Cervical spondylosis refers to common age related changes in the area of the spine at the back of the neck. With age, the vertebrae (the component bones of the spine) gradually form bone spurs, and their shock absorbing disks slowly shrink. These changes can alter the alignment and stability of the spine. They may go unnoticed, or they may produce problems related to pressure on the spine and associated nerves and blood vessels. This pressure can cause weakness, numbness, and pain in various areas of the body. In severe cases, walking and other activities may be compromised.
As people age, shrinkage of the vertebral disks prompts the vertebrae to form osteophytes to stabilize the back bone. However, the position and alignment of the disks and vertebrae may shift despite the osteophytes. Symptoms may arise from problems with one or more disks or vertebrae. Osteophyte formation and other changes do not necessarily lead to symptoms, but after age 50, half of the population experiences occasional neck pain and stiffness.
STATISTICS: A total of 47,560 patients were included in this study. Cervical spondylosis occurred in 13.1% overall, but was found in 31.0% of patients with thoracolumbar spinal deformity (OR=3.27, P<0.0001). Similarly, thoracolumbar spinal deformity was found in 10.7% of patients overall, but was increased at 23.5% in patients with cervical spondylosis (OR=3.26, P<0.0001). In addition, increasing severity of disease was associated with an increased likelihood of the other spinal diagnosis. Patients with both diagnoses were more likely to undergo both cervical (OR=3.23, P<0.0001) and thoracolumbar (OR=4.14, P<0.0001) spine fusion.
