Lumbar Facet Joint Injection
Facet joints can be a common source of chronic low back pain. Facet joints are thought to play a part in 15% to 45% of patients with low back pain, 54 to 67% of patients with neck pain and 48% of patients with thoracic pain.
Diagnostic and Therapeutic
Goldthwait in 1911 first described lumbar facet joints as a source of back pain. In 1933, Ghormley coined the term facet syndrome and defined it as a lumbosacral pain (with or without sciatic pain) that occurs after a twisting or rotary strain to the lumbosacral spine. In 1963 that Hirsch et al injected hypertonic saline into facet joints and experimentally reproduced low back pain along the sacroiliac and gluteal areas with radiation to the greater trochanter. In 1976, Mooney and Robertson, followed by McCall et al. in 1979, used fluoroscopic guidance for facet joint injection with steroids and local anaesthetics.
