What does central canal stenosis ap diameter is 9mm mean?
Central canal stenosis with an anterior-posterior (AP) diameter of 9mm indicates a narrowing of the central spinal canal, which is the space within the spine that houses the spinal cord and nerve roots. An AP diameter of 9mm is generally considered to be below the normal range, potentially leading to compression of the spinal cord or nerves. This condition can result in symptoms such as pain, numbness, or weakness in the extremities, depending on the severity and location of the stenosis. Evaluation by a healthcare professional is recommended for appropriate management.
What is the normal AP diameter of of the central cervical canal?
11-16mm
What spinal canal diameter is a spinal stenosis indicator?
The spinal canal is usually more than 0.5 in (12 mm) in diameter. A smaller diameter indicates stenosis. The diameter of the cervical spine ranges is 0.6-1 in (15-12 mm). Any opening under 0.5 in (13 mm)in diameter is considered evidence of stenosis.
What diameter is the central canal?
The diameter of the central canal in the spinal cord typically ranges from 0.5 to 1 millimeter, although this can vary among individuals. The canal is a narrow, fluid-filled space that runs longitudinally through the center of the spinal cord and contains cerebrospinal fluid. Its primary function is to protect and nourish the spinal cord while allowing for the circulation of this fluid.
What does AP mean in AP diameter?
The abbreviation "AP" in the phrase "AP diameter" means from front to back.
What is the normal diameter of the spinal canal?
The normal diameter of the spinal canal varies by region but generally ranges from about 13 to 15 millimeters in the cervical spine, 15 to 25 millimeters in the thoracic spine, and about 25 to 30 millimeters in the lumbar spine. A diameter of less than 10 millimeters in any region may indicate spinal stenosis, which can lead to neurological symptoms. Variations can occur based on individual anatomy and age.
What is meant by moderate ap thecal sac stenosis of 6.4 mm?
It means moderate spinal stenosis. Spinal stenosis (or narrowing) is a common condition that occurs when the small spinal canal, which contains the spinal cord, becomes compressed. This causes a 'pinching' of the spinal cord and/or nerve roots, which leads to pain, cramping, weakness or numbness.
Through what part of a vertebra does the spinal cord pass?
The central canal of the spinal cord. The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord.
Where is the spinal found?
in the spinal canal between the vertebrae.
What does spinal canal is patent?
When the spinal canal is described as "patent," it means that the canal is open and unobstructed, allowing for the normal passage of spinal nerves and cerebrospinal fluid. This indicates that there are no significant blockages or narrowing (stenosis) that could compress the spinal cord or nerves. A patent spinal canal is essential for maintaining proper neurological function and overall spinal health.
Right sub articular zone of spinal canal?
what is narrowing of the right subarticular zone of the spinal canal
What is normal cervical AP dimension?
The normal cervical anteroposterior (AP) dimension can vary depending on the specific level of the cervical spine being measured, but generally, the AP diameter of the cervical canal is around 10 to 14 millimeters in adults. A dimension less than 10 millimeters may indicate potential spinal stenosis, which could lead to neurological issues. It's important to evaluate these measurements in the context of individual anatomy and any existing clinical symptoms.
