About this trial

This study concerns the treatment of recent lumbago and aims to evaluate the efficacy of an anesthetic block of the erector spinae muscles combining ropivacaine and dexamethasone. This treatment is routinely used in several institutions in France, but has never been the subject of a randomized placebo-controlled study to assess its efficacy at D4 of treatment.

The BLOCLOMB comparative, randomized, double-blind study aims to validate the efficacy, over the first 4 days, of anesthetic blocks of the erector spinae muscles, during recent lumbago, on the pain of muscular contractures.
