In the paper we present a case of a long-segment string of bead-like intradural extramedullary schwannoma of cauda equina from L2 to S2.The patient had been suffering progressive low back pain and sciatica with progressive...

Our aim was to analyse causes for persistence of pain after lumbar discectomy and outcome of reoperations. Out of 37 reoperated patients, 22 with a minimum follow-up period of one year were included in this retrospective study concerning the years 1993 to 2000. All patients had previously undergone laminotomy and discectomy and fusion was not required during second operations. Outcome was evalu...

Our aim was to clarify this relationship. A total of 501 patients with lumbar degenerative disease and nerve-root symptoms was studied in respect of their level and the presence of TV. As a control group, 5...
