They are anatomically located in the space between the theca and the periosteum - known as the extradural neural axis compartment. (However, the good news here is that bladder and bowel function often improve in the years following surgery; it just may take longer to regain function than other affected areas.). An extension of the brain, the nerve roots send and receive messages to and from the pelvic organs and lower limbs. If radiculopathy is present and a herniated disc is suspected, MRI should be obtained if the patient fails to improve clinically. Some examinations might profit from the improved spatial and contrast resolution of 3 tesla.

Radiographic evidence of degenerative change is most common in patients older than 40 years and is present in more than 70 percent of patients older than 70 years.9 Degenerative changes have been reported to be equally present in asymptomatic and symptomatic persons.9 The incidence of intervertebral narrowing and irregular ossification of the vertebral end plates has also been shown to be associated with increased age.10 Even though plain radiographs usually provide little definitive information, they should be included in the screening examination for patients with certain red flags (Table 1).8. It should be used only to confirm an initial diagnosis, not as the primary diagnostic tool. Although leg pain is common and usually goes away without surgery, cauda equina syndrome, a rare disorder affecting the bundle of nerve roots (cauda equina) at the lower (lumbar) end of the spinal cord, is a surgical emergency.
