Osteoarthritis of the Lumbar Spine

Osteoarthritis of the Lumbar Spine BACK PROBLEMS JAMA PATIENT PAGE The Journal of the American Medical Association p to 80% of people experience low back pain at some time. Osteoarthritis, a common cause of low back pain, involves breakdown of cartilage (tissue covering the joint surfaces at the ends of bones). The July 7, 2010, issue U of JAMA includes an article showing that glucosamine is not effective in treating osteoarthritis of the spine. PATHOLOGY Normal joints move easily because healthy cartilage cushions the bones as they move against each other. In spinal osteoarthritis, the cartilage lining the facet joints (vertebral joints) wears out, allowing the bones to rub together. Osteophytes (small bony growths also known as bone spurs) form on facet joints and around vertebrae in an attempt to return stability to the joint. Gradually, the spine stiffens and loses flexibility. Osteophytes sometimes become large enough to cause narrowing of the spinal canal or foramen, irritating or entrapping nerves passing through them (spinal stenosis and foraminal stenosis). Stenosis, while related to osteoarthritis, is a separate medical condition. Osteoarthritis can also be confused with degenerative disk disease, a gradual deterioration of disks between the vertebrae, but is a separate medical condition.
