Degenerative spondylosis is a somewhat broad medical term used to describe age-related degeneration, or breakdown, of the spine. If your orthopedic physician diagnoses you with spondylosis, he or she is telling you that your back or neck pain—and other related symptoms—are age-related, a result of the normal wear and tear of living.
If you have this form of spondylosis, some part of your spine, be it the vertebrae themselves, the discs between them, or the surrounding cartilage or ligaments, has broken down to the point where your joints have become affected—contributing to another condition such as osteoarthritis, spinal stenosis, or compression of your nerves (leading to issues like sciatica).
Occasionally, people will ask the question, “Is spondylosis the same thing as degenerative disc disease, or DDD?” The answer is “basically, yes.” The terms are often used interchangeably. (A third term, more accurate than DDD, is “disc degeneration.”)
Spondylosis may be the initial diagnosis used to describe age-related back or neck pain, and maybe some numbness or tingling in your legs or feet. Upon further examination and testing, your orthopedist may find that the specific source of your spondylosis, as well as its effects; for example, you may have a worn lumbar disc that’s causing two vertebrae in your lower back to grind against each other, triggering the growth of bone spurs that put pressure on your surrounding nerves.
Some orthopedists prefer to use the word spondylosis over the term degenerative disc disease because the condition is not truly a disease, but a mechanical issue—the gradual breakdown of the discs between the vertebrae due to the ordinary wear and tear of aging. (Or in some cases, the wear and tear brought on by traumatic injury.)
Also, this type of wear-and-tear is not a degenerative condition in the classic sense, in that it isn’t caused by changes in the body at the cellular level—nor does it get predictively, progressively worse over time. (However, osteoarthritis—a frequent and perhaps inevitable result of disc degeneration—is degenerative, which is why the terms are often used interchangeably.)
Spondylosis can happen to anyone—in fact, an estimated 80% of men and women over 40 are likely to show some sign of spinal degeneration on their X-rays. People with symptoms tend to first notice them between the ages of 20 and 50.
If you notice symptoms at a younger age, there may be a genetic component to your particular case. Having a history of injuries can also increase your likelihood of developing spondylosis. For example, some studies indicate that whiplash sustained in a car accident may make you more likely, years after the accident, to get surgery to repair or remove a damaged disc.
But for the most part, spondylosis is the result of aging. Most people will experience it as they get older, but not everyone will require (or desire) a medical intervention.
As we age, our discs lose water and proteins; they dry out, becoming stiff and brittle. Repetitive stress to the neck or back can create micro-tears and other traumas in the outer shells.
Activities that used to be easy—bending over to pick up a delivery box, swinging a golf club, or even twisting around to say hello to someone behind you at the store—may lead to a disc injury or slipped disc. Unfortunately, these injuries don’t repair themselves as easily when we’re older.
The discs’ isolation within the spinal column means they don’t have the same access to a nutrient-rich blood supply as other types of collagen/cartilage in the body (for example, the outer parts of the knee, the elbow, or the Achilles tendon). They can’t self-repair quickly. Pair this with the loss of water and proteins due to the natural aging process, and this means we sustain damage to our necks and backs that may take a good deal of time to fix—or the help of a doctor.
Disc degeneration usually occurs in the cervical vertebrae (the neck) or in the lumbar vertebrae (the lower back). After testing, your orthopedist may diagnose you with cervical spondylosis or lumbar spondylosis.
The types of symptoms that you experience will depend on the extent of the damage to the affected intervertebral disc and how that damage creates a domino effect on the surrounding nerves, bone, and tissue.
Common responses to spondylosis include:
Different people experience disc degeneration in different ways, with varying manifestations. Symptoms can differ depending on the location and the specific type of disc degeneration, and what that breakdown of the disc is doing to surrounding nerves and tissue. You may barely notice a problem, whereas someone else may experience numbness in their extremities or chronic pain in their lower back or neck.
If you have spondylosis, you may notice one or more of the following, depending on the specifics of your case:
If you think you may have spondylosis and your symptoms are interfering with your quality of life, your next step is to make an appointment to see a doctor. Spondylosis needs to be confirmed with lab testing like X-rays, CT scans, or MRIs.
Once you’ve been diagnosed, you and your orthopedist can work together to discuss your options for treatment. To discuss further please contact Coastal Orthopedics today at (361) 994-1166.
