Longterm results of epidural electrical stimulation on a group of 80 cases of spinal arachnoiditis are analyzed. The follow-up varies between 2 and 4 years. The influence of socio-economic factors in the outcome of treatment are analyzed.
SPINAL CORD STIMULATION Ii; PATIENTS WITH A BATTERED ROOT SYNDROME. H.U. Gerbershagen, H.Waisbrod, Pain Center Mains, Auf der Steig 14-16, D-6500 Mainz, FRG Ten out of sixty-two consecutive cases of failed back surgery patients were diagnosed as Battered Root Syndromes. The criteria were: I) Multiple operated lumbar spine, 2) Constant and intractable radicular pain, 3) Amputated root on myelogram, 4) Periradicular scar tissue without spinal nerve canal stenosis in the C.T. picture, 5) Positive electrophysiological tests (E.M.G., S.S.E.P.], 6) Complete pain relieve by Xray-controlled root block. Based on the assumption that these roots present demyelinated areas that favoured ectopic spiking, we performed in each a proximally located spinal cord stimulation. There were 8 men and 2 women, the youngest 41 and the oldest 63. They were operated on their spine between 2 and 6 times before they were referred to us. They all had one root involved and could be rendered completely painfree by a single radicular block with Iml of bupivacaine. The L5 root was involved in 8 cases and the Sl in 2. We used the PISCES (Medtronic) system. The electrode tips did lie between D8 and D9, both on the affected side. If pain was relieved constantly during stimulation, the receiver was implanted on the tenth day. Up to now, with a short follow-up between six and thirty months all ten patients are still pain free. In spite of the short follow-up, it seems that with selected cases of a single battered root in multioperated-backs in whom no causal therapy can be anymore performed, S.C.S. affords good results.
