What are the levels of cervical stenosis?

What are the levels of cervical stenosis?

Cervical canal stenosis was classified according to the T2-weighted sagittal images into the following grades: grade 0, absence of canal steno- sis; grade 1, subarachnoid space obliteration exceeding 50%; grade 2, spinal cord deformity; and grade 3, spinal cord signal change.

What is the normal AP diameter of the cervical spinal canal?

The anteroposterior (AP) diameter of the normal adult male cervical canal has a mean value of 17-18 mm at vertebral levels C3-5. The lower cervical canal measures 12-14 mm.

What is marked stenosis?

The lower row shows marked stenosis; the canal is narrowed and triangular in shape. The narrowing is often worse along the side edges and is called foraminal stenosis.

Is cervical stenosis progressive?

However, it is important to note that cervical stenosis does not always get worse and cause progressive symptoms. Many people have mild stenosis and never become symptomatic, or have mild symptoms which are not bothersome enough to seek treatment.

What is AP narrowing?

Absolute stenosis is defined as the anterior-posterior (AP) diameter of the spinal canal <10 mm. Relative stenosis: 10-12 mm AP diameter. • CT and MRI can visualize both the central and lateral canals.

What is the Torg ratio?

The relationship between the diameter of the spinal canal and the corresponding vertebral body. The Torg ratio is calculated through radiographical or MRI measurement by dividing the sagittal diameter of the canal by the diameter of the vertebral body.

How does cervical stenosis affect the spinal cord?

Definition. Cervical stenosis is a condition in which the spinal canal is too small for the spinal cord and nerve roots. This can cause damage to the spinal cord, a condition called myelopathy, or pinch nerves as they exit the spinal canal ( radiculopathy). Occasionally, damage to the spinal cord and nerve roots may occur,…

What are the treatment options for cervical stenosis?

Treatment Options for Cervical Spinal Stenosis. Most people with spinal stenosis do not need surgery. For many patients, non-surgical 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.

How old do you have to be to have cervical stenosis?

If cervical spinal stenosis causes spinal cord compression, your doctor may refer to the condition as cervical myelopathy. Most people who have cervical spinal stenosis are adults in their 50s and 60s who may have had neck pain for several years.

How can you tell if you have cervical stenosis?

Symptoms of cervical stenosis are related to abnormal compression of the spinal cord and nerve roots. Neck pain, pain in one or both arms, and an electrical sensation that shoots down the back when the head moves are common painful sensations in patients with spinal stenosis.
