Abnormal magnetic-resonance scans of the lumbar spine in asymptomatic subjects. A prospective investigation
TLDR
In this paper, the authors performed magnetic resonance imaging on sixty-seven individuals who had never had low-back pain, sciatica, or neurogenic claudication, and found that about one-third of the subjects were found to have a substantial abnormality.Abstract:
We performed magnetic resonance imaging on sixty-seven individuals who had never had low-back pain, sciatica, or neurogenic claudication. The scans were interpreted independently by three neuro-radiologists who had no knowledge about the presence or absence of clinical symptoms in the subjects. About one-third of the subjects were found to have a substantial abnormality. Of those who were less than sixty years old, 20 per cent had a herniated nucleus pulposus and one had spinal stenosis. In the group that was sixty years old or older, the findings were abnormal on about 57 per cent of the scans: 36 per cent of the subjects had a herniated nucleus pulposus and 21 per cent had spinal stenosis. There was degeneration or bulging of a disc at at least one lumbar level in 35 per cent of the subjects between twenty and thirty-nine years old and in all but one of the sixty to eighty-year-old subjects. In view of these findings in asymptomatic subjects, we concluded that abnormalities on magnetic resonance images must be strictly correlated with age and any clinical signs and symptoms before operative treatment is contemplated.read more

TL;DR: In this paper, the authors reviewed the potential risks and benefits of non-fusion technology in spine surgery and concluded that there is no evidence that nonfusion implants are superior to fusion in mid- to long-term follow-up.

TL;DR: Type I Modic changes in the lumbar region are significantly associated with LBP and profiling Modic change may be helpful to improve targeted treatment of LBP.

Specificity of needle electromyography for lumbar radiculopathy and plexopathy in 55-to 79-year-old asymptomatic subjects
TL;DR: Needle electromyography has excellent specificity for lumbosacral radiculopathy and plexopathy when appropriate diagnostic criteria are used.

Annulus cells from more degenerated human discs show modified gene expression in 3D culture compared with expression in cells from healthier discs
TL;DR: It is shown that annulus cells from more degenerated discs show modified gene expression in 3D culture, which has potential application in future cell-based biologic therapies for disc degeneration.

TL;DR: Imaging may be appropriate; however, it is not always indicated for evaluation of cervicogenic headache without neurologic deficit, and expert opinion may supplement the available evidence to recommend imaging or treatment.

A study of computer-assisted tomography. I. The incidence of positive CAT scans in an asymptomatic group of patients.
TL;DR: To study the type and number of CAT scan abnormalities of the lumbar spine that occur in asymptomatic people, 52 studies from a control population with no history of back trouble were mixed randomly with six scans from patients with surgically proven spinal disease, and all were interpreted by three neuroradiologists in a blinded fashion.

TL;DR: The incidence of myelographic abnormalities in 300 patients who were studied by posterior fossa myelography to establish a diagnosis of acoustic tumor is reported, even though patients had no symptoms of cervical or lumbar nerve root compression at the time of the examination.

The question of lumbar discography.
TL;DR: It has not been established whether internal derangement of the lumbar disc is sufficiently symptom-producing to be a therapeutic objective, especially a surgical one, or whether it represetits anything more than an aging process, and the patterns of degeneration seen in 628 of 2,187 discs injected by the Cleveland group and 773 of 6,784 discs injections by Feinberg or 322 of 870 disc injected by Massie and Stevens may represent nothing more than normal patterns for the age

TL;DR: The results of this study indicate that a technically adequate MR examination was equivalent to CT and myelography in the diagnosis of lumbar canal stenosis and herniated disk disease.
