[Comparison of myelographic and operative findings in lumbar disk lesions (author's transl)]

A comparative study has been made of the myelographic, clinical and operative findings in 140 patients with lumbar disk lesions. The myelographic and operative findings corresponded in 95%. The L 4-5 disk was the most frequently affected. With regard to the operation, some of the most important technical points are discussed. A myelography is strongly recommended before every disk operation.
