What is thickening of the posterior longitudinal ligament?
Ossification of the posterior longitudinal ligament (OPLL) OPLL is a condition in which the flexible structure of the posterior longitudinal ligament becomes thicker and less flexible. It most commonly occurs in the cervical spine. OPLL typically presents with none or mild symptoms at the beginig.
What is posterior longitudinal ligament?
The posterior longitudinal ligament connects and stabilizes the bones of the spinal column. It runs almost the entire length of the spine, from the 2nd vertebra in the cervical spine (neck) all the way down to the sacrum (end of the spine). The ligament is adjacent to the spinal cord.
What does the posterior longitudinal ligament limit?
Posterior Atlantoaxial Ligament. Lateral Ligaments (2)…Primary Spinal Ligaments Include:
| Ligament | Spinal Region | Limits… |
|---|---|---|
| Posterior Longitudinal | Axis – Sacrum | Flexion & reinforces back of annulus fibrosis |
| Ligamentum Flavum | Axis – Sacrum | Flexion |
| Supraspinous | Thoracic & Lumbar | Flexion |
| Interspinous | Lumbar | Flexion |
What causes ossification of the posterior longitudinal ligament?
The exact cause of OPLL is unknown, but it typically occurs when the soft tissues on the spine calcify and narrow the spinal canal. This causes the compression on the nerves in the cervical spinal cord. Research has shown links to hereditary factors, the environment and an individual’s lifestyle.
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.
What is the function of the anterior longitudinal ligament?
The role of the ligaments is fundamental in determining the spine biomechanics in physiological and pathological conditions. The anterior longitudinal ligament (ALL) is fundamental in constraining motions especially in the sagittal plane. The ALL also confines the intervertebral discs, preventing herniation.
How do you treat thickened ligaments?
Treatment options for thickening ligaments
- Pressure and pain-relieving medications.
- Injections containing steroids and anesthetic to relieve inflammation and pain.
- Physical therapy.
- Surgical options.
Should I have surgery for cervical spinal stenosis?
Most people with spinal stenosis do not need surgery. For many patients, nonsurgical treatments—and there are many options—effectively reduce and manage pain and symptoms. Your doctor may recommend one therapy or combine it with different types of treatment.
