What is ligamentum flavum hypertrophy?
The ligamentum flavum also hypertrophies, usually because of degenerative instability. That means it gets beat up by the extra movement between the vertebra caused by loose ligaments and disc collapse. Now ordinarily that wouldn’t be a problem but remember this ligament lives in the spinal canal and the spinal nerves run through that canal.
What is the equivalent of the ligamentum flavum?
Ligamentum flavum. The ligamentum flava are paired ligaments which run between adjacent laminae of the vertebral bodies and are present from C2/3 to the sacrum. Above the C2/3 level the equivalent structures are known as the posterior atlanto-occipital membrane (between the base of skull and C1) and the posterior atlantoaxial membrane (between...
What happens if the ligamentum flavum is damaged?
Poor posture, text neck, slip-disc in the neck, spondylosis, and subluxation damage to the ligamentum flavum lead to varying degrees of pain or symptoms. Cervical spine hypertrophy of the ligamentum flavum produces symptoms when the spinal cord or spinal nerves are pinched.
What does the yellow ligamentum flavum do?
Note that the yellow ligamentum flavum is on stretch when the low back is in flexion and thus allows the red spinal nerves lots of room. However, when the patient stands up straight or extends, note that the yellow ligamentum flavum now buckles into the spinal canal.
What does the ligamentum flavum prevent?
The ligamentum flavum is 80% elastic fibers and 20% collagen fibers. The elastic fibers within the ligamentum flavum prevent it from buckling into the intervertebral foramen (IVF) and vertebral canal, thus sparing the contents of these regions.

What does the ligamentum flavum connect?
One of a series of bands of elastic tissue that runs between the lamina from the axis to the sacrum, the ligamentum flavum connects the laminae and fuses with the facet joint capsules. These bands serve as a covering over the spinal canal.
In which region ligamentum flavum is strongest?
Ligamentum Flavum This yellow ligament is the strongest. It runs from the base of the skull to the pelvis, in front of and between the lamina, and protects the spinal cord and nerves.
What ligament prevents hyperflexion of the spine?
The supraspinous ligament is a cord-like band that runs along and connects the tips of the spinous processes from vertebra C7 to the sacrum. It is continuous superiorly with the nuchal ligament of the cervical region. This ligament prevents separation of spinous processes during flexion and resists hyperflexion.
Does ligamentum flavum thickening cause pain?
The buckling of LF (ligamentum flavum hypertrophy) is the main reason why many complain of increased pain during weight-bearing positions or when they extend the spine.
What causes ligamentum flavum thickening?
Ligamentum flavum can lose strength and elasticity, causing it to thicken and buckle towards the spinal column this is due to loss of elastic fibers which at same time increase in the thickness of collagen fibers ,These events cause deposition of Ca+2 in the ligament.
Where does ligamentum flavum attach?
The ligamentum flavum, the most elastic of the spinal ligaments, connects the laminae of one vertebra to the laminae of the vertebra below it, while laterally it forms the anterior capsule of the facet joint.
Is ligamentum flavum hypertrophy the same as spinal stenosis?
Ligamentum flavum (LF) hypertrophy is a common cause of lumbar spinal stenosis and is thought to be degeneration-driven. Developmental spinal stenosis (DSS) is characterized by pre-existing narrowed spinal canals and is likely a developmental problem that occurs in childhood.
What is severe ligamentum flavum hypertrophy?
Ligamentum flavum hypertrophy refers to abnormal thickening of the ligamentum flavum. If severe, it can be associated with spinal canal stenosis.
How do you treat ligamentum flavum thickening?
The current treatment approach for LF thickening includes operative and nonoperative treatment. Operative treatment includes such procedures as excision of the LF, decompressive laminectomy, and minimally invasive decompression.
What limits lateral flexion of the spine?
The intertransverse ligaments are located laterally. They limit lateral flexion to the opposite side of the body (contralateral lateral flexion) from where they are located.
Why is movement limited in the lumbar spine?
Because of the more sagittal slope of the articular surfaces, very little rotation takes place at the four upper lumbar levels. More distally, at the lumbosacral level, the joint line has a more coronal plane, which makes rotational movements potentially possible, but these are limited by the iliolumbar ligaments.
What ligament stops vertebra L5 from sliding forward on s1?
The iliolumbar ligament is composed of two bands, an anterior and a posterior band, both of which serve different functions. While its overall function is multifocal, the iliolumbar ligament, as a whole, is thought to be a ligament that prevents forward sliding of the L5 vertebrae onto the sacrum.
What is the function of the nuchal ligament?
The nuchal ligament limits forward flexion of the head and the cervical spine. It also serves as the attachment for some major muscles.
Why are there gaps at the midline of the ligamentum flavum?
There are gaps at the midline of the ligamentum flavum to allow the veins to exit.
What is the ligamenta flava?
9.5–9.7) are a series of ligaments that connect the lamina of adjacent vertebrae to form alternating sections of the posterior wall of the vertebral canal ( Bannister et al., 1996; Bogduk, 1997; Dickman et al., 1999; Moore et al., 2010). The LF are present bilaterally at each vertebral level, converging in the midline ( Bogduk, 1997; Moore et al., 2010 ). This ligament's perpendicular fibers attach to the anterior surface of the lower edge of the lamina above, as well as the inferior aspect of the pedicle, and proceed to descend down to the posterior surface of the upper edge of the lamina below ( Bannister et al., 1996; Bogduk, 1997; Dickman et al., 1999; Moore et al., 2010; Yong-Hing et al., 1976 ). As this ligament descends inferiorly, it divides into medial and lateral portions ( Bogduk, 1997 ). The medial portion passes to the back of the next lower lamina where it attaches to the rough area on the upper quarter of the dorsal surface of the lamina, and the lateral portion passes in front of the zygapophyseal joint formed by two vertebrae to which the ligament connects ( Bogduk, 1997 ). Inferiorly, the lateral portion of each ligament extends to the midpoint between two pedicles and forms the anterior capsule of the zygapophyseal joint, as it attaches to the anterior aspects of the inferior and superior articular processes of the zygapophyseal joint ( Bannister et al., 1996; Bogduk, 1997; Yong-Hing et al., 1976 ). In fact, the most lateral fibers extend along the root of the superior articular process as far as the next lower pedicle to which they are attached ( Bogduk, 1997 ). From where the posterior margins of the ligament meet as the ligament's attachments extend from the zygapophyseal capsule to where the laminae fuse to form spines, the ligament is only partially united, with intervals being left for veins connecting the internal to posterior external posterior vertebral venous plexus ( Bannister et al., 1996 ). Pintar et al. (1992) measured the lumbar LF in 22 cadaveric specimens and found that, on average, the LF measures 15.2 mm in length with a mean cross-sectional area of 84.2 mm 2. In the cervical region, the LF are thin and broad but thicken as they descend caudally, with the thickest ligaments found in the lumbar region ( Bannister et al., 1996; Moore et al., 2010 ). The average thickness of the LF, both at midline and laterally, was noted to be 2–3 mm by Yong-Hing et al. (1976). Recently, they concluded that the ligamentum flavum and interspinous ligaments (ISLs) in the lumbar region are confluent and are not two separate entities (Fig. 9.7) ( Iwanaga et al., 2019 ).
What is the interspinous ligament?
The interspinous ligaments are thin and almost membranous. They connect adjacent spinous processes, and their attachments extend from the root to the apex of each process, meeting the supraspinous ligament at the back and the ligamenta flava in front. In the cervical region they are only slightly developed as part of the ligamentum nuchae. 6 The interspinous ligaments add stability to the spine by checking excessive flexion. 6 Along with the supraspinous ligament the interspinous ligaments are typically the first structures to rupture in extreme flexion. 7
What are ligaments in the spinal cord?
The ligamenta flava are broad, paired ligaments that connect the spinal laminae. These ligaments arise from the ventral surface of the caudal lamina and attach to the dorsal border of the adjacent rostral lamina. Consequently, they are discontinuous at midvertebral levels and in the midline. They extend laterally to the joint capsules and become confluent. These ligaments extend from the C1-2 level to the L5-S1 level. They have a high elastin content and are yellow. In fact, the ligamenta flava are the most elastic tissues in the human body. The capsular ligaments attach the adjacent vertebra to the articular joints. The fibers are longer and more slack in the cervical than in the thoracic and lumbar levels of the spine. The fibers are perpendicular to the plane of the articular surfaces.
What is the gap between the ligamenta flava and the posterior external venous plexus?
Small gaps exist between the left and right ligamenta flava, allowing for the passage of veins that unite the posterior internal (epidural) vertebral venous plexus with the posterior external vertebral venous plexus. The ligamentum flavum between C1 and C2 is usually thin and membranous and is pierced by the C2 spinal nerve.
What is the homologue of the ligamenta flava?
The posterior atlanto-occipital membrane is the homologue of the ligamenta flava at the level of occiput-C1. Each ligamentum flavum is approximately 5 mm thick from anterior to posterior ( Panjabi et al., 1991 b).
What causes ligamenta flava hypertropy?
However, as described in Chapter 7, many instances of ligamenta flava hypertropy are probably the result of inflammation related to repeated microtears in the ligament. The inflammation then leads to hypertrophic scar formation (fibrosis) ( Sairyo et al., 2007 ).
What is the ligamenta flava?
The ligamenta flava (singular: ligamentum flavum) are paired ligaments which run between adjacent laminae of the vertebral bodies and are present from C2/3 to the sacrum. Above the C2/3 level, the equivalent structures are known as the posterior atlanto-occipital membrane between the skull base and C1 and between C1 and C2 may be known as ...
What does the Latin word "flavium" mean?
History and etymology. Flavum is Latin for yellow, referring to the color of the ligament. ligamentum flavum cysts. ossification of the ligamentum flavum. ligamentum flavum hypertrophy.
What is a paired, yellowish, elastic ligament?
paired, yellowish, elastic ligament. forms part of the posterior border of the spinal canal. relatively thin in the cervical spine, progressively becoming thickest in the lumbar spine. broad base along the lamina from the facet joints to base of the spinous process.
What Is Ligamentum Flavum?
It is an extremely elastic ligament, which connects the spinal bones through its two laminae, articular joints (facets and pedicles) attachment points on each side of the spine, from C2-S1. But, what makes it unique is the fact that it functions as a muscle as well. The muscular function of LF enables the spine to realign following forward bending motions.
What Is The Function or Purpose Of Ligamentum Flavum (LF)?
Elastin, which we will discuss in upcoming sections, provides ligamentum flavum (LF) significant elasticity. The elastic nature of LF is critical to the maintenance of an upright or a standing posture. LF is a ligament that functions much like a muscle. The muscular component allows it to have contractibility.
What Is Elastin? How It Impacts Ligaments In The Spine?
It enables our connective tissues to regain or “snap back” into position or their original shape after physical stress or stretch.
What Causes Ligamentum FLavum Hypertrophy?
The actual cause of LF hypertrophy is related to elastin fragmentation, collagen type IV deposition , and calcification of elastin and cartilage. In this section, we will discuss the stresses and activities that accelerate LF hypertrophy. Hypertrophy of ligamentum flavum is an age-related disorder in which there is a decrease in elastin-to-collagen ratios in ligamentum flavum. Although often seen in the elderly, it can happen at any age. The leading cause is neglect of minor injuries.
What Symptoms Are Present When Ligamentum Flavum Hypertrophy Is In The Neck?
Thickening of Ligamentum Flavum (LF) can occur at any point in the spine. We have already covered the most common site: the lower back. Now, let us look at the second most commonplace, or the neck, for ligamentum flavum hypertrophy. The neck is the second most common site for LF overgrowth, but it is critically dangerous.
How Effective Is Chiropractic Care For Ligamentum Flavum Thickening?
Chiropractic care is best for any type of spine, joint, and sports injuries. However, for you to benefit from chiropractic care, it must be targeted and condition-specific. Chiropractic is similar to other professions. It has those who are mediocre, average, above average, and best. Of course, getting treated by the best chiropractor will have greater benefits.
What are the factors that contribute to ligament flavum hypertrophy?
The combined impacts of elastin fragmentation, collagen deposition (collagen Type IV), and the eventual calcification of damaged elastin and collagens are the leading factors in developing ligament flavum hypertrophy.
What is ligamentum flavum?
The phrase ligamentum flavum means "yellow ligament". The ligamentum flavum is made of a (pale) yellow-colored elastic tissue. This tissue is similar to the type of connective tissue that comprises the other spinal ligaments, except there’s a degree of elasticity to it.
Where is the ligament flavum located?
It is located between the laminae of the vertebra. At each vertebral level, fibers originate from a superior lamina (the term superior refers to a location above, relatively speaking) and connect to the inferior lamina (i.e. the lamina just below). The ligamentum flavum limits spinal flexion (bending forward), especially abrupt flexion. This function enables the ligamentum flavum to protect your discs from injury.
What ligaments provide stability to the column?
Spinal ligaments also provide stability to the column. They do this by limiting the degree of movement in the direction opposite their location. For example, your anterior longitudinal ligament (see below for details) is located in front of your vertebral bodies. When you arch back, it prevents you from going too far.
What is the intertransverse ligament?
Intertransverse ligaments go from a superior (remember, superior refers to an above location, relatively speaking) transverse process of a vertebra to the transverse process of the vertebra below it . The intertransverse ligaments connect these processes together and help limit the action of side bending (lateral flexion). They also form a sort of border between the bodies in front and the bony rings in the back of the vertebrae.
Which ligaments are more fibrous?
In the thoracic (mid-back) area, the intertransverse ligaments are tougher and more fibrous. Now you know your ligament ABCs. These are the spinal ligaments that affect all or at least large portions of the spine. Other spinal ligaments are specific to an area such as the neck or the sacrum and sacroiliac joints.
Which ligaments limit forward bending?
The supraspinous and interspinous ligaments both limit flexion (forward bending). Located in back, the supraspinous ligament is a strong rope like tissue that connects the tips of the spinous processes from your sacrum up to C7 (otherwise known as the base of the neck).
Where is the nuchal ligament located?
Ligamentum Nuchae. Also known as the nuchal ligament, this ligament is located at the back of your neck. It merges with the supraspinous ligament, which as we’ve discussed, is that long, strong cord that connects the tips of most (i.e. the lumbar and thoracic) of your spinous processes.
What is a ligament?
Peer Reviewed. Ligaments are fibrous bands or sheets of connective tissue linking two or more bones, cartilages, or structures together. One or more ligaments provide stability to a joint during rest and movement. Excessive movements such as hyper–extension or hyper–flexion, may be restricted by ligaments.
Which ligaments prevent movement in certain directions?
Further, some ligaments prevent movement in certain directions. Three of the more important ligaments in the spine are the Ligamentum Flavum, Anterior Longitudinal Ligament and the Posterior Longitudinal Ligament . The Ligamentum Flavum forms a cover over the dura mater: a layer of tissue that protects the spinal cord.
What are the primary spinal ligaments?
Primary Spinal Ligaments Include: Limits…. 1. Supraspinous Ligament (flexion) 2. Ligamentum Nuchae (fibrous membrane) As mentioned in the Vertebral Column, the Atlas (C1) and Axis (C2) are different from the other spinal vertebrae.
Which ligament connects the facet joints to the posterior openings of the vertebrae?
The Ligamentum Flavum forms a cover over the dura mater: a layer of tissue that protects the spinal cord. This ligament connects under the facet joints to create a small curtain over the posterior openings between the vertebrae. The Anterior Longitudinal Ligament attaches to the front (anterior) of each vertebra.
Where is the anterior longitudinal ligament located?
The Anterior Longitudinal Ligament attaches to the front (anterior) of each vertebra. This ligament runs up and down the spine (vertical or longitudinal). The Posterior Longitudinal Ligament runs up and down behind (posterior) the spine and inside the spinal canal.
What are the two ligaments of the cervical spine?
Ligaments of the Back of the Cervical and Upper Thoracic Spine. 1. Supraspinous Ligament (flexion) 2. Ligamentum Nuchae (fibrous membrane) Ligament Systems – Atlas and Axis. As mentioned in the Vertebral Column, the Atlas (C1) and Axis (C2) are different from the other spinal vertebrae.
