In the radiological examination of the spine one frequently sees in association with kyphoses very varied contours of the upper and lower vertebral margins. Mechanical Compression and Nucleus Pulposus Application on Dorsal Root the disc core is presumed to contribute to intervertebral disc hernia-related pain. This report examines 18 surgically proven L3/4 herniated nucleus pulposus ( HNP), all having myelogram, CT and adequate neurological evaluation. It will focus.

When a tear in the outer, fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings, the disc is said to be herniated. They can range from little or no pain, if the disc is the only tissue injured, to severe and unrelenting neck pain or low back pain that radiates into regions served by nerve roots which have been irritated or impinged by the herniated material.


Roxanne Mae Birador SN; 2. However, acute application of NP to a DRG without mechanical compression rapidly increases neuronal activity in the thalamus, a major brain relay nucleus processing information nuklus sensory pathways including ascending nociceptive tracts.

What is the abbreviation for Hernia Nukleus Pulposus?

The thalamus is the major brain relay nucleus for sensory information, including transmission in nociceptive pathways from the spinal cord en route to cortical regions where the information is processed further. There are a number of non-surgical methods used in attempts to relieve the condition.

For patients who underwent one level microendoscopic discectomy for lumbar disc herniation the Icing System CF can be used as it can be used to cool the spine when in ehrnia supine hernia nukleus pulposus or when lying hernia nukleus pulposus the hernia nukleus pulposus [81].


Spinal disc herniationalso known as a slipped discis a medical condition affecting the spine in which a tear in the outer, hernia nukleus pulposus ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings.

A recent study reported that NP applied to a DRG results in increased neuronal activity in the thalamus. The most conclusive diagnostic tool for disc herniation is MRIand treatment may range from painkillers to surgery. Annals of Internal Medicine. Am J Phys Med Rehabil.

Exercises that enhance back strength may also be used to prevent back injuries. Experimental set-up with stimulation and recording sites. Degenerated intervertebral disc prolapse and its association of collagen I alpha 1 Spl gene polymorphism: Surgery may be useful when a herniated disc is causing significant pain radiating into the leg, significant leg weakness, bladder problems, or loss of bowel control. BoxSE 30 Gothenburg, Sweden. Open in a separate window. It can also be torn, ripped, herniated, and degenerated, but it cannot “slip”.

A herniated disc in the lumbar spine may cause radiating nerve pain in the lower extremities or groin area and may sometimes be associated with bowel or bladder incontinence.

The inflammatory effect of nucleus pulposus. Classification of age-related changes in lumbar intervertebral discs: Light mechanical compression was induced by gently dislocating the L4 DRG with a G needle and was maintained by inserting the needle in the underlying bone, as previously described by Omarker and Myers. As a light mechanical compression may reduce transmission in nociceptive pathways it is possible that the presence or absence of NP is crucial for the development of pain development in the acute phase of disc herniation.

Song Z, et al.

Symptoms of a herniated disc can vary depending on the location of the herniation and the types of soft tissue involved. Nucleus pulposus is the inner core of the vertebral disc. Find articles by Katarina Rask. Back injuries are predominant in manual laborso the majority of low back pain prevention methods have been applied primarily toward biomechanics. The femoral nerve can also be affected and cause the patient to experience a numb, tingling feeling throughout one or both legs and even feet or a burning feeling in the hips and legs.


This study was supported by grants from the Dr. From Occiput to Coccyx”. The hydraulic effect hernia nukleus pulposus the contained, hydrated nucleus within the annulus acts as a shock absorber to cushion the spinal column from forces that are applied to the musculoskeletal system.

Narrowed space between L5 and S1 vertebrae, indicating probable prolapsed intervertebral disc – a classic picture. Pain medications may be prescribed to alleviate acute pain and allow the patient to begin exercising and stretching.
