Résumé :

Background and purpose: Long-term efficiency (> 5 years) of spinal cord stimulation for failed back surgery syndrome is poorly described in literature. The aims of our study were to evaluate the long-term efficiency and the quality of life of our series of patients with spinal cord stimulation for failed back surgery syndrome. Methods: The data of 55 patients implanted successively in our institution between 1995 and 2005 for failed back surgery syndrome were collected retrospectively. We contacted them for a telephone survey focused on efficiency, quality of life and treatment satisfaction. Results: An internal pulse generator was placed in 42 patients. Thirty-two of them were contacted to answer our survey with a mean follow-up of 8.3 years. Seventy-five percent of our population reported a pain decrease of greater or equal to 50%. The efficiency of percutaneous leads was reported as 50% for the quadripolars and 83% for the octopolars. The surgical leads evaluations were positive in 70% for 4 × 1 as well as for 4 × 2 leads. We observed a default of low back pain relief in 84% of patients with an incomplete pain relief (59%). The ability to sit, get out of the bed, and climb stairs increased in 75%. The walk was better in 82%. Decrease in drug consumption of greater or equal to 50% was observed in 66%. Conclusions: Our retrospective study demonstrates a satisfaction of 75% of the patients after 8.3-years follow-up. Spinal cord stimulation is an effective treatment for refractory failed back surgery syndrome. © 2011 Elsevier Masson SAS.
