial attachment of the tectorial membrane, multiple calcified areas are noted that interdigitated with the underlying bone. The normal tectorial membrane and transverse ligament are routinely seen on MR imaging, whereas the normal alar ligaments can be more difficult to visualize because of … It runs posterior to the odon- That is usually the journal article where the information was first stated. The ligament is composed of longitudinal fibers that are denser than the anterior longitudinal ligament. Crossing ligament - transverse connects lateral tubercles of atlas - superior longitudinal connects posterior dens to anterior edge of foramen magnum - inferior longitudinal spans down to posterior side of C2 body.

Superiorly - body of C2, continuous with tectorial membrane Inferiorly - posterior surface of sacrum All the way down - attaches only to discs and adjacent area of vertebrae - separated by body by interval (basivertebral vein) Function - resists flexion of spine. The tectorial membrane does not limit cervical flexion per se but rather help to insure that the odontoid process does not impinge into the cervical canal. It serves as the posterior border of the supraodontoid space or apical cave (11). Mild symptoms may include; mild pain, tingling, and/or numbness in the hands. Ehara S, Shimamura T, Nakamura R, Yamazaki K. Paravertebral ligamentous ossification: DISH, OPLL and OLF. Symptoms of cervical radiculopathy include pain, tingling, or numbness in the neck, shoulder, arm, or hand[7]. Its anterior surface is in relation with the Transverse ligament of the atlas and its posterior surface with the dura mater. In the situation of the intervertebral fibrocartilages and contiguous margins of the vertebrae, where the ligament is more intimately adherent, it is broad, and in the thoracic and lumbar regions presents a series of dentations with intervening concave margins; but it is narrow and thick over the centers of the bodies, from which it is separated by the basivertebral veins. Tectorial Membrane. It runs along the posterior aspect of the vertebral body inside the vertebral canal from the body of the axis to the sacrum. Eubanks JD. The higher mobility of the pediatric craniocervical junction compared with that in adult patients is believed to facilitate craniocervical junction injuries. 1/5/2015 10 Sharp-Purser test for instability • Patient seated –head positioned in a … Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). The posterior longitudinal ligament runs in the spinal canal attaching to the vertebral bodies and vertebral discs and tightens with cervical flexion.

Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. 2001 May 1;39(5):256. In the cervical and thoracic regions it has a uniform width over the bodies and discs, but in the lumbar region the ligament is widest at the levels of the intervertebral discs where it is firmly anchored to the Annulus fibrosus, cartilage of the Vertebral end plates, and the margins of the vertebrae. Panjabi, J.J. Crisco, H.U. It serves as the posterior border of the supraodontoid space or apical cave (11). Strong broad structure which covers the Odontoid process and it's ligaments. It most commonly occurs in the cervical spine[4]. In most cases Physiopedia articles are a secondary source and so should not be used as references. The ligament is thicker in the thoracic than in the cervical and lumbar regions. Math. European journal of radiology. Arts and Humanities. Clinical symptoms may be minimal or misleading. These are the tectorial membrane (Fig. Languages. D: Tectorial membrane of atlanto-axial joint. The alar ligaments are also deep to the tectorial membrane. What is the tectorial membrane? The tectorial membrane, transverse ligament, and alar ligaments play an important role in stabilizing the craniocervical junction. Sagittal soft-tissue and bone algorithm reconstructions are helpful to identify these lesions on CT studies. The posterior longitudinal ligament (PLL) is a long and important ligament located immediately posterior to the vertebral bodies (to which it attaches loosely) and intervertebral discs (to which it is firmly attached). It is a broad, strong band which covers the dens of the axis, and its ligaments, and appears to be a prolongation upward of the posterior longitudinal ligament of the vertebral column . Strong broad structure which covers the Odontoid process and it's ligaments. 2005 Dec 1;18(6):492-7.

It narrows as it travels downward and also has a serrated edge[3]. Diagnosis is often made by findings on X-ray, CT and MRI imagining. The highest part of this ligament goes by a different name - it’s called the tectorial membrane. If the ligament takes up valuable space within the spinal canal as it thickens, it may compress the spinal cord, producing myelopathy, with symptoms that include difficulty walking and difficulty with bowel and bladder control[6]. Lateral flexion is not found to be limited by this structure. Ossification of the posterior longitudinal ligament (OPLL). The tectorial membrane is the thin superior continuation of the posterior longitudinal ligament from the body of the axis. It courses from the posterior aspect of the body of C2, inferiorly to the sacrum, and possibly to the coccyx (Behrsin & Briggs, 1988). The posterior longitudinal ligament is one of the three more important ligaments that contribute to stability in the spine. Posterior surface of the axis body and the basilar groove of the occipital bone. Ossification of the posterior longitudinal ligament (OPLL) is commonly seen in oriental populations, and its cause remains obscure. 1991 Nov 1;16(11):1277-82.
