The prevalence of a symptomatic herniated lumbar disc is about 1 to 3% in Finland and Italy, depending on age and sex. The highest prevalence is in persons 30 to 50 years of age, with a male-to-female ratio of 2:1. In persons 25 to 55 years of age, about 95% cases of herniated disc occur at the lower lumbar spine (L4–5 level); disc herniation above this level is more common in persons older than 55 years. [16]

Almost 5% of males and 2.5% of females experience sciatica at some time in their lifetime. [8]
