In most cases, spondylosis results from the cumulative effects of ongoing wear and tear on the spine. However, there are a number of risk factors that can increase your likelihood to develop spondylosis. These risk factors include obesity, genetic predisposition, a history of traumatic injuries and participation in high-impact sports.
Specifically, spondylosis occurs when the soft tissues in the spinal anatomy — the spinal discs, tendons, muscles, ligaments and cartilage that lines the facet joints — naturally deteriorate over time. For instance, the spinal discs, which are normally saturated with water, can become dehydrated and lose their effectiveness as cushions between the vertebrae. The cartilage in the facet joints can gradually wear away, resulting in bone-on-bone contact between the joints. This friction can cause inflammation and trigger the body’s natural protective responses, including the production of smooth bony deposits (bone spurs or osteophytes) in the affected areas. Additionally, the muscles that support the spine can weaken, while ligaments and tendons can thicken, tighten and stiffen.
