Overview
Brief Summary
The prevalence of low back pain is estimated at 90% . Recent studies have shown that 15% to 52% of back pain is attributable to facet joint syndrome .
Being the only vertebral joints provided with a synovial membrane, the posterior inter-apophyseal joints are subject, like all other peripheral joints, to degenerative arthritis phenomena.
These phenomena most often result in the release of pro-inflammatory cytokines resulting in cartilage degradation.
PRP or platelet rich plasma is an autologous blood product obtained after centrifugation of a peripheral blood sample. The PRP has many anti-inflammatory properties. Numerous studies have shown the interest of intra-articular infiltration of PRP in osteoarthritis of the knee but also in tendinopathies of the shoulder and a few studies also suggest the use of PRP in the spine "intra-disc, epidural and posterior joints) .
Corticosteroid infiltrations in the posterior lumbar joints constituting the standard treatment in posterior inter-apophyseal osteoarthritis.
The goal is to obtain a new therapeutic weapon in the management of this frequent and invalid disease for patients who are often elderly and with other comorbidity.
Detailed Description
This is a randomized controlled trial, of superiority, which aims to demonstrate that in low back pain induced by osteoarthritis phenomena affecting the facet joint syndrome, PRP infiltrations are greater than that of corticosteroids. In the context of this study, the patients will have an infiltration of PRP or an infiltration of corticosteroids (the infiltration of corticosteroids corresponds to the usual management of patients with low back pain attributable to posterior inter-apophyseal osteoarthritis). It has already been shown, in particular in osteoarthritis of the knee that PRP infiltrations do better than local corticosteroid infiltrations at 6 months, with a comparable safety profile. In low back pain attributable to posterior inter-apophyseal osteoarthritis, the therapeutic possibilities are limited and include either corticosteroid infiltration initially or a surgical intervention. Corticosteroid injections are the standard treatment, but the maximum limitation of 3 injections per year and the presence of medical contraindications (hypertension, diabetes or uncontrolled infection, etc.) or even operative ones, lead to a therapeutic impasse. If the investigators show superiority over prednisolone infiltrations, PRP infiltrations may be provided to these patients.
