Ethanol Gel Versus Steroid in Refractory Lumbar Discogenic Pain

DISCOGEL® is on the market since 2007. About 20,000 kits were sold to date (October 2017). The device re-obtained its CE mark in 2017. A clinical evaluation was performed by bibliographic route in 2016. Clinical data on more than 600 patients treated by DISCOGEL® were analyzed. These data should be confirmed by monitoring on the long term, with a large cohort of patients, over a two-year follow-up period. As part of the post-CE surveillance, the manufacturer GELSCOM is responsible of this "Post-Market Clinical Follow-up" (PMCF) study in accordance with Directive 93/42/EEC and MEDDEV guide 2.12/2, to assess the efficacy and the long-term safety of DISCOGEL®. The study is comparative. The results will evaluate the performance and safety of the CE-marked medical device used in "real life", in comparison with a steroid infiltration, used according to its indication and to the current standards. It will include economic data. Patients and evaluators will be blinded. Both DISCOGEL® and HYDROCORTANCYL 2,5 POUR CENT are authorized products used according to their intended use. This is an interventional, prospective, national, multi-center, comparative, randomized, single-blind (patient and evaluator) post-market clinical study. The primary objective is to compare the short-term efficacy profile of DISCOGEL® versus intradiscal steroid.
