[Lumbar osteoarthritis]

Lumbar osteoarthritis involves both the disc and the facet joints. Measurements of the disc space evaluates the degeneration. There is no radio-clinical correlation at a given time. There are however inflammatory phases in facets arthrosis and discolysis with disc narrowing within few months. These attacks are responsive to NSAID'S and local injections of corticosteroids. The chronic back pain needs only analgesics and rehabilitation. Osteophytes can narrow the spinal canal and induce back and leg pains. Except neurological weakness and bladder dysfunction the medical treatment should be prolonged before the indication of surgery.
