Purposes of the study and background

Pain of lumbar facet-joint origin is a common cause of low back pain in adults, and may lead to chronic pain and disability. At present, there is no definitive research to support the use of targeted lumbar facet-joint injections to manage this pain.

The study's objective was to assess the feasibility of carrying out a definitive study to evaluate the clinical- and cost-effectiveness of lumbar facet-joint injections compared to a sham procedure.

Summary of methods and results

This was a blinded parallel two-arm pilot randomised controlled trial. Adult patients referred to the pain and orthopaedic clinics at Barts Health NHS Trust with non-specific low back pain of at least three months' duration were considered for inclusion.

Participants who had a positive result following diagnostic single medial branch nerve blocks were randomised to receive either intra-articular lumbar facet-joint injections with steroid or a sham procedure. All participants were invited to attend a combined physical and psychological programme.

Questionnaires were used to assess a range of pain and disability-related issues. Healthcare utilisation and cost data were also assessed.

Of 628 participants screened for eligibility, 9 were randomised to receive the study intervention and 8 participants completed the study.
