Der Schmerz
-
In Western industrial countries, low back pain is one of the most frequent causes of illness. Between the 4th and 5th decades of life approximately 80% of adults complain of low back pain, lasting for fairly long periods. About 10% of this population must undergo disc surgery once during life. ⋯ CT control examinations showed clear regression in the extent of disc herniation in 15 patients, in 18 a moderate decrease, and in 9 cases the CT findings had not changed. A favorable tendency towards regression was observed in disc herniations at the level of L5-S1 and in cases showing sequestration of the disc. Herniations of the disc at higher levels between L4-5 and L3-4 or a lateral herniation, reaching the intervertebral foramen, showed on unfavorable prognosis.
