What is decompression of thecal sac?

What is decompression of thecal sac?

What does decompression mean when performed in spinal surgery? Decompression is the release of pressure on a spinal nerve root or on the spinal cord itself. Decompression is necessary when patients develop radiculopathy and/or myelopathy due to spinal disease.

What does narrowing of the thecal sac mean?

Thecal Sac Compression – The spinal cord and nerves are also protected by a membrane filled with cerebral spinal fluid known as the thecal sac or dural sac. Flattening or compression of the thecal sac will occur in other conditions that cause pressure or pinching of the spinal cord, such as stenosis.

Where does the thecal sac begin?

It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra.

What does thecal sac mean?

Thecal sac is the outer covering of the spinal cord. This means there are bone spurs on the back of the spinal bones, putting pressure on or affecting the front part of the outer layer of the (neck) cervical spinal cord.

What is in the thecal sac?

The thecal sac, enclosing the spinal cord and cauda equina, sits within a protective ring of bone consisting of the vertebral body anteriorly, and the pedicles, lamina, and spinous process posteriorly. The epidural space contains fat and blood vessels, and lies between the spinal dura and the bony ring.

What activities should be avoided with spinal stenosis?

3 Spinal Stenosis Exercises To Avoid

• Avoid stretching in a standing position and extension stretches.
• Instead, try stretching while laying down.
• Avoid doing free weights.
• Instead, try using a weight machine.
• Avoid running and similar high-impact exercises.
• Instead, try swimming, cycling, or an elliptical machine.

What does thecal mean?

[ thē′kəl ] adj. Of or relating to a sheath, especially a tendon sheath.

What happens when the thecal sac is impinged?

Thecal sac impingement will often lead to painful conditions. The thecal sac is filled with CSF (cerebrospinal fluid), and it covers the spinal cord. Its parts are the inner dura and the outer arachnoid membrane. The thecal sac runs “until the S1 to S3 vertebral levels”. When the spine bends forward (flexes), it “elongates and moves upwards”.

What makes up the lining of the thecal sac?

The thecal sac is a covering of the spinal canal that is filled with cerebrospinal fluid (CSF). It houses the spinal cord and nerve roots. It is made up of outer arachnoid membrane and inner dura.

Where is the thecal sac in the spinal cord?

The thecal sac is the protective enclosing membrane which surrounds the spinal cord and cauda equina. This sac is filled with cerebral spinal fluid and is often featured prominently on MRI imaging reports for back pain patients. While most people are not sure exactly where this sac actually exists in…

What are the side effects of thecal sac?

Thecal Sac Purpose. Symptoms include chronic severe headaches and dizziness, among other concerns. Leaking spinal fluid is one of the many common complications of any invasive back pain treatment. In many instances, a secondary surgical procedure might be needed to seal off significant and unresponsive spinal fluid leaks.

What is the thecal sac and what does it do?

The thecal sac has a fluid in it and is a protective membrane which is covering the spinal cord and neurological structures within the body. It is basically the insulation for your nerve tissues and holds the spinal fluid as well.

What causes the compression of the thecal sac?

Spinal Canal Stenosis is another reason for the compression of the Thecal Sac. Injury or fracture of the Spinal Cord may also result in the compression of the Thecal Sac. Cysts can force the situation to be like this.

How does the thecal sac protect the spinal cord?

The thecal sac is simply a membrane which surrounds the spinal cord and spinal nerves. It is filled with cerebral spinal fluid and acts as a protective barrier for sensitive nerve tissue.
