Spondylosis Deformans

What is spondylosis?

Spondylosis deformans is a condition that affects the vertebral bones of the spine. It is characterized by the presence of bone spurs or osteophytes (bony prominences) along the edges of the bones of the spine. A bone  spur or osteophyte may develop in a single spot on the spine, or there can be multiple bone spurs in several different locations along the spine (more common). The most common places that spondylosis deformans lesions develop are along the thoracic vertebrae (upper back), especially at the thoracolumbar junction between the rib cage and the abdomen, in the lumbar spine (lower back), and in the lumbosacral spine (where the lumbar spine meets the pelvis). In some cases, the bone spurs may become large enough that they appear to form a complete bridge between adjacent vertebral bones. This is sometimes called “bridging spondylosis”.

Spondylosis deformans is a chronic condition that is associated with aging or excessive motion at the spine. Research indicates that it often develops as a secondary problem related to degenerative disease of the intervertebral discs that sit between each spinal vertebra. In the normal spine, the vertebral bones are joined by ligaments to form a flexible protective column around the spinal cord. The intervertebral disc between each vertebral bone acts as a shock absorber or cushion, and the series of joints that make up the spine give the back flexibility of motion while also protecting the delicate spinal cord from damage. Spondylosis causes a decrease in mobility and stiffness through the spine.
