However, there has been no published study providing scientific evidence by prospective randomized data on the effect of LDRT in patient suffering from facet osteoarthritis. LDRT seems a viable treatment method with anti-inflammatory potential and possible long-lasting benefit in pain resolution for patients with facet joint arthritis (FJA), which can prevent from an ultimate surgical treatment.~The rationale of this trial is to generate scientific evidence that LDRT is an alternative non-invasive treatment option for FJA, whose primary outcome pain reduction is equivalent to the most common treatment intra-articular steroid injections.
The goal of this clinical trial is to compare low-dose radiation therapy (LDRT) with intra-articular steroid injections in participants suffering from chronic lower back pain as cause of facet joint arthritis (FJA).~The main question[s] it aims to answer are:~Is LDRT non-inferior to intra-articular steroid injections in terms of pain reduction~Is there a difference in long-term pain reduction between LDRT and intra-articular steroid injections Participants will be randomly assigned to one of the two treatment groups.
