The ligamenta flava (sg.: ligamentum flavum, Latin for yellow ligament) are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae. They help to preserve upright posture, preventing hyperflexion, and ensuring that the vertebral column straightens after flexion. Hypertrophy can cause spinal stenosis.
Ligamentous laxity, or ligament laxity, is a cause of chronic body pain characterized by loose ligaments. When this condition affects joints in the entire body, it is called generalized joint hypermobility , which occurs in about ten percent of the population, and may be genetic .
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.

Weakened ligaments and muscles contribute to poor posture, which may contribute to other medical conditions. Isometric exercise avoids hyperextension and contributes to strength. Unwanted symptoms are frequently reduced by some forms of yoga; Low-impact sports Use of low impact elliptical trainer machines can replace high-impact running.
Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. [1] It is distinguished from hyperplasia , in which the cells remain approximately the same size but increase in number. [ 2 ]
Spinal ligaments can thicken (ligamenta flava) [24] [25] Bone spurs develop on the bone and into the spinal canal or foraminal openings; Intervertebral discs may bulge or herniate into the canal or foraminal openings [26] Degenerative disc disease causes narrowing of the spaces. [27] Facet joints break down; Facet joints may hypertrophy [28]
In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the posterior longitudinal ligament, which may lead to partial or complete fusion of adjacent vertebrae. The facet and sacroiliac joints tend to be uninvolved. The thoracic spine is the most common level involved. [2]
The anterior ligament is not much of a ligament at all and in most cases is just a slight thickening of the anterior joint capsule. The anterior ligament is thin and not as well defined as the posterior sacroiliac ligaments. The posterior sacroiliac (SI) ligaments can be further divided into short (intrinsic) and long (extrinsic). [9]
