This page deals with basic information on the lumbar facet joints and how they cause pain. The lumbar facet joint can lead to pain like any other joint in the body. Bone spurs or other arthritic conditions lead to decay of the joint surfaces and this causes the joints to rub against their bony surfaces and this causes inflammation. The inflammation leads to further joint decay and pain. Arthritis is a natural condition associated with aging but it can be worsened by stresses or trauma. There is no "cure" for the arthritis but there are treatments or cures for the pain associated with the arthritis.
