The supraspinous ligament, along with the posterior longitudinal ligament, interspinous ligaments and ligamentum flavum, help to limit
hyperflexion of the vertebral column
.
What movement does the interspinous ligament limit?
| Ligament Spinal Region Limits… | Interspinous Lumbar Flexion | Intertransverse Lumbar Lateral flexion |

What does the interspinous ligament do?
Function. The role of the interspinous ligament is
to limit flexion (bending forwards) through restricting separation of the spinous processes of the vertebral column
.
What is the difference between interspinous ligament and supraspinous ligament?
The supraspinous ligament in the thoracic region is a thin membranous structure. It’s only at the thoracolumbar junction does it become better defined. The interspinous ligaments run between,
to attach on to, consecutive spinous processes
.
What are the 3 more important ligaments of the spine?
Ligaments. The ligaments are strong fibrous bands that hold the vertebrae together, stabilize the spine, and protect the discs. The three major ligaments of the spine are
the ligamentum flavum, anterior longitudinal ligament (ALL), and posterior longitudinal ligament (PLL)
(Fig.
What muscles attach to the supraspinous ligament?
At the points of attachment to the tips of the spinous processes fibrocartilage is developed in the supraspinous ligament and it is intimately blended with the interspinal ligaments and neighbouring fascia.
The trapezius muscles
meet midline, merging with the supraspinous ligament from C7 to T12.
What causes your ligaments to thicken?
As we age, our ligaments may be subject to thickening, a condition called
hypertrophy
. Hypertrophy can cause symptoms such as nerve-related pain. Hypertrophy can develop further, into ossification, or hardening of the ligament(s).
What causes thickening of spinal ligaments?
As people age, the ligaments of the spine can thicken and harden (called
calcification
). Bones and joints may also enlarge, and bone spurs (called osteophytes) may form. Bulging or herniated discs are also common. Spondylolisthesis (the slipping of one vertebra onto another) also occurs and leads to compression.
Can you tear a ligament in your lower back?
Lumbar sprain
is caused when ligaments (the tough bands of tissue that hold bones together) are torn from their attachments. Both of these can result from a sudden injury or from gradual overuse. Lumbar strain or sprain can be debilitating.
Where are located interspinous ligaments?
Anatomical terminology
The interspinous ligaments (interspinal ligaments) are thin and membranous ligaments, that
connect adjoining spinous processes of the vertebra in the spine
. They extend from the root to the apex of each spinous process.
How long is the interspinous ligament?
The average of length A, length P, and length H was
11.56 ± 2.32 mm
(range, 6.40–18.70 mm), 12.01 ± 2.23 mm (range, 6.54–17.73 mm), and 21.42 ± 2.97 mm (range, 13.96–29.80 mm), respectively, on the left sides.
What function do ligaments serve?
A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves
to hold structures together and keep them stable
.
How long does it take to heal a torn ligament in the back?
Usually, ligament injuries occur from a traumatic event, and depending on the severity of the injury, they can take from
6 weeks to a full year
to heal.
What part of the spine controls the legs?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The
nerves of the lumbar spine
then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
How thick is the interspinous ligament?
The mean thicknesses presented as:
Upper (0.22 mm); Middle (0.37 mm) and L5-S1 (0.72 mm)
. Ligaments in the females were slightly thinner in comparison to the males. Fibres of inter-spinous ligaments were also found to attach to the inner aspects of the supraspinous ligament.
