title: [Clinical evaluation of lumbar disc hernia in the teenagers].
abstract: Lumbar disc herniation is a rare occurrence in teenagers. There are several questions as to its pathogenesis, relationship to trauma, and clinical manifestations compared with those in adults. In the present paper, we described nine cases of teen-age lumbar disc herniation, which accounts for about 3.3% of all the operated lumbar disc herniations in our clinic. In the discussion, 687 cases of teen-age lumbar disc herniation were analyzed from the world literature. The clinical signs and symptoms in teenagers showed no distinct difference from those in adults. Laségue's sign was found in nearly all the patients. Although direct or indirect trauma to the lumbar region may play an important role in causing disc herniation in teenagers, a more important factor seems to be the degeneration of the disc material, which begins in children earlier than usually suspected. Although surgical therapy has been advocated by many authors, it must be followed up for a long term before the efficacy of such treatment for teenagers can be confidently ascertained.
