[Sciatica caused by disk herniation in children. Apropos of 4 cases].

The authors report 4 cases of sciatica from disk herniation occurring in children under 16. It happens rarely in this age range, as is shown in the review of the literature performed for this article. The symptomatology is similar to that in adults. The physical signs are much more prominent than the functional signs. An original traumatism, sometimes severe, is often encountered. The standard X-ray examination is of little use in diagnosis, while contrast studies (opaque myelography, phlebography) clearly show the lesions of compression. Surgical treatment is frequent but not compulsory, following the same rules than in the adults. The post-operative results are usually excellent.
