[The post-diskotomy syndrome].

After lumbar disc operations in some cases epidural scars develop. The symptoms consist of back- and leg pain combined with a both sided straight leg raising test. In the myelogram and CT scars can be seen. The conservative therapy can be made by local injections with steroids. A lumbosacral distraction spondylodesis with autologous bone graft can bring a certain relief. Important is a prophylaxis with the right indication for the primary disc operation: without discectomy no post-discectomy-syndrome.
