What does HNP mean in medical terms?
Overview. Herniated nucleus pulposus is a condition in which part or all of the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of the disk, resulting in back pain and nerve root irritation.
What is MRI HNP?
The acute lumbar herniated nucleus pulposus (HNP) can often be diagnosed on good quality MRI or CT examination.
What is focal HNP?
Focal herniation involves less than 25% of the disc circumference, whereas broad-based herniations involves between 25-50% of the disc circumference. Herniation rarely results from a single traumatic incident. Acute traumatic cervical HNP serves as a major etiology of central cord syndrome.
What is a cervical HNP?
Herniation of the nucleus pulposus (HNP) at the cervical level often results in radiculopathy, marked by compression and inflammation of the cervical nerve root near the neural foramen. Cervical HNP can be generally classified into four types: disc bulge, protrusion, extrusion, and sequestration [1].
What is HNP C5 C6?
C5-C6 Disc Herniation. Home > Conditions We Treat > Herniated Disc > C5-C6 Disc Herniation. A herniated disc in the c5-c6 level of the spine can cause weakness in the biceps muscles of the arms and wrist extensor muscles as well as numbness and tingling along with pain that radiates to the thumb and fingertips.
How is HNP diagnosed?
The accuracy of computed tomography (CT), myelography, CT-myelography (myelo-CT) and magnetic resonance imaging (MRI) for the diagnosis of lumbar herniated nucleus pulposus (HNP) is compared prospectively in 59 patients, all of whom underwent surgical exploration.
What is a myelogram of the spine?
A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography (CT) to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.
What is HNP stenosis?
Spinal HNP: Herniated Nucleus Pulposus (HNP) is a lumbar spine condition in which one or more discs in your spine dislocate or compress due to pressure from the surrounding vertebrae.
