Implication for health policy/practice/research/medical education: The lifetime prevalence of chronic osteoarticular pain has been reported to be as high as 60%, in this observational study we evalu-ated the efficacy of PRF in the treatment of lumbar chronic facet joint pain. 1. Background Low back disorder is the most common problem in the entire spinal axis. About two-thirds of adults suffer from low back pain (LBP) at some time (1). Pain gen-erators in the lumbar spine include the annulus of the Background: Low back disorder is the most common problem in the entire spinal axis. About two-thirds of adults suffer from low back pain (LBP) at some time. Pain generators in the lumbar spine include the annulus of the disc, the posterior longitudinal ligament, a portion of the dural membrane, the facet joints, the spinal nerve roots and ganglia, and the associated paravertebral muscle fascia. There is no doubt that the facet joint is a potential source of chronic LBP. Facet joints are true synovial joints that have a joint space, hyaline cartilage surfaces, a synovial membrane, and a fibrous capsule. Two medial branches o
