[Indication for surgery in lumbar disk displacement].

After the description of the operative risk and the results of the operation in the lumbar dislocation of the disk the indications for an operation are demonstrated. According to our experiences the indication for the operation of disks may be a necessity in a part of patients, in order to avert remaining lesions. In a second group the operation should be carried out, since conservative measures cannot bring about a change of the complex of complaints and, apart from this, may be dangerous for the patient. In the third group the operation can be indicated, as after conservative treatment recidivations may appear again and again. The contraindications are described in short and our indication for lumbar myelography is demonstrated.
