About
Degenerative disc disease (DDD) is a major cause of chronic low back pain (> 40%). It can be defined by specific magnetic resonance imaging (MRI) features, with a strong correlation between pain and the inflammatory aspect of the disc, resulting in active disc disease (AD). The Modic classification based on MRI of the lumbar spine is considered a reference.
The management of low back pain in patients with inflammatory disc disease generally involves intra-disc corticosteroid infiltration, which has been widely proven to be effective in reducing pain [4-6]. However, this procedure can be painful and invasive and sometimes impossible to perform due to severe disc impingement.
The aim of this study is to evaluate the efficacy on pain of para-disc infiltration of corticosteroids in contact with the inflammatory MRI signal abnormality (Modic 1) when it is lateralized.
This variant of infiltration is easier to perform (no catheterisation of the disc and therefore quicker), would entail less risk of disc infection and would be accessible to more radiologists.
It is already practised but, to our knowledge, has never been the subject of a study to evaluate its effectiveness on pain.
If successful, more patients could be treated and the range of treatment could be extended.
