How often does HNP occur in lumbar radicular pain?

What are the symptoms of a lumbar herniated disc?

Is the natural history of lumbar radicular pain favorable?
The natural history of radicular pain from HNP is favorable with similar outcomes in surgically and nonsurgically treated patients at 10-yr follow-up ( 39 ). The lifetime incidence of lumbar radicular pain from HNP is 13%-40%, with an annual incidence of 1%-5%, peaking in the fourth to fifth decades and declining thereafter ( 19 ).
When does HNP occur in the lumbar region?
Approximately 80% of HNPs occur in the lumbar region. The age-incidence curve for lumbar HNP peaks in the second through fourth decades of life and the incidence is higher in males than females. Other pathologic lesions (i.e. spondylosis and spinal stenosis) have been noted in 50% of the cases with lumbar HNP.
Which is the best diagnosis for lumbar herniated nucleus pulposus?

How is the HNP confirmed in a herniated disc?
HNP is confirmed by the demonstration of herniation of disc material (size and direction) and distortion/displacement of the thecal sac, epidural fat, and/or nerve root. However, repeated studies have failed to delineate a direct relationship between the degree of herniation and the amount of symptoms.
