Prevalence of lumbar disc degeneration observed by magnetic resonance in symptomless women.
302 women aged 16-80 without symptoms of spinal disease had their lumbar intervertebral discs examined by magnetic resonance. The prevalence of one or more degenerate discs increased linearly with age but disc degeneration was already present in over one-third of women aged 21-40; these young women may prove to be at special risk of disc prolapse later in life. The high prevalence of symptomless disc degeneration must be taken into account when magnetic resonance is used for assessment of spinal symptoms.
