An in vitro analysis of the size and shape of cryolesions for facet joint denervation

Lumbar facet joint syndrome (LFJS) is the cause of pain in 15 –54% of patients with low back pain. LFJS was first described by Ghormly in 1933 [1]. Clinically, LFSJ is characterised by a deep dull pain in the lower back, which often radiates into the leg and may be difficult to localise. The pattern of radiation is not radicular unless there is a concomitant nerve root compression. Often, the pain worsens with physical strain and can be provoked by lateral bending and/or hyperextension. Pain can sometimes be elicited by pressure on the affected joint, and neurologic exams are usually normal.
